Rna 6908 is high quality needle roller bearing

Needle roller bearing rna 6908, with flange, (NA0000, NKI, RNA 0000).This model is mainly used in tap grinder, fitness and sports equipment, impression materials, food processing, industrial ventilation fan motor, material handling equipment, vacuum generator, spring industry, water conservancy machinery, car lights.
Rna 6908 bearings: bearings for motorcycles' engines and gears are required to have foreign body resistance and high rigidity because they are required to be used at high temperature, high speed rotation in a foreign body environment and under the condition of large impact load.

How to assemble rna bearing?
Coat the outer diameter of the auxiliary sleeve with a thin layer of lubricating oil and sleeve it into the outer ring of the rna 6908 bearing, so that the auxiliary sleeve and the outer ring of the rna 6908 bearing form an annular hole.
For needle roller bearings without inner ring or outer ring, when installing, the rolling surface of the shaft or shell hole can be coated with a thin layer of grease, and the needle is attached to the grease of the installation part in turn.

When placing the last needle roller, there should be a gap, and the size of the gap should be 0.5mm on the circumference of the bearing.Do not hard squeeze the last needle roller into it, or one less needle roller, because the rna 6908 bearing will be stuck and cannot rotate during hard squeeze;If the clearance is too large, it is easy to cause the needle rolling and breaking when the rna 6908 bearing is running.For needle roller bearings with only the outer ring stamped, because the outer ring wall is very thin, do not use a hammer to hammer the installation, and press should be used.Because the pressure is not uniform when the hand hammer is beating.
