Get Multiple Factory Quotes for Your Parts in 24 Hours
Connect with 800,000+ listed factories in Asia. Receive multiple quotes for your parts and manage production with speed and confidence.

Each profile shows equipment lists, QC staff count, production capacity, and product range for Falk gearboxes, reduction gearboxes, and custom assemblies used in industrial automation, robotics, and machine tools. Reducers built around a worm-and-wheel stage rather than helical or spur gearing are catalogued separately under worm gear components.
Those timeline stretches are the real cost. Factory profiles display actual equipment lists including Gleason, Klingelnberg, or Mitsubishi grinding machines that indicate serious capability for holding ±0.005 to 0.01 mm tolerances on gear teeth and shafts.
Most requests for quotes (RFQs) receive at least eight responses within a day. Since the pricing is directly from the factory, there are no extra charges or markups from middlemen. But lead times vary significantly between factories with in-house heat treatment and those that outsource it. NDAs and a dedicated English-speaking account manager are provided at no cost.
If your gear teeth need DIN 6 accuracy or better, the equipment list matters more than the quote. Look for shops with temperature-controlled grinding rooms at 20°C ±1°C and in-house heat treatment facilities to avoid the 2-3 week delays that come with outsourced carburizing. Contact factories directly through their listings to discuss gear teeth tolerances, shaft runout specifications, and heat treatment requirements for gear reducers.

Choose factories with in-house carburizing and heat treatment facilities to eliminate the 2-3 week outsourcing delay. Ask for timeline breakdowns by operation (hobbing, heat treat, grinding) to identify which shops can actually deliver in 10-12 weeks instead of 16.
Inconsistent furnace atmosphere control and inadequate stress relief during carburizing cause warping that pushes dimensions beyond ±0.01 mm. Require batch traceability with furnace logs, hardness testing at multiple points per batch, and case depth measurements at 0.8-1.2 mm with microstructure photos.
Once you land on a gear reducer parts manufacturer in the directory, listed only after a general verification step, you contact that factory directly rather than going through Haizol as a middleman. Ask about in-house carburizing capability, case depth, or CMM tooth geometry inspection when you reach out, since those are things the factory confirms with you, not something checked at listing. Replies typically arrive within a day. For buyers who'd rather not message suppliers individually, Haizol's account manager can put the same RFQ in front of several factories simultaneously, free of charge.
Request inspection reports from recent orders showing CMM measurements on tooth geometry and contact pattern analysis with actual measured data. Ask which grinding machines the factory uses and whether they maintain temperature-controlled grinding rooms at 20°C ±1°C for consistent gear reducer output.
Include CAD files with gear tooth geometry, material grade (20CrMnTi or 42CrMo), surface hardness (HRC 55-62), and runout limits at ±0.01 mm or tighter. State annual volume and required certifications (ISO 9001 baseline, IATF 16949 for automotive) upfront to receive capability-matched quotes for reduction gearbox and Falk gearbox compatible components.
