Description

Material
Inner ring, outer ring and rolling elements, bearing steel.
Cage sheet steel.
Labyrinth seal sheet steel. Lip seal NBR.
Version
2Z = sealed both sides with non-contact labyrinth seals.
2RSR = sealed both sides with contact lip seals.
Note
Deep groove ball bearings accept high radial and axial loads. Axial loads are absorbed in both directions. The versions 2Z and 2RSR are lubricated for life with a high quality grease.

The main dimensions of the deep groove ball bearings conform to DIN 625-1. Dimensional and running tolerances correspond to tolerance class PN acc. to DIN 620. The radial internal clearance corresponds to the clearance CN acc. to DIN 620-4. These tolerance classes are standard and well suited for most applications.
Temperature range
-30 °C to +110 °C
