Bearings for Corrosive 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.
Stainless Steel Bearings

Stainless Steel Bearings

Stainless steel bearings, the standard products of the NSK SPACEA Series for special environments, are suitable for high-humidity environments.
Molded-Oil™ Bearings

Molded-Oil™ Bearings

Molded-oil bearings, made of stainless steel, are lubricated with NSK's original oil-impregnated material, Molded-oil™, and are suitable for corrosive and dust-contaminated environments in normal atmosphere.
Hybrid Bearings

Hybrid Bearings

Hybrid bearings, combining ceramic balls and fluororesin self-lubricating cages, are suitable for corrosive environments from normal atmosphere up to vacuum.
Corrosion-Resistant Coated Bearings

Corrosion-Resistant Coated Bearings

Corrosion-resistant coated bearings (Nickel coating) are coated with a nickel coating on the outer and inner rings to enhance corrosion resistance and durability, and are suitable for corrosive environments such as normal atmosphere or high temperature.
High corrosion-Resistant, high hardness stainless steel ESZ Bearings

High corrosion-Resistant, high hardness stainless steel ESZ Bearings

ESZ Bearings have corrosion-resistant, and are superior to martensitic stainless steel.
The bearings are having corrosion resistance equal to precipitation hardening type stainless steel and the hardness is improved more than 30%.
The bearings are suitable for corrosive environment operating under atmospheric conditions.
High Corrosion-Resistant, Non-Magnetic Stainless Steel ESA Bearings

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

ESA bearings, combining austenite stainless steel and hardened surface layers, possess high hardness, corrosion resistance and non-magnetic properties, and are suitable for corrosive environments and non-magnetic requirement in normal atmosphere and vacuum.
All-Ceramic Bearings (Oxide-based ceramics)

All-Ceramic Bearings (Oxide-based ceramics)

With ceramic outer/inner rings and balls, all-ceramic bearings have self-lubricating fluororesin cages and are suitable for corrosive environments and non-magnetic requirement from normal atmosphere up to vacuum.
Aqua-Bearings™ High Corrosion-Resistant Resin Bearings

Aqua-Bearings™ High Corrosion-Resistant Resin Bearings

Aqua-bearing features a special fluororesin for outer/inner rings and cages equipped to meet a broad range of applications in water, alkali and strong acid environments. Aqua-bearing is suitable for corrosive environments exclusively in normal atmosphere.
