Winter Slewing Bearing Use And Maintenance Guide

Entering January, most of China has entered winter, in the cold environment, the normal operation and maintenance of the slewing bearing faces many challenges. Understanding and following the precautions for the use and maintenance of slewing bearings in winter is crucial to prolonging their service life and ensuring the stable operation of the equipment.

Low temperature will make the lubricant viscosity of the slewing bearing increase and the fluidity become poor. This will not only increase the slewing resistance, resulting in equipment startup difficulties, but also affect the lubrication effect, exacerbating wear. Therefore, before the advent of winter, according to the lowest temperature of the environment in which the equipment is located, select the appropriate low-temperature lubricant, its low-temperature fluidity, can quickly reach the lubrication parts at low temperatures, effectively reduce the starting torque, reduce wear and tear, to ensure that the slewing bearing in the cold conditions of smooth operation.

Slewing bearings are more likely to accumulate dust, ice and snow and other impurities in winter. Once these impurities into the raceway and seal, will destroy the lubrication film, cause wear and corrosion, seriously affect the performance and life of the slewing bearing. Daily need to strengthen the cleaning of the equipment, regularly clean the surface of the slewing bearing and the surrounding debris, to prevent the accumulation of snow and ice. For equipment working in harsh environments, consider installing protective devices to reduce the possibility of impurity intrusion, but also to check the integrity of the seals, such as damage to be replaced in a timely manner to ensure good sealing effect.

Under the low temperature environment, the brittleness of the metal parts of the slewing bearing increases, and the ability to withstand the impact load decreases. In the process of starting, braking and running, if the equipment is not operated properly, a large impact force will be generated, which will easily cause cracks or breakage of the raceway, rolling body and other parts of the slewing bearing, bringing serious safety hazards and economic losses. Operators should avoid rough operation such as rapid start, rapid stop and sudden change of direction, follow the operating procedures of the equipment, operate the equipment smoothly, make the slewing bearing accelerate, decelerate and steer smoothly, reduce the damage caused by the impact load, and ensure the safe operation of the equipment.

Regularly checking the mounting bolts of the slewing bearing is also an important part of winter maintenance. Due to the principle of thermal expansion and contraction, the bolts may loosen under low temperature, which will affect the installation precision and overall stability of the slewing bearing, lead to abnormal vibration and noise during the operation of the equipment, further aggravate the wear of the slewing bearing, and may even cause equipment failure. Professional tools should be used regularly to check and tighten the bolt fastening situation, to ensure that the bolt torque meets the requirements, to maintain the stable installation of the slewing bearing, to ensure the normal operation of the equipment.

The maintenance of slewing bearings in winter should not be neglected. Through the reasonable choice of lubricant, strengthen the clean protection, standardized operation and regular inspection of bolts and other measures, can effectively deal with the low temperature environment in winter brought about by a variety of problems, to ensure that the slewing bearing in the cold season is still maintained in good working condition, for the stable operation of the whole equipment to provide a reliable guarantee to prolong its service life, reduce the cost of maintenance of the equipment, improve the efficiency of production, so that the equipment in the winter under the harsh conditions can also be stable and efficient operation, for the production and management activities of enterprises. Can run stably and efficiently, escorting the production and operation activities of the enterprise.
