Corrosion-Resistant Bearings

Overview

DGBB

Highly corrosion-resistant bearings are used in tough environments where water, weak/strong acids, alkali, or reactive gases are present.

Our stainless steel, hybrid, Molded-Oil™, and coated bearings stand up to moist and wet environments while our ceramic and ESZ bearings withstand weak acid and alkaline environments. For environments where strong acids and reactive gases are present, we offer ceramic bearings and Aqua-Bearings™.


Product List

Deep Groove Ball Bearing, Stainless Steel, 3Comp

Stainless steel bearings, a standard line in our SPACEA Series for special environments, are affordable options especially suited for high-humidity environments.

Features

  • Corrosion-resistant
  • Resistant to wet/humid environments
    Stainless steel bearings provide long-life even when exposed to water splashes, etc.

Applications

  • Wide applications
    Stainless steel bearings are used in all kinds of machines exposed to high humidity.
  • Transport/conveyance equipment
Deep Groove Ball Bearing, Spacea, Molded-Oil, 2Comp

Molded-Oil™ bearings feature a special material that provides a continuous supply of lubricating oil, allowing them to stand up to dust-contaminated environments at atmospheric pressure.

Features

  • Resistant to wet/humid environments
    Molded-Oil bearings provide long-life even when exposed to water splashes, etc.
  • Improved cleanliness
    No need for grease refilling minimizes oil leakage.

Applications

  • Washers in semiconductor production
  • Washers in hard disk manufacturing
DGBB

Hybrid bearings combine ceramic balls with fluororesin self-lubricating cages to achieve excellent resistance to corrosion at both atmospheric pressure and in vacuum.

Features

  • Grease-free
    Lubrication provided by solid lubricant eliminates the need for grease.
  • Highly corrosion-resistant
    Approximately 5 times more resistant to corrosion in water than stainless steel bearings.

Applications

  • Fruit washers
  • Washing equipment used in fishing/fisheries
Deep Groove Ball Bearing, Spacea, Nickel Alloy, 2Comp

Corrosion-resistant coated bearings feature a nickel coating on the outer and inner rings to enhance durability.

They stand up to high-temperature corrosive environments at atmospheric pressure.

Features

  • Highly resistant to corrosion
    A specialized coating provides excellent corrosion resistance.
  • Suitable around disinfectants
    Coated bearings can also be used in environments with hypochlorous acid and oxonia.

Applications

  • Disinfecting equipment
  • Etching equipment
Highly Corrosion-Resistant ESZ Bearings with High Hardness Stainless Steel

ESZ bearings use specialized high-hardness stainless steel to offer better corrosion resistance than martensitic stainless steel.

With 30% greater hardness and corrosion resistance equal to precipitation-hardened stainless steel, these bearings stand up to tough corrosive environments at atmospheric pressure.

Features

  • Highly corrosion-resistant
    ESZ bearings provide exceptional resistance to corrosion outclassing other stainless steel bearings.
  • Long-life
    Anti-wear properties contribute to long operating life.

Applications

  • High-performance film washing equipment
  • Beverage sterilizers
Deep Groove Ball Bearing, Spacea, All-Ceramic, 2Comp

With ceramic outer/inner rings and balls, nonmagnetic all-ceramic bearings have self-lubricating fluororesin cages to achieve excellent resistance to corrosion at both normal atmospheric pressure and in vacuum.

Features

  • Non-magnetic construction
    An all-ceramic structure gives these bearings the highest resistance to corrosion.
  • Long-life
    Anti-wear properties contribute to long operating life.

Applications

  • Chemical mechanical polishing/planarization (CMP) equipment
  • Electron beam lithography equipment
DGBB

Aqua-Bearings™ feature special fluororesin outer/inner rings and cages equipped to meet a broad range of applications in water, alkali, and strong acid environments. Aqua-bearings are suitable for corrosive environments at normal atmospheric pressure.
