Item description/product images

DescriptionMaterial:Aluminium.Version:Bright.Note:Backlash-free, torsionally stiff, flexurally elastic and maintenance-free all-metal coupling for the transmission of angularly synchronous rotary movements. The innovative slot structure enables very good axial, radial and angular flexibility with low restoring forces. Best suited for servomotors. With clamp hub for shaft fastening.Temperature range:-50 °C to +150 °C.Assembly:The beam couplings have a H7 tolerance. The recommended clearance tolerance is 0.02 - 0.05 mm. This tolerance and lubricating the shaft journals aids assembly and removal.On request:Desired hub holes D1 and D2 seperately with tolerance class or tolerance zone.
DIN 6885 keyway.
