Brass Gear Box Top

The gear box top seals the gearbox from above and often carries breathers, sensors or filler plugs. This gear is CNC machined from solid brass bar, delivering dense material structure and a premium appearance that cast parts cannot match. Free-cutting brass C36000 (H59/H62 equivalent) is our standard choice for its excellent machinability and corrosion resistance; copper C11000 is available when electrical or thermal conductivity matters. Material certificates accompany each batch. Sealing face flatness, dowel hole positions and threaded ports are machined to drawing in one setup where possible, so the cover mates with your gearbox housing without rework. Brass parts leave our machines with smooth, burr-free surfaces (Ra1.6 or finer as specified); polishing, nickel or chrome plating are available for decorative or anti-tarnish requirements. Every batch is inspected with CMM reports, thread gauges and surface roughness checks; small-batch and volume production are both welcome. Send your 2D drawing with tolerances or a 3D model - we reply with a quotation within 48 hours and can supply first samples within days thanks to brass's fast machining cycles.
