BECO High-Temperature Bearings
BECO specialises in high-temperature and extreme-temperature deep groove ball bearings — bearings built to keep running where a standard bearing and its lubricant would fail. The range at AIMS spans continuous operating temperatures from around 150°C up to 350°C, in the seal, shield, cage and coating options that suit different heat and contamination conditions. Because BECO high-temperature bearings are built to standard bearing boundary dimensions, they drop into the same housings and shafts as the standard bearing they replace — so a hot-running application can be upgraded without re-engineering the mount.
BECO Range at AIMS Industrial
AIMS Industrial stocks BECO high-temperature and extreme-temperature deep groove ball bearings, including the 608 transmission size, across a range of temperature ratings and closures — Viton (FKM) sealed, standard sealed, shielded, open, and graphite-cage variants, with Kiln Black coated options for kiln and furnace duty. For a BECO size or rating outside the stocked range, contact us with the bearing number and the operating temperature and we'll confirm availability.
BECO Range — Quick Reference by Temperature
| Temperature Band | Typical BECO Configuration | Best For |
|---|---|---|
| High temperature — to ~150–200°C | Sealed and shielded deep groove ball bearings; Viton (FKM) sealed variants | Ovens, dryers, hot-air plant, motors in hot environments |
| High temperature — to ~250°C | Viton sealed deep groove and 608 transmission bearings | Bakery and food-drying lines, hot fans, process heat |
| Extreme temperature — to ~270–320°C | Shielded, open and Kiln Black coated deep groove ball bearings | Kilns, furnaces, curing ovens, foundry and ceramic plant |
| Extreme temperature — to ~330–350°C | Open and graphite-cage deep groove ball bearings | Very high heat where seals and standard lubricants can't survive |
As temperature climbs, the seal and lubrication strategy changes: contact seals and packed grease suit the lower high-temperature band, while the hottest applications move to shielded or open bearings with graphite cages that carry lubrication in the cage itself. Confirm the continuous operating temperature and whether the environment is clean or contaminated before selecting — our team can match the BECO rating and closure to the application.
How to choose a high-temperature bearing
Start with the continuous operating temperature at the bearing, not the ambient — a bearing close to a heat source runs hotter than the room. Then consider the closure. Viton (FKM) seals extend the sealed temperature range well beyond standard nitrile (NBR) seals, keeping grease in and contamination out where the heat still allows a seal at all. Shielded bearings block larger debris while tolerating more heat than a contact seal. Open bearings suit the highest temperatures, where any seal or standard grease would break down and lubrication is handled externally or by the cage. Graphite cages carry solid lubrication into the bearing for very high temperatures and low-speed service. Kiln Black coated variants add surface protection for kiln and furnace environments. Contact our team with the temperature, speed, load and environment, and we'll confirm the right BECO configuration.
Dimensional interchange
BECO high-temperature bearings are made to standard deep groove ball bearing boundary dimensions (ISO 15), so a high-temperature bearing of a given number shares the same bore, outside diameter and width as the standard bearing of that number. That means a hot-running application fitted with a standard bearing can usually be upgraded to a BECO high-temperature equivalent of the same size without machining the housing or shaft. Match the bearing number, confirm the temperature rating and closure, and check the internal clearance — high-temperature applications commonly specify greater-than-normal clearance (C3 or C4) to allow for thermal expansion. For cross-referencing, see the bearing cross-reference guide and the deep groove ball bearing guide.

Where BECO high-temperature bearings are used
High-temperature bearings earn their place anywhere a bearing runs hot enough to cook a standard grease or soften a standard seal. Typical Australian applications include kilns and furnaces (ceramics, brick, lime, foundry), industrial ovens and curing plant (powder coating, paint bake, composites), drying lines (food, timber, paper), hot fans and blowers moving heated air, and process equipment in cement, glass and heat-treatment plant. In these settings the bearing sees continuous elevated temperature, and the failure mode is usually lubricant breakdown or seal degradation rather than mechanical overload — which is exactly what a purpose-built high-temperature bearing is designed to withstand.

People Also Ask — BECO High-Temperature Bearings
Q: What is a high-temperature bearing?
A high-temperature bearing is a rolling bearing built to run continuously at elevated temperatures that would degrade a standard bearing — through heat-stabilised rings, high-temperature lubrication or solid-lubricant cages, and seals or shields chosen to survive the heat. Standard deep groove ball bearings are generally rated for continuous service up to around 120°C; above that, standard grease oxidises, standard seals harden, and the rings can lose hardness. High-temperature bearings such as BECO's range are designed specifically for that hotter band.
Q: What's the difference between "high temperature" and "extreme temperature" bearings?
It's a matter of degree and construction. "High temperature" bearings typically cover the band above standard rating up to roughly 200–250°C, often still using a seal (Viton/FKM) and high-temperature grease. "Extreme temperature" bearings push higher again — into the 250–350°C range — where seals and conventional grease can no longer survive, so the design moves to shielded or open bearings, solid-lubricant graphite cages and heat-stabilised rings. BECO's range spans both bands; the right choice comes down to the continuous operating temperature at the bearing.
Q: What is a Viton (FKM) seal and why use it on a hot bearing?
Viton is a trade name for FKM fluoroelastomer, a synthetic rubber that holds up at much higher temperatures than the standard nitrile (NBR) used on ordinary sealed bearings. On a high-temperature bearing, an FKM seal lets the bearing stay sealed — keeping grease in and contamination out — at temperatures where a standard nitrile seal would harden, crack and fail. It's the usual choice for the sealed high-temperature band, before the temperature gets high enough that no seal survives.
Q: Why do the hottest bearings use a graphite cage or run open?
Above the temperature where grease and seals survive, lubrication has to come from somewhere else. A graphite cage carries solid lubricant into the bearing — the cage itself lubricates the rolling contact as it runs, which suits very high temperatures at lower speeds. Open bearings (no seal or shield) are used where the application supplies lubrication externally, or the bearing runs with a solid-lubricant cage, and where letting heat escape matters. Both approaches trade the sealed-for-life convenience of a standard bearing for the ability to survive extreme heat.
Q: Can I use a standard bearing at high temperature?
Only within its rating. A standard deep groove ball bearing with normal grease and nitrile seals is generally limited to continuous service around 120°C; run it hotter and the grease oxidises, the seals harden and service life falls sharply. For sustained operation above that, a purpose-built high-temperature bearing with the right lubrication and closure is the correct choice. If you're unsure of the temperature at the bearing, measure it in service rather than assuming ambient.
Q: Do BECO high-temperature bearings interchange with standard bearings?
Dimensionally, yes — BECO high-temperature bearings are made to standard deep groove ball bearing boundary dimensions (ISO 15), so a given bearing number shares the same bore, outside diameter and width as the standard bearing of that number and fits the same housing and shaft. What changes is the internal construction, lubrication, closure and temperature rating. When replacing, match the bearing number and confirm the temperature rating, closure and internal clearance suit the application.
Q: What internal clearance should a high-temperature bearing have?
High-temperature applications commonly specify greater-than-normal internal clearance — C3 or C4 — because the bearing rings and shaft expand as they heat, which reduces the running clearance from its unmounted value. Fitting a normal-clearance (CN) bearing where the heat calls for C3 or C4 can preload the bearing as it warms and shorten its life. Match the clearance to the equipment specification and operating temperature; if in doubt, contact our team with the application detail.
Q: What's the right lubrication for a high-temperature bearing?
It depends on the temperature band. Through the sealed high-temperature range, a high-temperature grease (for example a polyurea or other high-temperature formulation) replaces standard lithium grease. As temperature rises past what grease can handle, the design shifts to solid lubrication carried by a graphite cage. Don't mix grease types when re-lubricating — different thickeners can be incompatible and break down into a non-lubricating mush. For a high-temperature grease to match a BECO bearing, contact our team.
Q: Where are high-temperature bearings typically used?
Anywhere a bearing runs hot continuously: kilns and furnaces (ceramics, brick, lime, foundry), industrial ovens and curing plant (powder coating, paint bake, composites), drying lines (food, timber, paper), hot fans and blowers, and process equipment in cement, glass and heat-treatment plant. In these settings the limiting factor is heat on the lubricant and seals, not mechanical load — which is what the high-temperature design addresses.
