Track Roller Bearing with U Groove LFR

Track Roller Bearing with U Groove LFR
ISUTAMI LFR track roller bearing with U groove, also known as gothic arch grooved guide wheel bearing, gothic arch grooved roller bearing is made of high quality stainless steel races, retainers, balls and shields. LFR series rail roller bearing is the most widely-use and economy product among the linear motion track rollers, can be adapted to round track. The roller bearing adopts the internal structure design of the precision-polished double row angular contact ball bearing and the thickened hardened outer ring to make the bearing have higher loading capacity. The bearing is made of high quality bearing steel, processed by heat treatment and precision grinding. It is internally filled with high-quality multi-purpose grease; the roller is dust-proof with a metal dust-proof cap or a rubber seal.

Track Roller Bearing with U Groove LFR Features

Characteristics of the guide system that LFR track roller bearing are applied :
1. High allowable speed, low resistance, long service life
For series LFR rollers, the surface profile of the outer ring is designed as the GOTHIC ARCH. When rollers running, there are two contact points with an angle 60 degrees between the roller and track. So the friction resistance is low and the load is in equality, thus avoiding the stresses concentration and edge effect caused by the error from installation and manufacture, making the track system has the characteristics of high speed, low energy consumption, long service life and minimum noise level.
2. Easy installation
As rollers assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, these rollers can get the fitting preload.
3. Smooth running, minimum error and lower noise level
The special processing equipment and testing equipment ensure the accuracy of the shape of the roller. The mature processing technology and strict quality inspection process make all the outer ring of the roller run radially, and the roundness of the working surface is good, which makes the rail system with small error, stable operation,low running noise.
