Cylindrical roller bearings High speed low noise
N NU NJ NUP Product Description The cylindrical
roller and raceway are linear contact bearings. Large load
capacity, mainly bearing radial loads. The friction between the
rolling element and the collar edge is small, suitable for
high-speed rotation. According to the presence or absence of ribs
on the ring, it can be divided into single row cylindrical roller
bearings such as NU, NJ, NUP, N, NF, and double row cylindrical
roller bearings such as NNU and NN. The bearing is a separable
structure with inner and outer rings. Cylindrical roller bearings
without retaining edges on the inner or outer rings can move
relative to the axial direction, so they can be used as free end
bearings. A cylindrical roller bearing with double ribs on one
side of the inner and outer rings, and a single rib on the
other side of the ring, which can withstand a certain degree
of axial load in one direction. Generally, steel plate stamped
cages or copper alloy solid cages are used. But some also use
polyamide shaped cages. Detailed PhotosProduct

TypeopenSpecifition N type: The inner ring has two integral
flanges and the outer ring is without flanges. Axial displacement
of the shaft with respect to the housing can be accommodated in
both directions within the bearing itself. The bearings are
therefore used as non-locating bearings.NU type: The outer ring of
bearings of the NU design has two integral flanges and the inner
ring is without flanges. Axial displacement of the shaft with
respect to the housing can be accommodated in both directions
within the bearing itself.NJ type: The outer ring has two integral
flanges and the inner ring one integral flange. The bearings are
therefore suitable for the axial location of a shaft in one
direction.NF type: The outer ring has one integral flange and the
inner ring two integral flanges.NUP type: The outer ring has two
integral flanges and the inner ring one integral flange and one
non-integral flange in the form of a loose flange ring. The
bearings can be used as locating bearings, i.e. they can provide
axial location for a shaft in both directions.RN type: No
outer ring and the inner ring two integral flanges.NN type: NN type
bearing without ribs on outer ring,there is a wall in the
midel of between both sides of inner ring. It can make shaft
relative bearing between the axial displacement generated in both
directions.Company ProfileShandong Wangtai Bearing Co., Ltd. was

Enterprise spirit: integrity, gratitude, equality, mutual
respect!Packaging & Shipping FAQQ: Why did you choose
us? A. We provide the best quality bearings with reasonable price,
low friction, low noise and long service life. B. With sufficient
stock and fast delivery, you can choose our freight forwarder or
your freight forwarder. C. The best service provided by
a well-trained international sales team. Q: Do you accept
small orders? Surely, once your bearings are standard size
bearings, even one, we will also accept. Q: How long is your
delivery time? Generally speaking, if the goods are in stock, it is
1-3 days. If the goods are out of stock, it will take 6-10 days,
depending on the quantity of the order. Q: Do you provide samples?
Is it free or extra? Yes, we can provide a small amount of
free samples. Do you mind paying the freight? Q: What should
I do if I don't see the type of bearings I need? We
have too many bearing series numbers. Sometimes we can't put them
all on web. Just send us the inquiry and we will be very happy to
send you the bearing details. Welcome to contact me anytime!
