Request QuoteV-belt sheaves SPZ/SPA/SPB/SPC, classical A/B/C/D, taper-lock or QD bores. Wide-belt and combination configurations.
Request QuoteInline and right-angle planetary reducers. Servo-grade precision, <3 arcmin backlash, slewing and high-torque ranges.
विनिर्देश देखेंHTD, GT2, T5/T10, AT5/AT10 and classical L/H/XH profiles. Aluminum and steel, stock and custom bores with keyway.
Request QuoteOne-piece, two-piece, set-screw, clamp-style and double-split. 1018 carbon steel, 303/316 stainless and aluminum.
Request QuoteOutside the standard catalogue? Send drawing or sample — we manufacture to specification with full material certificates.
Send DrawingIncluding these five details upfront lets the engineering team return a sized worm gear reducer specification in the first reply — instead of a back-and-forth requesting more information.
What does the worm gear reducer drive? Conveyor, mixer, indexer, lift, agitator, slewing arm — be specific about the driven equipment type and any shock characteristics.
Application power in kW (or HP) and target output speed in rpm — or alternatively the gear ratio i if known. Input motor speed if non-standard.
Hours per day, ambient temperature range, humidity / dust / chemical exposure. Indoor or outdoor mounting; vibration source nearby.
Foot mount, flange mount, hollow shaft, IEC motor frame size — or send a drawing with the existing footprint and output shaft details.
First-article sample, pilot batch (5-20 units), or production order (50+). Required delivery date and destination port for shipping cost estimate.
Answers to the highest-frequency pre-purchase questions — covers lead time, samples, customisation, certification, payment and warranty.
Six commitments built into every worm gear reducer order. These are operational guarantees, not marketing copy — call out any failure to honour them and we re-engineer the spec at no charge.
Application briefs, drawings and specifications stay between your company and our engineering desk. We do not share inquiries with third parties; aligns with GDPR and Korean PIPA.
Every worm gear reducer ships with individual test certificate. Material traceability for worm shaft alloy and bronze wheel grade documented per unit serial number.
Quote requests answered with sized specification, frame & ratio recommendation, and CAD drawing within two business days from a real engineer — not a sales chatbot.
Production at the Sandan-ro campus in the Banwol-Sihwa industrial complex. Vertical manufacturing — gear cutting, heat treatment, assembly, test rigs — all under one roof.
We don't sign you up to mailing lists, we don't follow up unsolicited, and we don't share your contact with sales partners. Email when you need us; silence when you don't.
Field issues, oil-analysis interpretation, retrofit cross-reference — covered within the engineering desk for the lifetime of the unit. No additional service contracts required.
