ReviewsSingle direction Thrust Ball Bearing

SKF F4B 108-RM Ball Bearing Flange Unit, 4 Bolts, Set Screw Locking, Regreasable, Contact Seal, Cast Iron, 1-1/2\ Bore, 4\ Bolt Hole Spacing, 6900lbf Dynamic Load Capacity

Double-sealed, deep-groove ball bearing insert for applications with radial, thrust, and combined loads.
Cast iron housing and steel bearing unit for carrying shafts with radial or radial and thrust loads.
Set screw locking for secure attachment to shaft.
Contact seals on both sides of the bearing keep lubricant in and contaminants out.
Grease fitting on the housing for reapplying lubricant.

Low friction: The ball does not cycle and can achieve rolling motion with minimal friction..
High precision linear movement: as part of shaft and nut, the clearance in rotation direction can be adjusted to ensure accuracy..
Transferable rotating torque: the ball rolls on the ball groove of the spline shaft and moves in a straight line while transferring the rotating torque..
Compact design: even a single shaft mechanism can move in a straight line, while keeping the nut in the direction of rotation without deviation..
Large bearing capacity and long service life: Because the rolling surface adopts r-shaped ball groove matching with the ball diameter, the contact area is large, the bearing capacity is strong and the service life is long..
