What are Track Rollers with Gothic Arch Groove Type LFR?

Track Rollers with Gothic Arch Groove Type LFR, which translates to "LFR track rollers with Gothic arch grooves," are rolling support components for industrial track systems. They consist of a roller body, built-in bearings, and a sleeve. The rollers have an arc-shaped groove on their outer circumference (resembling a Gothic arch). They belong to the light/medium load (50-500kg) series and are used to roll along tracks, supporting equipment and guiding linear motion.

What are the structural advantages of Track Rollers with Gothic Arch Groove Type LFR?

The core advantage lies in the groove design: Surface contact with the track (rather than the linear contact of conventional rollers) ensures uniform force distribution, reduces localized wear, and extends service life. The symmetrical arch structure fits snugly with the track, providing high guiding precision and preventing deviation and wobbling during operation. The LFR structure, combined with the grooves, ensures stable rolling under medium loads and prevents jamming, ensuring continuous equipment operation.

What equipment are Track Rollers with Gothic Arch Groove Type LFR used for?

They are primarily used in industrial equipment requiring precise guidance: automated warehouse stackers and express delivery carts in logistics; robotic arm rails and electronic placement machine worktable guide rails in automated production lines; and small crane rails and CNC machine tool slide rails for heavy-duty auxiliary equipment, helping these equipment achieve smooth and precise movement.
