QJ309M Four Point Contact Bearing 45x100x25

Four point contact bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.

C3: Axial internal clearance larger than normal
MPA: Solid brass cage
TVP: Window cage made from glass fibre reinforced polyamide 66
N2:Two retaining slots in outer ring

The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. The two-piece inner rings allow a large complement of balls to be accommodated. The inner ring halves are matched to the particular bearing and must not be interchanged with those of other bearings of the same size. The outer ring with the ball and cage assembly can be mounted separately from the two inner ring halves.

Bearings with solid brass cages can be used at operating temperatures from –30 °C to +150 °C. Bearings with an outside diameter of more than 240 mm are dimensionally stable up to +200 °C.
