OK coupling, installation and removal kits - SKF TMHK
When you use OK couplings to connect shafts, you benefit from our powerful SKF pressure oil process.
When assembling the OK coupling, a thin inner sleeve with a conical outer diameter slides onto the shaft.
A thick outer sleeve with a matching conical inner surface fits onto the inner sleeve.
-Oil is then injected between the sleeves.
-An integrated oil pressure press drives the outer sleeve onto the cone of the inner sleeve.
-Once the outer sleeve has reached its final position, a press fit is created – as if the outer sleeve had been heated and shrunk.
-However, no heat is required, and the coupling can be removed just as easily as it was installed.
