EZO SS6300-2RS Sealed Stainless Miniature Ball Bearing 10 x 35 x 11 mm

This EZO range covers 8 stainless steel single row deep groove ball bearings, sealed (2RS), from 10 to 35 mm bore, with outer diameters of 35 to 80 mm and widths of 11 to 21 mm. Select the size from the drop-down: each size has its own bearing number and dimensions, load ratings and limiting speed in the Model Details.

Deep groove bearings are the most widely used ball bearing type. They carry radial loads and axial loads in both directions, run at high speed and need no adjustment. The rings and balls are stainless steel, which resists corrosion much better than standard bearing steel in damp or mildly corrosive conditions. The two contact rubber seals (2RS) hold the grease in and keep dust and splashes out.

Where this product is used

• Equipment exposed to moisture, humidity or mild corrosive conditions
• Pumps, conveyors and packaging machinery
• Electric motors, fans and light industrial machinery

Features

• Two contact rubber seals (2RS) of nitrile rubber (NBR) hold the factory grease in and keep dust, dirt and splashes out
• Stainless steel rings and balls resist corrosion much better than high carbon chromium steel, for use in damp or mildly corrosive conditions
• Basic dynamic load ratings 6.87 to 28.29 kN and static load ratings 2.75 to 15.27 kN across the range

Key specifications

Available sizes

Limiting speed is the grease rating for the size; contact seals reduce it.

Selecting the right option

Contact rubber seals (2RS) give better protection against dust, dirt and splashes than shields and hold the factory grease in. The seal lips add friction, so a sealed bearing runs slower than an open or shielded bearing of the same size, and a high speed application is better served by an open or shielded bearing.

The rings and balls are martensitic stainless bearing steel. It resists corrosion far better than standard high carbon chromium steel, but not as well as 304 or 316 stainless, so it is not suited to seawater, acids or continuous immersion. Match the bearing to the fluids and cleaning agents in the application.

Fitting and use

Check the load and speed against the figures for your size before ordering and apply a suitable safety factor. Deep groove bearings must always carry a minimum radial load so the balls roll rather than slide, and heavy axial loads should be checked with AIMS before ordering.

Press on the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and through the outer ring in a housing.

Sealed bearings are lubricated at the factory and built for inner ring rotation. Do not wash them or heat them before mounting, and do not rely on them for high speed outer ring rotation.
