Shaft Coupling Description
SERVOPLUS 45 GSPMF (GSP45MF20) - Hub (d = 20F7, Al Alloy) is a part designed for SIT SERVOPLUS bellows couplings. It is made of aluminium alloy.
SIT SERVOPLUS are all-metal, torsionally rigid bellows couplings with backlash-free torque transmission, designed specifically for servo motor drives where maximum positioning accuracy is required. They transmit torque through a durable stainless steel bellows element connected to metal hubs on both sides. GSPMF hubs are made of aluminum alloy and feature a finished bore with an F7 tolerance and a hole for a radial clamping screw.
Construction
- GSPMF hubs with a finished bore and a hole for a radial clamping screw
- Bellows element
Typical Applications
SIT SERVOPLUS bellows couplings with GSPM/GSPMF hubs and a GSPS bellows are designed specifically for drives controlled by servo motors, where in addition to torque transmission, maximum positioning accuracy and zero backlash are required.
They are used, for example, on the axes of CNC metalworking and woodworking machines, in robotics and manipulators, on packaging and printing machines, in instrumentation, measurement and automation technology, and on laser and cutting machines, as well as in other precision automated drives with closed-loop position control. They are also used in the food, chemical, paper, metalworking, and automotive industries.
Properties
- Torque transmission with maximum precision and zero backlash
- High torsional rigidity
- Low moment of inertia
- Excellent dynamic characteristics even at high speeds and during frequent load reversals
- Simple and quick installation
- Maintenance-free and wear-resistant
- Temperature resistance up to +300 °C
