Product Description
91-20 0311/1-07103 flanged bearings can only be transported in horizontal position. Impact should be avoided. Please wear working gloves when operating the swivel ring. Rotary bearings are usually provided with threaded holes in which eyebolts can be fixed. This makes it possible to operate the equipment safely during hoisting. Please observe the relevant laws and regulations when doing this. The slewing bearing must transport three evenly distributed lifting points around it under the condition of connecting lifting equipment. Transportation and installation within the factory can only be in a horizontal position. Transportation must remain in the revolving ring until it is correctly installed. If stacked in a closed room, it can only be stored horizontally and must be a stable middle layer. The anticorrosion coating has a shelf life of about. Packaging for 3 months. Long storage period requires special protection measures. If in doubt, please contact Luoyang East Axis.

Re-lubrication of 1.91-20 0311/1-07103 slewing bearings.
Grease types specified in the delivery drawings shall be used.
Alternative lubricants that can be mixed together can be.
About dealing with each.
Lubricants must be observed.
Pour grease into all cleaned grease fittings one by one.
Rotate the ring until a new layer of grease is formed.
2. Check the mounting bolts. In order to compensate for the possible establishment, it is necessary to retighten the bolts to the specified torque. This should be completed after less than 100 hours of operation, and no external load is applied to the bolted connection. After 700 hours, the operation should be repeated in the hospital or at least once every 6 months. The inspection period should be reduced under special operating conditions. To prevent loose bolts, nuts and washers, replace all bolts, nuts and washers with new washers. 2.2 Check that the wear of the inclined clearance raceway causes the inclined clearance to increase. Therefore, it is necessary to check the working time of tilt gap after 700, or 6 months later. Check the increase of tilt clearance Δ k directly on the swivel ring. For the procedure of checking the increase of tilt clearance, see page 53. The value (m1) determined after installing the slewing bearing is regarded as the basic value and deducted from the measured value (mx). And the difference between mx and m1 shall not be 0.45mm. if the increase of tilt gap δ K is not checked directly, the increase of tilt gap of slewing ring will be converted into each measurement (after installation measurement) and compared to allow δ k. For these two kinds of inspections: if the following conditions occur, shorten the inspection interval to 200 working hours, and the measurement increment of the tilt gap is about. Large allowable increase of 75% tilt clearance. After further increase, reduce the inspection interval tilt gap again (50-100 working hours). If the large allowable increment reaches the tilt gap.
3. Check the seal In the process of maintenance, inspection is also very important. Damaged seals must be replaced. Please contact IMO to obtain the replacement seal, and provide the complete drawing number. The replacement seal can be cut to the required length and installed with simple tools.
