Rotary Glyd Ring

Product Introduction

ROTARY gyld seals - ELASTOMER ENERGIZED Description:

Rotary gyld seal is used to seal rods, shafts, axles, bores, rotary transmission leadthroughs, journals, swivels etc. with rotary or oscillating movement. The seal is double-acting and can be exposed to pressure from one, or from both sides.It consists of a seal ring of ptfe material and is activated by an O-Ring as an elastic energizing element. The contact surface profile of the seal ring is specially designed for use under high pressures and at low sliding speeds.

Depending on the profile cross-section of the seal, the contact surface has one or two continuous machined grooves. These have the following functions:

- Improved seal efficiency by increasing the specific surface load pressure against the sealed surface

- Formation of lubricant reservoir and reduction in friction.

Product Details

ROTARY gyld seals double acting O-Ring energized seal designed for rotating, oscillating and helically moving pistons, rods and shafts. Installed in grooves to ISO 7425. Available in single acting version for higher rotating speeds.

In order to improve the pressure activation of the O-Ring, the rotary gyld seal has notched end faces as standard. The rear face which holds the O-Ring has a concave form. This increases the contact surface and shall prevent the seal from turning with the rotating surface.

Advantages

- Available for internal and external sealing applications.

- Low friction.

- Stick-slip-free starting, no sticking.

- High abrasion resistance and dimensional stability.

- Simple groove design, small groove dimensions.

- Lubricant reservoir.

- Available in all sizes up to 2700 mm diameter (to 2600 mm for rod seals).

Installation instructions

The following points should be observed before installation of the seals:

- Check whether housing or rod has a lead-in chamfer; if not, use an installation sleeve

- Deburr and chamfer or round sharp edges, cover the tips of any screw threads

- Remove machining residues such as chips, dirt and other foreign particles and carefully clean all parts

- The seals can be installed more easily if they are greased or oiled. Attention must be paid to the compatibility of the seal materials with these lubricants. Use only grease without solid additives (e.g. molybdenum disulfide or zinc sulfide)

- Do not use installation tools with sharp edges
