Office Equipment

Built on decades of knowhow, NSK bearings and bearing units use advanced technologies to support office equipment such as:

copiers and printers
banking and financial equipment
cash registers and ATMs
card readers, and more.

NSK’s unique technologies in areas such as materials, lubrication, and precision molding combine in a complete range of sophisticated bearings that meet environmental needs and save energy.

Office equipment requires high reliability, particularly in crucial banking and commercial facilities, and NSK bearings work behind the scenes to keep business running.

The greatest enemy of office equipment is electrostatic buildup. As a countermeasure, conductive bearings are used that incorporate conductive grease made from a mix of grease and conductive material. However, there is a concern that the conductive ability of the grease can degrade over time, so parts that need to be highly reliable also require a mechanical grounding function based on a flat plate spring or a brush.

NSK has launched a series of “ground-free” office equipment bearings by making use of special technologies that allow it to develop its greases in-house. In comparison with earlier products, these bearings offer a greatly extended conductive life. This development has not only extended the operational life of products, eliminating a mechanical grounding mechanism, it has also contributed to smaller, simpler devices.
