Needle bearing

 Needle roller bearings is a cylindrical roller bearing, roller relative to its diameter, thin and long.Needle roller as such.Despite having a smaller cross section, still has a higher load bearing capacity, therefore, especially suitable for the radial space-constrained occasions.  

 
No.2: Needle Bearing Specification

Needle bearing feature:

Needle roller bearing with thin and long roller (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the length of the roller), so the radial structure is compact, its diameter size and load capacity and other types of bearings are the same, the outer diameter of the smallest, especially suitable for the radial dimension restricted bearing fruit.According to different use occasions, can choose the inner ring bearings or needle roller and cage assemblies, with the bearing surface and match the shaft neck housing bore surface directly as a bearing inner, outer rolling surface, to ensure that the load capacity and operating performance and bearing the same with rings, a shaft or housing holes groove surface hardness, the machining precision and the surface quality of bearing ring raceway and similar.These bearings can only bear radial load.  

Mentioned below are our bearing type range:

Spherical roller bearing,taper roller bearing

Cylindrical roller bearing,thrust roller bearing

Deep groove ball bearing,angular contact ball bearing

Thrust ball bearing,Slewing bearing,needle bearing

Split bearing,pillow block bearing,Rod end bearing,non-standard bearing

 Other sizes:

Needle bearings are roller bearings with rollers that have high length-to diameter ratios. 

Needle bearings are used in farm and construction equipment, automotive transmissions, small gasoline engines, gear pumps, small appliance and tool motors, alternators, and aircraft controls.

Needle bearings are usually lubricated with grease, but oil or oil-mist  lubrication  is  preferred for heavy-duty or  high-speed applications. 

Many light-duty needle bearings never require relubrication, but high loads or speeds demand it.

Compared with other roller bearings, needle bearings have much smaller rollers for a given bore size. 

Needle bearings have the highest load capacity for a given radial space of all rolling-element 

bearings, but their use is limited to bore diameters less than *0 in.
 

Advantages:

1) Linear bearing is a low-cost production linear motion system for endless stroke used together with linear shaft. 

2) The load is small.

3) High friction resistance can get high precision rotating in the smooth movement.
 

Applications: 

Linear bearing widely used in electronic equipment, tension tester and digital 3d coordinate measurement equipment and other precision equipment, 

and multi-axis machine, punch, tool grinding machine, automatic cutting machine, 
printer, card sorting machine, 

ShiPinBao installed the sliding parts such as industrial machinery.

NO.3: Advantage of the bearing manufacturer

• Sustain radial,acial,or compasite load.
• Provide both high-running accuracy &high-speed operation
• Can replace high speed angular contact ball bearings
