ProductDescription : In applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings take up no more space than a conventional thrust washer.

Needle bearings are normally lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications.

Bearing Steel made with heat treatment, provides high and uniform hardness, good wear resistance, and high contact fatigue performance.

Notice:

Keep clean to prevent dust from entering the bearing.

Do not make strong impact on the bearing during use.

Needle Roller Thrust Bearings can accommodate axial loads in one direction only.
