Overview

Bearings for Vacuum Environments

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.

Product List

DL2 Clean Grease-Packed Bearings
DL2 Clean Grease-Packed Bearings

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

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.

Clean Lubricant DFO Bearings (E-DFO, V-DFO)
Clean Lubricant DFO Bearings (E-DFO, V-DFO)

DFO bearings feature a new innovation : V-DFO uses fluorine oil lubricant coating and E-DFO uses low vapor pressure hydrocarbon lubricant coating.
These bearings are suitable for use in clean environments from normal atmosphere up to vacuum.

YS High-Temperature Bearings with Spacer Joints
YS High-Temperature Bearings with Spacer Joints

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.

SJ High-Temperature Bearings with Solid Lubrication
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.

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.
