Bellows coupling BKXK 4048: 40mm diameter & 48mm length
The BKXK 4048 bellows coupling is the largest coupling in our bellows coupling portfolio. With stainless steel bellows and aluminium clamping hub, also for mounting on unmachined shafts. In addition to other high performance values, the speed of up to 10 Nm represents the peak value in the BKXK series.
With a diameter of 40 mm, the overall length is 48 mm. Please also note the many smaller versions. You can find examples of applications on the "Bellows couplings" page.
