Slewing bearings are the most commonly used bearings in the construction machinery and construction machinery industries. According to the structure, it can be divided into: single-row four-point contact ball slewing bearing, double-row four-point contact ball slewing bearing, double-row angular contact thrust ball slewing bearing, crossed cylindrical roller slewing bearing and three-row cylindrical roller slewing bearing, etc. Bearings of different structures can be divided into different types such as toothless type, external gear type and internal gear type according to whether they have teeth or not. Different structures, different sizes and different applications require different materials for slewing bearings.

Under normal circumstances, the slewing bearing ring is selected from 50Mn, but sometimes 42CrMo is selected to meet the needs of the host in special applications. The rolling elements generally use GCr15SiMn. The type of retainer has different structural types such as integral type, segment type, isolation block type, etc. Sealing ring material: oil-resistant rubber, fluorine-containing rubber, oil-resistant nitrile rubber, etc.

No matter what kind of raw material you choose, you must fully consider the actual application and load of the bearing. Luoyang FV specializes in the production of various types of slewing bearings, welcome to contact us.

The structure of slewing bearing: commonly used are single-row ball slewing bearing, double-row ball slewing bearing, single-row cross-roller slewing bearing, three-row roller slewing bearing, ball-roller hybrid slewing bearing and other different structures, slewing bearing rolling body is made of fully hardened carbon-chromium bearing steel GCr15 or GCr15SiMn steel. These slewing bearings are divided into gearless, external and internal gear structures according to whether they have teeth and the distribution of teeth. The slewing bearing rings are made of hardened steel on the outside.

Slewing bearings of different structures have different installation methods.
Installation of slewing bearing: Correctly place the inner ring and outer ring, first lay the outer ring flat on the workbench, put the lower half ring and try to make the outer ring raceway correspond to the inner ring raceway, correctly place the rollers and isolate piece. Place the optional cylindrical roller and spacer block along this track. When placing adjacent cylindrical rollers, their axes are perpendicular to each other, and the two rollers are separated by an spacer block. Special application occasions require the use of special ball or roller isolation blocks, such as copper, aluminum and other high temperature resistant isolation blocks, generally installed on the bearings on the horizontal axis or continuously tumbling generators and those with high requirements on positioning and reliability. The slewing bearing used in the occasion.

Slewing bearings are very important construction machinery parts. Slewing bearings are a simple yet complex category. Structurally, there are mainly slewing ring bearing with internal teeth, external teeth, and no teeth. In terms of internal structure, it is divided into single-row, double-row, and three-row ball and roller slewing bearings. Because the slewing bearing is widely used, once there is a problem, it must be repaired in time. Today Luoyang FV provides three simple repair methods, I hope these methods are useful to you.

1. Record the appearance of the slewing bearing.
When the slewing bearing fails in the use of mechanical equipment, when dismantling the slewing bearing for maintenance, the appearance of the slewing bearing should be recorded, and the remaining amount of lubricating oil in the slewing bearing should be checked. After the lubricating oil is sampled and stored, kerosene or gasoline should be selected. Simple cleaning of the slewing bearing. The appearance of the bearing and the analysis of the lubricating oil are useful for later judging the cause of the failure of the slewing bearing.

2. Rough wash first and then fine wash.
After rough cleaning, clean the removed slewing bearing, place the slewing bearing on the container, and place the metal mesh as the bottom to prevent the slewing bearing from directly contacting the dirt at the bottom of the container. If the rolling surface of the slewing bearing is damaged, after cleaning the grease with a brush, enter the fine cleaning step, put the slewing bearing into the cleaning oil, and clean it while rotating. If the cleaning oil is dirty, it should be replaced in time to ensure a good cleaning effect.

3. Check the slewing bearing with professional methods.
In order to ensure that the removed slewing bearing can continue to be used, it must be checked after the slewing bearing is cleaned. The inspection items of the slewing bearing include: foreign matter, clearance, dimensional accuracy, wear of the slewing bearing frame, state of mating surface, state of rolling surface, raceway surface state, rolling element running state, etc.

Luoyang FV can not only produce standard slewing ring bearings, but also can design according to customer's requirements and operating conditions, and we can also repair slewing bearings. After the maintenance of the slewing bearing, the customer can obtain the maximum use effect at the minimum cost. Welcome your inquiry!
