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.
DL2 clean grease-packed stainless steel bearings are suitable for clean environments from normal atmosphere up to vacuum.
Hybrid bearings, combining ceramic balls and fluororesin self-lubricating cages, are suitable for corrosive environments from normal atmosphere up to vacuum.
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 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 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.
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.
