DescriptionMaterial:Housing plastic
Raceways ball bearing steel.
Balls steel.Note:The linear ball bearings correspond to the self-aligning series 3 of ISO 10285. With double-sided seal. These bearings consist of high precision injection moulded plastic housings in which ball bearing steel raceway segments are clipped in. The plastic housing serves simultaneously for recycling and as seal retainer. The seal consists of a special polyamide material with a low coefficient of friction. 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.Special features: DownloadHere is all the information as a PDF datasheet:
