Product Details
High Precision Needle Roller Bearings NA5904 for Equipments and
Machines
Needle roller and cage assemblies are self-contained,
ready-to-mount bearings. In applications where the shaft and
housing bore can serve as raceways, the assemblies can be used to
create bearing arrangements that require minimal radial space.
Application:
The needle roller bearing can be used in Transmission, gearbox,
engine, valve parts, steering and braking system, axle support,
outboard engine, power tools, photocopying fax machine, paper
feeding equipment, etc.
Features and benefits:
Lowest cross section among rolling bearings
In applications where less space is available, needle roller and
cage assemblies offer a very compact solution.
High load carrying capacity
Owing to their large number of rollers, needle roller and cage
assemblies have a high load carrying capacity.
High stiffness
Because of their large number of small-diameter rollers, needle
roller and cage assemblies have high stiffness.
Company Profile
In 2010s, WI-TECH embarks on the production and supply of ceramic
bearings, plastic bearings and hybrid ceramic bearings, and since
then we have been a leading manufacturer and supplier of ceramic
bearing in China that supports the growth of global industry. At
our production plant, which is integrated with advanced technology,
we operate the production line for the ceramic bearings and
automate everything from processing to quality control.
In addition, the tolerances for bearing finishes are more stringent
than the standards of China industrial standards, and our bearings
can be fully responsive to demanding conditions such as high-speed
rotation. Taking advantage of a specialized manufacturer, Witech
ceramic bearings can withstand the severe environment such as heat
resistance, corrosion, wearing and magnetic in recent years. In
addition, we are highly acclaimed for the production of various
types such as stainless steel series and hybrid series.
In contrast with plain bearings, ceramic bearings are easy to
install and withstand more severe conditions. We are confident that
we will be able to contribute to the industry in a variety of
fields. We will continue to create new value for the changing
future and to be able to satisfy the user’s needs 100%.
