Plastic linear bearingfeature introduction。In recent years, engineering plastic products have gained wider application with their excellent performance. Engineering plastics have broad application prospects in bearings, and more and more users are welcome to use them. Because engineering plastic bearings have excellent self-lubricating properties, wear resistance, low friction and special seizure resistance, they work well even under poor lubrication conditions, making them ideal for use as bearing materials. Therefore, for the relevant engineering plastic bearing company, the market prospect is very broad, making full use of market opportunities and developing related plastic bearing products.
Plastic linear bearingspecialty：
1. High rigidity, high hardness, high impact resistance even at low temperatures;
2. Excellent elasticity and good creep resistance；
3. High thermal stability and good dimensional stability;
4. Good sliding properties and wear resistance;
5. Physiologically inert, suitable for contact with food;
6. It is not resistant to strong acids and strong oxidants and has poor adhesion to paint.
The main objectives of plastic linear bearings:
Electromechanical equipment, fitness equipment, food machinery, furniture and decorative materials.
HDPE，PP，UPE plastic bearing
HDPE, PP, UPE materials have been found to be used in relatively weak acid-base cross-linking environments (30% Cucl2 solution and 30% NaoH solution, fully tested) and are therefore suitable for most acids/bases/salts/solvents/oils / Gas and sea water corrode the environment. It has the characteristics of self-lubricating and oil-free anti-magnetic insulation of general plastic bearings, but its mechanical strength is low and it is easy to deform. Therefore, these acid-resistant plastic linear bearings are not suitable for large loads and high speeds to overcome the acid resistance.
In contrast, UPE materials have better strength, low friction properties and low temperature (up to -150 ° C) application characteristics. The general materials for the inner and outer rings are HDPE, PP or UPE, and the materials are HDPE, PP or UPE. The ball is a crystal ball, a stainless steel ball or a ceramic ball. The overall performance of this plastic linear bearing will be greatly improved.
