Japan Oriental Chain Industry Co., Ltd. was established on August 26, 1947, with fixed assets of 1.06695 billion yen. It is a listed joint-stock company. There are currently 139 healthcare workers with an annual output value of 3 billion yen. It is the largest chain manufacturer in Japan. The registered trademark of the product is "OCM" brand. The current president is Takeshi Nishimura. 1、 Transmission chain 1. Precision sleeve roller chain for transmission n Precision sleeve roller chain (JIS: 25,35,41,40,50,60,8010100120140160180200240) n Narrow width chain (42,43, S43, S44, M45, S52, S525, S63) with a width about half of the standard chain width n E series high-strength chain (40E, 50E, 60E, 80E, 100E) n Precision transmission micro chain (S10, 15,25H) n Heavy duty transmission H series chain (HS80, HS100, HS120, HS140, HS160, HS200) and American standards ANSI60H, 80H, 100H, 120H, 140H 160H, 200H series chains. 2. The corrosion-resistant chain is made of stainless steel (SUS304, SUS316, SPH) and can be used in water, acidic and alkaline liquids, and temperatures ranging from -20oC to 400oC. The chain, which has undergone special surface treatment, can be used in saltwater. It has the strength of a steel chain and the corrosion resistance of stainless steel. Nickel alloy chains have good corrosion resistance and are commonly used in food and office machinery. Low temperature resistant chain, suitable for use at temperatures ranging from -30oC to 60oC. 2、 Various standard and non-standard conveyor chains have attachments that can be installed on the inner and outer chain links, as well as on extended pin shafts. They can be installed on one or both sides. The attachment board can be designed in various shapes according to requirements. In addition, there is a lightweight, low-noise, self-lubricating resin roller chain; A roller chain with bearing structure and the ability to bend laterally; Under normal operation of the conveyor chain, the conveyed material can temporarily stay on it with a double speed roller chain, etc. 3、 The towing chain is designed according to the American standard ANSI and is used in low-speed movements (speeds less than 30 meters per minute) such as lifting, balancing, and motion transmission. UAL type: used for static load, low wear conditions, with less than 100 rotations per day. UBL type: used for impact loads, high wear conditions, with a daily rotation frequency of less than 1000 times. 4、 Special chain L cable chain embeds cables into the chain for connecting machinery and power sources for short distance movement. Resin chains are wrapped around steel chain plates to reduce damage to the conveyed material. In addition to standard transmission precision sleeve roller chains, there are also special size series chains for special size chains. A three-dimensional transmission chain is used to drive a three-dimensional (spatial) transmission chain between intersecting shafts. Various types of chain couplings and overload protection chain couplings. The vast majority of the above products use Japanese technology, with self-lubricating sintering rollers, three-dimensional transmission chains, anti-corrosion chains, and other products from Japan Oriental Chain.
