SKF bearing installation must be in a dry, clean environment conditions. Before installation should carefully check the shaft and the shell with surface, convex shoulder of end, grooves and connection of surface processing quality. All connected with surface must be careful cleaning and remove burr, casting unprocessed surface must be free green sand.
SKF bearing before installation should use first gasoline or kerosene clean, dry after use, and provide good lubrication, SKF bearing general use of the grease lubrication, also can use oil lubrication. The grease lubrication, should choose without impurities, oxidation, rust and extreme pressure and the superior performance of grease. Grease filling quantity for bearing and bearing capacity box of 30% to 60%, unfavorable and overmuch. Take sealing structure of the double row circular cone roller bearings and water pump shaft bearings has grease filling even good, the user can use directly, and not to do the washing.
SKF bearing when installed, must be in the ring width of circles on the equal pressure, will be pressed into the collar, and shall not use Lang top tool directly knock bearing end, to avoid the damage of bearing. In a surplus quantity is smaller, at room temperatures sleeve bearing pressure with live SKF ring width, with Lang head beat sleeve, through the sleeve will balance pressure into the collar. If large quantities of installation, can be made hydraulic press. Pressure fashionable, shall ensure that outer shell with a shoulder end face, inner ring end face and shaft shoulder end machine pressure, does not allow to have the gap.
When a large surplus quantity, can be made oil bath heating or sensor heating method to install SKF bearing, the heating temperature range for 80 ℃-100 ℃, the highest should not exceed 120 ℃. At the same time, the application of nuts or other appropriate methods to tighten SKF bearing, in order to prevent the bearings after cooling contraction and make the collar width and shaft shoulder produce clearance.
The single row circular cone roller bearings for clearance should be installed last adjustment. Clearance value should be based on the different operating conditions and the interference with the quantity and is specific and affirmatory. When necessary, shall be tested to determine. Double row circular cone roller bearings and water pump shaft bearing out even in SKF has adjust good clearance, when installation, don't have to adjust.
SKF bearing should be rotation experiment after installation, first used in the axis or SKF bearing box, if there is no abnormal, and to power without load, speed, and then depending on the operation situation gradually improve speed and load rotation, and testing noise, vibration and temperature, abnormal, should stop to run and inspection. Running test normal rear can put to use.
