Sealing, damping, and protection: functions and selection parameters

Sealing, damping, and protection systems perform three distinct but often complementary functions: retaining lubricants and excluding contaminants, isolating vibrations between machinery and supporting structures, and protecting surfaces against abrasive wear. The choice of the right product depends on the type of movement to be sealed or isolated, the direction of dynamic loads, and the required abrasion resistance based on the operating cycle. JFK Group distributes and supplies the complete range: every product is selected, inspected, and backed by technical support.

SELECTION GUIDE

Things to consider before making a choice

The choice between the three product families depends on the main function required: containing a fluid, isolating a vibration, or protecting a surface from wear. In some cases, requirements overlap, for example when both damping and abrasion resistance are needed.

For sealing applications, the choice of elastomer material depends on the operating temperature and chemical compatibility with the fluid in contact. For vibration isolation, the predominant working direction and load magnitude are key factors. For abrasion protection, the choice between polyurethane materials depends on the required hardness, compressibility, and weather resistance.

Solutions

Find the right solution for your application

Do you need to retain a lubricant or prevent contaminants from entering?

Sealing rings are designed for rotating shafts; O-rings are used in high-pressure static and dynamic applications; NILOS rings are mounted directly on bearings to protect them from dust and external contaminants.

JFK sealing systems

Do you need to isolate vibrations between machinery and the supporting structure?

Rubber-to-metal vibration isolators absorb shocks and isolate vibrations: cylindrical silent blocks for compact, multidirectional operation; rubber buffers for floor mounting and leveling; and conical mounts for maximum deflection and low natural frequency.

JFK vibration isolators

Do you have surfaces subject to heavy abrasive wear?

Vulkollan®, Elastopal®, and Cellasto® polyurethane materials offer superior abrasion resistance compared with standard rubber, for wheels, coatings, scrapers, and components subject to continuous wear. Damping and abrasion protection

JFK damping and abrasion protection

Do you have surfaces subject to heavy abrasive wear?

Do you need damping with high compressibility?

When high compressibility combined with low permanent set is required—for end-stop buffers and foundations for vibrating machinery—polyurethane materials such as Cellasto® offer superior damping performance compared with traditional vibration isolators.
