Excavator swing bearing china manufacture 011.25.315

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).

Availability
 slewing rings are generally available from stock, and mating pinions for the geared versions are also generally available.

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 swivelsStretch wrapping machinesBottle filling machinesConveyors and related material handling equipment

  • 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.
