Zero-Max announced expansion of its Posi-Lok keyless shaft bushings product line. These shaft locking devices rigidly and reliably secure shaft mounted components into position. They are a superior shaft-hub locking solution eliminating keyways which can weaken or cause excess wear to shaft components.

The expanded Posi-Lok product line includes nine different models in a wide range of sizes. Now available are more model and size options to handle different torque requirements and mounting configurations for unique motion control applications. Also available are more material choices to meet specific application requirements such as corrosion protection as well as environmental considerations. Most models are available to ship from stock. 

All Posi-Lok models easily slide onto a shaft and provide reliable, zero-backlash performance. They provide excellent concentricity with minimal radial and axial runout. Their field-proven mechanical design does not require keyways thereby reducing machining costs. 

Included among the new models and sizes are stainless steel models for use in highly corrosive applications such as food processing, chemical processing and others that operate in harsh environments. Also available are electroless nickel plated models and standard alloy steel models.
