Smith Bearing Product Catalog

Cam Followers (Needle Rollers) Yoke/Stud Type

Cam follower (needle roller) bearings are for applications that have radial loads. They are not intended for axial or thrust loads. Sealed and pre-greased versions are the most common.

  • CR and YR Series (Stud and Yoke Type Cam Followers) are made from high-alloy steel and used where running and shock loads are moderate. Bearing capacity is limited by the moderately sized stud.
  • HR Series (Heavy Stud Type Cam Followers) are made from high-alloy steel and have a larger diameter stud for use in applications with high running and/or heavy shock loads where deflection is held to a minimum. Rollers and outer races are identical to the standard CR series.
  • CR-XB-SS and YR-X-SS (Stainless Steel Cam Followers) are made from 440 stainless steel and intended for applications in harsh environments that require increased corrosion resistance.
  • DCR and DYR Series (Double Row Heavy Duty Cam Followers) have a double row of heavy duty rollers, thicker outer rings, and full-contact seals for improved grease retention.
  • BCR and BYR Series (Non-Metallic Bushing) have non-metallic plastic bushings, which eliminates or reduces the need for lubrication. Continuous feed oil lubrication can be used to reduce wear.
  • MCR and MYR Series (Stud and Yoke Type Cam Followers) metric needle roller bearings are made from high-alloy steel and used where running and shock loads are moderate. Capacity is limited by the moderately sized stud.
  • MUTD and NUKR Series (Double Row Heavy Duty Cam Followers) have a double row of heavy rollers for extremely high load applications. Metallic side shields help to retain grease and keep out contaminants.

SMITH-TRAX Track Rollers

SMITH-TRAX track rollers are high carbon steel or corrosion resistant stainless steel. The internal tapered roller or angular contact ball bearing design is ideal for applications with both high radial and high axial loads. They are available in stud or yoke style with a plain straight, flanged, or v-shaped outer race design.

Ancillary Bearings

Yoke type chain rollers are typically used in fork-lift style equipment or other chain guide applications with a double flanged outer ring design. Spherical plain bearings (GEZ Bearings) are assembled units, with a spherical outside diameter inner ring and spherical inside diameter outer ring. Inner ring races (IRR Series) are hardened and ground and are used as bushings or sleeves. They have radial oil holes and an annular lubrication groove.
