Cylindrical Roller Bearings
Due to the line contact involving rolling elements and raceways, cylindrical
roller bearings get higher radial load capacity and they are suited to
high-speed software programs. Together with a excessive strength cage design
within pressed steel, the most cylindrical roller bearings involve machined
brass or polyamide and provide low noise, low heating generation and, for much
more difficult applications, could be provided in a variety of advanced special
materials.
N Style single strip - N style cylindrical roller bearings get
two machined flanges inside inner ring with no flanges on the outer ring, with
rollers and cage on the inner ring. Much like the NU style, the N doesn't have
thrust load carrying capability.
NU style single strip - NU style
cylindrical roller bearings get two machined flanges inside outer ring with no
flanges in the inner ring.
NJ style single strip - NJ style cylindrical
roller bearings get two machined flanges inside outer ring plus a machined
flange on one side in the inner ring. The roller and cage assembly is the outer
ring. The integral flange relating to the inner ring enables this bearing to
deal with an axial load.
NH style single strip - NH style cylindrical
roller bearings have two machined flanges in the outer ring accompanied by a
machined flange on one side in the inner ring. A special-design inner ring
enables utilization of a stabilizing ring to the non-flange side. Consequently,
these bearings can carry axial a whole lot in both directions. The roller and
cage assembly is mounted in the outer ring.
NF style single strip - NF
style cylindrical roller bearings get two machined flanges in the inner ring and
additional flange in the external ring, with roller and cage on the inner ring.
Much such as the NJ bearing, these bearings possess some thrust load
capability.
NUP style single strip - NUP style cylindrical roller
bearings are such as the NJ style and come with a special ring called a thrust
collar. Mounted on the non-flange side of your inner ring, the thrust collar
allows the bearing to maintain an axial load in both directions. The thrust
collar extends away from your bearing on one side, therefore the dimensions
along the inner ring is slightly above that of the external ring.
Double
row designs (NN, NNU) - Increase Row cylindrical roller bearings are denoted by
two N's inside part number (i. g., NN or NNU). The length of these can be from
the Super Precision component of this catalog and may be ordered with standard
perfection.
Constant Caster Roller Bearings - These are generally 2-split
bearing units on the highly reliable design and get a long service existence.
Cylindrical roller bearings with self-aligning rings that has a proper alignment
function.
S-Type - Sealed-Clean Bearings for chain conveyors demonstrate
a better efficiency under high environment and wet conditions for a longer
period by having an better sealing system. These types of bearings are packed
with a quality grease of high thermal resistance and longevity.
Four Row
Cylindrical Roller Bearings - Usually are popular roll neck bearings giving
several advantages. First, the inner ring is separable form the outer ring and
rollers so that the inner ring to keep with the roll all through grinding
processes. This ensures precise concentricity and minimal run-out providing for
excessive rolling accuracy. Second of all, this design enables greater radial
load carrying together with higher operating speeds. Four row cylindricals
should be used along with a thrust bearing that is normally a two row taper,
angular get hold of ball bearings, or perhaps a heavy groove ball bearing
according to the thrust load present.
