Note:
- Ball & Roller combined slewing bearing is applied for heavy axial loading, the eccentric rate(e) less than 1.2 and continuous rotating and long life.
- Refer to Table A if slewing bearing are stuck with double row sealing; Refer to Table B if slewing bearing are with labyrinth seal.
- If you need more information about the structure please contact with us.
- The gear torque is under atmosphere of Q&T
The double rows ball slewing ring consists of two parts slewing rings, which can withstand large axial loads, radial loads and titling moments, and has a higher safety factor. It is widely used in medium and large cranes, mining equipment, excavators and other mechanical equipment.
HJ series slewing bearing internal rolling body is roller, which is installed by crossing. It also provides internal gear, external gear and toothless structure. It has the characteristics of small assembly clearance, high precision and stable operation. Widely used in the field of test platforms, military products, artificial intelligence.
The J series use the structure of the cross roller to provide high precision with high load capacity. It is mainly used in the construction industry, such as concrete pump trucks, tower cranes and wheel cranes.
The same four-point contact design as our single-row four-point contact ball slewing ring (01 series) is more thinner and provides excellent torque, thrust and radial load capacity. Ideal for applications such as truck mounted cranes, cranes and non-precision industrial work benches etc.
The HS series can be customized to meet the user's different working conditions and normal working conditions in the environment, providing excellent axial, radial and titling moments. Mainly used in radar, military turrets, machine tools and excavators.
Turntable bearing is a kind of large bearing with special structure which can bear the comprehensive loads such as axial load, radial load and overturning moment at the same time. Generally speaking, the turntable bearing is equipped with installation hole, lubricating oil and sealing device which can meet the different requirements of all kinds of main engines under different working conditions. On the other hand, the turntable bearing has the characteristics of compact structure, easy to guide rotation, easy to install and easy to maintain, etc. The turntable bearing is widely used in large rotary devices such as hoisting and transportation machinery, excavators, construction engineering machinery, port machinery, wind power generation, medical equipment, radar and missile launcher.
Single row cross roller slewing bearing consists of two rings, compact structure, light weight, small clearance, so high precision is required.Roller adopts 1:1 cross arrangement, can bear axial force, tilt moment and relatively large radial force.It is widely used on lifting, transportation, construction machinery and military products.
Double row contact ball slewing bearing has three rings, balls and spacer blocks can be arranged in the upper and lower rings directly, Install two rows different diameters balls according to the stress conditions.This kind of open assembly is very convenient, for the upper and lower raceway arc Angle of 90°, can bear large axial force and tilting moment.When the radial force is greater than 0.1 times of the axial force, special raceway design is required.This types slewing bearings have large axial and radial dimensions and strong structure, so it is especially suitable for middle diameter tower crane, truck loading crane and other loading and unloading machinery.
