NSK's thrust roller bearings include products using cylindrical rollers and products using spherical rollers. Although this type of bearing can only bear axial loads, it is suitable for heavy loads and has high shaft rigidity. Among them, the thrust spherical roller bearing has a bulge in the middle of the roller and has the function of self-aligning. Therefore, this kind of bearing is not affected by installation errors and shaft deflection. The cage of the standard configuration is a machined brass product; the E-type product uses a stamping cage, which has the characteristics of large load capacity. NSK thrust cylindrical roller bearings use cylindrical roller thrust bearings, which can only bear axial loads, are suitable for high-load applications, and have high axial rigidity. Copper alloy car cage is used. NSK thrust spherical roller bearings use spherical roller thrust bearings, which are self-aligning. Unaffected by installation errors, shaft deflection. In addition to the conventional type, there is an E type that is designed for high loads and uses a stamped cage. (The mark E is marked at the end of the nominal code). For transverse shafts and high-speed rotation, it is recommended to use bearings with copper alloy machined cages. Please contact NSK for details. There are many parts where the lubricant is not easy to lubricate, such as the sliding contact surface between the roller head and the inner ring rib, and between the cage and the guide bush. Therefore, oil lubrication is used even for low-speed rotation. The traditional cage is a copper alloy car cage.
