OTOTRI is the bearing brand of Jinan Guanyi Transmission Machinery Co., Ltd., a needle roller bearing manufacturer in Jinan, Shandong, China. We make the full needle bearing family — drawn cup, machined ring, cage assemblies, thrust bearings, cam followers, one-way clutches and inner rings — and we produce parts to customer drawings as well as catalogue items. Our customers are distributors, gearbox rebuilders and equipment manufacturers who need a supplier that reads a drawing, holds a tolerance and ships a batch smaller than a container.
