What is the design points for bearing with groove in outer race?

The design points of the bearing with groove in outer race for use with the V-rail are as follows:

1. Heat treatment:
The surface of the V-shaped guide rail is hardened and the surface hardness reaches HRC60. The hardness of the V-shaped groove surface of the bearing with groove in outer race is also surface hardened and the hardness reaches HRC60. By ensuring the wear resistance of the component, the whole V-shaped guide can be ensured. The roller linear guide system has a long service life.

2: Precision machining process:
The bearing with groove in outer race is precisely machined to precisely match the V-shaped guide rail to ensure high speed and smooth linear motion.

3. Assembly process:
The bearing with groove in outer race adopts a machining process in which a V-shaped groove is directly machined on the outer ring, and the entire V-shaped bearing has good rigidity. At present, some factories use another assembly process: purchase universal bearings, use interference fit, and put on ferrules; this design, the bearing clearance after assembly is not well controlled; because the ferrule is added later, at high speed and In the case of heavy load, looseness is likely to occur; the spacer is used to prevent axial relative movement between the bearing outer ring and the ferrule, so that it cannot withstand large axial loads. 

4. Sealing and lubrication:
With a precision seal design and high-quality grease, the bearing with groove in outer race are life-free and lubrication-free, which greatly facilitates maintenance and repair.

ZYSL company specializes in bearing with groove in outer race for many years. All raw materials and accessories have been carefully selected to ensure a good user experience.
