SKF Bearing Oil Film Lubrication Replacement Steps

Writer: Eric Bearing Limited

The lubrication management of SKF bearing oil film is very important and cannot be ignored. The detailed introduction is as follows: More than half of the main causes of mechanical failure or early wear are related to lubrication technology management.

Improve lubrication management, prevent SKF bearings, gears and other frictional moving parts from being scratched or sintered, prevent and reduce wear, reduce frictional resistance, prevent equipment accidents, and improve equipment production efficiency; save energy, increase energy efficiency, increase Economic benefit is the main task of lubrication management.　　

1. Lubrication management is a professional technical management. Full-time lubrication technical management personnel should be set up to develop a lubrication management system and provide training on lubrication technical knowledge.　　

2. Under the premise of reasonable oil tank capacity, maintain a reasonable oil level of the oil tank, often add lubricating oil to the oil tank, so that the oil in the oil tank is always at a reasonable operating oil level, degas the oil, deposit machine impurities, separate moisture and It is beneficial to reduce the oil temperature in the tank.　　

3. Timing, positioning and extraction of oil samples in the transportation + line, testing and testing from oil odor, color, viscosity change, water content, water separation performance, pollutant type and content, anti-foam performance, etc. When the water content in the oil entering the lubrication point exceeds 0.1%, the mechanical wear increases sharply; the lubrication condition when it exceeds 0.5% will be very dangerous. Make test records.　　

4. Analyze and compare each test record, predict and predict the poor lubrication state, and formulate improvement or prevention measures. The alarm and interlock of the system's oil level, oil quality, oil temperature, and oil pressure control should be safe and reliable to prevent the occurrence of lubrication accidents.

The specific steps of replacing the oil seal when the oil seal at the SKF bearing of the steel wheel walking is leaked are as follows:　　

1. Loosen the four fixing bolts of the vibration motor and remove the vibration motor (no need to disassemble the hose on the motor);　　

2. Loosen the seven fixing bolts on the motor base and remove the motor base;　　

3. Loosen the eight fixing bolts on the support plate and the walking bearing seat and the bolts connecting the support plate and the front frame, and remove the support plate together with the shock absorber and bracket;　　

4. Loosen the eight fixing bolts on the SKF bearing baffle and remove the baffle;　　

5. Find a shim plate with a diameter smaller than the inner ring of the SKF bearing, and lay it on the shaft head of the outer bearing seat;　　

6. Remove the left end cover and place the opposite side on the backing plate, looking for seven M12×70 bolts to fasten the left end cover and the walking bearing housing;　　

7. Tighten the seven bolts in the figure in order in diagonal order, then you can pull out the walking bearing housing and SKF bearing together, after turning the walking bearing housing flat, you can change the model to φ180×220×18 Skeleton oil seal.　　

When installing, pay attention to the disassembly order of each part and install in reverse order. It is necessary to smear more grease on the skeleton oil seal, the drive bearing seat and the outer bearing seat, so as not to damage the oil seal during press-fitting, resulting in another oil leakage failure.   There are large quantity of SKF 22205 E bearings in stock , pls contact us .

The importance of the correct use of lubricants for the operation of SKF bearings

Of course, if the working speed of the bearing is very low and it needs to work in a polluted and humid environment, it is best to fill the SKF bearing seat with grease.

The standard products provided are more than 20,000 types of bearings. In addition to rolling bearings, the group also manufactures linear bearings, sliding bearings, bearing boxes, ball and roller screws, textile machinery parts, retaining rings, machine tools and various precision mechanical parts. Gaining extensive experience in the above fields, he has the indispensable knowledge and expertise to develop, manufacture and apply various advanced engineering products.

The small ones, such as miniature bearings weighing only 0.003 grams, can be as large as 34 tons each. In addition, it also provides a series of bearing maintenance tools, grease and bearing monitoring instruments (bearing heaters, pullers, etc.), so as to make bearing users obtain higher benefits and achieve worry-free operation.

Bearings are precision components, SKF bearings and grease are contaminated and will not run. In addition, at least 14% of all bearings that have been sealed and maintenance-free with grease are only significantly caused by the use of bearings in a small portion of early failures of all bearings. Bearings have excellent manufacturing and design capabilities, and can provide a variety of harsh working conditions sealing solutions.
