Used in CNC machining centers requiring CAT40 tooling interface, this complete spindle cartridge assembly is stamped with manufacturer marking "BIG" (BIG Daishowa Seiki) and bears identifiers MC06271 and 529S06F014 machined into the lower body flange. Overall length measures approximately 32 inches based on tape measure visible in photos. The precision steel shaft incorporates multiple stepped bearing journals, a flanged mounting face at the base with a visible bolt-hole pattern for machine installation, and a CAT40 tool receiver at the upper end per operator confirmation. Oil and coolant service ports are visible on the body. A bagged hardware and tubing lot is packed alongside the cartridge in the original shipping crate.
BIG Daishowa Seiki is the originator and licensor of the BIG-PLUS dual-contact spindle system, supplying spindle cartridges to machining center builders worldwide under strict dimensional controls. The "BIG" stamp is consistent with BIG Daishowa factory manufacture or a licensed OEM spindle builder. The 529S06F014 identifier is consistent with a Japanese machine tool builder engineering drawing reference for HMC spindle cartridges. MC06271 is the primary stamped identifier on the lower body.
RPM rating, original machine compatibility, and coolant-through status are not confirmed from visible markings and should be verified before installation.
