Turcon® Roto VL Seal® From Trelleborg Sealing Solutions Fits Into Smaller Spaces

FT. WAYNE, IN--(Marketwire - February 24, 2009) - Trelleborg Sealing Solutions, a worldwide leading supplier of high-quality sealing and bearing systems, launches its new Turcon® Roto VL Seal®. The seal's uniquely compact form makes it ideal for specification in dynamic applications where there is limited space or for fitment into standard O-Ring grooves. It is primarily intended for constant service in demanding situations where there are rotary, swiveling or helical movements at medium to high system pressure.

The seal is developed from the proven Turcon® VL Seal®, and like this consists of an L-shaped Turcon® seal that is energized by a static O-Ring. The new Turcon® Roto VL Seal® is a non-symmetric single-acting seal designed to optimize the sealing performance under various pressure and surface velocity conditions.

"A unique feature of the new Turcon® Roto VL Seal® is that, due to decreased hardware requirements, it can be fit into much smaller spaces than traditional rotary seals," says Joe Woods, Fluid Power Segment Manager for Trelleborg Sealing Solutions Americas. "It is also an excellent choice where standard O-Ring housing grooves are preferred."

Some applications where the new Turcon® Roto VL Seal® would be found are: rolling mills, machine tools, hydraulic swivels, injection molding machines, valve spindles, food processing (blenders and mixers), hydraulic steering units, forestry machines and cranes, rotators for handling devices, vane actuators/motors, hydraulic motors, hydraulic pumps, propeller thrusters and ROVs (remotely operated vehicles).

Operating Conditions:

-- Movement: Rotary, intermittent or oscillating service. Velocity to
   2 m/s/ 6.5 feet/s
-- Pressure: Up to 30MPa / 4,350psi (40 MPa / 5,800 psi for short
   durations or when static)
-- Temperature:
   -- Turcon® materials: -40°C / -40°F to +120°C /+248°F (+200°C / +392°F
      static) according to O-Ring material.
   -- Zurcon® Z52: -40°C / -40°F to +80°C / +176°F (+100°C / +212°F
      short durations or static) according to O-Ring material
   -- Zurcon® Z80: -40°C / -40°F to +60°C / +140°F (+80°C / +176°F short
      durations or static) according to O-Ring material
-- Media: Hydraulic fluids, water-based fluids, air and gases depending on
   seal material
