Bearing Housing Seal Solutions by Polypac

Reliable Sealing for Rotating & Static Housings

Bearing Housing Seal is essential for protecting bearing assemblies from contaminants, lubricant loss, and premature wear. Polypac designs seals that balance low friction, tight retention, and long service life to maintain operational efficiency across pumps, gearboxes, motors, and industrial bearings. Our solutions reduce downtime, extend bearing life, and improve system reliability for OEMs and maintenance teams.

Advanced Materials & Custom Options

Polypac leverages decades of material expertise—starting with filled PTFE compounds (bronze, carbon, graphite, MoS2, glass) and extending to elastomers such as NBR, FKM, silicone, EPDM, and FFKM—to formulate Bearing Housing Seal products tailored to your specifications. With a 10,000+ m2 custom rubber ring and O-ring factory and 8,000 m2 production area, we provide scalable custom moulding, precision machining, and compound development to meet dimensional, chemical, and thermal requirements.

Engineered for Extreme Conditions

Whether exposed to high pressure hydraulics, aggressive fluids, abrasive particulates, or wide temperature swings, our Bearing Housing Seal designs survive harsh environments. Polypac combines advanced production and testing equipment with ongoing collaboration with universities and research institutes to validate performance under real-world stressors—ensuring low leakage, minimal extrusion, and sustained sealing force throughout service life.

FAQ:

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.

What does "AS568" mean?

AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.

How do I choose the right material for my sealing application?

Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.

Can I reuse a seal?

We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.
