U Groove Track roller Bearing with Gothic Arch Grooved Outer Ring for Linear Motion System

Specifications

U Groove Track Roller Bearings
1.Double row angular contact ball bearing
2.The outer ring is with Gothic Arch Groove

• Double Row Angular Contact Ball and Thick-Walled Outer Rings • Allows to Carry Load of Axial and Radial Direction • 52100 or 440C (9Cr18Mo) for corrision-resistance • Normal radial clearance for applications thermal expansion is not a factor • Conforms to ABEC-3 precision within a narrow range of variation • Polyamide 66 cage can reduce friction, vibration, and noise • Available with shields or NBR Seals • Multi-purpose grease used ( Shell Alvania S2 is standard for us )

 

Feature

• Series LFR rollers are the most widely-use and economy product among the linear motion track rollers, and they can suit to the cylindrical track. There are two contact points between the roller andtrack, so the contact function is favorable.

• Rollers feature double row angular contact ball bearing in its internal structure design and a thick-walled outer ring so rollers can accommodate higher loads.

• Rollers are made of high-quality bearing steel, processed by heat treatment and precision grinding, and are filled with a long service life, high-grade and multipurposes grease. Rollers mount the metal shields (suffix ZZ or KDD) or skeleton acrylonitrile-buta-diene copolymers seals (suffix 2RS or NPP) to prevent the dust. can provide the rollers with concentric or eccentric pivot. Some types of the rollers can be made from the corrosion resistant stainless steel.

Characteristics of guide system that LFR5 series roller applied

• High allowance speed, low resistance and long life
For series LFR rollers, the surface profile of the outer ring is designed as the GOTHIC ARCH.When rollers run, there are two contact points with anangle 60 degrees between the roller and track. So the friction resistance is low and the load is in equality thus avoiding the stresses centralization and edge effect caused by the error from installation and manufacturing, making the track system has the characteristics of highspeed, low energy consumption, long service life and minimum noise level.

• Easy installation
As rollers assembled the concentric or eccentric pivot, installation can be made conveniently. To adjust the eccentric one's eccentricity, these rollers can get the fitting preload.

• Smooth running, minimum error and lower noise level
The high precision machinery and complete inspection facilities make accuracy in the profile of roller. Mature manufacturing techniques and critical inspection procedure make all rollers good in the Kea (radial runout) of outer ring and roundness of working surface, so the guide system in motion is smooth running, minimum error and lower running noise level.
