COS Technology supply a wide range of hydraulic seals in both light duty and heavy duty applications. This range includes rod seals, piston seals, wiper seals and guide rings. The range of seals can cope with:-

• Wide temperature fluctuations
• Irregular duty cycles and maintenance
• High lateral forces and deflections
• Very dirty conditions
• High system pressures and pressure peaks

Sealing components are used to retain the hydraulic medium securely inside a hydraulic system. A defined moistening of the counter surface with lubricating medium is desirable when the required service life is taken into account. A sealing component is referred to in this regard as leaky if the hydraulic medium is visible from the outside in the form of dripping leakage.

The ubiquitous rotary shaft seal is often taken for granted, however careful consideration of operating paramaters at the design stage can often lead to longer life and optimised performance.

Several features need to be factored into seal design:-

• Is an external static seal needed?
• Is a dust lip to prevent ingress of foreign matter required?
• What media are to be sealed?
• Are the seal and tension spring materials compatible with this media
• Circumferential speed
• Upper and lower temperature limits
• Will the seal be pressurised?
• Are there vibrations, or heavy loads?
• What shaft and housing sizes are readily available?

All of these factors affect seal choice, to ensure leak tightness, reliability, compatibility, low friction and easy fitting.

So whether you are designing a new transmission unit or repairing a gearbox, give us a call and we can take the guesswork out of your seal selection. E mail at sales@chinaoilseals.com

For really arduous applications we have a whole range cassette seals, which perform well, even in the most difficult environments

The O-ring is the most common type of fluid seal.  An O-ring’s simple design lends itself to a multitude of sealing uses, including static, reciprocal, oscillating, and dynamic applications at low speed and pressure.  In elevated operating pressure environments, addition of a backup ring will greatly increase the extrusion resistance of an O-ring.

The most basic shape of an O-ring is a simple circular sealing torus, usually made from an elastomeric material. Beyond the standard O-ring, All Seals can supply more advanced sealing designs such as Quad Rings, which are specially designed for low pressure sealing.  All Seals also offers O-rings in advanced materials such as Viton®, Viton Extreme®, and Teflon®.

All Seals stocks over 200 million O-rings in 13,000 different size and material combinations.
