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.

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%.
