Cleanroom Bearings
Overview
Cleanroom bearings aim for zero particle emissions.
By applying NSK's unique technologies, our range of offerings excel across environments at atmospheric pressure, in vacuum, and with high temperatures.
Products
LG2 and LGU grease-packed stainless steel bearings are suitable for cleanroom environments at atmospheric pressure with normal temperatures.
Features
- Low grease scatter and particle emissions
- Long life
Applications
- Cleanrooms
- Film manufacturing equipment
DL2 grease-packed stainless steel bearings are suitable for cleanroom environments at atmospheric pressure or in vacuum.
Features
- Low grease scatter and particle emissions
- Superior heat resistance
Specialized DL2 grease supports higher operating temperatures.
Applications
- Semiconductor manufacturing equipment
- Film manufacturing equipment
DFO bearings feature special lubrication coatings applied to the rings, balls, and cage to deliver superior cleanliness and long-life.
The E-DFO specification uses a low-vapor-pressure hydrocarbon lubricant coating, while V-DFO uses a fluorine oil lubricant coating.
These new-concept bearings are suited for cleanroom environments at atmospheric pressure and in vacuum.
Features
- Low particle emissions
Specialized cleanroom grease keeps generated particles low. - Low outgassing
Applications
- Semiconductor manufacturing equipment
- Organic electro-luminescence (OEL) manufacturing equipment
