61804 6804 POM Plastic Deep Groove Ball Bearing

61804 and 6804 POM plastic deep groove ball bearings are manufactured from high-strength POM (polyoxymethylene) material, offering excellent wear resistance, chemical corrosion resistance, and low friction characteristics.

Technical parameter:

POM plastic bearings, PP plastic bearings:

POM and PP materials have good mechanical strength and wear resistance, suitable for the production of relatively precise plastic bearings, the working temperature from -60℃ to 100℃, high surface strength and smooth, basically no tension, its good self-lubrication performance and low friction coefficient, on the basis of maintaining the traditional advantages of plastic bearings, can be applied to precision and high speed operation. Among them, POM plastic bearings are the most widely used in all plastic bearings, generally the inner and outer ring materials are POM or PP, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The ball is a glass ball, stainless steel ball or ceramic ball, which performs well in alkaline environment but is not suitable for operation in acidic corrosion environment.

Features:

1. High rigidity, high hardness, even at low temperature, high impact strength;

2. Excellent elasticity, good creep resistance;

3. High heat stability and very good dimensional stability;

4. Good sliding performance, wear resistance;

5. Physiological inertia, suitable for contact with food.

6. Not resistant to strong acids and strong oxidants, poor adhesion to paint.
