Wabco 7234078808 Cylinder

Description

This Wabco cylinder is a critical component within air brake systems, specifically air valves. It's designed to convert pneumatic pressure into linear motion, enabling the activation of brakes in commercial vehicles and trailers. This cylinder features a 127.0 mm diameter and a 120.0 mm stroke, with dimensions of 155 x 490 x 160 mm. Constructed to OE specification, this device provides reliable performance and durability under demanding conditions. The cylinder utilizes a cam-type operation and is equipped with a boot, ensuring consistent and long-lasting functionality across a temperature range of -40°C to +80°C, while operating effectively up to a maximum pressure of 10.0 bar. It features M14 x 1.5 and M16 x 1.5 port threads and a screwed yoke.

Key Features & Benefits

This thing basically takes air pressure – from your air compressor – and turns it into mechanical motion. It’s a piston inside a tube, and when air pushes on that piston, it extends or retracts. That movement is what actually does the work, whether it's applying the brakes, or activating something else in the air system. It's pretty simple in principle, but vital for everything to work smoothly. In your brakes, this cylinder is usually directly connected to the brake chambers on the wheels. When you hit the brake pedal, air goes into these cylinders, the piston moves, and that pushes on the brake shoes or pads to slow the vehicle down. It’s a key part of how air brakes actually apply the stopping force. You’ll see them on trucks, trailers, buses… anything using air brakes.

Symptoms, Risks & Replacements

Well, if this cylinder fails, you lose braking power. That’s obviously a big deal. Think of it like this: it acts like a shield between the air pressure and the actual mechanical force that stops the vehicle. If the cylinder leaks, or the piston gets stuck, the brakes won't work right. You’ll notice if one fails because the brakes will feel weak on that wheel, or maybe it won’t apply at all. It's a safety item, plain and simple. If you're looking to replace one, Fixparts Online has a good selection, and getting a quality replacement is really important here.
