5.Structrue of ball bearing

Bearing ringDimension tolerance, geometric tolerances, and surface quality of bearing’ s working surface will influent the operating noise. YCZCO adopts precision CNC machining ,to dimension precision,  geometric tolerances , design drawing , mold making , grinding, cleaning,  assembly ,testing, every link of strict checks. Which is to ensure all our products are tested by our strict criteria.

Ball  The balls evenly with by the cage, often make rolling movementbetween 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. YCZCO’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 YCZCO’s shield, taking the carbon steel material, if necessary,taking stainless steel or other material.

Seal YCZCO adopt 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 differentgrease as request
