  • Double-sealed contact closure keeps contaminants out

Smith Bearing HR-3-XB cam follower

The Smith Bearing HR-3-XB is a heavy-duty needle roller cam follower built for power transmission systems that demand high load capacity in a compact inch-format design. It suits engineers and maintenance teams specifying reliable track-roller motion for industrial machinery and automation equipment.

Sustained load behaviour

Double contact seals protect the single row of AISI 52100 alloy steel needle rollers from contamination during continuous operation. The carbon steel concentric stud and heavy-duty construction maintain alignment and resist deflection when the follower runs under prolonged or repetitive loading cycles.

Interface practical limits

The 1 1/2 In.-12 stud thread and hex socket drive require matching threaded mounting holes and a hex key for installation. The inch-system dimensions and concentric stud type limit direct interchangeability with metric or eccentric-stud alternatives without adapter hardware.

Questions about this item

How much heat does the AISI 52100 needle roller generate under continuous heavy-duty operation?

The alloy steel roller and carbon steel stud are built for heavy duty, and the double contact seals help retain lubrication to manage temperature during extended runs.

What shaft or mounting hardware must I already have to install the 1 1/2-12 stud on this follower?

You need a mating tapped hole or nut with a 1 1/2 In. -12 thread, plus a hex key that fits the stud's hex socket drive for installation.

Will the 3 in flat roller work on the same track as my older 2 1/2 in cam followers?

The 3 in diameter and 1 3/4 in width change the contact geometry, so the track must match these dimensions for proper engagement.
