Bearing special plastic dust cover商品详情
Plastic bearing cover Product Description
Plastic bearing cover unique light weight, easy to install, maintenance-free . With the continuous development of new materials , plastic bearing cover are widely used. For different situations , plastic bearing cover general use PP material.
Polypropylene (PP plastic ) is another fine nylon resin varieties after following the development , it is a high-density, non- linear polymer side chain , high crystallinity will , with excellent overall performance. When uncolored white translucent , waxy ; lighter than polyethylene . Transparency is also better than the polyethylene , rigid than polyethylene . Hardness and heat resistance are superior to low pressure polyethylene, can be used at about 100 degrees. Has good electrical properties and high-frequency insulation from humidity, but the low temperature brittle , aging is not easy to wear . Suitable for production of general machinery parts , corrosion-resistant parts and insulating parts generally inside and outside the ring material PP, cage materials using HDPE, PP, ball glass ball , stainless steel balls or ceramic ball. PP Bearing Features : 1 good corrosion resistance at a certain temperature and concentration ability of various corrosive media and organic medium 2 high mechanical strength , high toughness 3 cut can be maintained at liquid nitrogen temperature (-196 ℃).. good self- lubricating, wear high 4 5 anti-adhesion ability . extremely low water absorption, excellent electrical insulation 6 . good resistance to high energy radiation .
