Smith Bearing FCR-1-1/4 Track Roller

The Smith Bearing FCR-1-1/4 is a stud-type track roller built for heavy-duty linear motion and cam-follower applications. Its concentric stud and flanged head suit machinery builders who need reliable radial guidance on flat or channeled tracks. The open closure and single row of rolling elements keep the design straightforward for maintenance and inspection. It is not for buyers who need integral seals or a double-row load capacity.

Thermals noise and power draw

As an unpowered mechanical component the roller generates no electrical heat and draws no current during operation. Running noise stems only from contact between the alloy-steel rolling elements and raceway under load. Frictional warmth stays minimal in normal service because the plain face design avoids sliding friction. No cooling or lubrication system is required beyond standard bearing grease intervals.

Build quality connectors and mounting

The roller body and stud are both made from alloy steel with the bearing grade rated to AISI 52100 for wear resistance. A 1/2 In. -20 thread on the concentric stud allows secure fastening into a tapped hole or nut without eccentric adjustment. Overall length measures 2 5/32 in with a roller width of 27/32 in and a flange diameter of 1-1/4 in. The plain face suits flat-track running but does not accommodate crowned or V-groove profiles.

Questions about this item

How do I install the stud on the FCR-1-1/4 track roller and what step is commonly missed?

Thread the 1/2 In. -20 concentric stud into the mounting hole and torque to the equipment specification; the step often missed is verifying the stud shoulder seats fully against the housing before tightening.

What maintenance or replacement will the FCR-1-1/4 track roller need over time?

The open closure has no seals, so schedule periodic relubrication of the single-row AISI 52100 bearing and inspect the alloy-steel flanged roller face for wear; replace the unit when radial play exceeds the equipment tolerance.

What is the first limit reached on the FCR-1-1/4 track roller under sustained heavy loading?

The dynamic radial load capacity of 1,350 lbf is the primary limit; exceeding it accelerates bearing fatigue and roller deformation before any other factor becomes critical.
