When we get a new set rollers it comes to us without the spacers and bearings attached. What's the best way to press the bearings onto the rollers?
Thanks.
Thanks.
True, using a hammer is NOT the best method. I would love to work with all the right tools and adequate time to do so. The facts are some large sheetfed shops are under tooled and under staffed. At 2 :00 A.M. corners are sometimes cut.
All rollers should come with bearings press ready. The only bearings not installed are meter & water forms due to the gears not being attached.
I would disregard CKL's reply completely. Hitting the bearing will damage the race. Bearings are precision built with very tight tolerances. Installation should be performed using a hydraulic or other mechanical press with pressure applied to only the inner part of the bearing. Lubricate the shaft of the roller and the bearing before continuing with the installation. Hitting the bearing will shorten its life by more than half and will cause minute movements in the way the roller will spin maybe causing uneven printing specially light screens. Take it to a machine shop if you don't have the right tools.
