Zero-Max, Inc. designs and manufactures shaft couplings, SAE and non-SAE overhung load adaptors, adjustable speed drives, keyless shaft bushings, and other motion control and power transmission components.
Zero-backlash composite disc shaft couplings in single-disc, double-disc, floating shaft and custom models, rated for operation from -57 °C to 121 °C.
Metal disc shaft couplings for servo motor motion control, offered in 14 sizes in single and double disc models, with torque ratings from 0.5 to 250 Nm.
Overhung load adaptors (OHLA) for mobile hydraulic systems in SAE A through SAE F and non-SAE mounts, with input bores from 5/8 inch to 3 1/2 inch and cast iron housings.
Torq-Tender overload safety devices with built-in mechanical torque limiters, made of heat-treated steel, in end of shaft, shaft-to-shaft coupling and through shaft versions.
Right-angle 90° gear reducers with spiral bevel gears, in 1:1 and 2:1 ratios, two-way and three-way units, with speeds up to 2,000 RPM; standard and IP65-rated models.
Linear actuators that convert rotary motion into linear motion, in inch models with thrust up to 200 lb and metric models from 67 N to 887 N.
Mechanical adjustable speed drives that accept rotating input up to 2,000 RPM and allow output speed adjustment up to about a 4:1 ratio, in unidirectional and reversible versions.
Keyless shaft bushings that lock components to a shaft: ETP hydraulic bushings and Posi-Lok bushings that use mechanical tapered locking wedges.
