Cylindrical roller bearing series introduces cylindrical roller bearing roller bearing sales hotline spot cylindrical roller bearing manufacturer. 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. According to the ring presence of guard, NU, NJ, NUP, N, NF, such as single bearing, double row bearings and NNU, NN. 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. But there are also part of the use of polyamide forming keep frame.
1. The roller and raceway for the line contact or offline contact, radial bearing capacity big, apply to under heavy load and impact load.
2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.
3. The N type and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.
4. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration.
5. The inner ring or outer ring separable, easy to install and disassemble. . Is mainly suitable for high speed and high speed running, and very durable, need not often maintenance. These bearing small friction coefficient, high limit speed, simple structure, low manufacture cost, easy to achieve high precision manufacturing. Size range and variety in form, used in precision instrument, low noise motors, automobiles, motorcycles and general machinery and other industries, is the most widely used type of bearings in machinery industry. Mainly bear radial load, also can withstand a certain amount of axial load.
Deep groove ball bearing is my company's main products, the selection of its larger radial clearance when the axial bearing capacity increases, under pure radial force when the contact Angle is zero. With the axial force, the contact Angle is greater than zero. Usually use stamping ribbon cage, car solid cage, sometimes also used nylon frame. Main application:
Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery roller bearing series introduces cylindrical roller bearing roller bearing sales hotline spot cylindrical roller bearing manufacturer.
