Double V Guide Wheel BearingsRV 20/7-10ZZ RV 20/8-10ZZ RV 202/15.38-10ZZ RV 202/15.40-10ZZ RV 201/12-20ZZ RV 202/15.41-20ZZ RV 203/17ZZ Track roller with "V" groove profile on outer ring
Series RV
These tracks have a groove "V" shaped with an included angle of 120°.
This guarantees a smooth, low friction movement and a good distribution of the radial load. The structure of the "V" groove track roller with two rows of steel balls corresponds to the structure of the angular contact bearings. The units are supplied with steel protection shields and steel and rubber contact shields.

Double V Guide Wheel Bearings are the main components of the Linear Motion system, they can be widely used in the industrial robot, cutting machine, motion track, production flow and so on.
• The surface of outer ring is the "W" profile formed by the two "V" with an angle of 90 degrees. The internal or external side face can be matched separately with the concave or protrudable track that both have a "V' profile with the angle of 90 degrees, and also the internal side face can be matched well with the cylindrical track.
• Wheels feature the internal design of double row angular contact ball bearing and a thick-walled outer ring, so the wheels can accommodate higher loads.
• Wheels are made of the high-quality bearing steel, processed by heat treatment and precision grind, and are filled with a long service life, high-grade and multi-purposes grease. Wheels mantle the metal shield or rubber seal (suffix X) to prevent the dust. YITONG also can provide the wheels with the concentric or eccentric bushings, as well as the wheels made from the corrosion resistance stainless steel.
• Characteristics of the guide system that series W wheels are applied :
1. Low resistance, long service life, widely-use
After precision ground, the roughness of working surface of the series W wheels is fine and the angle of 90 degrees is accurate. The wheels have well parallelism between the "W" profile groove and the mount planes of inner ring relatively. When the wheels running, the stresses between the wheel and track is in equality and the friction resistance is low.
2. Easy installation
After wheels assembled the concentric or eccentric bushing, installation can be made convenient. To adjust the eccentric one's eccentricity, the wheels can get
