▼ Description and Features of SR Track Roller
• The function of series SG rollers are same as the series LFR rollers. But they are mainly used in the flat track and in the condition required compact structure. After rollers are installed to the slider, the shaft will be not or seldom over the roller's side planes. 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.
• Bearings are made of the high-quality bearing steel, processed by heat treatment and precision grinding, and are filled with a long service life, high-grade and multipurposes grease. Bearings take the metal shields 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 series SG track roller are applied
• High allowance speed, low resistance and long life
For series SG 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
After bearing assembled the concentric or eccentric pivot, installation will be convenient. To adjust the eccentric one's eccentricity, the bearing 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.
