Non-standard plastic bearing

Specifications

  Non-standard plastic bearing : 

1. Plastic bearing applicance : 

1) These plastic bearing are widely used in mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorating materials . (Home appliances, electric tools, fitness equipment, motors, medical devices, motorbikes, textile machines) 

2) The plastic bearing also used in equipment, instrument, building machinery, rolling stock agricultural machinery and various specialized machineries.

2.Plastic Bearing Specification information;

1> POM and PA material with good mechanical strength and wear resistance, suitable for the production of precision plastic bearings, working temperature from -60 °C to 100 °C, high strength and smooth surface, basically does not appear tension. 

2> POM and PA material with good self-lubricating properties and low coefficient of friction can be applied on the basis of maintaining the traditional advantages of plastic bearings, precision and higher speed operation. 

3> POM plastic bearing is the most widely used of all plastics bearing a kind of general internal and external ball materials with POM or PA, to maintain the frame of glass fiber reinforced nylon 66 (GRPA66-25). 

4> POM plastic bearing ball glass ball, stainless steel balls or ceramic balls, such bearing alkaline environment, but not suitable for acidic corrosion 

Environments. 

 5> POM plastic bearings features: 

(1). Rigid, high hardness, even at low temperatures, high impact strength; 

(2). Excellent flexibility, creep resistance; 

(3) high thermal stability and very good dimensional stability; 

(4). Sliding performance, wear; 

(5). Physiologically inert, suitable for contact with food. 

(6). Even in strong acid and strong oxidizing agents, bonding paint 

6>  POM plastic bearings main purposes: 

Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorating materials 

1.HDPE (high density polyethylene)

there two polyolefins offer resistance to almost all acids and bases,detergents and hot water,PE has good insulation properties and is easy to weld,the operating of the HDPE is from -50 to +90 degree

advantage:                                                                                                         disadvantages:

1.light weight                                                                                                     ft surface

2.high toughness                                                                                             2.HF welding not recommended

3.high elongation                                                                                             3.difficult to varnish and glue

4.very good electrical and dielectric properties                                          4.not wather resistant

5.very low water absorption

6.high chemical resitance

7.good protection against stress cracking

8.food safe 

2.PE-UHMW:it's muy buenas propiedades de deslizamiento than HDPE

3.PP (polypropylene ) shows a high mechanical strength,ensile strength, but a low notched impact strength .pp resists stress cracking and it is easy to weld at minus temperatures it can get brittle.the chemical and electrical properties are very good,the temperature ranges between +5  degree and+ 100 degree.

advantage:                                                                                                         disadvantages:

1.low density                                                                                                   1.low oxidation resistance

2.good heat resistance                                                                                 2.low abrasion resistance

3.high tensile strength highsurface strength                                            3.HF-welding not possible

4.high chemical resistance                                                                          4.difficult to varnish and glue

5.food safe
