ENC 607-ZZ-270C 270°C High Temperature Shielded Deep Groove Ball Bearing 7 x 19 x 6 mm

This ENC 270°C range covers 58 single row deep groove ball bearings with two metal shields (ZZ) in the 600, 6000, 6200 and 6300 series, from 7 to 90 mm bore and 19 to 190 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 a manganese phosphate surface treatment and increased radial clearance to compensate for thermal expansion. They are factory greased with Klüber Barrierta LT 55/2 grease, specified from -30°C up to 270°C, and the two metal shields hold the grease in and keep larger particles out without touching the inner ring.

Key specifications

Available sizes

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

Selecting the right option

Metal shields (ZZ) retain the grease and keep larger particles out without touching the inner ring. A shield is not a seal: fine dust and moisture can still enter, so choose a contact-sealed bearing where dust, splashes or damp are present.

This range is the ENC 270°C range: Klüber Barrierta LT 55/2 grease is specified from -30°C up to 270°C. 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.
