Creating the perfect hollow shaft connection in gearbox applications isn’t easy. You need to maintain strict dimensional tolerances between the solid and hollow shafts—a process that requires precise, yet costly machining.

Achieving a perfect hollow shaft connection requires a lot of precision machining. The solid shaft must be manufactured to exacting dimensional tolerances (0.025 mm) before being inserted into the equally close tolerance hollow bore of the gearbox. Gearboxes and shaft interfaces that don’t have these tight tolerances will often suffer from diminished torque transmission.
