Smith Bearing FCR-4 Track Roller
The Smith Bearing FCR-4 is a heavy-duty flanged track roller built for linear motion and guide-rail applications. It uses a tapered roller bearing made from AISI 52100 alloy steel to handle combined radial and thrust loads. The 4 in roller diameter and 2 in width provide a broad contact surface for stability. This unit suits machinery requiring robust, low-friction tracking.
Installation notes for stud mount
The roller mounts via a 1 1/4 in.-12 concentric stud thread directly into a tapped hole or nut. No separate drive components are included, so torque the stud to the equipment manufacturer’s specification. Misalignment during fitting can cause premature bearing wear or flange contact. The open closure means lubrication access must be maintained externally.
Compatibility checks before ordering
Verify that the mounting structure accepts a 1 1/4 in.-12 thread and provides clearance for the 4 in flanged diameter. Confirm the application does not require an integral seal, as the seal type is listed as not applicable. Ensure the operating environment suits alloy steel components without additional corrosion protection. The overall length of 4 13/16 in must fit the available spatial envelope.

Questions about this item
How can I confirm the track roller is rotating smoothly after installation?
Verify that the tapered roller bearing turns freely by hand and listen for quiet operation; the flanged head should stay aligned on the track without wobble.
What components come with the track roller and what must be sourced separately?
The unit includes the alloy-steel stud with 1 1/4 In.-12 threads, flanged roller head, and AISI 52100 tapered roller bearing; mounting hardware and lubrication are not supplied.
Which stud thread size matches my existing mounting hole?
This model uses a concentric stud threaded 1 1/4 In.-12; select it only if your equipment requires that exact thread specification.
