R+W SP3 Metal Bellows Coupling
R+W SP3 metal bellows coupling with external clamping ring for precision servo and spindle drives requiring low backlash.
Model overview
R+W SP3
R+W SP3 metal bellows coupling with external clamping ring for precision servo and spindle drives requiring low backlash.
Design and construction
Engineering characteristics
SP3 belongs to the R+W SP metal bellows series with an external clamping ring arrangement. The stainless steel bellows element provides angular compensation while maintaining torsional stiffness for encoder and servo positioning duty.
Selection guidance
Choosing and specifying
- Confirm torque duty and speed against R+W SP catalogue data for your bore.
- Compare with BK clamping-hub bellows models when envelope and mounting differ.
- Define shaft bore, keyway requirements and misalignment for quotation.
Applications
Typical use context
Servo motor connections, ball screw drives, test stands and machine tool auxiliary axes where metal bellows stiffness is required with external ring clamping.

Common questions
SP3 is a metal bellows coupling in the R+W SP series, distinguished by an external clamping ring mounting arrangement for precision rotating shaft connections.
SP3 is an SP-series metal bellows design with external clamping ring. BK models cover a broader platform of hub mounting styles including clamping hub, flange and hollow shaft variants.
No. SP3 is a flexible metal bellows coupling for torque transmission, not an overload protection device.
