Secure Driveline Torque with CLAMPLOCK Technology

Australian-Engineered Driveline Locking Innovation

CLAMPLOCK is a proprietary spline locking technology developed by OEM Dynamics to eliminate backlash,
prevent spline wear, and deliver superior torque transmission in critical heavy-duty driveline systems.

Engineered and manufactured in Australia, CLAMPLOCK provides a secure, uniform mechanical lock between
mating spline components — without keyways, stress risers, or shaft damage.

Built for demanding mining, transport, and industrial applications where failure is not an option.

The Problem with Traditional Driveline Connections

Conventional splined driveline interfaces often suffer from micro-movement under load. Over time, this leads to:

• Fretting corrosion between contact faces
• Progressive spline wear and backlash
• Torque transmission losses
• Vibration and noise under load
• Accelerated component fatigue
• Increased maintenance downtime

How CLAMPLOCK Spline Locking Technology Works

CLAMPLOCK uses a precision-engineered external clamping mechanism to apply uniform radial compression around the spline interface.

This creates a rigid mechanical lock that:

• Eliminates spline play and driveline backlash
• Prevents micro-movement under cyclic loading
• Prevents spline fretting and wear
• Improves operational smoothness
• Reduces maintenance intervals
• Distributes load evenly across contact surfaces
• Removes stress concentrations common with keyed systems
• Protects shaft integrity
• Enables rapid installation and removal

Unlike interference fits or keyed assemblies, CLAMPLOCK maintains torque integrity without inducing material stress or permanent shaft deformation.

Australian Designed & Manufactured

CLAMPLOCK technology was developed in Australia by OEM Dynamics to meet the reliability demands of harsh industrial environments.

Why Australian engineering matters:

• Designed for mining and heavy-duty mobile equipment
• Built to withstand shock loading and extreme torque conditions
• Supported by local engineering expertise
• Manufactured with precision quality control

This ensures dependable performance where imported generic systems often fail.

In-House Engineering & Manufacturing

Unlike catalogue-only suppliers, OEM Dynamics designs and manufactures CLAMPLOCK® systems entirely in-house.

This end-to-end control allows our engineering team to adapt CLAMPLOCK technology to suit specific customer equipment, torque requirements, and installation constraints.

What this means for OEMs and engineers:

• Custom spline interface configurations
• Integration into proprietary driveline designs
• Rapid engineering modifications
• Controlled manufacturing tolerances
• Consistent quality assurance
• Local technical collaboration

Whether you require a modified companion flange, integrated coupling system, or a fully customised driveline solution, OEM Dynamics can engineer CLAMPLOCK technology to match your application.
