ENC 608-2RS-250C 250°C High Temperature Sealed Deep Groove Ball Bearing 8 x 22 x 7 mm

This ENC 250°C range covers 37 single row deep groove ball bearings with two vulcanised rubber contact seals (2RS) in the 600, 6000, 6200 and 6300 series, from 8 to 60 mm bore and 22 to 110 mm outer diameter. Select the size from the drop-down: each size has its own bearing number and dimensions, and the sizes with published figures also list mass, speed and static load.

The bearings are made from AISI 52100 steel with C4 radial clearance, which is larger than Normal and larger than C3. They are factory greased for -20°C to 265°C, and the vulcanised rubber seals carry 265°C protection, so the seals hold the grease in and keep dust and splashes out.

Key specifications

Available sizes

A dash means no figure is published for that size, so only its dimensions are given.

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 suits a lower speed than an open or shielded bearing of the same size.

This range is the ENC 250°C range: the grease is specified from -20°C up to 265°C and the seals carry 265°C protection. For a higher temperature range, or if the working temperature, speed and load are close to the figures for your size, confirm the choice with AIMS before ordering.

Fitting and use

Check the load, speed and working temperature against the figures for your size before ordering and apply a suitable safety factor.

ENC bearings are greased at the factory. Do not wash the grease out.

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.
