Welcometoour shop:
We are rubber belt manufacturer. Our products are as follows: 1: Vehicle synchronous belt: ZBS RPP Za ZB my Yu Mr s8m my Ru ZA, etc. 2: multi wedge belt series: PK PJ PM pH pl 3:V-belt series: cutting V-belt (ZX AX BX CX DX), cloth belt (9.5, A, B, C, D), transmission belt, various coupling belts, agricultural machinery belt 4: Motorcycle Belt 5: Industrial synchronous belt: H, L, MXL, XL, XH, XXH, 14M, 8M, 5M, 3MT20, T5, 3MT20, Automobile synchronous belt adopts international leading raw material formula, manufacturing in strict accordance with technical specifications, with clean appearance, full tooth shape, long service life, low noise, complete specifications and other characteristics. Automotive timing belt characteristics Neoprene synchronous belt: Good heat resistance - can be used in the working environment of 120℃ and below for a long time; Good aging resistance - especially excellent ozone resistance; Good chemical stability: in addition to strong oxidizing acid, resistance to the erosion of general chemicals; Good fire and water resistance; Hydrogenated nitrile rubber belt: Excellent oil resistance -- very low oil swelling resistance, higher oil resistance; Good durability - dynamic performance is better than neoprene synchronous belt, is the first choice of high-grade car transmission belt; Excellent wear resistance -- wear less than neoprene synchronous belt, reduce noise, effectively prolong the service life of synchronous belt; Application of hydrogenated nitrile butadiene rubber in automobile synchronous belt: Modern cars due to energy saving, environmental protection, comfort, safety and other requirements are becoming more and more high, making the whole engine room complex structure, compact, high working temperature, which rubber parts should have high temperature resistance performance. With the improvement of engine lubrication technology, new additives are used in lubricating oil, so higher requirements for oil resistance of rubber parts in engine are put forward. On the other hand, the longer maintenance period, the durability of rubber parts is more and more high requirements. Modern automobile requires rubber parts in a certain oil resistance conditions can be -40℃ ~ +150℃ transmission belt is an important automobile rubber parts, including OHC engine with the timing belt that is synchronous belt, car auxiliary transmission with car V belt and multi wedge belt, as well as the newly developed continuously variable speed mechanism (CTV) with variable speed V belt. Since the first HNBR patent was published in 1975, HNBR has gradually developed into the preferred standard elastomer material for the production of automotive synchronous belts in the world today.
