About Zero-Max

Zero-Max, Inc. is a US power-transmission and motion-control manufacturer based in Plymouth, Minnesota, founded in 1949 around a mechanical variable-speed drive whose name became the company brand. Its best-known products for robotics and automation are servo-rated flexible shaft couplings: the CD composite-disc line, introduced in 1989, and the ServoClass line, introduced in 1996, both designed for zero-backlash, high-torsional-stiffness positioning in servo-driven machines, alongside Control-Flex couplings for feedback devices and Schmidt couplings that handle large parallel shaft offsets. Beyond couplings, Zero-Max makes overhung load adaptors that protect hydraulic motors and pumps, adjustable speed drives, Crown right-angle gearboxes, Roh’Lix linear actuators, overload safety devices and torque limiters, phase-adjusting hubs, and ETP and Posi-Lok keyless shaft bushings.

The company sells worldwide through distributors and application engineers, with a Danish subsidiary serving Europe and a German division added in 2021, and lists applications across automation machines, packaging, printing and converting, CNC machine tools, materials handling, agriculture, forestry and wind turbines. For directory partners, Zero-Max is a precision mechanical-components source for integrators that need servo couplings, shaft-locking devices or overload protection engineered into a drivetrain.

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.
