China Slewing Bearing Manufacturing
Light Slewing Bearing

Light Slewing Bearing

light slewing bearing, also known as a light-duty slewing bearing or small slewing bearing, is a type of slewing bearing designed for applications that require lower load capacities and compact design. These bearings are typically used in light-duty equipment and machinery where space and weight considerations are important.
Flange Slewing Bearing

Flange Slewing Bearing

Flange Slewing Bearing & Light Slewing Bearing, Compared with normal type slewing bearing, the slewing bearings with flange has less weight but the same flexible when rotate, so when the machines have space limit and weight limit, then the slewing bearing with flange is the best choice. when produce this kind of slewing bearing, the key quality control is the run-out of the surface, ZZ engineer is with rich experience in such problem
Single Row Ball Slewing Bearing

Single Row Ball Slewing Bearing

single-row ball slewing bearing, also known as a single-row ball slewing ring or single-row ball turntable bearing, is a type of slewing bearing that consists of a single row of balls arranged between an inner and outer ring. This design allows for smooth rotational movement and the transmission of both axial and radial loads.
Single Row Crossed Roller Slewing Bearing

Single Row Crossed Roller Slewing Bearing

single-row crossed roller slewing bearing, also known as a single-row crossed roller slewing ring, is a type of rolling element bearing specifically designed for applications that require high axial and radial load carrying capacity combined with precise rotational movement. It consists of an outer ring, an inner ring, and crossed cylindrical rollers that are oriented at a 90-degree angle to each other. Here are some key aspects of single-row crossed roller slewing bearings
Double Row Ball Slewing Bearing

Double Row Ball Slewing Bearing

Double-row ball slewing ring with same diameter balls is usually used for wind driven generators and concrete pump trucks, Excavator, Crawler crane, Port machinery, Amusement facilities. In wind driven generator applications, double-row ball slewing ring is often installed at the bottom of propellers for variable pitch control which requires zero clearance, large start friction moment and high running accuracy.
Three Row Roller Slewing Bearing

Three Row Roller Slewing Bearing

Three-row roller slewing bearing decreases the bearing diameter by distributing the loads in different directions to different rows of raceways and rollers, which makes the slewing ring more compact and improves the load capacity. Three-row roller slewing ring is ideal for lifting, mining, material transportation, marine, and other engineering machinery.
Four Point Contact Ball Bearing

Four Point Contact Ball Bearing

Four-point Contact Ball Bearing comprises an inner ring and an outer ring. Featuring compact design, light weight and four-point contact ball configuration, this slewing ring is designed with excellent dynamic load capacity to handle axial, radial and tilting moment loads. Four-point contact ball slewing rings are particularly versatile and are widely used in cranes, lifting equipment and other engineering machinery.
Slewing Bearing With External Gear

Slewing Bearing With External Gear

Slewing Ring Bearing With External Gear is with gear on the external ring, it is processed by a gear shaping machine. Customer can prefer the gear hardening treatment or not according to the working condition, if it need high load and press, we advise to do hardening treatment. Due to the gear is on the outer ring
Application of slewing bearing
Slewing bearing for port crane

Slewing bearing for port crane

Three row roller slewing bearing can bear different loads simultaneously. The capacity load is the largest one comparing with other type slewing bearing. Due to the large axial and radial dimension & solid structure, it is especially suitable for heavy-duty machinery, such as harbor crane,ship crane, etc.
Slewing bearing for Aerial platform vehicles

Slewing bearing for Aerial platform vehicles

A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill.
Slewing bearing for Truck crane

Slewing bearing for Truck crane

A slewing bearing is a large rolling-element bearing that allows the upper structure of a crane to rotate horizontally. It is a critical component that enables the crane to swing and pick up loads.
Slewing bearing for Ferris wheel

Slewing bearing for Ferris wheel

Ferris wheel slewing bearings are large ring-shaped roller bearings that allow the main wheel structure to rotate smoothly around the central axle.
Slewing bearing for Filling machine

Slewing bearing for Filling machine

Light type slewing bearing is designed with compact structure, light weight and flexible rotation. Filling machine is using such slewing bearing is realize continuous and stable automatic filling.
Slewing bearing for Excavator

Slewing bearing for Excavator

The slewing bearing allows the upper structure of an excavator to rotate horizontally on top of the undercarriage. This enables the boom, arm and bucket to swing 360 degrees.
Slewing bearing for Mud scraper

Slewing bearing for Mud scraper

Mud scrapers are heavy construction equipment used to clean and flatten soil surfaces. They need to rotate their scraping blade to level terrain.
Slewing bearing for Welding Robot

Slewing bearing for Welding Robot

Single Row Four Point Contact Ball Slewing Bearing and single row cross roller slewing bearing is designed in compact structure, high manufacturing precision and small clearance. Welding robots use such slewing bearings to slew and turn the workpiece, realizing automatic welding.

Specialises in designing and producing bespoke slewing bearing to meet customers specific requirements.
