Non-Magnetic Bearings

Overview

Non-Magnetic Bearings

Nonmagnetic bearings offer higher rigidity and greater resistance to corrosion than conventional stainless steel or beryllium-copper alloys.

Product List

All-Ceramic Bearings (Oxide-Based Ceramic Bearings)

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

  • Fully nonmagnetic
  • Excellent resistance to corrosion and wear

Applications

  • Semiconductor inspection equipment
  • Laser inspection equipment

FAQs

?

answersYes, stainless steels can be magnetic. For example, ferrite stainless steel (SUS440C) will interact with nearby magnets.
In contrast, austenite stainless steel (SUS304) has nonmagnetic properties; however it may become slightly magnetic if processing such as cutting or grinding deforms its crystal structure.
To ensure that steel is nonmagnetic, it must be demagnetized. If this is not possible, we recommend using all-ceramic bearings as they will always maintain their nonmagnetic properties.

?

answersPlease use a loose fitting for the shaft and housing.

?

answersInstead of grease, ceramic bearings are lubricated by the solid lubricant within the cage.
