cylindrical roller bearings
a、Lower speed than the ball bearing with the same dimension
c、Low noise and small vibration
d、Mainly withstand radial load
e、Can withstand a litter axial load if outer ring and inner ring have ribs
Cylindrical roller bearings are available in many designs, series and sizes. The
majority are single row bearings with a cage. High-capacity bearings, single and
double row full complement bearings (without a cage) complete the standard
assortment listed in this catalogue.
1.Single row cylindrical roller bearings can accommodate heavy radial loads and
high speeds. They are manufactured in several different designs, the main
difference being in the configuration of the flanges. The most popular are the NU,
N, NJ and NUP designs.
2.Double row cylindrical roller bearings mainly in the NNU design and the NN
design(fig 2). The bearings are separable, i.e. the ring with integral flanges
together with the roller and cage assemblies can be mounted separately from the
other bearing ring or all bearing components can be mounted separately. This
facilitates the mounting, inspection and maintenance of these bearings.
3.Four-row and six-row cylindrical roller bearings are used almost exclusively for
the roll necks of rolling mill stands, calenders and roller presses. Their friction
is low compared with other roller bearings. As they are normally mounted with an
interference fit on the roll neck, they are particularly suitable for rolling mill
applications where the rolling speed is high.
