Trelleborg Sealing Solutions Spring Product Portfolio
Used to apply torque or store rotational energy and are typically found in single coil or double coil forms.
- Swing-down tailgates
- Garage doors
- Window shades
- Counterbalance mechanisms
- Coupling between concentric shafts
- Door closures
The most common spring type specified in the marketplace today and one of most efficient energy storage devices available. The usual form of compression spring is straight cylindrical from round wire. Other forms include conical, hourglass, barrel, square, ovate, rectangular or reduced ends, produced from round or flat wire.
- Electrical switches
- Measuring devices
- Brake systems
Designed to store energy and exert a required pull force when extended to a specific length, extension springs require a method of attachment as part of an assembly. Customized end configurations and orientations such as hooks, loops, and threaded inserts are a few of the options available.
- Automotive interiors
- Garage doors
- Washing machines
- Farm machinery
Constant Force Springs
These springs exert a constant force over the full range of motion and are produced as either motor type (drum take up) or extension type (strip end connection).
- Feeding systems
- Raise/lower mechanisms
- Surgical instruments
- Bed lift mechanisms
- MRI and X-ray machines
- Industrial staplers/guns
- HVAC fire dampers
- Retractable reels
Power springs store and release large amounts of rotational energy in the form of torque.
- Retractor mechanisms for electrical cords
- Starter pull cords
- Seat belts
Internal and external snap rings are offered to retain or locate components on shafts or in bores.
- Electric motors
Belleville Washer & Disc Springs
A Belleville washer is a type of non-flat washer with a slight conical shape or curvature, which gives the washer a spring characteristic.
- Actuation devices
- Bearing assemblies
- Clutch and brake mechanisms
- Oil and gas drilling equipment
Wave springs are often specified in place of conventional round wire compression springs. Generally, wave springs occupy 30-50% of the compressed height space of comparable round wire springs, offering more deflection with the same load specifications.
- Rotary unions
- Electrical connectors
- Drug delivery devices
Spring washers are an application-specific internally or externally slotted disc ring.
- Safety brakes/valves
- Machine tool clamping
- Vibration isolation
Spring Clips & Pins
Trelleborg Sealing Solutions offers a selection of common locking pins and custom designed stamped spring shapes.
- Tractor attachments
- Brake pads
- Sports bikes
- Lawn and garden equipment
Finger & Coiled Springs
These are unique spring designs with loading across the major length. Many designs are welded in rings with deflection occurring by compressing the spring radially between two portions of hardware.
- Mechanical locking
- Work holding and centering devices
- Electrical contacts
Stamped & Wire Form Parts
These are custom designed stamped or wire-form components which may perform a spring function.
- Electronic components
- Automotive and aerospace connectors
