CNC Machined Gearbox Components for Industrial Teams
Industrial teams in San Jose need gearbox components with precise bearing fits, concentric bores, and hardened surfaces. We machine 4140 steel, 8620, and aluminum gear housings, shafts, and bearing caps to ±0.0005" on critical fits. CMM inspection and material certs on every order.
Transmission Materials
4140 steel, 8620 case-hardening steel, and aluminum with mill certs.
Bearing Fit Precision
±0.0005" on bearing bores and shaft journal diameters.
Full Documentation
CMM reports, material certs, and heat treat records.
Silicon Valley's Growing Industrial Equipment Ecosystem
San Jose and the broader South Bay support a surprising depth of industrial equipment manufacturing. Curtiss-Wright's EMD division in Rancho Cordova builds high-performance pumps and valves for nuclear and defense applications, while Pentair's San Jose operations produce water treatment and fluid handling systems. Bloom Energy in nearby Sunnyvale manufactures solid-oxide fuel cell power platforms, and Cypress Envirosystems (also Sunnyvale) develops retrofit automation for industrial HVAC and compressed-air systems.
RivCut machines precision components for Silicon Valley's industrial equipment builders — valve bodies, pump housings, gearbox shafts, and compressor fittings — with the tight tolerances and fast turnarounds that OEM production schedules demand.

A South Bay pump manufacturer needed hydraulic manifold blocks with cross-drilled passages, O-ring gland grooves, and precise port thread depths for high-pressure fluid systems. Teams near companies like Pentair trust this kind of precision and documentation rigor.
Every part shipped with full documentation:
- CMM dimensional report — port locations and passage alignment verified
- Material cert with heat lot and ASTM B209 compliance
- Surface finish verification on sealing surfaces
- Thread gauge verification on all ported connections
What San Jose Industrial Equipment Buyers Should Know
Silicon Valley's industrial equipment makers often need quick-turn prototypes of valve bodies or pump housings in exotic alloys like Hastelloy or Monel
Verify your CNC shop can source and machine these materials before committing to a timeline.
Water treatment and fluid-handling equipment for Bay Area utilities must meet NSF/ANSI 61 or 372 standards
Ensure your machining partner understands lead-free alloy requirements and can provide compliant material certifications.
Fuel cell and clean-energy equipment components often require surface finishes below 32 Ra and tight flatness on sealing surfaces
Specify finish requirements upfront to avoid secondary grinding operations that add cost and lead time.
