Smith Bearing
Smith Bearing HR-2-1/4-XB Cam Follower Heavy Stud Hex Socket Head bearing
A heavy-stud cam follower with a hex-socket drive and double-sealed needle-roller bearing made from AISI 52100 alloy steel
- Heavy-duty load capacity from alloy steel needle rollers
- Smooth, precise motion via concentric stud design
- Contaminant resistance with double-sealed contact seals
- Easy installation using hex socket drive
- Long service life from AISI 52100 bearing-grade steel
Industrial Cam Follower
The Smith Bearing HR-2-1/4-XB is a heavy-duty needle roller cam follower built for power transmission systems. Its alloy steel construction and concentric stud design suit automated machinery and linear motion applications requiring high load capacity.
Sealed Heavy-Stud Design
The double-sealed contact closure protects rolling elements from contaminants, making it suitable for dirty or wet environments. Buyers needing a lighter stud, a crowned roller face, or an eccentric adjustment feature should select a different model.
1 1/8 Inch -12 Stud Thread
The concentric stud uses a 1 1/8 In. -12 thread for secure mounting in compatible tapped holes. Verify that the mating thread matches this exact specification before purchase.

Questions about this item
How do I install the Smith Bearing HR-2-1/4-XB cam follower using the 12-point hex socket on the stud?
Thread the 1-1/8 in.-12 concentric stud into the prepared hole, then apply torque through the hex socket drive on the stud end; the step often missed is fully seating the flat roller face against the track before final tightening.
What maintenance will the double-sealed needle roller bearing need during its service life?
The contact seals on both sides retain grease and exclude contaminants, so the unit is lubricated for life; no relubrication interval is required unless the seals are visibly damaged.
Which component reaches its load limit first under continuous heavy-duty operation?
The AISI 52100 alloy-steel needle rollers and raceways determine the dynamic capacity; sustained loads beyond their rating will cause subsurface fatigue before the carbon-steel stud or outer ring yields.
