Cylindrical roller bearings are manufactured in a number of designs as indicated below.The predominant
type being the single row roller. The roller and cage assembly are guided axially by the integral
flanges (ribs) on one of the bearing rings. This design facilitates ease of mounting and dismounting,
particularly where both races are an interference fit on their seatings. Roller bearings with flanges (ribs)
on one race only do not provide any end location. Various roller bearings with ribs on both races provide
axial location, and are capable of carrying light or intermittent axial loading. These patterns are of
the NJ, NUP and NJ+HJ types. If used for axial location and light axial loads, the contact between the
flanges (ribs) and the roller ends is that of a sliding bearing, not rolling bearing; therefore
lubrication is of paramount importance.
Alignment is much more critical than that of a ball bearing; as a general guide, this is limited to
approximately .003 radians. Double and multi-row bearings are also manufactured
- see NN and NNU series.
Dimensions in accordance with ISO 15-2011
Of these bearings, the NJ, NUP and NJH types can also
carry light or intermittent thrust loads between the guide rib
and the end of the rollers. Several arrangements of locating
ribs are available, as illustrated. The choice between these
types is usually decided by consideration of assembly procedure
or machine clearances. The bearings utilizing machined
bronze cages are suitable for high speed operation. The NN
30 and NN 30 K series are available in high precision tolerances
and, due to their extreme rigidity, are particularly suited
for use in machine tool spindles.
Typical suffixs used for cylindrical roller bearings:
E - Increased loading capacity
NA - Non-interchangeable components
M - Brass cage guided on the rollers
EM - Increased loading capacity and brass cage guided on the rollers
EMA - Increased loading capacity and brass cage guided on the outer ring
