NSK's special environment ball bearings, ball screws and linear guides are optimal for applications in operating environments that are too severe for standard products. The SPACEA™ Series has a wide array of product variation applicable to special environments such as vacuum, clean, corrosive, high-temperature, dust or water contaminated, and non-magnetic requirements. In demanding operating environments, these bearings will meet your high quality and high performance standards. The special environment range utilizes advanced materials, lubricants and surface treatment technologies for special operating conditions.
Deep groove ball bearings are the current focus of the rolling element SPACEA™ Series. These are designed for use in a wide variety of special environments including:

Lubricated with NSK’s original oil-impregnated material, Molded-Oil™, and are suitable for corrosive and dust-contaminated environments.
A special fluororesin for outer/inner rings, balls & cages equipped to meet a broad range of light load applications in water, alkali & strong acid environments.
Combining ceramic balls and fluororesin self-lubricating cages, are suitable for corrsoive environments from normal atmosphere up to vacuum.
Stainless steel bearing specially designed for high temperature and water-splash environments.
With self-llubricating fluororesin cages, these bearings are suitable for corrosive environments & non-magnetic requirement from normal atmosphere up to vacuum.
Nickel coating on the outer & inner rings to enhance corrosion resistance & durability.
Ulitizing oxide-based or silicon nitrate-based ceramics, these bearings are designed for alkali and weak acid environments.
Highest corrosion resistance among ceramics - designed for strong acid, strong alkali and corrosive gas environments.
More durable than stainless steel ball bearings - designed for strong acid, strong alkali and corrosive gas environments.
