High quality bearing steel or stainless steel with the roller, heat treatment, precision grinding processing, high-quality multipurpose grease is filled with long life on the inside.
The LFR series rail roller bearing is the most widely used linear guide roller, economical and practical product, can be adapted to the cylindrical guide rail, smooth running, small error, the movement noise is extremely low, the running speed is very high.
The wheel and rail contact for the two 60 degrees of contact, has good contact performance and running resistance is very small, so as to achieve a long service life.
The outer ring of the roller with internal structure design and thickening of double row angular contact ball bearing, so the roller has higher bearing capacity, bearing eccentric and concentric shaft configuration of the simple
● roller dust using metal shield (KDD) or rubber sealing ring (NPP).
Roller guide rail guide system of LFR series guide roller bearing has the following characteristics:
1 high allowable speed, small resistance, long service life
Ningbo Baichuan bearing production company LFR series guide roller surface of the outer ring is designed into the Gothic shape, so the roller when working, wheel and rail to form an included angle for two 60 degrees of contact, the friction resistance of small, uniform load, avoids roller work due to installation and manufacturing error caused by stress concentration, the boundary effect, job characteristics has the advantages of high speed, low energy consumption, long service life of the rail system.
2 simple and convenient installation
Baichuan guide roller bearing configuration of eccentric shaft and shaft, the installation is convenient, eccentricity of eccentric guide roller bearings can be adjusted by the proper preload.
3 stable running, small error, low running noise
Baichuan bearing special processing equipment and testing equipment to ensure the accuracy of the roller shape, sophisticated processing technology and strict quality inspection process makes the radial roller ring all the beat and the work surface roundness good, the guide rail system errors at run time is minimal, stable operation, low running noise.
