For Special Environments (SPACEA™ Series)

The SPACEA Series of bearings for clean-room applications aim for zero emissions. By taking advantage of proprietary technologies, applications for which the SPACEA Series of bearings can be used has been expanded to include high-temperature operating conditions in normal atmosphere and vacuum environments.

High corrosion-resistant bearings are applicable in corrosive environments such as water, weak acid and alkali, and strong acid and reactive gas. High corrosion-resistant bearings include stainless steel bearings, Molded-Oil bearings, and corrosion-resistant coated bearings (Nickel coating) for water environments; ceramic bearings and ESA bearings for weak acid and alkali environments; and ceramic bearings and the Aqua-Bearing for strong acid and reactive gas environments.

High Corrosion-Resistant, Non-Magnetic Stainless Steel ESA Bearings

Bearings are provided with ample lubrication for extended periods from oil seeping with a polyolefin resin for excellent performance in water and dust contaminated environments.

These rolling bearings are provided with self-lubricating molded oil, which provides ample lubrication from oil seeping from a polyolefin resin These bearings provide excellent performance in dust-contaminated environments. A stainless steel series of this bearing is also available for environments where there is heavy exposure to water contamination.

Molded-Oil™ Bearings


This rolling bearing, which is packed with fluorine grease for high-temperature operating conditions and uses MoS2 solid lubricant, can be used in high-temperature environments up to 400 °C.

High-Temperature KPM Grease-Packed Bearings


Bearings for non-magnetic requirement are classified into non-magnetic (relative permeability 1.01 or less) bearings and completely non-magnetic (relative permeability 1.001 or less) bearings. Both bearings are harder and more resistant to corrosion than conventional stainless steel or beryllium-copper alloys.
