High-performance series with improved wear life.
This is a notice from Oriental Chain Industry Co., Ltd. regarding the "Transmission Products OCM Roller Chain LR Series."
High-performance series with improved wear life.
This is a notice from Oriental Chain Industry Co., Ltd. regarding the "Transmission Products OCM Roller Chain IX Series."
A simple structure consisting of two sprockets and two rows of roller chains, with rich flexibility in coupling.
We have changed the material of the coupling case from the conventional nylon type to an aluminum alloy type.
Long hours of operation without lubrication are possible! Roller chain using sintered alloy impregnated with special lubricating oil in the bush.
The "Selube Chain" uses a sintered alloy that is impregnated with a special lubricant in the bush, allowing for long hours of operation without oil due to its self-lubricating properties. In terms of oil-free operation, wear elongation has significantly improved compared to standard roller chains. It is suitable for use in environments that require cleanliness and dislike dirt, as well as in locations where lubrication is difficult. 【Standard Specifications】 ■ Plates: Phosphate coating treatment ■ Pins: Nickel plating treatment For strength considerations, the inner plates are thicker, but it is compatible with standard roller chains and can use OCM standard sprockets directly. *For more details, please download the catalog or contact us.

The world's smallest class roller chain with a pitch of 3.1775mm!
The "OCM Mini Chain" is a roller chain for transmission in the smallest class. The chain pitch is 3.175, developed to be even smaller. It is mainly used in medical endoscopes, and we take pride in it being our unique technology. [Features] - World’s smallest class - Developed with an even smaller pitch *For more details, please refer to the catalog or feel free to contact us.
NEW! Highly self-repairing and resistant to rust! A roller chain with excellent corrosion resistance even in harsh environments!
■: Roller chains with excellent corrosion resistance even in harsh environments By applying a special three-layer coating to standard roller chains, we have achieved a significant increase in durability compared to traditionally surface-treated chains! ■: There is no reduction in strength, so the tensile height and allowable tension are the same as standard roller chains ■: Even if scratches or cracks occur, the special coating covers the damage and delays the onset of rust.
Features of transmission, installation and removal, etc. are published! Introduction of various chains.
This catalog introduces the "RK Roller Chain" manufactured by RK Japan Co., Ltd. It includes information on "Features of RK Roller Chain Transmission," "Handling of Roller Chains and Sprockets," and "Selection of Roller Chains for Transmission." Additionally, you can find product information such as "RK25" and "25 Sprocket," as well as formulas for selection and lubrication methods. [Contents (Partial)] ■ Features of RK Roller Chain Transmission ■ Handling of Roller Chains and Sprockets ■ Structure of RK Roller Chain ■ Dimensions and Specifications Table of RK Roller Chain ■ RK Standard Roller Chains and Sprockets - RK25 to RK240 *For more details, please refer to the PDF document or feel free to contact us.
A new long-life cell chain has been added! It is now possible to use it for a wider variety of applications than ever before!
The oil-free roller chain "Selube Chain" uses a sintered alloy infused with special lubricating oil in the bushings, allowing for long hours of operation without lubrication due to its self-lubricating properties. The ND Selube Chain, which has undergone special treatment, offers more than four times the wear resistance at room temperature compared to the Selube Chain. It is ideal for extending the replacement period of the Selube Chain even further.
Significantly improved corrosion resistance compared to conventional surface treatment chains! Exhibits excellent performance in environments exposed to rainwater and seawater!!
The environmentally resistant roller chain "TLH Series" has significantly improved corrosion resistance compared to conventional surface-treated chains by applying a special three-layer coating to each component of the roller chain. It demonstrates excellent functionality in environments exposed to rainwater and seawater. Even after prolonged operation, when subjected to salt spray testing, the chain exhibits high corrosion resistance due to the strong adhesion and self-repairing interactions. After 1000 hours of salt spray testing on chains that have been in operation for a long time, there is no occurrence of red rust on the high corrosion-resistant roller chain. *Please note that corrosion resistance may decrease depending on the usage environment. No harmful substances such as hexavalent chromium, lead, cadmium, or mercury are used, making it environmentally friendly.
We are confident in our low prices! With thorough cost reduction and an efficient management system, we provide products that offer astonishing value for money!
The surface of the steel is hardened to increase its hardness while maintaining the original state internally, resulting in excellent flexibility and a long lifespan that takes advantage of these properties. It is recommended for use in areas where wear resistance and impact resistance, such as drive shafts, are required. 【Features】 ■ The surface of the steel is hardened to increase hardness while the interior remains in its original state. ■ Excellent flexibility. ■ Suitable for environments requiring durability and corrosion resistance. ■ Achieves long lifespan. ■ Recommended for use in high-temperature environments and places exposed to humidity or water. *For more details, please refer to the PDF document or feel free to contact us.
