Bearings for High-Temperature Environments

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.

Bearings for High-Temperature Environments

Product List

High-Temperature KPM Grease-Packed Bearings

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 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 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.
