round rubber drive belts

Despite their durability, PK belts can wear out, fray, or crack over time due to heat, tension, and environmental factors. A worn belt can lead to slippage, which may cause inadequate power transfer to the alternator and other accessories, leading to electrical failures or battery drain. Consequently, it is vital to inspect the PK belt regularly and replace it when signs of wear become evident, typically every 60,000 to 100,000 miles, depending on the vehicle and driving conditions.

Another remarkable feature of HNBR is its low compression set, which means that it resists permanent deformation when subjected to compressive loads. This is essential for timing belts, as they need to maintain their shape and tension over time to ensure proper functioning of the engine's timing system. With lower compression set values, HNBR timing belts can maintain their performance characteristics longer than those made from conventional materials.
