The 20BSS-1 Simplex Short Pitch Stainless Steel Roller Chain is a mechanical marvel that is widely used in diverse industries. As an essential part of any mechanical transmission system, it carries the duty of transferring power and sustaining loads. With its unique structure, material properties, and working principles, it finds its application in areas where strength, durability, and resistance to environmental factors are required.
The 20BSS-1 Simplex Short Pitch Stainless Steel Roller Chain comprises three main components:
Chain plates serve as the fundamental structure of the roller chain. They come in two types - inner and outer chain plates, which are interconnected via a pin.
The roller, the primary load-bearing component of the chain, consists of a roller body and a roller shaft. The roller body cooperates with the lug of the inner and outer chain plates, while the roller shaft works in conjunction with the pin of the chain plate.
The pin serves as the connecting element of the roller chain, attaching the chain plates and roller together.

Our stainless steel chain is crafted from advanced materials that perform exceptionally well in acidic and alkaline environments, direct contact with food, and at extreme temperatures (-40??C to +400 ??C) where corrosion resistance is required. When chemical resistance is crucial, Reynolds stainless steel chains should be selected. They are manufactured from FDA-approved materials and pre-lubricated with USDA H1-approved lubricants.
1. All parts are made of austenitic rust-proof steel
2. All components are surface finish machined to eliminate stress risk factors
3. Lubrication to improve wear performance
4. Tensile strength is about 65% of standard carbon steel chain
The stainless steel roller chain operates by transferring power from the driving wheel to the driven wheel through the chain, ensuring the synchronization of the drive. It exhibits exceptional performance characteristics in power transmission and load-bearing, thereby making it a highly reliable option for various industries.
Short pitch stainless steel roller chains find their application in an array of industries such as food processing, chemical, medical equipment, and more. Their suitability in special environments??like humid and corrosive surroundings??makes them highly demanded in these sectors.

Proper maintenance and care of the stainless steel roller chain involve regular cleaning, lubrication, and routine inspections, thus ensuring the long life and optimal performance of the chain.
Stainless Steel Sprockets for Chains serve as the backbone of a robust and durable chain system. Their seamless interaction with the chains is crucial for smooth and efficient mechanical operations. 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.
