NSK bearings installed:
The NSK bearings must be installed in a dry, clean environment under the conditions. 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.machine bearing
NSK bearings installed before you clean gasoline or kerosene, dried, and ensure good lubrication, NSK Bearings generally lubricated with grease, oil lubrication can be used also. Greased, should be used without the superior performance of impurities, anti-oxidation, anti-rust, extreme pressure grease. Grease filling is 30% -60% of the tank capacity of NSK Bearings NSK Bearings, not too much. Double row tapered roller with a sealing structure NSK bearings and pump shaft with NSK Bearings has filled with good grease, the user can be used directly, not cleaning.
NSK bearings installed, must be applied on the circumference of the ring face equal pressure ferrule pressed into not a direct hit with a hammer first class tool NSK bearing end face so as no t to damage the NSK Bearings. At room temperature in the case of the small amount of interference, with a sleeve onto NSK the end face of the bearing rings, with the hammer beating sleeve, through the sleeve will be pressed into the ring balanced. 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.
Oil bath can be used when a large amount of interference, heating or induction heating NSK Bearings way to install heating temperature range of 80 ℃ -100 ℃, the maximum can not exceed 120 ° C. Meanwhile, Applied nut or other suitable method of fastening the the NSK bearing to prevent NSK bearing cooling after shrinkage in the width direction of the ferrule and the shaft shoulder a gap is generated between the.
Single row tapered roller NSK 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 NSK bearings and pump shaft NSK Bearings has been adjusted at the factory good clearance, do not have to re-adjust the installation.ball roller bearing
Rotation test should be carried out after the installation of NSK bearings for rotating shaft or NSK bearing box first, without exception, will power, no-load, low-speed operation, and then gradually increase depending on the functioning of the rotation speed and load, and detection noise, vibration and temperature rise, abnormal, should stop running and check. Normal operation test before delivery.
NSK Bearings Removal:
NSK bearings removed after intends to continue to use the appropriate removal tool should be used. Removing the interference fit ferrule, only the tension applied to the ferrule, and never allowed to pass through the rolling dismounting force, otherwise the rolling elements and the raceway are bruised.
Use of the environment, NSK Bearings:
Select specifications of size, accuracy based on the use of parts and conditions of use and environmental conditions, with appropriate NSK Bearings guarantee the NSK bearing life and reliability of the premise.
1, use parts: Tapered roller NSK Bearings applies to bear radial load mainly radial and axial joint load, usually use two sets of NSK bearings paired, the main hub in the front and rear wheels of the car, take the initiative to bevel gear differential, transmission parts reducer.double bearing
2, allows speed: install properly oiled environment, allowing for the of NSK Bearings limit speed 0.3-0.5 times. Under normal circumsta nces, the limit of 0.2 times the speed of most appropriate.
3, allows the tilt angle: tapered roller NSK bearings generally does not allow shaft relative to the housing hole tilt, tilt, if any, up to more than 2 .
4, allowing the temperature: under normal load, and lubricant with a high temperature performance, and adequate lubrication under the conditions, generally NSK bearings allows to work at the ambient temperature of -30 ℃ -150 ℃.
