precision POM/PA plastic bearing

Specifications

precision POM/PA plastic bearing   : 

1.POM can be used in temperatureranging from -60 degrees +100 degrees ,the high surface strength is only surpassed by a few materials.POM shows good sliding roperties and high resistance to wear and tear because of the high strength and smooth  surface,there  is a very low risk of te stress cracks.POM(copolymere) exhibits a high thermal stability and  a high resistance to chemical(high resistance to hydrolysis).

advantage:                                                                                                         disadvantages:

1.high strength                                                                                                  1.not resistant to high-concentratedacids

2.high rigidity                                                                                                      2.difficult to glue and paint

3.high thermal stability

4.good eletrical insulation properties

5.very good sliding properties

6.high resistance to solvents

7.very high resistance to stress cracks

8.UV-resistant(only black)

2.PA(Nylon) the high-crystalline polyamide ranks as an engineer plastic.PA shows a high thermostability (temperature resistant from -40degree to approx +100degree) also hig sfiffness, hardness and toughness are some of its main characteristics.due to the fact ,that the good mechanical will be achieved only after conditioning.this maerial must conditioned again after an annealing, in addition.this conditining occurs with a longer storage in air automatically,

advantage:                                                                                                         disadvantage:

1.high strength and stiffness                                                                          1.dimension stability,electrical and mechani cal

2.high impact strength                                                                                      perties may becone affected by absorbing moisture 3.highheat deflection temperature                                                                      or water

4. good at dampening

5.good abrasion resistance

6.low cofeeicient of friction

7.good chemical stability against organic

lvents and fuels
