Excellence in Motion and Control

The NSK Group is one of the world's leading manufacturers of motion and control products. With over 90 years of experience, NSK achieves sales over $7.2 billion, employs over 29,400 staff members and operates 64 ISO-certified manufacturing facilities worldwide. NSK linear motion products can be found in many applications within the automotive, semiconductor, food and beverage, medical, machine tool, and packaging industries. NSK is regarded as the world's leading manufacturer of precision ground ball screws and offers a full array of components and integrated assemblies for any challenging application.

NSK's U.S. manufacturing facilities, combined with Steven Engineering's contract manufacturing capabilities, provide flexibility to quickly respond to your needs and deliver unsurpassed quality, performance and reliability.

NSK Robot Modules™ are complete multi-axis, high-precision linear systems. High-quality linear drives, ball screws and NSK Monocarrier™ ensure a high level of mechanical reliability with an ergonomic design, enclosed in an aluminum housing.

NSK Monocarriers™ are a light-weight, single-axis actuator that embodies the technology NSK has accumulated over the years, with an all-in-one structure integrating a ball screw, linear guide, and support bearing. NSK monocarriers are suitable for a wide range of applications, including clean environments. NSK offers a quick-ship program for selected sizes of its MCM series for customers interested in purchasing smaller volumes for quick turnaround needs.

NSK Direct Drive Megatorque™ Motors are perfect for high-precision applications where size, weight, stiffness, and positioning are important. They are a great solution for many rotary applications such as semiconductor manufacturing and high-speed robot arms.

NSK Linear Guides incorporate production technologies that ensure the highest precision and quality, resulting in high-load capability and excellent dust-resistant performance to meet the needs of a variety of industries. Optional K1™ Lubrication Units self-lubricate the rails, ensuring longer life and maintenance-free operation.

NSK's New NS/NH Series Linear Rails change the linear rail game completely. These new designs increase load ratings over 30% and double the life of tradition Size 15 - 65 rails. The new design also increases smoothness, decreases noise and increases speed.

NSK Ball Screws were developed through cutting-edge tribology (friction control technology). NSK manufactures the largest volume in the world with its outstanding production and quality control techniques. They offer a complete selection of ball screws, from miniature to ultra-large sizes, for machine tools, injection molding machines and general machinery, as well as special environment usage in semiconductor and LCD production equipment. Standard stock of NSK's Compact FA Series is manufactured domestically and available for quick-ship to accommodate fast delivery.
