Spherical knobs Press Fit (Ball Knob)

These spherical knobs have a cone shaped hole to allow for easy press fit assembly on a h9 tolerance bar. Fit the handle onto slight chamfered shaft end and push as far as possible by hand or by means of a small press. Alternatively it is possible to tap the handle with a plastic or wooden mallet until firmly in place. In this case we strongly recommend to use a cloth or other suitable soft material over the product to avoid any surface damage.
