Specifications
precision POM/PA plastic bearing :under our own registered brand:YWS
Quanlity:ISO9001:2000
Type:Open,ZZ,2RS
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
9.food safe
Over Z2 grade
