The 28BSS-3 Triplex Short Pitch Stainless Steel Roller Chain is a high-quality, durable chain designed to deliver maximum strength and longevity. It's specifically engineered for use in a variety of mechanical transmission systems, especially those exposed to harsh conditions.
The 28BSS-3 Triplex Short Pitch Stainless Steel Roller Chain comprises three key components: the link plates, rollers, and pins.
The link plates, forming the backbone of the chain, consist of inner and outer plates. These plates are connected using pins, providing the chain with its characteristic flexibility.
The rollers, essential for bearing the load, consist of the roller body and roller pin. The roller body interacts with the protrusions on the inner and outer link plates, while the roller pin co-operates with the pin on the link plate.
Pins are the connecting elements of the stainless steel roller chain, linking the link plates and rollers.

This stainless steel chain is made of advanced materials that excel in acidic and alkaline environments, where direct contact with food is expected. The chain is designed to withstand water exposure and extreme temperatures (-40 ?? C to +400 ?? C), offering superior corrosion resistance. The chain is manufactured from FDA-approved materials and pre-lubricated with USDA H1-approved lubricants. Features include:
Stainless steel roller chains play a pivotal role in mechanical transmission systems. They transfer power and bear loads, offering reliability and performance. The chain's specific design enables it to efficiently transfer energy from a power source to the load, ensuring smooth operation of the machinery.

This stainless steel chain finds applications in various industries, including food processing, chemical, and medical equipment. Its suitability for use in damp and corrosive environments is a significant advantage. The chain's ability to withstand harsh conditions makes it indispensable in numerous applications.
