chmotion LFR5201-10-2Z Gothic Arch Track Roller
The chmotion LFR5201-10-2Z is a high-performance gothic arch groove profiled track roller, also identified as LFR5201-10 KDD. Engineered for precision linear motion systems, this double row bearing ensures smooth, consistent, and reliable operation in demanding applications. It is an ideal choice for achieving accurate guidance and movement.
Constructed with robust 52100/100Cr6/GCr15 steel for its rings and balls, and featuring a durable Nylon 66 retainer, the LFR5201-10-2Z is built for longevity. It incorporates shields on both sides, providing essential protection against dust, debris, and other contaminants, thereby extending its service life. Furthermore, this track roller is fully RoHS and REACH compliant, adhering to strict environmental and safety standards.
Key dimensions include a 10mm linear shaft diameter, a 35mm outside diameter, and a 15.9mm width. The LFR5201-10-2Z boasts significant load ratings (Effective dynamic : 8300 N; Effective static : 5000 N) and operates effectively within a wide temperature range of -30ºC to +120ºC (-22ºF to +250ºF), making it a versatile component for various industrial environments.
