Features:To shock absorptionYou will have two different size for choosing,30x56x14mm/1.2x2.2x0.55in (2pcs),45x86x22mm/1.8x3.3x0.87in (1pc),it is designed to enhance the original car& 039;s shock absorption performance.High strengthHigh strength. Under the rubber hardness, their tearing strength, spalling strength and bearing capacity are much higher than that of the universal rubber. At high hardness, its impact strength and bending strength are much higher than plastic.Wear resistingBearing Washer with size 1.8x3.3x0.87in usePolyurethane own the advantage of wear-resisting. Its wear resistance is very outstanding, generally within the range of 0.01-0.10(cm3)/161km, about 3-5 times that of rubber.Oil resistantOil resistant. Polyurethane elastomer is a of strong polymer compound, and the affinity of non- mineral oil is small, in the fuel oil and mechanical oil is not eroded.Nitrile butadiene rubber is a synthetic rubber, excellent oil resistance,good air tightness,strong adhesion, good aging resistance and other advantages.So,this bearing washer is well oil-resistance.Good low temperature performanceBearing Washer with size 1.8x3.3x0.87in use Polyurethane,g ood resistance to oxygen and ozone. Excellent vibration absorption performance, can be used for vibration reduction and buffering. In the mold manufacturing industry, instead of rubber and spring. It has good low temperature performance.Specifications:Material:Type A:Nitrile butadiene rubber ,B:Polyurethane Color:YellowType(size+pcs) A:(30x56x14mm/1.2x2.2x0.55in ,2pcs),B:(45x86x22mm/1.8x3.3x0.87in ,1pc) Size(about):A:30x56x14mm/1.2x2.2x0.55inch(inner dia+outer dia+height)B:45x86x22mm/1.8x3.3x0.87inch(inner dia+outer dia+height) Package Included:2pcs x Bearing Washer(30x56x14mm/1.2x2.2x0.55in ) Or1pc x Bearing Washer(45x86x22mm/1.8x3.3x0.87in ) Note:1.
