DescriptionMaterial:Housing plastic
Raceways ball bearing steel.
Balls steel.Note:The linear ball bearings correspond to series 3 of ISO 10285. With double-lip seal both ends. In comparison to standard linear ball bearings, these bearing have twice the load rating or eight times longer working life. The self-aligning function means that housing bore misalignments or bent shafts can be compensated for, the load distribution optimised and uniform load on all balls over the entire bearing length assured. The bearing is secured with 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: DownloadHere is all the information as a PDF datasheet:
