Description

Product description
Tandem linear ball bearings are standard linear ball bearings in double lengths. Instead of two standard linear ball bearings, one tandem linear ball bearing can be used. Increased accuracy is thus achieved with less design effort.
Material
Outer sleeve, roller bearing steel.
Plastic cage.
Balls, steel.
Note
The linear ball bearings correspond to ISO 10285 series 3. With a seal both ends. The linear ball bearings are have a plastic cage. This makes for quiet running and outstanding run quality.

Recommended tolerances:
Shaft: h6
Housing: H7

Linear ball bearings with a seal both ends should be lubricated before installation.

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