KPM-grease packed bearings come pre-filled with NSK's long-life, high-temperature KPM grease for use at atmospheric pressure.

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.

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.

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.
