Do You Know Bearing Roller Track Type and Use?

9 Published by admin Oct 23,2026

The global market for roller track bearings continues to see robust expansion, as manufacturers upgrade material formulation, surface hardening and sealing technology to meet growing demand from automated logistics, construction machinery, machine tools and heavy conveyor systems. Market analysts forecast that thebearing roller track segment will maintain a compound annual growth rate above 5% through 2034, driven by the worldwide rollout of smart warehouses, infrastructure investment and the push for longer maintenance intervals in heavy-duty equipment.

Bearing roller track, also known as track roller bearings, are specialized rolling components with thick outer rings and cylindrical roller elements that run directly on hardened roller tracks. Unlike conventional rotary bearings, this bearing family is engineered to guide linear or curved motion while sustaining heavy radial loads, shock impacts and continuous cyclic operation. Typical configurations include stud-type and yoke-type track rollers, widely deployed on automated storage retrieval systems, baggage handling lines, construction vehicle undercarriages, packaging machinery and industrial robot linear axes. The quality of the roller track surface directly determines the bearing’s service life, friction performance and resistance to wear and indentation under dynamic loads. Even minor defects on the track can trigger premature roller fatigue, noise and unplanned downtime for production lines.

Bearing Roller Track Type

Track roller bearings are also called Cam Followers / Support Rollers

1. Main Two Big Categories

Stud-type Track Roller (Cam Follower)
- With integrated threaded stud for cantilever mounting
- Sub-types: Concentric stud track roller, Eccentric stud track roller
- Common series: KR, KRV, CF, CRSB, GCR
Yoke-type Track Roller (Support Roller)
- Mounted onto a shaft inside yoke bracket, no built-in stud
- Common series: NATR, NATV, NUTR, NNTR, STO, RSTO, NA22, RNA22

2. By Roller Structure

Needle roller track roller (most common)
Full complement needle roller track roller (no cage, more rollers, higher load)
Caged needle roller track roller (with retainer cage, higher speed)
Full complement cylindrical roller track roller (NUTR / NNTR series, heavy duty)
Ball type track roller (thick outer ring ball track roller, light-medium load)

3. By Outer Ring Profile

Cylindrical outer ring track roller (flat outer surface)
Crowned / Spherical outer ring track roller (barrel-shaped outer ring, self-aligning)
V-groove track roller / V-guide roller
W-groove / Double-V groove track roller
U-groove track roller
