Cylindrical Roller Bearing Solid Cage
Cylindrical rollers and raceways are line contact bearings. Heavy load capacity, Cylindrical Roller Bearing mainly under radial load. The friction between the rolling body and the ring is small, and is suitable for high-speed rotation. According to the ring has no block edge, can be divided into Nu, NJ, NUP, N, NF and other single row cylindrical roller bearings, and nnu, nn, such as double row cylindrical roller bearings. Cylindrical Roller Bearing The bearing is a separable structure of inner ring and outer ring.
Cylindrical roller bearings without flanges in the inner ring or outer ring, the inner ring and the outer ring can be moved relative to the axial direction, so they can be used as free end bearings. In the inner ring and on one side of the outer ring has a double block, the other side of the ring has a single edge of the cylindrical roller bearings, can withstand a certain degree of axial load. General use of steel stamping cage, Cylindrical Roller Bearing or copper alloy car solid cage. But there is also a part of the use of polyamide forming cages.
The roller and raceway of cylindrical roller bearing are in line contact with the radial load capacity. It is not only suitable for heavy load and impact load, but also for high speed rotation, and improves the lubrication condition of the contact area between the roller end face and the edge, Cylindrical Roller Bearing and improves the performance of the bearing. Bearing human micro-letter is very worthy of attention! Generally applicable to large and medium-sized motors, rolling stock, machine tool spindle, internal combustion engine, Cylindrical Roller Bearing generators, gas turbines, deceleration boxes, rolling mills, vibrating screen and hoisting machinery.
1. Roller and raceway for line contact or repair contact, radial load capacity, applicable to withstand heavy load and impact load.
2. Small friction coefficient, suitable for high-speed, extreme speed close to deep groove ball bearings.
3. N type and Nu type can be axially moved, can be used for free end support because of the change of relative position of shaft and casing caused by thermal expansion or installation error.
4. The machining requirements of shaft or seat hole are higher, Cylindrical Roller Bearing the relative deflection of the outer ring axis of the bearing should be controlled strictly to avoid the concentration of contact stress.
5. Inner ring or outer ring can be separated for easy installation and disassembly.
The cylindrical rollers are in line with the raceway and the radial load capacity is large. It is suitable for heavy load and impact load, and also for high-speed rotation.
The raceway and rolling body of cylindrical roller bearing are in geometrical shape. After the improved design, the new structure design with higher bearing capacity, edge and roller end faces not only improves the axial bearing capacity of the bearing, but also improves the lubrication condition of the contact area between the roller end face and the edge of the baffle, and improves the performance of the bearing.
The material used to manufacture the bearing parts has a great influence on the performance and reliability of the rolling bearing. The general considerations for bearing rings and rolling elements include: hardness related to bearing capacity, fatigue resistance of lubricating conditions under rolling contact and different cleanliness, and dimensional stability. For cages, the friction, strain, and inertia forces must be considered, Cylindrical Roller Bearing and in some cases the chemical effects of certain lubricants, Cylindrical Roller Bearing solvents, coolants and refrigerants. The relative importance of these considerations is also affected by other working parameters, such as corrosion, high temperature, impact load, or the combined effects of these factors。
