R+W FK1 Microflex Coupling
R+W FK1 Microflex coupling with polyamide flex element and stainless steel hubs for compact precision feedback shafts.
Model overview
R+W FK1
R+W FK1 Microflex coupling with polyamide flex element and stainless steel hubs for compact precision feedback shafts.
Design and construction
Engineering characteristics
FK1 is a Microflex design combining a polyamide flexible element with stainless steel hubs. It is listed alongside MK miniature couplings for navigation but is a distinct Microflex product line within the R+W portfolio.
Selection guidance
Choosing and specifying
- Confirm envelope and bore against encoder or resolver shaft dimensions.
- Compare with MK metal bellows miniature models when higher torsional stiffness is required.
- Provide speed and torque duty for catalogue verification.
Applications
Typical use context
Encoder, resolver and light feedback shafts in automation, measurement and compact servo interfaces.
