Castings and forgings
Housings · hubs · bearing seats · machined blanks
Cast and forged blanks machined on the same floor that finishes our own parts: bearing housings, gearbox casings, hubs and rings. We source the casting or forging from a foundry or forge we have used before, verify the grade against the mill certificate, and machine it to your drawing. Stress relief sits between roughing and finishing, so the bore does not close up after the part leaves us.
