The silent chain is constructed using metal links held in place by cylindrical pins. This type of chain is featured in the Ford engine developing the ILSAC GF-6 chain wear test.

It is a standard design with many advantages:

  • Simplicity
  • Lower cost
  • Low chain noise

The roller chain is a more complex system designed to reduce friction, in which link pins are reinforced by roller support (or bushing) that accommodates freely rotating steel rollers. However, this type has several disadvantages:

  • Expensive to manufacture
  • Rapid wear if particles become trapped
  • Significant chain noise

An automobile engine’s timing chain system is used to adjust the movement timing of each component to operate the “intake” process correctly → compression → combustion→ engine “exhaust.”
HZPT automotive engine timing chain system has won a high reputation for meeting the stringent requirements of high-power, compact and high-performance engines, such as excellent wear resistance, fatigue strength, and quietness. In particular, for the 6.35mm pitch silent chain and diesel engine roller chain that is first used in small car engines worldwide, we lead the global auto engine chain market with our unique surface treatment technology.

 Application of Silent Timing Chains 

With the development of the automobile industry, the timing chain of the hzpt automobile engine continues to progress. It has excellent wear resistance, fatigue strength, quietness, and impact toughness, and meets some requirements of today’s high-output, compact, high-performance engines. It has high reliability.
In particular, our 6.35mm pitch automobile engine silent chain has been used in automobiles for the first time worldwide and has been using our unique surface treatment technology.

Related Sprockets and Chains

Sprockets fit our entire conveyor chain range.

The drive chain and the conveying chain are driven by sprockets. The uniform distribution of power depends on the precise transmission between the sprocket teeth and the chain rollers or bushes.

Because sprockets significantly impact the chain’s life, all challenging sprockets (from casting to precision mechanical cutting) are manufactured according to strict tolerances and quality control. We also recommend that all customers replace the sprocket when replacing the chain to maximize the chain life.

Chain factory

Hzpt was founded in 1972. It is 1 of the earliest and most competitive manufacturers in the domestic chain industry and metallurgical manufacturing of steel chains. It mainly produces chains, sprockets, couplings, non-standard complete sets of equipment, dummy ingot chains, non-ferrous casting, and copper product processing. The coverage rate of chain varieties and specifications ranks among the top in China. It is a large-scale machinery manufacturer integrating design, development, production, and sales. It has passed ISO9001:2008 quality management system certification and ISO14001:2004 environmental management system certification.
