What can we learn from the information from the slewing bearing?

The material of the slewing bearing seal is made of oil-resistant nitrile rubber. The codes of the wire end sleeve material and the delivery state of the blank are given in the table. In the table, "T" means that the ring blank is delivered in a tempered state, and "Z" means that the ring blank is delivered in a normalized state.

How is the slewing bearing properly maintained?

However, if the slewing bearing is worn out by the ball or rail, the simple replacement of spare parts will not solve the use problem.Since the wear of the balls inevitably increases the gap, the chain will be damaged in the long run, and the chain has a quenched thickness of about 3–5mm and a hardness of HRc55–62. If the hardened layer is damaged, it quickly becomes unusable after replacement.

So if the internal damage of the slewing bearing needs to be rotated again and deterred with steel balls, this is the best solution. Professional processing equipment is required. If it is confirmed that the rail or steel balls are damaged, it is recommended to contact professional slewing bearing manufacturers and suppliers.

What are the materials of the slewing bearing?

The cage for slewing bearings has integral, segmented, insulated blocks and other structural shapes. The integral and segmented cages are made of 20-gauge steel or ZL102 cast aluminum alloy. The spacer block type is made of 1010 polyamide resin, ZL102 cast aluminum alloy, etc. With the continuous development of the materials industry, nylon GRPA66 has also become. 25 popular and used in the construction of segmented cages.

The material of the slewing bearing seal is made of oil-resistant nitrile rubber. The codes of the wire end sleeve material and the delivery state of the blank are given in the table. In the table, "T" means that the ring blank is delivered in a tempered state, and "Z" means that the ring blank is delivered in a normalized state.

What effects does heat treatment have on slewing bearings?

The manufacturing quality of the slewing bearing itself is strongly influenced by manufacturing accuracy, axial clearance and heat treatment condition. The factor that is easily neglected here is the influence of the heat treatment state. In order to prevent cracks and depressions on the surface of the raceway, it is obviously necessary that the surface of the raceway not only has sufficient hardness, but also a sufficient depth of the hardened layer and a sufficient hardness of the core. According to foreign information, the depth of the hardened layer of the raceway should be thickened with the increase of rolling elements, and the deepest can exceed 6mm, and the hardness of the core should also be high, so that the raceway has a higher crushing strength. Therefore, the depth of the hardened layer on the surface of the raceway of the slewing bearing is insufficient, and the hardness of the core is low, which is also one of the reasons for its damage.

We can see the shadow of the large rolling stock in every aspect of our daily lives. It can be said that a slewing bearing is essential. At LYXQL Slewing Bearing Co., Ltd., you will get the best quality slewing bearings and the most intimate customer service.
