NR：Snap ring groove in the outer

ring, with appropriate snap ring

N1：One locating slot (notch) in one

outer ring side face

N2：Two locating slots (notches) in

one outer ring side face, 180° apart

J：Stamped steel cage, roller centred

M：Machined brass cage, riveted,

roller centred

MA：Machined brass cage, riveted,

cage)

S1：Bearing rings heat stabilized for

operating temperatures ≤ 200 °C (390 °F)

S2：Bearing rings heat stabilized for

operating temperatures ≤ 250 °C (480 °F)

CN：Normal radial internal clearance;

only used together with an additional letter

that identifies a reduced or displaced

clearance range

H Reduced clearance range corresponding to the upper half of the actual

clearance range

L Reduced clearance range corresponding to the lower half of the actual

clearance range

M Reduced clearance range corresponding to the middle half of the actual

clearance range

The above letters are also used

together with the clearance classes C2,

C3, C4 and C5, e.g. C2H

C2：Radial internal clearance smaller

than Normal
