▼ Description and Features of LV/RV V Groove Track Roller
• LV Series bearings can be widely used in the cylindrical track or " V " profile track with an angle of 120 degrees.Different from the series LFR bearings, series LV bearings are more adaptable to the different track sizes. Each type can be applied with a larger range of track diameters.They are widely used for the heavy-duty track, mobile equipment wire straightening machine and so on.
• Bearings take the internal structure design of double row angular contact ball bearings and have a thick-walled outerring, so the bearings 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.
• The bearings have an undercut on its bottom of groove on the outer ring. If the application disallow this undercut,we can meet customer's technical requirement. Also can accept the bearings with various angle of " V "profile.
▼Characteristics of Guide System that V Groove Track Roller are applied
• Low resistance, long service life, widely-use
The roughness of the " V ", profile surface can be reached to Ra0.32 processed by precision grinding. The bearings have good parallelism between the " V " profile groove and the mounting planes of inner ring relatively. When bearings working, the stresses between the bearing and cylindrical track is in good distribution and the friction resistance is low.
• 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.
