Wabco 4110033404 Conical Rod Bearing

Description

The Wabco 4110033404 is a conical rod bearing designed for use within air brake systems, specifically as a component in air compressors. This bearing facilitates smooth and efficient operation of the compressor rod, contributing to consistent air supply for braking performance. Its dimensions are 15 x 4 x 38 mm, and it is manufactured to OE specification for reliable compatibility and performance.

Key Features & Benefits

This little piece basically lets things spin smoothly inside your air compressor. It’s a type of bearing, so think of it like a really precise little race track for a rod within the compressor. It reduces friction where the connecting rod meets the crankshaft – that's where it really does its work. It supports the weight and keeps everything aligned as the compressor is pumping air. Now, the air compressor itself is what builds up the air pressure for your truck or trailer’s air brakes, things like the parking brake, the service brakes, and even air horns. This bearing is inside that compressor, so it’s a small part of a bigger system, but a vital one. It allows the compressor to run efficiently and keep that air pressure up. It’s located on the connecting rod assembly inside the compressor.

Symptoms, Risks & Replacements

If this bearing goes bad, you’ll notice it. You’ll likely hear unusual noises coming from the compressor – kind of a knocking or rumbling. The compressor will struggle to build pressure, meaning your brakes won’t work as effectively, and potentially not at all. It acts like a shield, preventing metal – on – metal contact and wear. Without it, parts will grind, overheat, and eventually fail completely. Replacing it is way cheaper and easier than replacing the whole compressor. You can find these conical rod bearings at places like Fixparts Online, and it's usually a pretty straightforward repair if you’re comfortable working on air systems.
