GAMMA Seal | Rotary & Shaft Seals | Trelleborg

The GAMMA Seal is an axial rotary seal that excludes contamination, moisture and grease. It consists of an elastomer sealing lip contained in a metal carrier. This design copes with arduous static and dynamic conditions in mobile hydraulics and power transmission applications.

Features: Oscillating and SingleActing

Mechanical Face Seals | Rotary & Shaft Seals | Trelleborg

Mechanical Face Seals are a special form of mechanical seals. They are also known under other designations, such as lifetime seals, floating seals, duo cone seals, toric seals and heavy duty seals. There are two different types of Mechanical Face Seals: Type DO is the most common form that uses an O-Ring as a secondary sealing element. Type DF has an elastomer with a diamond-shaped cross section as a secondary sealing element instead of the O-Ring. To search for available articles, please use the Electronic Catalog.

Features: Rotary

Ø – Range Pressure Range Temp. range Velocity
45 – 750 mm 0.3 MPa -45°C +200°C 3 m/s
1,772 – 29.5 in 43.5 psi -50°F +390°F 10 ft/s

Radial Oil Seals | Rotary & Shaft Seals | Trelleborg

Radial Oil Seals consist of a single lip bonded to a metal support with a garter spring. There are many different variations of the Radial Oil Seal, both with and without an integral dust excluding lip. These dust lips can be positioned either within the seal width or beyond the seal base. A successful Radial Oil Seal runs with a thin film of fluid under the sealing lip. The film acts as a lubricant and allows a meniscus to form on the other side of the sealing lip. Radial Oil Seals can also include hydrodynamic aids, which create positive sealing by returning any oil leaking back into the system. For pressures above the recommended 0.05 MPa (7.3 psi) a metallic support heel can be used.

Features: Oscillating and Rotary

Ø – Range Pressure Range Temp. range Velocity

Sealing Cap | Rotary & Shaft Seals | Trelleborg

Sealing Caps consist of a metal cap which has been rubber coated. They are used to plug seal gaps or holes. They are often used as a substitute for sealing flanges and covers in gear manufacturing.

Features: Static

Ø – Range Pressure Range Temp. range Velocity

Shaft Repair Kit | Rotary & Shaft Seals | Trelleborg

Suitable for the repair of worn shafts or for original equipment manufacturing to avoid the need to harden the shaft. Shaft repair kits are thin-walled stainless steel sleeves which do not require any modification to the existing seal sizes. Tools for installation on the shaft are included in the kit.

Features: Helix, Oscillating, Rotary and Static

STEFA System 500/3000/5000 Cassette Seals | Trelleborg

The STEFA® System is a completely enclosed seal providing the functions of oil seal, wear sleeve and dust protection in one unit. It has been developed to meet the ever increasing requirements of long service life, high functional reliability, environmental safety and easy installation. STEFA® System 500 / 3000 / 5000 Cassette Seals are used in heavy duty vehicle axles, hubs and industrial gearboxes.

Features: Oscillating and SingleActing

Turcon® Roto Glyd Ring® | Aircraft Rotary Seals | Trelleborg

The double-acting Turcon® Roto Glyd Ring® is used to seal rods, axles, rotary swivels and steering units with rotary, helical or oscillating movement. The Turcon® Roto Glyd Ring® consists of a seal ring in high grade Turcon® material activated by an O-Ring as an elastic energising element. A large number of sizes are available for both inch and metric housings.

Features: Helix, Oscillating and Rotary

Ø – Range Pressure Range Temp. range Velocity
6 – 2,500 mm 30 MPa -45°C +200°C 2 m/s
0.236 – 98 in 4350 psi -50°F +390°F 6.5 ft/s

Turcon® Roto Variseal® | Rotary & Shaft Seals | Trelleborg

A single-acting sealing element comprised of a U-shaped Turcon® ring and metallic energizing finger spring. It offers low friction with no stick-slip, minimized break out force and high wear resistance. Its constrained flange eliminates potential seal rotation and it is resistant to most liquids and chemicals. Unlimited shelf life.

Features: Helix, Oscillating, Reciprocating, Rotary and SingleActing

Ø – Range Pressure Range Temp. range Velocity
5 – 3,300 mm S: 25 D: 20 MPa -70°C +300°C L: 15 R: 2 m/s
0.197 – 130 in S: 3,625 D: 2,900 psi -95°F +570°F L: 50 R: 6.5 ft/s

Turcon® Roto VL Seal® | Rotary & Shaft Seals | Trelleborg

Single-acting seal for rotary, turning and oscillating movements for pistons, rods and shafts in a wide range of machinery. The O-Ring activated L-shaped Turcon® or Zurcon® seal element gives optimized low frictional static and dynamic sealing performance. Offers high wear and chemical resistance depending on seal and O-Ring material. Installed in closed, standard O-Ring grooves.

Features: Helix, Oscillating, Rotary and SingleActing

Ø – Range Pressure Range Temp. range Velocity
6 – 2,600 mm 30 MPa -45°C +200°C 2 m/s
0. 236 – 102 in 4350 psi -50°F +390°F 6.5 ft/s

Turcon® Varilip® PDR | Aircraft Rotary Seals | Trelleborg

Turcon® Varilip® PDR (Performance, Durability, Reliability) rotary shaft seals are constructed from one or multiple Turcon® PTFE based sealing elements which are mechanically retained in a precision machined metal body. The metal body gives a robust static seal against the housing, preventing thermal cycling, while the Turcon® sealing element provides positive dynamic sealing on the shaft, leading to excellent performance at high rotary speeds. Characterized by low friction and stick-slip-free running, the seal reduces temperature generation, permits higher peripheral speeds and lowers power consumption. This results in a long-service life, with maximized mean time between planned maintenance and greater productivity.

Features: Oscillating and Rotary

Ø – Range Pressure Range Temp. range Velocity
6 – 170 mm 1 MPa -60°C +200°C 60 m/s
0.438 – 4.25 in 145 psi -75°F +390°F 197 ft/s

V-Ring® | Rotary & Shaft Seals | Trelleborg

The V-Ring® fits directly onto the shaft and seals axially against a counterface, such as shaft collar, thrust washer or bearing face. Its light lip pressure generates low friction.

Features: Oscillating, Rotary and SingleActing

Ø – Range Pressure Range Temp. range Velocity
3 – 11,500 mm — -40°C +200°C 12 m/s
