The single row crossed roller slewing bearings are arranged at right angles to each other at intervals between the inner and outer wheels. They can withstand loads from all directions (such as axial, thrust or momentum loads). Since the roller is in linear contact with the surface of the track, the bearing is less likely to be elastically deformed by the load. The single row crossed roller slewing bearing can be assembled in all directions of the spindle for easy use. It can withstand radial and axial loads at the same time, thus simplifying the structure of the device and reducing the weight of the mechanism. Read More

With the gradual rise of new energy fields, the accompanying equipment manufacturers have sprung up. The slewing drives are derivatives of slewing bearings, which are used in different fields. Read More

Slewing support is widely used in real industry. It is called "the joint of machine". It is an important transmission element for the machinery that needs relative rotation motion between two objects and bears axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing bearings have been widely used in marine equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial robots, tunnel boring machines, rotary stage lights. Next, we briefly introduce the four point contact ball bearing and light slewing bearing, and briefly analyze the difference between them, hoping to help you better understand the four point contact ball bearing and light slewing bearing.

Slewing bearing is a kind of large bearing which can bear comprehensive load, and can bear large axial, radial load and overturning moment at the same time. Slewing ring usually has installation holes, internal or external gears, lubricating oil holes and sealing devices, so it can make the main engine design compact, easy to guide and maintain. It has four series: teeth-type, outer-type and inner-type four-point contact ball bearings, double-row angular contact ball bearings, cross-cylindrical roller bearings, cross-tapered roller bearings and three-row cylindrical roller composite bearings. Slewing rings are widely used in marine equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries. Read More

The three row roller slewing bearing is the one with the largest bearing capacity, and the shaft and radial dimensions are both large and firm. Generally used in heavy duty machinery. Many of the heavy machinery used in our lives are three row roller slewing ring bearings, but many people do not understand its specific information. This article aims to describe the three row roller slewing bearing in detail. Read More

Slewing bearings are widely used in marine equipment, engineering machinery, light industrial machinery, metal machinery and other fields. Operating machinery, medical machinery, industrial machinery and other industries. This article briefly introduces its four types, allowing you to understand it more intuitively. Read More
