slewing bearing

Single-row crossed roller slewing bearing The single-row crossed roller slewing bearing is composed of two seat rings. It has a compact structure, light weight, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross, which can It can withstand axial force, overturning moment and large radial force at the same time, and is widely used in lifting, transportation and engineering machinery products.

Our company often provides slewing bearings in this field, such as single-row ball type, 011/012.60.2000, 011/012.60.2240, 011/012.60.2500, 011/012.60.2800, 011/012.60.3150, etc., three-row roller type, etc. Slewing bearings include 131/132.45.2500, 131/132.45.2800, 131/132.50.3150, 131/132.50.3550, 131/132.50.4000, 131/132.50.4500, etc., as well as double-row ball slewing bearings 021/022.50 .2500, 021/022.50.2800, etc.

Three-row roller bearings can bear various loads at the same time. They have the largest load-bearing capacity among the four products. They have larger shaft and radial dimensions and a solid structure. They are especially suitable for heavy machinery requiring larger diameters.

Crossed roller slewing bearing is a key component commonly used in construction machinery and lifting equipment. It has the advantages of strong load-bearing capacity, flexible rotation and long service life. Crossed roller slewing bearing, referred to as slewing bearing, is a slewing bearing with rolling elements. Bearing, commonly used in construction machinery and lifting equipment. It realizes return through the rolling of rolling elements Rotating motion, bearing and transmitting loads, while having high stiffness and load-bearing capacity.

The single-row four-point contact ball slewing bearing is composed of two seat rings. It has a compact structure and light weight. The steel balls are in four-point contact with the arc raceway and can withstand axial force, radial force and overturning moment at the same time. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators can all be used.

The three-row roller slewing bearing consists of three races, with upper and lower and radial raceways separated, so that the load of each row of rollers can be accurately determined. It can withstand various loads at the same time and has the largest carrying capacity among the four structural products. It has relatively large shaft and radial dimensions and a solid structure. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel reclaimers, Wheeled cranes, port cranes, ladle rotary tables and large-tonnage truck cranes and other machinery.

1. The work is simple and sensitive, and the rotation resistance is small. 2. The structure is compact and the dimensions (mainly height) are small. 3. Convenient maintenance and long service life. 4. It is composed of ring gear, seal and screws, etc. It is easy to install and convenient for specialized centralized production. 5. There is no intermediate pivot, and other components can be installed in the middle space.

1. With good moment, thrust and radial loading capacity. 2. Suitable for light to medium duty. 3. Easy installation 4. light weight and thin section 5. Flexible rotation

Flange slewing bearings are light in weight, thin in thickness, and flexible in movement. It is widely used in food machinery, filling machinery, environmental protection machinery, etc. The flange slewing ring bearing mainly includes outer and inner rings, grease fittings, sealing strips, gaskets, load plugs and taper pins, and its characteristics are: both the inner and outer rings are L-shaped; the sides of the rings are provided with grease cups, and the outer Steel balls are assembled between the ring and the inner ring. Each ball is separated by a spacer, and the steel ball and the spacer are installed through a load plug and a tapered pin to protect the running of the ball.
