LFR5301-NPP INA Sealed Track Roller Bearing 12x42x19mm Open Inside diameter d: 27INA Ball bearing track rollers are self retaining, single or double row units with particularly thick walled outer rings.

Designs with a crowned outside surface are used where they are inclined in relation to the mating track and edge stresses must be avoided. Track rollers are available
