Overview
High temperature bearings use specialized lubricants to stand up to high temperatures. Grease-packed bearings are pre-filled with fluorine grease for high temperatures, while YS and SJ bearings use molybdenum disulfide (MoS2) solid lubricant to withstand temperatures up to 350°C and 400°C respectively.

High-Temperature KPM Grease-Packed Bearings
High-Temperature KPM Grease-Packed Bearings
KPM-grease packed bearings come pre-filled with NSK's long-life, high-temperature KPM grease for use at atmospheric pressure.
Features
- Long life
Specialized fluorine grease combined with NSK's unique additives extend bearing life. - Suited for high temperatures
KPM grease-packed bearings withstand temperatures up to 230°C at atmospheric pressure.
Applications
- Furnace carrier/conveyance equipment
- High-temperature components in office equipment
YS High-Temperature Bearings with Spacer Joints
YS High-Temperature Bearings with Spacer Joints
YS bearings with spacer joints use an alloy-based self-lubricating material (sintered alloy) between the balls to stand up to high-temperature vacuum environments.
Features
- Suited for high-temperature vacuum
YS bearings stand up to vacuum environments with temperatures up to 350°C. - Long life
Solid lubricant spacers lubricate the bearing and extend life.
Applications
- Ion implanters
- Sputtering equipment
SJ High-Temperature Bearings with Solid Lubricant
SJ High-Temperature Bearings with Solid Lubricant
SJ bearings have a “peapod” structure, with solid lubricant spacer joints mounted between two rolling balls in a single cage pocket, making them suited for high-temperature environments at atmospheric pressure or in vacuum.
Features
- Suited for high temperatures
SJ bearings withstand temperatures up to 400°C in both atmospheric pressure and vacuum environments. - Long life
Solid lubricant provided by the spacers and a unique cage structure extend bearing life.
Applications
- Furnace carrier/conveyance equipment
- High-temperature/performance film manufacturing equipment
FAQ
- What temperatures can bearings for high-temperature environments withstand?
-
- Bearings with grease can be used at temperatures up to 230°C while SJ bearings can be used at temperatures up to 400°C.
- What kinds of high-temperature grease are available? What are their operating temperature limits?
-
- KPM long-life fluorine grease and DL2 fluorine grease for cleanrooms support high temperatures. Generally, these greases can be used up to 230°C.
