011.30.630 ball slewing ring bearing for civil engineering

Brif introdutions of bearing slewing ring 010.30.560

Slewing ring bearing, also called slewing bearing, is a bearing that can bear large axial load, radial load and overturning moment. Slewing bearings generally have installation holes, inner teeth, outside teeth, lubricants holes and sealing devices, which enable the main frame structural compact, guide reliable, and easy to maintain.

 

 

 

Slewing bearings are divided into various specifications including single-row ball slewing bearings with outer teeth or inner teeth, or without teeth, single-row cross roller slewing bearings, double-row different diameter balls slewing bearings, and three-row roller slewing bearings etc, of which, single-row ball slewing bearings have higher static load capacity; while single-row cross roller slewing bearings have higher dynamic load capacity.

 

 

 

Slewing bearings are widely used for lifting machinery, excavating machinery, construction machinery, port machinery and ship machinery, as well as other larger rotary devices, such as high-precision radar and missile launchers.

VLU Series slewing ring bearings have a rectangular cross-section and range in
size from 4 ¨C 47 inches OD (100 ¨C 1200 mm). They provide optimal econom
and capacity for a given envelope dimension.

Rotary fulcrum bearing includes various types, such as non-dental, inner-dental, outer-dental four points contacting ball bearing, two-bank angle contacting thrust ball bearing, cross roller bearing, and three row roller combination bearing. It is widely used in hoister transportation, mining, architecture, harbor machinery, shipping mechanism, radar machinery of high accuracy, and large-scale rotary devices on aspect of missile launcher.

Design features
The internal configuration is a deep-groove gothic arch raceway, which provides four points of contact with the balls, enabling the bearing to simultaneously carry radial, axial, and moment loads. The use of spacer balls alternated with load balls allows for lower rotational torque and superior performance in applications involving oscillatory movement. Integral face riding bearing seals are provided to assist in the exclusion of contaminants.

 slewing rings are offered in nongeared, internally geared, and externally geared configurations for maximum design flexibility. The gears are Involute Stub designs with 20° pressure angles, manufactured to AGMA Class Q5 quality and .005 to .015 inches allowance for backlash. RK series turntable bearings range in size from 20–47 inches OD (500–1200 mm).

Applications
slewing ring bearing solutions have been used successfully in a variety of light to medium duty applications including:

• Small cranes, booms, and lifts
• Industrial positioners and rotary tables
• Chute swivels
• Stretch wrapping machines
• Bottle filling machines
• Conveyors and related material handling equipment
• Rotating displays

  • The slewing bearing drives in heavy machinery enable higher torque, speed reduction and rotational functions. Applications include solar trackers, digger derricks, truck cranes, wind turbines, utility equipment, hydraulic equipment attachments and tire handlers. Their range of applications make slewing ring bearings an integral part of particular industries, including aerospace, automotive, forestry, manufacturing, medical, military, nautical, power, robotics and surveillance.

    
    

    Here's a look slewing bearings in a few different industries:

    
    

    Slew Bearings for Truck Cranes
    Cranes are uniquely constructed, which means the slewing ring bearing is an essential element of its design. Quality and precision during the manufacturing process are vital to make sure the crane will run after it's been dismantled and reassembled.

    
    

    Slew Ring Bearings for Medical Industry
    Slewing rings in a medical environment need to be highly precise and expertly constructed when it comes to the rings and rolling elements. Slewing bearings must also have some type of sealing solution to prevent leakage in a sterile environment.

    
    

    Slew Bearings for Forestry Industry
    The components of forestry equipment must be strong and durable. The rugged environments they operate in require a design and holding capacity that can withstand the elements. That means that theirslew bearings must be able to operate in conjunction with the high rotating speed of the de-barkers and in cold temperatures.
