Martin’s Rubber explain all about rod seals
With the market flooded with different varieties of rubber seals, it can be difficult to select the right type of seal for a given application. Here, Martin’s Rubber talk us through what rod seals are, how they work and their advantages.
What is a rod seal?
Rod seals are often the decisive factor in ensuring that a hydraulic cylinder operates at peak performance. Leakage through the rod seal can lead to environmental damage and accidents, which is why it’s crucially important to select the correct seal for your application.
While leakage past a piston seal will affect its efficiency, the system fluid or gas remains contained in the system. With a rod seal, failure will allow external leakage, and it should be paired with an appropriate wiper and gland housing design to ensure correct operation.
How does a rod seal work?
Rod seals perform the difficult balancing act of creating a seal at both high and low pressure. This is often in combination with alternating high and low temperatures. As such, they need to leave an oil film, thin enough to return into the cylinder, after having passed an effective wiper seal.
When selecting a rod seal, it is important to define your area of application and provide carefully defined specifications. Martin’s Rubber can then give you recommendations for an appropriate rod seal to match your specific operating conditions.
Rod seal manufacturing techniques
Our rod seals can be CNC machined to bespoke sizes, including making adjustments away from original seal sizes to compensate for worn rod or gland conditions. Plus, they can help to restore the original performance of used equipment, as well as provide components for new build designs.
Their standard rod seals can be rapidly manufactured in a variety of different materials, depending on your application. They also stock standard products for immediate shipment if your requirements are particularly time critical.
