General steps for maintaining a spherical bearing with a seat

   1) Track and record the position of the TIMKEN bearing in the mill. Timken can provide customers with a card bearing maintenance service record card, which can be used to record the housing number, roll number, frame number, bearing position on the rolling mill, outer ring bearing area and rolling product tonnage and bearing Data such as hours worked. The record card should be updated at any time and is convenient for maintenance personnel to check. The bearing blanks can record bearing measurement data and other test details.
    2) Remove the bearing housing from the roll and remove the bearing from the bearing housing. Whether it is to remove the bearing from the bearing housing or to carry out bearing inspections, special lifting methods and tools are required. Timken can provide customers with lifting tools and special lifting methods.
    3) Clean the TIMKEN bearing. All flaking, water, residual lubricant and any other contaminants that cause severe wear on the bearings should be removed during the cleaning of the bearings. The cleaning method and cleaning agent used to clean the bearings are determined according to the size of the bearing to be cleaned or the number of bearings. Small bearings or a small number of bearings can be used with kerosene, mineral oil or other commercial solvents. For large bearings or a large number of bearings, a neutral oil with a viscosity of 22 cSt (or 100 SUS at 100 °F) at 40 °C can be used in a cleaning tank.
    4) Check TIMKEN bearings, including visual inspections and minor repairs. On the outer surface of the inner ring or the surface of the roller on which the roller can be removed, if a small peeling or skin crack is found, the metal is usually peeled off by a sander and the edge of the peeling surface is polished.
    5) The degree of bearing wear should be checked regularly, and the bearing wear can be evaluated by measuring the bearing clearance;
    6) Inspect and repair the bearing housing as needed;
    7) Put the bearing back into the bearing housing;
    8) Inspect and repair the roll neck as needed;
    9) Mount the bearing housing with the bearing onto the roll.

Use and maintenance of IKO wheel bearings

The vehicle should work within the rated load range. If the overload is severe, it will directly cause the hub bearing to overload, which will cause early failure of the automobile hub bearing, and more serious will cause vehicle failure and personal safety accidents;
It is forbidden to subject the automobile hub bearing to abnormal impact load;
Regularly check the use condition of the hub bearing, pay attention to observe whether there is abnormal noise and partial sharp temperature rise in the bearing part of the hub;
Regular or quantitative filling of lubricating oil or grease as required;
According to the condition of the vehicle, the lubricant should be completely replaced at least every six months, and the wheel bearings of the car should be inspected carefully;
Inspection of the bearing condition of the hub bearing: Clean the wheel bearing under the detachment with kerosene or gasoline, carefully observe whether there is sliding or creeping of the inner and outer cylindrical surfaces of the hub bearing, and whether the inner and outer raceway surfaces of the hub bearing are flaking or pitting. Whether the rolling elements and cages are worn or deformed, etc., according to the comprehensive inspection of the automobile hub bearing, it is judged whether the hub bearings can continue to be used.
