Imported bearings installed before you use gasoline or kerosene clean and dry before use, and to ensure good lubrication, imported bearings generally use the grease lubrication and oil lubrication can be used. Greased, should be used without the superior performance of impuri ties, anti-oxidation, anti-rust, extreme pressure grease. With sealing structure double row tapered roller bearings and pump shaft bearings filled good grease, the user can be used directly, not cleaning. Grease filling is 30% -60% of the bearings and bearing capacity of the container, not too much.ceramic bearings
Imported bearings installed, you must apply equal pressure on the circumference of the ring face ferrule pressed into not hammer first class tools directly for percussion end bearings, so as not to damage the bearings. Bulk installation, to be used in the hydraulic machine. Press-fitting, should ensure that the shoulder end face of the outer ring end surface of the housing, inner ring end face and pressed by the end face of the shaft shoulder, and allowed gap. At room temperature in the case of the small amount of interference, with a sleeve onto the end face of the bearing rings, with the hammer beating sleeve, through the sleeve will be pressed into the ring balanced.big ball bearing
Oil bath can be used when a large amount of interference, heating or heating sensors the imported bearings way to install, and the heating temperature range of 80 ℃ -100 ℃, the maximum can not exceed 120 ° C. Meanwhile, the application nut or other suitable method of fastening bearings, bearings after cooling in order to prevent shrinkage in the width direction so that a gap is generated between the ferrule and the shaft shoulder
Single row tapered roller bearings installed last clearance adjustment should be carried out. Clearance values ​​should be specifically identified under different conditions of use and the amount of interference with the size. When necessary, should be determined experimentally. Double row tapered roller bearings and pump shaft bearing has been adjusted at the factory, goo d clearance, do not have to re-adjust installation.roller bearing co
The bearing installation: the bearing must be installed in a dry, clean environment under the conditions of. The installation should be carefully examined before the mating surfaces of the shaft and housing, processing quality of the convex surface of the shoulder of the end face of the trench and connected. Mating connector surface must be carefully cleaned and deburred, casting raw surface Ex molding sand.
