Machined Shafts and Rollers
Finish machined shafts and rollers delivered ready to fit
What Machined Shafts and Rollers Is and Who It Is For
These are forged shafts and rollers taken all the way through our CNC machining centre, so they arrive with journals, keyways, threads and flange faces finished. For pulp and paper mills in particular we supply shafts, rollers, canter heads, hubs, segments, axles and adapters as finished items rather than as blanks.
Key Benefits
- Arrives ready to fit, with no machining step left on your side
- One supplier is accountable for the finished dimension
- 5-axis machining handles flange faces and off axis features in one setup
- Heat treatment and machining sequenced correctly so the part stays straight

How It Compares
Buying a finished roller costs more than buying a blank, but it removes the machining queue, the transport leg between two suppliers and the argument about who caused a dimensional deviation.
Use Guide
- Send the finished drawing with the fits and surface finishes marked
- Say which features you will still machine so we leave the right stock
- Confirm any balancing requirement before production starts
