Bearing structure:

Bearing ring Dimension tolerance, geometric tolerances, and surface quality 

of bearing’ s working surface will influently 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 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 ball’ s movement and to improve lubrication performance inside the bearing., etc.

 YCZCO’s cage is commonly made of cold rolling carbon steel. But in the corrotiveness 

environment ,nonparallel or high - speed situation,stainless steel, engineering plastics 

cage can 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 different 

grease as request.
