Integrated Mechatronic Systems

Accelerate product development, simplify procurement and speed up production using NSK’s renowned mechatronics expertise to design a pre-configured, pre-built and fully tested motion system. Integrated systems utilize NSK’s core products and technology to ensure the high quality synonymous to the NSK brand, as well as locally-based Application Engineers to work closely with customers from design and testing, to installation and maintenance.

The NSK Difference

NSK is leading the charge to enable our customers move to a smart factory, or simply, operate smarter to increase over-all equipment efficiency (OEE). We help customers make the shift from preventive to predictive, reduce total cost of ownership, and increase their competitive advantage.

Using condition monitoring systems such as the NSK BD2 and Acous Navi™ technology, we help customers diagnose bearings based on bearing pulse vibration data to determine degree of failure, failure rate and ultimately, remaining life.

In addition to NSK’s proprietary technology, NSK’s Application Engineers and Americas Technical Center (ATC) also execute comprehensive root cause analyses of premature bearing, linear guide or ball screw failures in industrial automation applications. We recommend countermeasures or new product specifications that can significantly reduce wear or contamination, boost performance, and improve life.

Case Study: Nut Runner System for Transmission Case Assembly

An automotive OEM required an automated nut runner system moving in X, Y or Z axis, to tighten nuts individually within a predefined travel parameter set.

Pain Point

The OEM posed a tough challenge for a transmission case assembly process: zero failure and zero downtime.

Three-axis Robot Module Nut Runner System

Solution

NSK proposed a three-axis Robot module designed with high stiffness to accommodate the heavy load of the customer’s nut runner process. Not only did the NSK Robot Module’s very precise, controlled motion reduce the deformation and oil leak from the transmission case, the efficient connection points for XYZ stages also ensured simple installation and minimal set-up time.

Equipped with K1 lubrication units for maintenance-free operation up to 5 years or 10,000 km travel, the NSK Robot Module reduced downtime and increased OEE for the nut runner line.

Since the customer relied on NSK to deliver a fully assembled system, design validation for loaded life, rigidity and repeatability, as well as quality testing were all done prior to shipping each assembled XYZ unit. Once again, NSK delivers a zero-failure rate performance!
