Pom plastic bearings, pp plastic bearings
May 08, 2017

Pom and PA materials have good mechanical strength and abrasion resistance, suitable for the production of more sophisticated plastic bearings, working temperature from-60 ℃ ~100 ℃, high surface strength and smoothness, basically no tension, its good self-lubricating performance and low friction coefficient, in keeping the traditional advantages of plastic bearings, based on the application of precision and high speed operation. The POM plastic bearing is one of the most widely used in all plastic bearings, the general internal and external sphere material adopts POM or PA, the cage adopts fiberglass reinforced nylon 66 (GRPA66-25). Ball is a glass ball, stainless steel ball or ceramic ball, this kind of bearing alkaline performance is good but not suitable in acidic corrosive environment operation. Characteristics:

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

2. Excellent elasticity, good creep resistance.

3. High heat resistance stability and very good dimensional stability;

4. Good sliding performance, wear-resisting;

5. Physiological inertia, suitable for contact with food.

6. Acid and strong oxidant, adhesive paint poor

Main Purpose:

Electromechanical equipment, fitness equipment, food machinery, furniture and decoration building materials

HDPE, pp, UPE materials have proven to be used for relatively weaker acid-base cross environments (30%Cucl2 solution and 30%NaoH Solution test OK) so that most acids/alkali/salt/dissolved/oil/gas and seawater corrosion environments are applied. With general plastic bearings without oil self-lubricating, anti-magnetic insulation and other properties, but the mechanical strength is low, easy to deform, so the type of acid-alkali resistant plastic bearings are not suitable for larger loads and higher rotational speeds, to overcome this kind of acid-alkali resistant plastic bearings shortcomings. In comparison, the use of UPE materials has better strength, low friction characteristics and low-temperature application characteristics (minimum to-150 ℃), generally internal and external coil materials using HDPE, pp or UPE, retaining frame materials using HDPE, pp or UPE, ball for glass ball, stainless steel ball or ceramic ball. Such an acid-alkali bearing comprehensive performance will be greatly improved. Characteristics:

1. Good corrosion resistance, at a certain temperature and concentration range of various corrosive media and organic medium

2. High mechanical strength, cut can be at liquid nitrogen temperature (-196 ℃) to maintain high toughness

3. Good self-lubricating, high abrasion resistance

4. Strong adhesion ability

5. Very low absorbent, excellent electrical insulation

6. Good resistance to high energy radiation performance

Main Purpose:

Electromechanical equipment, fitness equipment, food machinery, furniture and decoration building materials
