HS6-37N1Z

Engineered for heavy-duty rotary applications, the HS6-37N1Z stands out in the HS Series by delivering nearly double the moment load capacity of the standard RK series within a similar footprint. This particular model features an internal gear design with a 33.133-inch bore and a 41.25-inch outside diameter, utilizing a rectangular cross-section that significantly boosts structural stiffness. Its internal architecture relies on a four-point contact gothic arch raceway, allowing a single row of balls to manage complex combinations of radial, axial, and high tilting moment loads simultaneously. For field engineers, this means achieving superior torque performance without the need for a bulkier housing, making it a go-to choice for space-constrained industrial turntables and lift cranes.

Beyond its raw load ratings, the HS6-37N1Z is built for long-term reliability in demanding environments. The integrated Nitrile (NBR) seals effectively lock out dust and debris, while the dual grease fittings (spaced 180° apart) simplify routine maintenance without requiring a full teardown. The internal gear teeth are precision-cut to an involute stub design with a 20° pressure angle, ensuring smooth engagement with mating pinions and reducing the risk of premature tooth wear under high-torque starts. Whether you're integrating this into a medium-duty excavator or a precision material handling system, the HS6-37N1Z provides that essential balance of a compact envelope and the "overbuilt" durability needed to handle sudden load shifts.
