Small silver cylindrical bearing with hex socket stud end

Smith Bearing

Smith Bearing CR-1/2-B Needle Roller Cam Follower 1/2 in Diameter #10-32 Stud Hex Socket Unsealed

SKU CH-X5CV-FVT3E

Needle roller cam follower with a 1/2 in diameter and #10-32 concentric stud

  • Needle rollers handle high radial loads in tight spaces
  • AISI 52100 alloy steel resists wear under repeated cycling
  • Concentric #10-32 stud simplifies alignment during installation
  • Hex socket drive allows torque adjustment without special tools
  • Unsealed design suits lubricated environments where contamination is low

Compact Needle Roller Cam Follower

The Smith Bearing CR-1/2-B is a stud-type needle roller cam follower built for inch-system power transmission. It suits linear motion tracks, indexing mechanisms and light-duty automation where a compact rolling element is required. The concentric stud mounts directly into a tapped hole without an eccentric adjuster.

Check Stud Thread and Clearance

Verify that the mating hole accepts a #10-32 thread and that the 1 1/32 inch overall length fits the available stack-up. Confirm the 3/8 inch roller width matches the track or cam profile you are running. Ensure the unsealed design is acceptable for the operating environment and lubrication plan.

Unsealed Construction Affects Maintenance

The open closure means no integral seals retain grease or exclude contaminants. Users must supply and replenish lubrication appropriate to the application. The hex socket drive allows installation with a standard hex key, and the AISI 52100 alloy steel needle rollers provide the stated load capacity.

Questions about this item

Does the CR-1/2-B cam follower include any mounting hardware or seals, or must those be sourced separately?

The follower is supplied as a single unsealed unit with a concentric #10-32 stud and integral hex socket; no nuts, washers, seals or lubrication fittings are included, so any required mounting hardware or sealing components must be purchased separately.

How do I decide between the standard-duty CR-1/2-B and a heavy-duty variant for my application?

Choose the standard-duty CR-1/2-B when loads and speeds fall within typical needle-roller limits for a 1/2 in diameter, 3/8 in wide roller; step up to a heavy-duty version only if the manufacturer’s catalogue shows your radial load or speed exceeds the standard rating for this envelope.

What does the 52100 alloy steel rating mean for real-world wear life in a cam-driven mechanism?

AISI 52100 bearing-grade steel provides high hardness and fatigue resistance, giving predictable rolling-contact life in properly lubricated cam tracks; actual service intervals depend on load, speed, alignment and lubrication maintenance rather than the material grade alone.
