| Classification of plastic bearing materials | ||
| Classification | Introduction | Features |
| POM/PA plastic bearings (precision plastic bearings) | 1. POM and PA materials have good mechanical strength and wear resistance, and are suitable for making relatively precise plastic bearings. 2. Its good self-lubricating performance and low friction coefficient can be applied to precision and high-speed movements on the basis of maintaining the traditional advantages of plastic bearings. Among them, POM plastic bearings are the most widely used of all plastic bearings. 3. Generally, the inner and outer rings are made of POM or PA, the cage is made of glass fiber reinforced nylon 66 (GRPA66-25), and the rolling body is made of glass balls, stainless steel balls or ceramic balls. This kind of bearing performs well in alkaline environment. But not suitable for operation in acidic corrosive environment. | 1. High rigidity, high hardness, high impact strength even at low temperature; 2. Excellent elasticity, good creep resistance 3. High thermal stability and very good dimensional stability; 4. Good sliding performance and wear resistance; 5. Physiologically inert, suitable for contact with food. 6. High thermal stability and very good dimensional stability; |
| HDPE/PP/UPE/(UHMW-PE) plastic bearings (acid and alkali resistant plastic bearings) | 1. HKPE, PP, and UPE materials have been proven to be used in relatively weak acid-base cross environments (30% CUC12 solution and 30% NAOH solution test OK), so they are suitable for most acids/alkali/salt/solutions/oil/ Gas and sea water corrosion environment, with the oil-free self-lubricating properties of ordinary plastic bearings, anti-magnetic and electrical insulation and other properties 2. The mechanical properties are low and easy to deform, so it is not suitable for large loads and high speeds. In comparison, UPE materials have better strength, low friction characteristics and low temperature application characteristics (lowest to -150°C) 3. Generally, the inner and outer rings are made of HDPE, PP or UPE, the cage is made of HDPE, PP or UPE, and the rolling elements are made of glass balls, stainless steel balls or ceramic balls. | 1. Good corrosion resistance, able to withstand various corrosive media and organic media within a certain temperature and concentration range 2. High mechanical strength, can maintain high toughness at liquid nitrogen temperature (-196°C) 3. Good self-lubrication, high wear resistance 4. Strong anti-adhesion ability 5. Very low water absorption, excellent electrical insulation 6. Good resistance to high energy radiation |
| Introduction to PEEK/PI plastic bearings (high temperature resistant plastic bearings) | 1. As an emerging engineering plastic material, PEEK/PI has been proven to be the best in mechanical strength, dimensional stability and high temperature resistance among all known engineering plastics. During the period, the long-term use temperature of PEEK reaches 260°C, and the long-term use temperature of PI reaches 300°C. 2. It has excellent corrosion resistance and can still operate freely in medium-strength acid-base corrosion environments, so it is generally used to make bearings that need to operate precisely in harsh environments 3. The disadvantage is that the cost of the material itself is high. Generally, the inner and outer rings are made of PEEK or PI, the cage is made of PTFE, PEEK or PI, and the rolling elements are made of ZrO2 or Si3N4 ceramic balls. | |
| PTFE/PVDF plastic bearings (corrosion-resistant plastic bearings) | 1. As the most typical varieties of fluoroplastics, PTFE and PVDF have the best corrosion resistance, among which PTFE has the best corrosion resistance among all known engineering plastics, and can be used in all concentrated acids and alkalis , including HF and oleum nitric acid (above 98%), etc. 2. It has good high temperature performance, PTFE is used at 180°C, and PVDF is used at 150°C, but the mechanical stress of PTFE material is extremely low, the dimensional stability is poor, and the temperature deformation is large 3. In comparison, PVDF has better overall performance. Generally, the inner and outer rings are made of PTFE or PVDF, the cage is made of PTFE or PVDF, and the rolling elements are made of glass balls or ceramic balls. | |
For engineering plastic bearings, the type of material used in the bearing is added to the suffix of the plastic bearing model. For example, 6204-2RS means bearing steel 6204 with rubber seal ring, and 6204-2RS PEEK means: PEEK plastic bearing 6204 with rubber seal ring.
