The 085SS-2/41SS-2 Duplex Short Pitch Stainless Steel Roller Chain is a critical component in mechanical transmission systems. Known for its durability, strength, and resistance to corrosion, it is widely used in various industries for its exceptional performance. This chain's primary purpose is to transmit power efficiently and effectively, making it indispensable in applications like food processing, chemical industries, and medical equipment.
The 04CSS-1/25SS Stainless Steel Chain is composed mainly of three parts: the chain plates, rollers, and pins.
The chain plates, which form the basic structure of the short pitch stainless steel roller chain, are made up of inner and outer plates connected through pins.
The rollers, the main load-bearing components of the chain, consist of a roller body and a roller shaft. The roller body matches the protruding platform of the inner and outer chain plates, and the roller shaft is compatible with the chain plate's pin.
The pins serve as the connectors in the short pitch stainless steel roller chain, linking the chain plates and rollers together.

Our stainless steel chain is made of advanced materials. They perform very well in acidic and alkaline environments where direct contact with food is necessary. Chains will be exposed to water and at extremely high or low temperatures (-40 ?? C to +400 ?? C) where corrosion resistance is required. When chemical resistance is critical, Reynolds stainless steel chains should be selected. It is manufactured from FDA-approved materials and pre-lubricated with USDA H1-approved lubricants. All parts are made of austenitic rust-proof steel, and all components are surface finish machined to eliminate stress risk factors. Lubrication is applied to improve wear performance, and tensile strength is about 65% of standard carbon steel chain.
The stainless steel roller chain functions by transmitting power through the rollers that are attached to the chain plates. It is especially effective in carrying loads and transmitting power due to its solid and reliable structure. The rollers rotate around the pins, allowing the chain to move smoothly and efficiently.
The 04CSS-1/25SS Stainless Steel Chain has a wide range of applications, including food processing, chemical industries, and medical equipment. Its resistance to corrosion makes it well-suited for wet and corrosive environments. Each of these applications is discussed in detail below:


Proper maintenance and care of the short pitch stainless steel roller chain include regular cleaning, lubrication, and inspection. These steps help ensure the chain's longevity and optimal performance.
Stainless Steel Sprockets for Chains serve as the backbone of a robust and durable chain system. The seamless interaction between these sprockets and chains is crucial for smooth and efficient mechanical operations. The corrosion-resistant nature of stainless steel ensures longevity, making it ideal for various applications. The precise engagement of teeth on the sprockets with the links of the chain guarantees reliable power transmission. This symbiotic relationship enhances the overall performance, reducing wear and tear while maintaining a high level of efficiency. In industries where reliability is paramount, the combination of stainless steel sprockets and chains becomes indispensable for seamless functionality. In addition to stainless steel chains, we also offer high-quality stainless steel sprockets for sale.
