Bearings & Power Transmission — Australia's Industrial Supplier
AIMS Industrial carries a comprehensive range of bearings and power transmission products for maintenance, engineering and manufacturing operations across Australia. With 250+ products from leading brands, this collection covers bearings, belts, pulleys, couplings, key steels, chains and O-rings.
Bearings
The bearing range spans deep groove ball bearings from Koyo and NTN, EZO miniature bearings, IJK and JAF self-aligning and angular contact bearings, and FYH housed bearing units. For detailed selection by bearing type — cylindrical roller, tapered roller, spherical roller, needle roller, linear bearings or thrust bearings — use the specific bearing type collections linked from this page.
Belts & Drive Systems
Gates V-belts cover the full classical and narrow section range (A, B, C, AX, BX, 3L), plus Truflex light duty, Fleetrunner micro-V and automotive timing belts. PIX V-belts and PIX M-section provide economical alternatives. Mackay Multicushion isolators and automotive belts cover vehicle applications. Fenner Drives link belts offer easy field installation without shaft disassembly.
Power Transmission Components
Finer Power Transmissions supplies aluminium V-pulleys (A and B section, pilot bore), taper lock bushes in cast iron, jaw couplings with NBR spider elements, and bronze bushes in metric and imperial. Precision Brand and Finer supply metric and imperial key steel in zinc plated and 304 stainless steel. Tsubaki and SY Chain roller chain covers BS and ASA pitch in standard and heavy series. NBR O-rings in metric and imperial cross-sections are stocked for sealing and replacement applications.

People Also Ask — Bearings and Power Transmission
Q: What does 'power transmission' cover in AIMS's range?
Power transmission encompasses everything between the motor and the driven load: bearings (ball, roller, thrust), couplings (rigid, flexible, fluid), shaft components (collars, keyways, taper-lock bushes), belts and pulleys (V-belt, timing, flat), chains and sprockets, gear reducers, and torque limiters. The category supports motors, conveyors, machinery, and any mechanical drive system. AIMS stocks Gates, NSK, Koyo, NACHI, FYH, and Finer brands across this range.
Q: How do I select a bearing for my application?
Five questions: (1) what load is the bearing supporting — radial only, thrust only, or combined? (2) What speed will it run at? (3) What's the shaft diameter? (4) What's the operating environment — clean workshop, dusty, wet, high-temperature? (5) What life expectancy do you need? Match to bearing type: deep-groove ball for general purpose, roller for heavy radial, thrust for axial loads, sealed for contaminated environments.
Q: Belt drive or chain drive — which?
Belt drive: quieter, doesn't need lubrication, tolerates misalignment, cheaper per Nm. Best for higher-speed lower-torque applications, clean environments. Chain drive: higher torque capacity per inch of width, no slip, longer life under heavy load, but needs lubrication and is louder. Best for low-speed high-torque heavy-duty drives. Many industrial applications run V-belts on motor drives; conveyor and mill applications often run chains.
Q: How do I match a coupling to my shaft sizes?
Two shaft bores must match the shaft diameters they connect (e.g. 28mm motor shaft + 32mm gearbox shaft). The coupling spec lists max bore for each side. Then size the coupling by torque rating — should exceed your peak system torque with safety factor. Then consider misalignment tolerance: rigid coupling for precisely-aligned shafts, jaw coupling for general use with elastomer spider, gear coupling for heavy industrial. Service factor 1.5-2× for shock loads.
Q: How long should industrial bearings last?
Manufacturers rate bearings by L10 life — the time at which 90% of bearings will still be running. Typical L10 in clean conditions is 10,000-50,000 hours depending on load. Real-world life varies: contamination, vibration, misalignment, and inadequate lubrication all reduce life. Quality bearings (SKF, NSK, Koyo, NACHI, FYH) typically reach 90% of catalogue L10. Cheap unbranded bearings often fail at 20-30% of rated life — false economy.
