Short and good

The cou­pling series KP with 4‑corrugated bel­lows and two radi­al clamp­ing hubs, is a ver­sion with short­er over­all length in the Jakob met­al bel­lows cou­pling range. This makes it par­tic­u­lar­ly suit­able for appli­ca­tions with min­i­mal shaft spac­ing and lim­it­ed instal­la­tion con­di­tions. In addi­tion, the very high tor­sion­al rigid­i­ty val­ues ​​and the easy-to-install clamp­ing hub design are worth men­tion­ing. A low moment of iner­tia and good val­ues ​​for the per­mis­si­ble shaft mis­align­ments and restor­ing forces com­plete the pos­i­tive picture.

The mul­ti-lay­er, made of cer­ti­fied stain­less steel, met­al bel­lows is char­ac­ter­ized on the one hand by its high tor­sion­al rigid­i­ty and on the oth­er by the com­pen­sa­tion of axi­al, radi­al and lat­er­al shaft off­sets. Due to the short­ened design and the result­ing weight sav­ings, there are oth­er advan­tages such as low­er moments of inertia.

The clamp­ing hub is made of high-strength alu­minum to achieve the low­est pos­si­ble moment of iner­tia. The hubs are equipped with the inno­v­a­tive and ser­vice-friend­ly Easy-Clamp-Sys­tem. It guar­an­tees a sim­ple, with enough fit­ting tol­er­ance pro­vid­ed post­pone­ment. A sin­gle, radi­al­ly acces­si­ble screw per hub pro­vides the for torque trans­mis­sion nec­es­sary pre­load force. Thanks to this sim­ple, but very reli­able con­nec­tion, the cou­plings can be mount­ed in just a few easy steps, even in dif­fi­cult instal­la­tion con­di­tions. The bel­lows-hub con­nec­tion is made by the opti­mal and back­lash-free brass-wire press-fit method. In con­trast to adhe­sive joints, this join­ing process is absolute­ly unlim­it­ed for crit­i­cal oper­at­ing con­di­tions (-40 ° C to + 200 ° C, chem­i­cals) and the trans­mis­sion torque of each indi­vid­ual bel­lows lay­er is safe­ly intro­duced into the hub.

The KP series is avail­able for nom­i­nal torques from 25 to 900 Nm with bore diam­e­ters from 10 to 75 mm.
