About SPG

SPG Co., Ltd. is a South Korean precision geared motor and reducer specialist listed on KOSDAQ, presenting itself under the line "the power that moves Korea" and aiming to become the world’s leading company specialising in geared motors and precision reducers. Its robotics range is the reason for its place in this directory: the KSH strain wave gear for robot joints, the KSR cycloidal robot reducer, precision planetary gearheads including servo-grade planetary reducers, and the SDD actuator for robotics — an integrated joint drive that combines a high-torque motor with a low reduction ratio (generally 10:1 or less) without a high-ratio reducer, designed for integral construction, high precision and rigidity, smooth low-noise operation and a compact, lightweight structure.

Alongside the robotics line, SPG manufactures standard AC geared motors and a broad catalogue of geared and precision motors for factory automation, appliances and industrial equipment. The company supports the range with gear reducer selection tools, manuals and technical data downloads, and investor-relations disclosures published on its site, including 2024 revenue of KRW 416,334 million as displayed in its IR section. It states that it maintains a global sales organisation through domestic and overseas branches and agencies. For directory partners, SPG is a listed Korean source for robot reducers and joint actuators.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	7 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	9 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.

Claim this profile to unlock response record, directory tenure and peer endorsements. The full methodology — what each signal measures and how it is calculated — is published in the Trust Signals methodology, including a change log.
