Product Description

 

U groove track roller bearing  LFR50/4NPP

1.LFR Series linear guide rail wheel rollers most widely used, economical and practical products that can fit in the cylindrical guide.
2.Contacting wheel and rail for two-point contact, having good contact performance.
3.Roller double row angular contact ball bearing design and thickening of the internal structure of the outer ring, the wheel has a higher carrying capacity.
4.The roller bearing steel with high-quality manufacturing, heat treatment, precision grinding machining, and are filled with long-life high-quality multi-purpose grease.Wheel dust metal dust cover (ZZ) or rubber seals (2RS).Can also provide the wheel with concentric or eccentric pivot, some specifications are also corrosion-resistant stainless steel roller.
Application of LFR series roller guide roller rail systems have the following characteristics:
1.The high-speed, low resistance, long life
The outer surface of the guide roller LFR series designed to Gothic shape, the roller work, wheel and rail forms an angle of 60 degrees for the two-point contact, friction resistance, load evenly to avoid the roller because the installation work and stress concentration caused by a manufacturing error, boundary effect, so that the rail system has a high-speed, low-power, long-life operating characteristics.
2.Easy to install
After the wheel and concentric or eccentric shaft axis, so installation is very easy to adjust the amount of eccentricity of the eccentric rollers can get the fitting preload.
3.Smooth running, low error, low noise operation
Dedicated processing equipment and testing equipment to ensure the accuracy of the shape of the wheel, mature processing technology and strict quality control procedure to make all of the rollers and the outer radial surface roundness good work, so that the rail system at run-time error pole small, smooth operation, low noise operation.
