About This Product

Standard roller chain (SBR-PRIME roller chain) numbers and dimensions comply with JIS B 1801. Roller chains made by ZEXUS (formerly SENQCIA) were the first in the world to use seamless SBR (solid bushing and rollers) in 1987. By retaining lubricating oil, it exhibits excellent wear resistance even under harsh conditions and reduces initial elongation. Furthermore, by applying special processing to the pins and link plates, we have succeeded in increasing the maximum allowable load (fatigue strength) by MAX 32%.

■Features

・Increase safety factor and achieve longer life ・One size smaller chain can be selected. ・Achieving high cost performance

■Structure

A roller chain consists of parts such as link plates, pins, bushes, and rollers. Role of parts

■Link plate (outer plate/inner plate)

- Ensures strength as a tensile member when tension is applied to the chain. - Has sufficient fatigue strength and toughness to withstand repeated loads and impact loads during use.

■Pin

・Similar to link plates, it has the strength to act as a tensile member when tension is applied to the chain, as well as the strength to withstand bending, shearing force, and impact force. ・It also has wear resistance because the bush and the outer surface of the pin slide during operation.

■Push

- Has a bearing function with the pin, and has wear resistance on both the inner and outer surfaces. - Has crushing strength that can withstand impact loads.

■Lola

- Impact force is generated when it engages with the sprocket during operation, so it has the impact resistance and crushing force to withstand this force. - The rollers slide and rotate, making them wear-resistant.

■Cotter pin/clip

Used in joints to prevent outer plates from falling off during operation.
