How to select crane slewing bearing type ?

Swing bearings

SLEWING RING BEARINGS

Slewing ring bearings is a bearing that can bear a lot of weight, often used in different industries.And there are many types of swing bearing, different types have different use case.But generally speaking, slewing ring are more used in construction machinery, so what type of slewing bearings should be used by cranes?

FRB BEARINGS technology personnel according to their years of related experience, according to crane is a large machinery, so choosing the slewing bearing must have a lot of tolerance, and compact structure.Therefore, the crane slewing bearing can choose three rows of roller type turntable bearing, single-row four-point contact ball type slewing ring, which can increase the overall contact area and withstand various loads at the same time. The diameter of this type slewing ring bearing is also large, which is specially used for heavy machinery equipment.

What’s the failure analysis and renovation of slewing ring bearings?

Three row roller slewing bearings

THREE ROW SLEWING BEARINGS

Slewing bearings are special types of bearings usually used in heavy machinery.The difference between these types of bearings and ordinary bearings is that they have high pitch value diameters, the way they are mounted on a structure, generally “static” working properties, high load capacity and a large number of rolling elements.

The slewing bearing is usually selected according to the static load which is calculated by the axial and radial force and the tilting moment.Some parameters, such as speed, load and working temperature, are needed to properly select the rotating bearing.There are some assumptions to consider:
1) The bearing is made of high-quality materials without manufacturing defects.
2) Select bearing according to load calculation.
3) The bearing mounting is suitable.
4) The grease quality is good and it can reach every corner of the bearing.
5) The bearing is sealed with high-quality seals.
6) The bearing working temperatureis within the range.
7) Ensure proper maintenance.

China slewing ring HJB710 crossed roller swing bearing

slewing ring bearing

SLEWING RING BEARINGS

HJB710 toothless cross roller slewing ring , external dimension:608*812*75mm , weight:111kg. Production and supply the inner diameter:200mm- 5000mm, the inner teeth, no teeth cross cylindrical roller slewing bearings.This kind of bearing is a compact bearing with an orthogonal arrangement of rollers between inner ring and outer ring.The rolling surface is linear contact, so the elastic displacement caused by bearing load is very small, and can simultaneously bear the complex combined load such as radial load, axial load and torque.

Such bearings are widely used in rotating parts of industrial robots, machine tools and medical equipment that require small, high rigidity and high rotation accuracy.

The following are some product models:
