Key Components and Their Functions

The JOST TAPE Fifth Wheel 37C Repair Kits consist of three primary components: the wear ring, lock jaw, and wedge. Each component plays a vital role in ensuring the safety and stability of trailer operations.

Wear Ring

The wear ring is a critical component that reduces friction between the trailer and the tow vehicle, ensuring smooth operation during cornering. Forged from high-strength metal, the wear ring is designed to be wear-resistant and durable, maintaining stability even under prolonged use. By minimizing lateral forces, the wear ring prevents excessive sideslip during turns, enhancing driving safety.

Lock Jaw

The lock jaw ensures the fifth wheel remains securely fastened to the base, preventing loosening or detachment during transit. Crafted from high-strength alloy steel, the lock jaw offers exceptional tensile strength and corrosion resistance. When connected, it firmly grips the trailer’s locking mechanism, creating a reliable link between the trailer and the tractor.

Wedge

The wedge is designed to adjust and secure the fifth wheel’s position for different trailer types and heights. Forged from durable alloy steel and special materials, the wedge provides high strength and longevity. During installation, it ensures proper alignment and connection between the fifth wheel and the trailer, accommodating varying configurations.
