In order to improve the actual matching accuracy of bearing installation, it is necessary to use measuring methods and measuring tools that do not deform the bearing to carry out actual precise measurement of the matching surface dimensions of the inner hole and outer circle of the bearing, and the measurement of the inner diameter and outer diameter can be carried out All the items are measured, and the measured data are comprehensively analyzed, based on which, the dimensions of the bearing installation parts of the shaft and the seat hole are precisely matched. When actually measuring the corresponding dimensions and geometric shapes of the shaft and seat hole, it should be carried out under the same temperature conditions as when measuring the bearing.

Composition of combined roller bearings The bearing has a sealed structure and is filled with grease to provide long-term effective lubrication, and the user can avoid lubrication. For the use of harsh working conditions, a channel for replenishing grease can be designed to improve the service life of the bearing. Improper methods can also cause the roller bearing to heat up. Lubrication can reduce the wear of parts during movement, ensure the precision of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication and so on. Composition of combined roller bearings
