FRR32 EI V-type guide roller bearing is a heavy-duty cam follower designed for precise linear motion and angular guidance.

It features an integrated 90° V-groove outer race, double-row rolling elements for high radial and axial load capacity, and excellent anti-overturning performance.

Equipped with contact seals for dust and moisture protection, it is widely used in automated lines, robot travel axes, logistics equipment, and precision conveying systems.

The FR22EI is a high-performance stud‑type track roller and cam follower engineered for precision linear motion and heavy‑duty operational conditions. Its rolling elements are optimized to deliver exceptional low-friction performance while maintaining extremely high dimensional and running accuracy, ensuring smooth and stable operation even under demanding working environments.

As a track roller widely used in industrial automation and machinery, the FR22EI is an ideal choice for conveyor systems, linear guide assemblies, cam mechanisms, packaging machinery, material handling equipment, and other applications requiring smooth rolling, high load-bearing capacity, and consistent precision.

The differences indicated by the letters are: EI denotes a press-fit bearing, EU denotes an integral bearing, FR denotes concentric, and FRR denotes eccentric.

A roller box (also known as a roller housing or wheel box) is a core component in V-type roller guide rail systems that integrates and secures rollers, bearings, axles, and other parts. It serves as a load-bearing and transmission structure, enabling the roller guide rail to stably move along the track while protecting internal components from environmental damage (e.g., dust, oil stains).
