A 15-Ton Semi-Trailer Ball Bearing Turntable, commonly known as a Ball Race or Fifth Wheel Turntable, is a critical articulation component installed on the front of a semi-trailer. Its primary function is to connect the trailer to the towing vehicle (tractor truck or dolly) while providing a smooth, low-friction pivot point.
This device allows the trailer to articulate vertically (for uneven ground) and horizontally (for turning), ensuring stable and maneuverable transportation. The "Ball Bearing" design signifies the use of a circular race of hardened steel balls seated between the upper and lower plates. This design is renowned for its high load capacity, durability, and smooth rotation under heavy loads, making it the industry standard for robust logistics, construction, and heavy-haul applications.

The 1000mm diameter Jost turntable slewing ring trailer ball bearing turntable is a critical component for heavy-duty semi-trailers, enabling smooth articulation between the trailer and tractor during turns. Designed for extreme load capacities and harsh operating conditions, it minimizes friction, enhances maneuverability, and prolongs the lifespan of the trailer's steering system.
