What kind of turntable are you using on your truck trailer? Ball bearing turntables and slewing rings ?

Trailer Turntable

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

Ball bearing turntables and slewing rings must always be operated as set out in the relevant operating instructions for the particular vehicle.

Compliance with ”TÜV” Safety Regulations and Motor Vehicle Safety Standards (StVZO) is required in Germany. JOST type ball bearing turntables and slewing rings cover the complete spectrum of trailer technology and have a solution to suit all applications.

Design/features

trailer turntable 2

The ball bearing turntables and slewing rings allow the bogie to turn relative to the trailer frame. They transfer both the axial force and the thrust and tensile forces that occur during a journey

trailer turntable 3

The lower ring/outer ring is bolted on to the A-frame and the upper ring/inner ring is bolted to the chassis. The A-frame, ball bearing turntable or slewing ring and chassis must never be welded together. Pre-welded stop blocks relieve the shear load on the bolts resulting from horizontal forces. The ring must be mounted on a completely flat and rigid base with at least 50 % of the circumference adequately supported.
