Product Description

Needle Roller Bearing

20mm Drawn Cup Needle Roller Bearing HK2016 HK2020

 

Needle roller bearings (needle bearing) is a cylindrical roller with a roller bearing, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section, has a higher load bearing capacity, equipped with a thin and long needle bearing roller (roller diameter D<5mm, L / D>2.5, L is the length of the roller), therefore radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial mounting dimensions restricted support structure.

According to different occasions, can be used without inner ring of the bearing or needle roller and cage assembly, when the surface of the journal bearing surface and shell holes as bearing directly match the outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing rings. Such bearings can only bear radial load.

Application:
Needle roller bearings are widely used in cars, compressors, construction, electric motors, food industry, home appliances etc. As a rolling element, it turns the world.

1.Bearing Specifications :
Needle roller bearings use long, thin cylindrical rollers to support radial loads. These needle rollers have a length that is
typically three to four times its diameter. Needle roller bearings have a thinner cross section than other roller bearings and are ideal for limited-space applications that require carrying heavy loads. Drawn cup needle roller bearings have a deeply drawn, thin-walled outer ring. Caged drawn cup units contain a one-piece cage to guide and retain the rollers. Full-complement drawn cup units include the maximum number of rollers that can be retained by the outer shell. The drawn design allows for cost-effective accommodation of heavy radial loads. Needle roller and cage assemblies do not contain inner or outer rings. Instead, the self-contained bearing components work with a shaft or housing bore used as a raceway.

Our Advantages

Advantages of needle roller bearings

Needle roller bearings are equipped with thin and long rollers. Therefore, the radial structure is compact.

When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest. It is especially suitable for the support structure with limited radial installation size.

Needle roller bearings should be combined with bearing rings and applications depending on the application occasions, machining accuracy and surface quality

  

 

Product Application

2.Application of Bearing :
1.Needle roller bearing: used in automobile engine, transmission, crawler wheel of excavator, compressor, crane, etc.2.Combined needle roller bearing is widely used in machine tools, metallurgical machinery, textile machinery, printing machinery and other mechanical equipment, and can make the mechanical system design very compact and smart.
