One, KOYO bearings use of the environment:

     Depending on the location and conditions of use and environmental conditions select size, precision is guaranteed with suitable bearings KOYO Bearing life and reliability of the premise.

     1, using the site: tapered roller bearings for radial load mainly radial and axial joint load, usually paired with two KOYO bearings, primarily in the automotive front and rear wheels, active bevel gears, differential cruise control, reducers and other transmission parts.

     2, the permissible speed: installed correctly, oiled environment, allowing for the KOYO bearings 0.3-0.5 times the speed limit. Under normal circumstances, at 0.2 times the speed limit is most appropriate.

     3, allowing the tilt angle: Tapered roller bearings are generally not allowed axis relative to shell hole, if inclined, the maximum does not exceed 2 ′.

     4, allowing the temperature: the under normal load, and lubricant temperature performance, and full lubrication conditions, the general KOYO bearings allow the environment of -30 ℃ -150 ℃ temperature.

     Two, KOYO bearing installation:

     KOYO bearings must be installed in a dry, clean environment conditions. Should be carefully checked before installation of shaft and housing mating surface, convex shoulder face, grooves and connecting surface processing quality. All surfaces must be carefully cleaned the mating connector and remove burrs, casting Ex unworked surface must be sand.

     KOYO bearing installation should be preceded with gasoline or kerosene to clean and dry before use, and to ensure good lubrication, KOYO bearings are generally lubricated with grease, oil lubrication can be. Lubricated with grease should be used free of impurities, oxidation, rust, and other superior performance extreme pressure grease. Grease filling is bearing and tank volume of 30% -60%, not too much. With sealing structure of the double row tapered roller bearings and water pump bearing grease has been populated, the user can directly use, can no longer be cleaned.

     KOYO bearings installed, must be applied on the circumference of the ferrule end face equal pressure, push the ferrule may not be a direct hit with a hammer top tool end KOYO bearings, KOYO bearings to avoid injury. Small amount of interference in the case, may be pressed at room temperature with the sleeve KOYO bearing ring face, beating with a hammer sleeve, the sleeve evenly pressed into the ferrule. If large quantities of installation, can be used hydraulic press. Press-fitting, should ensure that outer end face and the housing shoulder, inner end face and the shaft shoulder pressed, does not allow a gap.

     When a large amount of interference, can be heated oil bath or heating sensor KOYO bearings way to install the heating temperature range is 80 ℃ -100 ℃, the maximum can not exceed 120 ℃. Meanwhile, the application of a nut or other suitable fastening means KOYO bearings to prevent widthwise shrinkage after cooling the bearing ring and leaving a gap between the shaft shoulder.

     Single row tapered roller bearings installed last clearance adjustment should be carried out. Clearance values ​​should be based on the use of different conditions and the amount of interference with the size of specifically identified. Necessary, should be tested to determine. Double row tapered roller bearings and pump shaft KOYO bearings has been adjusted at the factory clearance, installation without further adjustment.

     KOYO bearings rotation test should be carried out after installation, first KOYO bearings for rotary axes or boxes, without exception, then in power for no-load, low speed, then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, should stop and check. Normal operation test before delivery.

     Three, KOYO bearing removal:

     KOYO bearings Remove the rear intends to continue to use, you should use the appropriate removal tool. Removing the interference fit of the ring, only to increase tension on the ring will never allow pass through the rolling dismounting force, otherwise the rolling elements and raceways will be crushed.
