FK1 | Micro-Flex Coupling

Radial clamping is achieved on the FK1 with two (ISO 4766) M2 set screws.
It has an operating temperature range of -35 to 90 °C (-31 to 194 °F) and a speed rating of up to 10.000 U/min.
These couplings are maintenance-free if the technical limits are not exceeded. Brief overloads up to 1.5 times the value specified are acceptable. This is a Polyamid coupling with stainless steel hubs. The standard bore diameter is 1.5 mm (other bore diameters upon request). The extended diameter can be reduced by using a flattened shaft. A further reduction of the ø to 4.5 mm can be reached by using a M2x1.5 set screw (Additional Charge).
