Description Technical Parameters

Hangzhou Ocean Industry Co., Ltd. is one of the leading manufacturers and suppliers of short pitch precision roller chains in China. Welcome to wholesale bulk durable industrial chains and power transmission parts made in China here from our factory. All customized products are with high quality and competitive price.

 

Hangzhou Ocean Industry CO.,Ltd. are professional manufacturer and most of our goods are exported to Europe since 2005.

 

Our special attachments and agricultural chains fit all the harshfarm workingconditions. They are made of wear resistant alloysteel with an anti-corrosioncoating and are compatible withcustom K, F, CA attachments for harvesters,tractors and balers.High tensile strength for longer service life, flexible OEM &ODM for global agricultural machinery wholesalers.

Parameter

Most of our OEM customer send us drawing and we will produce as per their drawing. You can send us drawing by e-mail too then our engineer will offer help. If no drawing, sample also OK. Catalogue also OK.
