NUP series Cylindrical Roller Bearing NUP 312 Bearing chrome steel
Cylindrical Roller Bearing Features:
1. Roller and groove for line contact or repair referral contact,
radial load capacity, is designed to withstand heavy load and
impact load.
2. Small friction coefficient, suitable for high speed, limit
rotational speed close to deep groove ball bearing.
3. N-type and NU type can axial movement and can adapt caused by
thermal expansion or installation error and shell the shaft of
relative location changes, can make free use of the bearing.
4. The hole of shaft or block the demand is higher, bearing
processing after installation relative skewed to outer ring axis
and kept under strict control, lest cause contact stress
concentration.
5. Inner circle or their cups are separable, convenient in
installation and removal.
NH NU NJ NUP NF N SL type Cylindrical Roller Bearing application:
Large and medium-sized motor, locomotives, spindle, internal
combustion engines and generators, gas turbines, reducer, rolling
mill, vibrating screen and lifting transportation machinery, etc.

N typebearing housing washer no guard, both sides of the inner ring
has guard. Can allow shaft relative bearing between the axial two
direction of displacement. NU type of bearing's outer two guard,
inner ring no guard. Can also allow shaft relative bearing between
the axial two direction of displacement. Therefore, this kind of
structure is suitable for use as a floating end bearing.
NJ typebearing housing washer two guard, the inner ring of the
unilateral have guard. May have a certain amount of unilateral
axial load.
NF typeof unilateral have outer rim, the inner ring of the two
guard. Also can bear a certain amount of unilateral axial load.
Therefore, this kind of structure is suitable for single direction
as the axial location bearing with.
NUP typebearing outer is two guard, inner ring side band (fixed)
single guard, and the other side is separable flat ring. May have a
certain amount of two-way axial load.
