Hydraulic Trailer Brake Cylinder – M16x1.5 Threaded Rod, 70 mm Stroke, Spring Return – SPH340368

Key Features & Benefits

• Single-acting hydraulic operation: Uses hydraulic pressure to actuate compatible mechanical trailer brake linkages.
• Internal return spring: Helps retract the piston rod when hydraulic pressure is released.
• M16x1.5 threaded rod: Accepts compatible threaded clevis ends or other suitable mechanical linkage components.
• 70 mm (2.76") stroke: Suitable for brake mechanisms requiring this working travel.
• G 3/8 BSP hydraulic port: For connection to compatible hydraulic brake circuits.
• Replacement brake actuator: Suitable for repairs where the original cylinder's dimensions and operating characteristics match.

M16x1.5 Threaded Rod – Flexible Connection Options

The SPH340368 features an M16x1.5 male threaded piston rod end, allowing compatible female-threaded clevis fittings or other suitable linkage connectors to be installed.

Depending on the trailer brake linkage, different clevis designs may be used to achieve the required connection arrangement.

Long Adjustable Clevis

An example of an adjustable clevis connection for compatible trailer brake linkages.

Short Clevis Connector

A compact clevis connection example for suitable mechanical brake lever systems.

How Does the Spring Return Brake Cylinder Work?

Hydraulic actuation: When hydraulic pressure is supplied, the piston rod moves and transfers force to the connected trailer brake mechanism.

Spring-assisted return: When hydraulic pressure is released, the internal return spring helps retract the piston rod towards its starting position.

The cylinder's internal spring provides its own return function. Any additional return mechanisms required by the complete braking system must remain in place.

Applications – Agricultural Trailer Brake Systems

This single-acting hydraulic brake cylinder can be used in compatible applications including:

• Agricultural and tractor-towed trailers.
• Farm transport trailers with hydraulic braking systems.
• Suitable slurry tankers and manure spreaders.
• Compatible agricultural machinery brake mechanisms.
• Replacement of existing threaded-rod hydraulic brake cylinders.

Compatibility depends on the complete braking system and its mounting and operating requirements.

Installation & Safety

Install the hydraulic brake cylinder and any threaded linkage fittings in accordance with the brake system requirements. Check the alignment, mounting security and full travel of the mechanism.

After installation, correctly bleed the hydraulic system and check for leaks, proper brake actuation and reliable return movement.
