Auto Timing Belt for BMW feature:
High flexing capcbility
High transmission capability
CR or HNBR
Meet certificate TS16949

Timing Belt for BMW  produced by Sunco Auto Parts use internationally recognised raw material formulation and are manufactured according to strict technical criteria such as plump tooth profile, long service life, low noise and complete specification.

COROSS Timing Belt for BMW are predominently CR and HNBR timing belts.

CR Timing Belt for BMW have the following advantages:
·Good thermo-tolerance: can be used in the working environment at 120 °C for a long time.
·Good aging-resistance: excellent ozone resistance performance.
·Good chemical stability: can resist corrosion of common chemicals except acid with strong oxidizing property.
·Both flame and water resistance are good.

CR Automotive Timing Belt, which provide comprehensive performance and excellent performance-price ratios, are widely applied to automotive transmission belts, especially those of small-displacement cars.

HNBR Timing Belt for BMW  offer even better performance:
·Extremely good oil-resistance: HNBR has extremely low expansibility and higher oil resistance.
·Good durability: the dynamic characteristics of the HNBR timing belt are better than those of the CR Automotive Timing Belt, so the former naturally is the preferred transmission belt of middle and top-grade automobiles.
·Excellent abrasion performance: the abrasion value of the HNBR timing belt is less than that of the CR Automotive Timing Belt which acts to extend the belts life and reduce noise pollution.

Tooth shapes of COROSS's Timing Belt for BMW are mainly ZA, ZB, MR, RHD, RU, ZLB, RHDN STPD, RS, RPP, ZAS, ZBS, Y, YU8M, S8M, G8M (skewed tooth) and HM.
