What is the automobile turntable? What is the trailer turntable? What is the casting turntable?

In order to improve the transportation efficiency of vehicles (Trucks, Trailers, tractors), Pull and Drag transportation, especially full trailer transportation, has been widely used. The casting trailer turntable is an important assembly part of the full trailer, which plays the role of steering, bearing and the connection between the main frame and the sub-frame. The trailer turntable is suitable for automobiles and tractors, and belongs to the steering mechanism of trailers.

Ball bearing turntables and slewing rings features:

Ball bearing turntables and slewing rings are parts for fitting onto trailers and agricultural vehicles to connect the vehicle frame to the trailer chassis so it can swivel.

WONDEE ball bearing turntables and slewing rings cover the complete spectrum of trailer technology and have a solution to suit all applications.

The range of applications for ball bearing turntables and slewing rings depends on the maximum axle load. WONDEE ball bearing turntables and slewing rings cover an axle load range from 7.5 to 250 kN.

The specified axle loads for series U, UA, UB, ZA, ZB and UC relate to use where the slewing ring is mounted on the front axle of a trailer with three axles and fifth wheel steering, travelling at speeds of up to 100 kph (65 mph). On dual-axle trailers, the specified axle loads can be exceeded by 10% or 20% at speeds below 30 kph (18 mph).

Ball bearing turntables are available as standard drilled and undrilled, slewing rings are available undrilled. Special drill templates are available upon request.

The materials and production processes are carefully selected to deliver the highest quality. The turntable sections are made of casting formed, CNC, calibrated, high-strength material - nodular cast iron QT500-7. As a result, the turntables can be used even under extreme conditions.

WONDEE turntables guarantee a minimum of down time due to their long service life.

The ball race is secured under load by the axial ball race.

The space inside the turntable is provided with long-lasting protection against dust and dirt by a labyrinth seal.

The sum of all these advantages ensures reliability, freedom of movement and the highest possible service life.
