Ess Tee
Auto Inds. (Regd.) are
the Suppliers &
manufacturers of needle
roller bearings, roller
bearings, needle
bearings which are used
for shaft size 12mm to
25mm, used in
automobile, textile &
general machinery & for
custom product
requirements.
Needle Roller bearing
are used in applications
where compact size is
required and radial
space is limited.
Needle roller bearing
only carry pure radial
load and can not limit
the axial displacement
of shaft relative to the
housing. They have a
smaller cross-section,
higher load-carrying
capacity and greater
rigidity, which in turn
gives size and weight
reductions in machinery
& automobile engines.
We are a leading
manufacturer and
supplier of needle
roller bearings. These
bearings are
manufactured using
superior quality raw
material that ensures
durability and
performance of the
product. They are light
weight and have a
compact construction.
They are available in
varied sizes and can be
availed as per the
specific requirement of
the buyer.
Advantages:
Smaller cross-section
leading to greater
rigidity, higher
load-carrying capacity &
lower inertia of the
needle roller bearings
help size and weight
reductions in machinery
Though they are less
wide, their load
carrying capacity is
high and is most
suitable for
applications where the
load is high & the
radial space is less
Applications:
Transmissions, transfer
cases, engines & valve
trains
Steering and braking
systems
Axle support
Outboard engines
Types of Needle Roller
Bearings
Drawn cup needle roller
bearings:
These needle roller
bearings have a deep
thin walled outer ring
with open or closed
ends. These bearings
have a very low
sectional height and
have high load carrying
capacity. They are used
when a very compact
arrangement is required
and the housing bore
cannot be used as a
raceway. These drawn cup
needle roller bearings
are directly used on the
shaft.
Drawn cup needle
roller bearings with
closed ends:
These drawn cup are
manufactured of hardened
steel sheet, needle
roller and cage assembly
form a non-separable
unit. There drawn cup
needles have a large
lubricant space.
Generally, they have
only a single row of
rollers but some may
have two-needle roller
and cage assemblies
adjacent to each other
with the lubricating
hole in the outer ring.
With and without
inner rings:
These are rubbing of
polyurethane or nitride
rubber. Superior quality
of lithium base grease
is used in them. They
are a substitute for
seals. The raceways of
the shaft must have the
hardness and the surface
should have a normal
finish in order to
maximize the load
carrying capacity.
