During early 1980’s, in the beginning of “Reform and Open “, under requirements of Baosteel and Wuhan steel etc., we started to produce full complement cylindrical roller bearings to replace their imported bearings for their imported equipments. And now we are manufacturing all SL series including SL01(NNC), SL02(NNCL), SL(NNF), SL05, SL06, SL11, SL12, SL14, SL15, SL18(NCF), RSL18, SL19(with radial self-locking), LSL, ZSL etc. As well as track roller bearings like NUTR, NNUPR etc. within OD of 800mm..

Our quality bearings are applied in the manufacturing companies of hoisting machinery ,shipyard, seaport machinery , steel machinery , speed reducer etc .and our quality products also being exported to overseas markets including Germany , U.K., Spain Netherlands , U.S.A., Canada , U.A.E .,Saudi Arabia ,Iraq, Syria , India etc..

SL bearing

We are specialized in researching and making SL series Cylindrical Roller Bearing for 15 years with the help of our European customers. This type of bearing is with full complement cylindrical rollers which generally used in crane rope sheaves and running wheels where heavy, impact load is involved.
Now we can make two types of SL series bearing including open type and shielded type (PP). In structure, it can be single-row, double-row, snap groove on outer ring, etc. The bore diameter can be from 50mm to 300mm.

We can also make triple-row and four-row type or other special full complement cylindrical roller bearings according to the technical drawings from the customer.
