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.PRODUCT LIST :1. DL2 Clean Grease-Packed BearingsDL2 clean grease-packed stainless steel bearings are suitable for clean environments from normal atmosphere up to vacuum.2. Hybrid BearingsHybrid bearings, combining ceramic balls and fluororesin self-lubricating cages, are suitable for corrosive environments from normal atmosphere up to vacuum.3. 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.4. 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.
5. YS High-Temperature Bearings with Spacer JointsYS 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.6. SJ High-Temperature Bearings with Solid LubricationSJ 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.7. Completely Non-magnetic Titanium Alloy BearingsTitanium 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.8. High Corrosion-Resistant, Non-Magnetic Stainless Steel ESA BearingsESA 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.9. 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.
