First of all, we should pay attention to three problems when we choose slewing bearing: load, bolt strength and whether the bolt hole is uniform.If the bearing is installed on the support surface which lacks integrity, local deformation will change the load, resulting in different load sizes of the

Slewing ring is a kind of large-size thin-walled parts, widely used in construction machinery, wind power and other fields. The slewing system of slewing ring is redundantly driven by the meshing of several circumferential distributed pinions with the inner ring teeth of slewing ring, so the deforma

Rotary table bearings are used in many fields such as engineering machinery, ships, wind power and so on. What are the commonly used materials of rotary table bearings?Usually, 50Mn is selected for the rotary table bearing housing, but sometimes 42CrMo is selected to meet the host requirements of sp

Gear shaping is also a widely used tooth profile machining method, which is often carried out together with gear hobbing. It is equivalent to meshing a pair of cylindrical gears, and the gear shaper cutter is equivalent to a modified gear. During gear shaping, the gear shaping cutter moves up and do

1. Introduction of Xuzhou Helin slewing ring bearings Xuzhou Helin is a professional manufacturer in slewing ring bearings. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different

Slewing bearings (slewing bearings) are mostly used in some large mechanical equipment because they have to bear heavy load. Therefore, they will inevitably suffer certain friction and loss in the process of use. However, what's the matter with the rapid loss of slewing bearings?Excessive wear of sl
