Roller bearing is a mechanical equipment component of rolling bearings, which uses rollers as rolling elements to achieve rotational support. It has the characteristics of small starting torque and high rotational accuracy. According to its structural type, it can be divided into self-aligning roller bearings, thrust self-aligning roller bearings, tapered roller bearings, cylindrical roller bearings, etc. . This bearing is suitable for withstanding different radial and axial force loads, and its linear contact structure makes it more advantageous in high load scenarios
The type of use should be determined based on the direction of the load: deep groove ball bearings or cylindrical roller bearings are preferred for pure radial loads, and thrust roller bearings or tapered roller bearings are suitable for larger axial loads. High speed working conditions should prioritize the use of ball bearings or needle roller bearings with higher dn values. When the shaft stiffness is insufficient, the use of deflection sensitive roller bearings should be avoided. Lubrication methods are divided into two categories based on DN values: oil lubrication and grease lubrication. The specific boundary values are determined through corresponding charts
