Four-point Contact Ball Swing Bearing with Deformable Rings

5 0 Reviews
The four-point contact ball bearings are radial single row angular contact ball bearings featuring raceways that can handle axial loads acting in both directions. A limited radial load can be supported for a given axial load.

Four-point Contact Ball Swing Bearing with Deformable Rings.In general, the slewing bearing rolling elements are integrally hardened carbon-chromium bearing steel. The grade is made of GCr15 or GCr15SiMn steel; the slewing bearing ring is made of surface hardened steel. When the user has no special requirements, it is generally made of 50Mn steel, but sometimes it can be provided according to the needs of some special applications. For the specific conditions of use, other grades of surface hardened steel, such as 42CrMo, 5CrMnMo, etc., are selected.

Four-point Contact Ball Swing Bearing with Deformable RingsHow to Purchase Slewing Support, many new contacts do not know how to choose, want to buy or customize the slewing bearing but do not know which model to use, do not know how to do the initial selection.

1. Determine the large load (axial load, radial load, overturning moment) that the slewing bearing is subjected to when it is in a static state according to the use environment. Use this large load as a static rating.

2. Determine the static safety factor based on the type of machine installed.

3. Refer to the slewing bearing catalogue of the extension slewing bearing to initially select the slewing bearing model and determine which formula is used to calculate the static reference loads Fa' and M'.

4. Calculate the static reference loads Fa' and M'.

5. Find the static load-bearing curve corresponding to the slewing bearing of the selected model in the Slewing Bearing Product Catalogue, marked in the graph (Fa’, M’)

6. Check if the coordinate point is within the static bearer authority.

7. Check the bolt bearing capacity.

8. Complete preliminary selection.

Four-point Contact Ball Swing Bearing with Deformable Rings. As supplied slewing rings are generally packed for storage in a covered store and for a period not exceeding 6 months.

Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.

In extreme cases after long term storage bearings may need professionally reconditioning before installation.When unwrapping, care must be taken not to cut and damage the integral seals.
