Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing's working surface will influent the operating noise. BY-ROL Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.

Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing's load tolerance and operating capability. We use high precision, small vibration steel ball. It's surface must be strengthened, no bumps scratches, lacerations, pitting and notch.

Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls’ movement and to improve lubrication performance inside the bearing., etc. BY-ROL Bearing’s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.

Shield: BY-ROL Bearing’s shield, taking the carbon steel material, if necessary,taking stainless steel or other material.

Seal: BY-ROL Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.

Grease: The shield and seal were filled with standard grease. We can use different grease as request. High Quality Grease is very crucial in plastic injection process.
