QJ 234 N2MA
Additional Details
Four-point contact bearings can withstand high axial loads in both directions and small radial loads. They can operate at very high speeds and are more suitable than deep groove ball bearings for axial load support. The outer ring, consisting of balls and cage, can be mounted separately from the two inner rings.
