cross roller slewing bearing

  • Single Row Cross Roller Slewing Bearing (11 Series)

    The single row cross roller slewing bearing is made of two seat rings. It is featured with compact structure, light weight, high manufacturing accuracy, small assembly gap and high requirement for installation accuracy. Rollers are 1:1 cross- arranged through spacers. It can bear axial force, overturning moment and large radial force at the same time. Compared with ball slewing ring, the axial and radial clearance of the cross roller slewing ring is smaller than single row ball slewing bearing. While the rotating is not so flexible as the single row ball slewing bearings, usually it is used for some higher precision applications. It is widely used in lifting transportation, construction machinery, military product, robots, medical equipment, grinding and drilling machine etc. Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc.

  • Heavy Duty Slewing Bearing For Port Crane Equipment

    Port hoisting machinery generally includes portal cranes, ship unloaders, floating cranes, etc., commonly used single-row four-point ball type, three-row roller type and double-row ball type slewing ring bearings. Port cranes usually use three-row roller slewing bearings with internal or external teeth with a diameter of 4 meters to withstand high overturning moments. 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., are our main advantage products. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc., you can call for details.

  • Slewing Bearing For Ferris Wheel

    In amusement equipment, slewing bearings are used in Ferris wheels, large pendulums, and flying chairs. Broadly speaking, a slewing bearing is a large bearing that can withstand comprehensive loads, and can bear large axial, radial loads and overturning moments at the same time. Slewing bearings generally have mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, so that the design of the main engine can be compact, easy to guide, and easy to maintain. Ferris wheel usually adopts double row ball slewing bearing. There are two rows of rolling elements, which can bear large axial load, radial load and tilting moment. It rotates flexibly and stably with higher safety factor. For some large ferris wheel, four contact ball slewing bearing is selected too, outer dia is about 4100mm, depth 85mm. Slewing ring bearings used on Ferris/Sky wheels are used with inner rings. In most cases, the bearing should be light enough and safe enough to rotate. The slewing ring bearings used on the Ferris wheel/sky wheel generally require a long service time, so it is also very important for anti-corrosion. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc.
