Cylindrical roller bearing 12310 12310KM Large and medium motor, Rolling stock, Main axletree of machine, Gas engine, Generator, Gear box, Steel rolling machine, Vibrating screen, Transport and lifting apparatus, etc.  Cylindrical roller and race for line contact bearing.Load capacity is big, mainly bear radial load.Roller and ring guard friction small, suitable for high speed rotation.May according to the ring presence of guard, NU, NJ, NUP, N, NF, such as single row cylindrical roller bearings, double row cylindrical roller bearing and NNU, NN and other.The bearing inner ring and outer ring is separable structure. No guard of cylindrical roller bearing inner ring or outer ring, internal ring and outer ring can be to relative axial movement, so can be used as free end bearing.The one side of the inner ring and outer ring with double guard, on the other side of the ring has a single guard cylindrical roller bearing, can withstand a certain degree of axial load in one direction.General use of stamping steel cage, cage or copper alloy car system entities.But there are also part of the use of polyamide forming keep frame. 1.We are a manufacturer producing high quality bearings with competitive prices, More than ten years of experience in product , More than 5 years of experience in foreign trade export; 2.The Most advanced machinery and a strict quality control team . 3.On-time delivery service. 4.Accept non-standard production according to customers’ requirement. 5.High level of performance, quality, of all equipment and service. 6.Promptness in technical support pre- and after sales. 7.Do OEM for our customers.
