Bearings for Vacuum Environments

 Overview

 Product List

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.

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.

DL2 Clean Grease-Packed Bearings

DL2 clean grease-packed stainless steel bearings are suitable for clean environments from normal atmosphere up to vacuum.

All-Ceramic Bearings (Oxide-Based Ceramics)

Hybrid Bearings

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

Clean Lubricant V-DFO Bearings

V-DFO bearings feature a new innovation: a fluorine oil coating is applied to inner/outer rings, balls and cage to deliver cleanliness and long life. These bearings are suitable for use in clean environments from normal atmosphere up to vacuum.

YS bearings with MoS2 self-lubricating cages

YS bearings for clean environments have newly developed self-lubricating cages, delivering high cleanliness and long life.
These bearings are suitable for clean environments from normal atmosphere up to vacuum.

YS high-temperature bearings with spacer joints

SJ high-temperature bearings with solid lubrication

SJ high-temperature bearings with solid lubrication have a “peapod” structure, with solid lubricant spacer joints mounted between two balls in cage pockets. These bearings are suitable in vacuum, high-temperature environments.

Completely non-magnetic titanium alloy Bearings

Titanium alloy bearings have special titanium alloy inner/outer rings and ceramic balls, making them completely non-magnetic (relative permeability 1.001 or less). These bearings are suitable for non-magnetic requirement from normal atmosphere up to vacuum.

YS high-temperature bearings with spacer joints made of an alloy-based self-lubricating material (sintered alloy) between balls. They are suitable for high-temperature and vacuum environments.

 Related Industries

Bearings for vacuum environments are basic products of the NSK SPACEA Series for special environments, which also includes bearings suitable for operating environments such as corrosive, clean, and high-temperature environments, and non-magnetic requirement.
