Talk to the Engineering Team Behind Every ウォームギア減速機 We Ship

Standard catalogue specifications (NMRV, WP frame sizes 030–250) ship from existing stock within 7-10 working days. Custom configurations (special bronze grade, food-grade NSF H1 lubricant, ATEX explosion-proof, custom shaft profile) typically run 25-35 working days from order confirmation. Production batches above 100 units may require additional 5-10 days for component sequencing — confirmed at quote stage.

Yes. Single-unit and small-batch sample orders (1-5 units) are accepted at standard pricing for engineering evaluation. Sample lead time matches catalogue stock (7-10 working days) for standard specifications. We recommend sample units for first-time customers before committing to production volumes — the worm gear reducer must fit your application footprint and clearance.

Yes. Send the legacy code or nameplate photo to [email protected] with your application context. Our engineering team returns a verified cross-reference (matching frame, ratio, motor mount, output type) within 24-48 hours. We have working cross-reference tables for Sumitomo, Bonfiglioli, Nord SK, Mitsubishi SCWS/SHVW, Fenner, SEW, Motovario NMRV, and major Chinese WP variants.

Standard catalogue specifications carry ISO 9001:2015 manufacturing certification, individual unit test report (torque verification, no-load run, oil leak, dimensional inspection), and material traceability for the worm shaft and bronze wheel. Premium specifications add CE marking, RoHS / REACH compliance, ATEX explosion-proof rating (Zone 22 / Zone 2), and NSF H1 food-grade lubricant compliance. Marine specifications include salt-spray exposure rating and FPM elastomer seals. Specify required certifications at quote stage.

Standard payment terms are 30% advance with order confirmation, 70% balance against shipping documents (B/L copy). Letter of credit accepted for orders above USD 10,000. Shipping incoterms support EXW (factory), FOB Busan / FOB Incheon, CIF destination port, or DAP for Korean domestic and selected Asian destinations. EXW pricing default; other incoterms quoted on request with full freight breakdown.

Standard warranty is 12 months from shipment or 8,000 operating hours, whichever comes first, against defects in materials and workmanship. Premium specifications (UNICASE housing, CuAl10Fe5Ni5 bronze wheel, induction-hardened worm shaft) carry 18-month warranty with 12,000-hour duration. Warranty excludes lubricant breakdown, installation damage, overload above SF rating, and water ingress beyond seal specification. Documented oil-analysis records extend the warranty horizon by 25% on continuous-duty installations.
