HUBS
Aluminum Radial Clamping Hub (also available in steel and stainless steel)
- High tensile strength, low weight aerospace aluminum provides very low inertia for better system performance.
- Balancing Plug is positioned at a precise angle in the hub for balanced, high speed performance.
- Precision machined involutes (not a die cast).
- Zero backlash torque transmission is guaranteed.
- Only one clamping screw allows for fast installation.
- New EASY Clamp System prevents damage to hubs for easy shaft mounting and dismounting while compensating for tolerance differences between shaft and hub. (Available on select couplings.)
- Simply loosen the clamping screw against the pin to expand the clamping hub for easy shaft mounting and quick installation.

Steel Conical Bushings
|
Steel Conical Bushings (also available in aluminum for high torque, high speed applications up to 25,000 rpm)
- High clamping forces to insure safe transmission of torque and backlash free connection.
- Additional draw-off holes provide easy hub removal.
- Unique hub design offers shortest coupling length.
- Precision machined aluminum conical clamping ring insures a high speed balanced coupling up to 25,000 rpm at very high torque ranges.

Special Hub Designs
|
Special Hub Designs
- Flange mounted versions allow custom mounting configurations directly to the machine.
- All metal pluggable versions offer easy mounting in high temperature applications up to 300°C (572°F).
- Expanding cone clamping hub is ideal for hollow shaft assembly.

Brass Wire Press-Fit Connection
|
CONNECTION METHODS
Brass Wire Press-Fit Connection
- Mechanically formed between hub and multi-layered bellow for a strong zero backlash connection.
- No glue connection insures connection in high temperature, chemical sensitive applications.
|
Welded Connection
|
Welded Connection
- Micro plasma weld connection offers excellent weld consistency and even heat distribution resulting in high quality welds for a long lasting connection between hub and bellow.
- Ideal for high temperature applications where steel or stainless steel is required.
|
Bellows
|
TORQUE TRANSMISSION ELEMENTS
Bellows
- Guarantees a zero backlash torque transmission with extremely high torsional stiffness while maintaining flexibility for compensation of misalignment.
- Low mass moment of inertia for increased system performance.
- Maintenance free up to temperatures of 300°C (572°F).
- Depending upon torsional stiffness requirements, lateral spring rates and lengths, standard bellows are available in 2, 4 and 6 corrugations. For longer lengths, custom manufacturing is available.
|
Elastomers
|
Elastomers
- Elastomers vary in hardness values from 98 Shore A (red) for maximum dampening capabilities to 72 Shore D (white) where higher stiffness is required.
- Excellent electrical insulator to prevent the transfer of electrical fields.
- Involute shaped teeth provide easy plug-in assembly for long and durable life.
|
Torque Tubes
|
Torque Tubes
- Available in aluminum, steel or stainless depending upon torque and length requirements.
- The different materials can accommodate different stiffness requirements at various lengths.
