Version
Ground edges.
Technical Data
All bearings are supplied ready for mounting with lubricating grease type KE2P-35 acc. to DIN 51825.
Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.
Housing and shaft tolerances correspond to roundness tolerance class IT2 and perpendicularity tolerance class IT4.
Application
For thread drive bearing.
Temperature range
-30 °C to +120 °C.
Assembly
Precision slotted nuts must be used for mounting the threaded spindles.
To compensate for any material settling during assembly, tighten the slotted nuts using 2x tightening torque, loosen slightly and then tighten using the prescribed tightening torque.
Tighten fastening screws crosswise up to max. 70% of the yield point.
