Description

Overview

OMS 50mm Bolt-In King Pin suits trailer skid plates where you want a replaceable king pin without cutting or rewelding. The bolt-in format lets you service the coupling point more predictably while keeping the skid plate assembly intact. As a result, it is a practical choice for workshops and fleets that need consistent turntable coupling fitment.

Features

• Bolt-in king pin design to support quicker skid plate servicing
• 8-bolt retention plate pattern for common bolt-in installations
• Stated 190kN D-rating to suit heavy trailer coupling loads
• Heat-treated steel pin and high-tensile retaining bolts per the product specification

Specifications and Materials

Part number: TT4301.
OMS 50mm Bolt-In King Pin uses the materials and fastener grades listed below.

For compliance context, refer to the Directive 94/20/EC text on EUR-Lex

Compatibility and Fitment

Confirm you are fitting a 50mm king pin and not a 90mm variant before ordering. Check the skid plate and retention plate drilling to suit an 8-bolt pattern, then torque fasteners to the requirements for your assembly. The product specification states 50mm and 90mm bolt-in king pins interchange with the same retention plates, however you must still verify the correct king pin diameter for your turntable coupling.

Compliance and Safety

The product specification states this OMS 50mm Bolt-In King Pin was tested and approved at a 190kN D-value in accordance with 94/20/EC. Keep the coupling interface clean and inspect the king pin and retention hardware for wear, scoring, or looseness during routine servicing. Replace damaged fasteners and do not reuse bolts if your workshop procedure or the hardware supplier specifies single-use locking types.

Trailer Applications

Use the OMS 50mm Bolt-In King Pin on articulated trailer skid plates where a 50mm king pin interfaces with a compatible turntable coupling. For example, it can suit semi-trailer applications that rely on a bolt-in retention style for easier component replacement. It can also support fleets that want consistent maintenance outcomes across multiple trailers.

Cross-reference and Suitability

No verified equivalent part numbers were identified for this king pin during research. Instead, match by king pin diameter, retention pattern, and the stated D-rating to confirm suitability.
