There are different type of plastic can use to produce bearings ,such as  PP ,POM ,PE ,PEEK .

MKL BEARINGS can produce different type of POM plastic bearing, PP plastic bearing, peek plastic bearing, PVDF plastic bearing for you .

And Below here is Feature for Different Plastic  ：

1.PP Material Features;

1. Good corrosion resistance, resistant to various corrosive media and organic media within a certain temperature and concentration range

2. High mechanical strength and high toughness at liquid nitrogen temperature (- 196 ℃)

3. Good self lubrication and high wear resistance

4. Strong anti adhesion ability

5. Extremely low water absorption and excellent electrical insulation

6. Good resistance to high energy radiation

Main purpose:

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

POM Material Features :

1.High strength, rigidity and toughness.
2.Good impact strength, even at low temperatures.
3.Low moisture absorption (at saturation 0.8%)
4.Outstanding wear resistance and sliding properties.
5.Excellent machinability.
6.Good creep resistance.

PEEK Material Features:

1.Superior strength-to-weight ratio.

2.Creep-resistant.

3.Long-wearing.

4.Withstands very high temperatures about 260°C

5.Radiation- and chemical-resistant.

6. Low water absorption.

For the bearings rings and cage are often use with material PEEK ,the balls are with ceramic such as ZrO2 or Si3N4.
