Description

Overview

The Bartlett 95mm 375DX compression spring provides spring force within the truck-side clamping assembly of the 95mm Bartlett ball coupling. Replace it when the original spring is cracked, corroded, distorted or has lost tension.

Features

• Replacement spring for the 95mm 375DX truck-side coupling assembly.
• Fits beneath the operating handle within the coupling clamp mechanism.
• Single helical compression spring for service or rebuild work.

Specifications and Materials

Product type: helical compression spring for the 95mm truck-side ball coupling clamp. Mounting position: within the 375DX clamping assembly. The pack contains the spring only.

Part number: TC0530.

See the official Bartlett coupling guide

Compatibility and Fitment

Match the coupling to the 95mm 375DX truck-side ball assembly before ordering. Because the 127mm 59DX coupling uses a larger spring, do not substitute it. Also compare the spring with the old part’s diameter, free length and seating position before fitting.

Compliance and Safety

When replacing the spring, inspect the cap, clamping bolt, main bolt, locking hardware and spring seats. Reassemble the coupling correctly and confirm the clamp moves freely, seats fully and remains secure before towing.

Trailer Applications

Workshops replace this spring during 95mm Bartlett coupling repairs on truck-side towing systems for rigid drawbar pig trailers and hinged drawbar dog trailers. The complete 375DX system carries ratings of up to 7,000kg ATM in rigid drawbar service and a 70kN D-value in hinged drawbar service.

Why Choose ICS Trailers

Correct spring selection matters because the 95mm and 127mm Bartlett assemblies use different compression springs, and a similar-looking coil may not provide the required fit or clamp action. ICS Trailers can help compare the coupling model, old spring dimensions and surrounding clamp components before supply. For a broader repair, inspect the cap, main bolt, clamping bolt and retaining hardware so worn parts are not returned to service around a new spring.
