Description of needling roller:
Needle roller bearing is a bearing unit composed of machined outer ring & inner ring,cage and
needle roller assembly featuring small section height,big load capacity & rigidity,compact
structure and small size,high rotating accuracy with the structure of disposed inner ring.
Needle roller bearing is characterized by multiple structures,broad adaptability and easy
installation. It is widely used in automobile,machine toll,lathe,metallurgical,textile,printing industry and etc. Various machinery equipment. With this kind of bearing,machine design
can realize the goal of small-scale & light weight.
Types of Designs:
This kind of bearing has multiple structural styles for the choice of customers,such as
narrow & broad series,with or without inner rings,cages,rib or sealings. It can be designed
according to the special structural requirements of customers as well.
Product Precision Accuracy of needling roller:
Dimensional tolerance and geometrical accuracy is based on GB/T5801.
Mutual difference of needle roller diameter is 2 um,and the precision grade is class
G2(ISO GB/T309). The diameter of inscribed circle conforms to tolerance grade F6 before the fitting of outer ring with cage and roller assembly.
Bearing radial running clearance conforms to the value defined by class 0 group of GB/T4604
Special precision grade in based on GB/T307.1
For fuller information on the special requirement of bearing running clearance, inscribed circle
and precision grade,please contact our company.
Material of needling roller:
Material for needle roller is GCr15 bearing steel,quench-hardening HRC60-65
Material for inner and outer rings is GCr15 bearing steel,quench-hardening HRC60-65
Material for cages is quality low-carbon steel or reinforced nylon.

NSK bearings,NACHI bearings,TIMKEN bearings,KOYO bearings,IKO bearings,INA bearings, NMB bearings,BONES REDS bearings…
Non-standard bearings can be?produced according to your drawing in our factory.
A: The precision of the bearings (dimension tolerance, loading rate), internal
clearance and hardness under?heat treatment, structure of cage and material.
Q:The advantage of bearings??
(1) reduce friction and wear.
To prevent metal contact and reduce friction and wear in the contact part of the bearing ring,
rolling body and maintainer.
(2) prolong fatigue life.
The rolling fatigue life of the bearing, in the rotation, the rolling contact surface lubrication good, then extended. Conversely, the oil viscosity is low, the lubricating film thickness is not good, then shortened.
(3) exhaust friction heat and cooling.
The circulation to oil method can be used to exhaust the heat generated by friction, or from external heat, cooling. Prevent the bearing from overheating and prevent the lubricating oil from ageing itself.
Q:Application area of bearings ?
It can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, and so on.
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
A:Sample needs 3-7 days, mass production time needs 3-4 weeks.
A:We accept T/T, PAYPAL or Western Union, credit card.
