Temperature, pressure, speed, and media. These are just a few of the major factors you’ll need to consider when choosing a seal for rotary applications. Our nearly limitless combination of seal materials, energizers, and geometries – coupled with our consultative engineering approach – will help you address all of them, and create a solution that sets your designs apart. Here’s a look at how our Bal Seal® spring-energized seal performs under a variety of conditions.

V-ring seals manufacturers

A variety of spring energizer materials are available to meet chemical, temperature, and galvanic compatibility requirements

Hydraulicseal

The Bal Spring® canted coil spring exhibits a unique deflection and force behavior when it’s compressed. Unlike typical spring technologies, our spring exerts a near-constant force across the working deflection range, and its forces remain consistent – even in wide temperature ranges. It resists compression set, and its individual coils compensate for misalignment, tolerance variations, and surface irregularities.

The Bal Seal® spring-energized rotary seal gives you the ability to closely control frictional forces and optimize sealing effectiveness in a broad range of chemicals, temperatures, and pressures. Base jacket materials consist of polytetrafluoroethylene (PTFE), polyethylene (PE), polyetheretherketone (PEEK), and other specialty polymers. We combine these with advanced filler materials to enhance performance properties. Here’s a small sampling of the materials we’ve formulated for specific rotary application requirements.

Designs are provided as examples only. By precisely adjusting lip and heel geometries, energizer forces, and material formulations, we’ll create a solution that meets your unique rotary sealing requirements.

Excellent wear resistance in various gases, Low abrasion to dynamic surfaces and soft mating materials (aluminum, mild steel, brass, plastics), FDA compliant

Oilsealprofile

Designed for speeds of 750 ft./min, this seal employs an O-ring on the outer diameter. A canted coil spring energizer maintains a constant sealing force against the shaft.

When you’re sealing in rotary applications, speed is a primary consideration. Here’s a sampling of the thousands of profiles we’ve engineered for specific speed requirements.

This seal features a dynamic single contact lip that helps reduce friction and heat build-up at speeds up to 250 ft./min. Its design also allows for press-in mounting.

We produce our Bal Seal spring-energized seals for rotary applications in sizes ranging from 0.030 in. (.762 mm) to 120 in. (304.8 cm) inside diameter.

At the heart of almost every Bal Seal® rotary seal is an energizer that’s precision-engineered to promote even wear and longer seal service life. Choosing the right energizer – with the ideal combination of force, fit, and finish – is as critical to the success of your design as the seal material itself.

Designed for speeds up to 3000 ft./min, this seal features a metal locking ring that prevents rotation and promotes consistent sealing contact in thermal cycling conditions.

The custom-engineered Bal Seal® rotary shaft seal sets new standards for performance and reliability in rotary and oscillating applications. Precision machined from PTFE and other premium polymers, our seal combines innovative geometries with a wear-reducing spring energizer to extend the service life of the critical equipment you design.

For applications requiring an added level of protection, we can integrate an engineered metal locking ring into the Bal Seal® spring-energized seal design. The locking ring prevents rotation of the seal in the hardware, and it promotes consistent sealing contact under thermal cycling conditions. Backup devices made from PEEK and other materials can be designed to integrate with the seal jacket geometry, or they can be provided as separate parts.
