5PCS - POM 604 （4x12x4 mm） Bearing Glass Balls Nylon Cage Plastic Ball Bearings

Description

POM/PA Plastic Bearings (Precision Plastic Bearings)
POM and PA material with good mechanical strength and wear resistance. Them syitable for the production of precision plastic bearings. The operating temperature is from -60℃-100℃, with high strength and smooth surface, basically does not appear tension,good self-lubricating properties and low coefficient of friction. On the basis of maintaining the traditional advantages of plastic bearings, they can be applied to the precision and higher speed operation. POM plastic bearings are the most widely used of all palstic bearings. General inside and outside the ball material POM or PA, the cage of glass fiber reinforced nylon 66(GRPA66-25), ball glass ball, stainless steel balls or ceramic balls. Such a bearing physiological inert and suitable for contact with food, alkaline environment, good performance but is not suitable to run in thr acid corrosion and the environment of strong oxidants.

F A Q
1. Why do the bearings I received have shaking?
The clearance of the bearing is related to the play. The default is the standard C0 clearance, which is usually 3-18um. The corresponding principle is shown in the figure below. If you don't need to shake, please choose C2 small clearance bearing. If you have any questions, please contact us before purchasing.
2. What is the accuracy of ABEC-1?
ABEC is the American ANSI standard. The corresponding German DIN standard and international ISO standard are as follows:
