RTR Ball Bearing:
deep groove ball bearing
Deepgroove ball bearing are particularly versatile.They are simple in design, non-separable,suitable for high and even very high speeds and are robust in operation,requiring little maintenance.Deep raceway grooves and the close conformity between the raceway grooves and the ball enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads,even at high speeds.Single row deep groove ball bearings are the most widely used bearing type.

Angular contact ball bearing
Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis.This means that they are designed to accommodate combined loads,i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing congtact angle.

Thrust ball bearing
Thrust ball bearings consist of a shaft washer,a housing washer and a ball and cage thrust assembly.Th bearings are separable so that mountingg is simple as the washers and the ball and cage assemble can be mounted separately.Thrust ball bearings ,as their name s ests,can accommodate axial loads in one direction and thus locate a shaft axially in one direction.They must not be subjected to any radial load.

Self-aligning ball bearing
Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.
