DescriptionMaterial:Outer jacket ball bearing steel.
Cage plastic.
Balls steel.Note:The linear ball bearings correspond to series 3 of ISO 10285. With double-sided seal. The linear ball bearings have a plastic cage which results in quiet and outstanding running properties. We recommend using linear ball bearing with steel cages for application temperatures over +80 °C. The bearings are secured by DIN 471/472 circlips.

Recommended tolerances:
Shaft: h6
Housing: H7

Linear ball bearings with double-sided seal should be greased before installation.

The specified load ratings apply with the use of hardened and ground shafts.Temperature range:-20 °C to +80 °C.Special features:
