5. ETP Transmission
ETP Transmission AB is a specialist in power transmission, focusing on high-precision shaft-hub locking devices and servo couplings. When a motor needs to connect to a ETP provides the “component” that joins them—without gears or keyways, a wheel or a gear. Since its foundation in 1984, ETP has been a pioneer in mechanical engineering with hydraulic-mechanical locking bushings that deliver zero-backlash connections, significantly improving the precision of servo-driven machinery.
Key Products
- ETP Express Bushings: Hydraulic-mechanical bushings for the mounting of pulleys, sprockets and gears on shafts. A single screw torque creates massive hydraulic pressure for a secure concentric lock.
- ETP Classic Bushings “keyless” locking devices to replace traditional keyed shafts, eliminating the backlash and stress raisers keys create.
- Rapid Mounting Clamping Elements High Torque Transmission Systems for Heavy Industrial Drives
- Servo Couplings: Flexible & rigid couplings designed for precision motion control applications.
Key Features
- Zero Backlash: ETP bushings provide a true “friction lock.” Unlike keyways, there is no mechanical play (backlash), which is crucial for the repeatability of CNC machines and robotics.
- Ease of Installation: A standard hex key (torque wrench) is the only tool necessary to lock a component capable of transmitting thousands of Newton-meters of torque.
- Concentricity. Hydraulic expansion centers the hub perfectly on the shaft, reducing vibration and extending bearing and spindle life compared to eccentrically mounted keyed pulleys.
- Hydraulic-mechanical: uses a pressure medium (oil) confined behind a piston. Gives the holding ability of hydraulic systems without external pumps or hoses.
Achievements
- Niche Dominance: ETP is a dominant global player in the specific niche of shaft-hub locking for servo applications. They are the “go-to” for high-end motion control engineers.
- Industry Applications: Widely used in printing presses, packaging machines and woodworking equipment where timing and precision are paramount.
- Swedish Design: Evidence that Sweden is not only ahead in bearings but also in those particular “connective” components that tie the mechanical world together.
Feedback
Servo drive system designers are big fans of ETP. In many cases the ease of installation is important to them . A keyed shaft requires milling a keyway in the shaft and broaching one in the pulley . This is permanent . The ETP bushing permits the designer to adjust the timing of the pulley on the shaft by merely loosening a screw.
