precision bearings for Industrial robotics and warehousing robotics

Under the influence of international environment, it has become an inevitable trend to develop industrial robot industry vigorously

Slewing bearings plays an important role in the development of industrial robots.It’s called the joint of the machine.

Industrial robots are widely used in manufacturing workshops

HGB offers bearings for Industrial robotics and warehousing robotics, We can produce according to sample or drawing, to meet customers’ different requirements.

SHF crossed roller bearing with mounting holes (for SHF/SHG harmonic drive reducer)

Larger size double row ball slewing bearing exported to South korea

This month we ship the big size double row ball slewing bearing to Korea

This double row ball bearing have three seal ring ,The steel ball and isolators can be directly arranged into the upper and lower raceways .
Double-row ball slewing bearing can carry axial load, tilting moment and radial loads at the same time. The top ball mainly carries the axial load and positive tilting moment. The drop ball takes the opposite tilting moment. This is the reason for the loading capacity of the double row ball slewing bearing being larger than the four-point contact ball slewing bearing; however, the frictional ratio is much larger. than the latter.

Slewing Rings for Radar Military

Our special design Radar military slewing rings are popular in satellite antennas, tank, santi-aircraft gun, radar, missile launcher and so on.

We can produce steel, aluminum and titanium bearings for the most demanding and prestigious customer that matching the highest technical requirement.

Anyway, to ensure the quality of this application, the slewing rings (turntable bearings) should be obtained by a specific process of grinding. As a result, capacity, low torque, stiffness, high rotating speed and precision in rough environments can be available.

Slewing Ring bearings and turntable bearings are large bearings primarily designed to handle applications that feature axial, radial, and moment loads.

Due to this functionality, slewing Ring bearings can be found in the following industries: medical, crane, nautical, military, forestry, material handling, aerospace, machine tools, surveillance, automotive, turntables, mining equipment, offshore platforms, offshore platforms, radar and satellite antennas, robotics and so on. In addition, according to the type of load, slew rings are available with 1 row of balls, 2 rows of balls and one row of rollers as well as there rows.

Slovakia PSL slewing bearing we can customized

We supply OEM slewing ring to customer according to PSL standard and specification, the quality of our product is same as original PSL slewing ring bearing.

Slewing bearing for public works machine excavator

Slewing bearings are widely applied in machines for public works. Usually the slewing rings for public works need to have high rigidity, undertake heavy loads, provide stable rotation, and resistant to impact load. Easy to disassemble or install is also an important factor.

Slewing bearing for excavators
(crawler excavators, wheel excavators, light duty excavators, etc.) Big size slewing bearing with external gear teeth or internal gear teeth are often used on the base of the excavator, which connecting the cabin and the base. Small size slewing bearings are often used in the swiveling boom of the excavators.
We can provide many brand of excavator slewing bearing , like Caterpillar, Komatsu ,Dawoo,Hitachi and so on

HGB Slewing Drive Simple Introduction

The slewing drive is a full-circle slewing reduction transmission mechanism that integrates a driving power source. It uses a slewing bearing as a transmission follower and a mechanism attachment. By attaching a driving member and a drive source to one of the inner and outer rings of the slewing bearing And the cover, and the other ring is used as both the driving follower and the connection base of the driven working part. This makes use of the characteristics of the slewing bearing itself as a full-circle slewing connector to efficiently configure the driving power source and the main transmission. Parts, making it a universal reduction transmission mechanism that integrates slewing, deceleration and driving functions, yet has a simple structure and is easy to manufacture and maintain.

According to the type of variable speed transmission of slewing drive, it can be divided into toothed slewing drive and worm gear slewing drive, inheriting the characteristics of gear drive and worm gear worm drive. These two types of slewing drive can be adapted to medium and high-speed applications In terms of load-carrying capacity, the worm gear and worm gear perform better than the tooth type. When the envelope worm drive is used, its load-carrying capacity, anti-deformation ability, and transmission rigidity are further improved. However, the worm gear worm rotary drive is more efficient in terms of efficiency. Inferior to toothed slewing drive.

According to the openness of the slewing drive transmission, the slewing drive can be divided into open and closed. Generally, the open structure is mostly used in applications where the environment is too harsh and the maintenance and repair cycle is short. Inspection, maintenance, and service are also easier to replace. Where the environmental conditions do not change much and the environment pollution level is below moderate, the closed structure can provide a long maintenance life cycle.

Insufficient High End Market for Slewing Bearings

China’s slewing bearing market demand will be saturated. In view of the fact that China’s slewing bearing production tends to be saturated at present, it has few high-tech contents and the quality is not too hard. Looking at the market of excavators with high requirements for slewing bearing tooth quenching and raceway quenching, domestic excavators are used in projects. All imported equipment, Komatsu in Japan, Hyundai in Korea, and Caterpillar in the United States, although the price is expensive, the construction unit still selected it. The main reasons for purchasing capital are high quality, key components with high reliability, long service life, and easy damage. The anchor cannot be thrown at critical times, the construction period cannot be delayed, credibility cannot be affected, and some engineering disputes can be avoided.

news

There are many factors restricting the development of China’s excavators, but the quality of mechanical parts, such as slewing bearings and hydraulic components, is not hard, which is an important link. From the comparison with foreign slewing bearings, the materials and heat treatment technology and tooth hardening technology of domestic slewing bearings are far behind. This requires the unremitting efforts of the majority of engineering and technical personnel to study hard and strive to catch up with the world’s advanced technology as soon as possible for slewing bearings. Go abroad and lay the foundation for the world.

Application of Slewing Drive

The slewing drive is a new type of slewing product, usually called slewing bearing. It is usually composed of the worm, slewing bearing, housing, motor, and other components. Because the core component adopts slewing bearing, it can bear axial force, radial force, and overturning moment at the same time.

Application areas of the rotary drive

Compared with the traditional rotary products, the rotary drive has the advantages of simple installation, easy maintenance, and greater installation space-saving. This product can be widely used in construction machinery and new energy fields such as solar tracker systems, heavy-duty flatbed trucks, container cranes, truck-mounted cranes, aerial work vehicles, wind power generation and so on.
