1, slewing bearings before mounting, first you want to check the mounting surface of the host, and required supports should have sufficient strength, surface machining, surface debris and Burr-free. Cannot be machined to achieve the required flatness, can take a heavy injection of special plastic filler, to guarantee the accuracy of installed flat and used for vibration reduction. Quenching soft band for SKF bearings rings, which are marked on the ferrule end face "s, when installing the soft belt position under non-load or non-regular load area (saizikong is always soft).
2, when you install the wheel bearing, advanced practice and location, cross-tighten the mounting bolts and check the bearing rotation. In order to ensure smooth transmission of the bearing should be installed before the bolt is not tightened to check the gear meshing. Tighten the bolt should have adequate preload, the pre-tightening force of bolt material yield limit of 70%. Mounting bolts should be completed with quenched and tempered flat washer, prohibited the use of spring washers. FAG bearings after installation, operational, in continuous operation in 100 hours should thoroughly check the mounting bolts tightening torque to meet the requirements, repeat the check once every subsequent continuous operation 500 hours.
3, slewing bearings are installed should fill the right amount of grease, and side padding side slewing bearings with grease should be evenly distributed. Wheel bearing in work after a period of time, inevitably will lose a portion of the grease, so the functioning of NSK bearings grease should be added after every interval of 50-100 hours. Working under conditions of high temperature or dust of slewing bearings, add oil-lubrication cycles should be reasonably short. When the machine is stopped when the seal must also fill them with adequate grease.
4, packaging, transport and storage of the slewing bearing: TIMKEN bearings, outer raceway coating required prior to packaging, anti-rust lubricant dual-use grease, then wrapped around the plastic film, compound kraft paper and industrial wrapped around wrapped around the package within the packaging. Outer packaging used for wooden or metal box.
5, INA bearings in the transport process, should be in horizontal position on transport, there should be measures to prevent sliding and prevent vibration, with the secondary support when necessary.
6, the bearings should be in a dry, ventilated place level on flat ground, when stored with chemicals and other corrosive substances should be isolated. If you need multiple sets of bearing overlapping stack, along the circumference should be placed evenly between each set of three or more equal to the height of the wooden blocks, and upper and lower blocks placed in line. Exceed the period of validity will need to continue storing the KOYO bearings, cleaning and rust treatment should be reconsidered.
