by:JNSN     2021-12-22
Suitable for various purposes, various forms and specifications of seated rolling bearings have been serialized. Therefore, when choosing a seated bearing, it is necessary to fully grasp the mechanical structure, operating conditions, environment, etc. and perform a comprehensive analysis on it. The summary of the selection of the form and specification of the seated rolling bearing is shown in Chart 3.2. Table 3.2 Summary of the selection of the form and specification of the seated rolling bearing. Distinguish the required performance. The bearing specification is applicable to the use condition of the bearing box and the fixed seal structure of the shaft. , FL, FS, HA, IP, P, PA, PH, T, TH, TL, TU Eccentric fixing ring NA 1) ○ C, FC, NF, NFL, P, T Dustproof and waterproof stop screw fasteners Triple seal UC-L3UK-L3 ○ C, F, FA, FB, FC, FL, FS, HA, IP, P, PA, PH, T, TH, TL, TU Purification stop screw oil seal SU × FL0, P0 Corrosion-resistant stop screw oil seal + slinger UC-S6Y2.

Therefore, in order to extend the interval of regular maintenance and shorten the maintenance man-hours, it is also very important to select the most suitable rolling bearing with seat according to the purpose and use conditions. In applications where there are vibrations and shocks, improve the life of the bearing and the strength of the bearing box; use stepped shafts in applications with large axial loads; use triple seal products and products with dust caps in dust and muddy environments ; In the use of working under high and low temperature conditions, fully study the material of the oil seal and the grade of the grease.
