  • Roller slewing bearing

    Characteristic of structure, performance and applicationThe single row crossed roller slewing bearing is composed of two seat rings, which design in compact structure and light weight, the clearance is small when assembly, so need high precision. The roller are 1:1 cross arranged, it can bear the ax

  • Gear Spur

    Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Though the teeth are not straight-sided (but usually of special form to achieve a constant drive ratio, mainly involute but less commonly cycloidal), the edge of each to

  • Causes and solutions of inflexibility of slewing bearing

    For mechanical products, slewing bearing is an indispensable part, but sometimes we will find that it is inflexible. If it is inflexible, there will be a lot of trouble in use, and there is no way to work well. The following is to share the reasons and solutions of slewing bearing sticking or inflex

  • How to gearing up your slewing ring bearing?

  • Causes of abnormal noise of rotating bearing

    Many mechanical equipment have large and small, a variety of bearings, and the main role of bearings in addition to fixed, but also in the process of mechanical operation to reduce friction, to ensure its accuracy. What is the difference between rolling bearing and sliding bearing? To this end, Chen
Analysis of Accuracy Class of Slewing Bearings

Analysis of Accuracy Class of Slewing BearingsThe slewing bearing is a standard part of hoisting machinery, and its gear accuracy grade should be between 7-11, which determines the stability of the slewing bearing (slewing bearing) transmission, the uniformity of the load distribution and the accura

Teeth hardened of slewing bearing

Gear heat treatmentThe statement of gear heat treatment normally have two statement, normfalizing and tempering. The quenching of gear surface an processed according to customer's requirement, the hardness are in the range of 50HRC~60HRC. In different application, the gear quenching can divide into

Control method of slewing ring noise

Slewing ring is a large bearing that can bear comprehensive load. It can bear large axial, radial load and overturning moment at the same time. Once a problem occurs, it will make a variety of noises. How can we solve these noises? The rotary table bearing manufacturer takes you to explore.1. Contro

Machining deformation of slewing ring

Many users do not know some knowledge about the processing of slewing ring (rotary table bearing). The following small editor of rotary table bearing manufacturer will introduce the causes of processing deformation:1、 Shrinkage of circleAfter the heat treatment of the tooth surface and raceway surfa

Common noise classification and Control Countermeasures of slewing ring

① Dust noise and Its Control CountermeasuresThere are dust and other foreign matters in the rotary table bearing (slewing ring), which will produce aperiodic vibration. The so-called dust sound, its vibration and noise are uncertain, with or without.Control measures for dust noise: improve the clean

What are the model classifications of slewing ring

Slewing ring, also known as rotary table bearing, is a large bearing, which plays an important role in mechanical equipment. It can bear large axial and radial loads and overturning moments at the same time. Although the development history of slewing ring is only 40 years, it has set off an upsurge
