About PMI (Yin Tai Technology)

PMI — Precision Motion Industries, Inc. — is a Taiwanese manufacturer of precision transmission components, founded in 1990 and based in Taichung. The company, which trades under the PMI Linear Motion Systems name, develops and manufactures ball screws, precision ball screw splines, linear guideways, ball splines, actuators and cross roller bearings — the key components that convert rotary motion into precise linear movement inside machine tools and automated equipment. Its official site states that its products are supplied to machine tools, electrical discharge machines, wire-cutting machines, plastic injection moulding machines, semiconductor equipment, precision positioning systems and other machinery, and that the company has invested heavily in process improvement, product accuracy and quality.

PMI has held ISO 9001, ISO 14001, ISO 45001 and ISO 50001 certifications and promotes RoHS-compliant, low-pollution production. In 2025 the company announced its entry into the humanoid robot market as a supplier of key components, extending its precision drivetrain range toward robotics applications. With plants in Taiwan’s Feng Chou high-tech industrial park area and a global locations network listed on its site, PMI presents itself as a candidate to become the first-choice global brand for precision transmission components. For directory partners, PMI is a long-established Taiwanese source of the screws, splines and guideways that sit inside precision machines and, increasingly, robot joints and axes.

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	8 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.
