What information do you get the slewing bearing?

The slewing bearing is a new type of mechanical parts consisting of inner and outer rings, rolling elements, etc. is. The slewing bearing is a large bearing that can bear comprehensive loads and can accommodate large axial and radial loads and tilting moments equal time.

What series of slewing bearings are there?

Single row slewing bearing

The single volleyball slewing bearing accommodates a series of steel balls as rolling bodies, and between the steel balls there is a single insulation block. The inner and outer rings are one-piece and the steel ball is installed through the blocking hole. The steel ball rests at four points on the raceway and can simultaneously absorb axial force, radial force and tilting torque. It is the first choice for small and medium sized slewing bearings with a diameter of less than 1800 mm.

Double row four-point ball joint

The structure of the double row four-point ball slewing bearing is similar to that of a single volleyball slewing bearing. The difference is that two rows of steel balls are used as rolling body, the size of the two rows of steel balls is equal, and a single insulation block is arranged between the steel balls. The inner and outer rings are one-piece and the steel ball is installed through the blocking hole. It is the preferred product for the main engine with heavy load and limited radial structure size.

Three-row column wreath

The three row column slewing bearing is a kind of slewing bearing with high load capacity, which is mainly used in high load operation occasions. It consists of three clamping rings, and the upper and lower roller rows are horizontally distributed to carry the axial force and the tilting moment from two directions. The radial force is absorbed by the third vertical row of rollers. It is the choice for a large slewing bearing with a diameter of more than 1800 mm.

What factors should be considered when buying slewing bearings?

1. When purchasing slewing bearings, consider more specific working conditions, axial force, radial force and tilting moment. Rotate a slewing bearing of suitable size

2.When purchasing slewing bearings, more specific requirements for accuracy of use should be considered and the type of slewing bearing should be selected.

3.Choose the slewing bearing according to the specific application environment, temperature and other special requirements!

Cross roller slewing bearing

The cross roller slewing bearing is similar to the volleyball single slewing bearing. There is only one row of rolling elements. The rolling elements are cylindrical rollers. The axes of the adjacent rollers are arranged in a 90° cross. The inner and outer ring each have two raceways, and the raceway section is linear. Half of the rollers bear the downward axial force and half the upward axial force.

Double row reducer ball joint

The volleyball double swivel joint has three seat rings. The steel balls and insulation blocks can be discharged directly into the upper and lower raceways. Depending on the load condition, the upper and lower rows of steel balls with different diameters are arranged. This type of open mounting is very practical. The bearing angle of the upper and lower arch raceways is 90°, which can accommodate large axial forces and tilting moments. If the radial force is greater than 0.1x the axial force, the raceway must be specially designed. The axial and radial dimensions of the double volleyball slewing bearing are relatively large and the structure is fixed. It is especially suitable for tower cranes, truck cranes and other loading and unloading machines that require medium or larger diameter.
