Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spit of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.The outer rings of this needle bearings and bearings case are interference fitted without axial fixed settings. The effcient capacity can be maintained even if in the condition of high speed and huge loading capacity.

 

MBY Bearing Technology Co., LTD has all kinds of needl roller bearings, including K,K...ZW,HK,BK,HK...RS,HK...2RS,BK...RS,NKS,RNA49,RNA48,RNA69,NKI, NKIS,NA49,NA69,HFL,CY3X, F, NAG,CF-1-2B,CF-2-SB etc.



Product Applications:


Needle roller bearings are mainly used in car engines, transmissions, compressors, cranes, etc.

Q:Working principle of one-way needle roller bearings
The main structure of the unidirectional bearing EG unidirectional roller bearing EG-- | stamping outer ring needle roller clutch (one-way bearing) can be used as a converter, a non-return device, overrunning clutch. HF (needle roller clutch): composed of stamping outer ring and plastic cage. The cage can be provided with plastic spring or stainless steel leaf, guide roller, roller, roller and needle on outer ring as locking device. HFL (clutch and bearing assembly): support bearings are mounted on both sides of the needle clutch and bear radial loads. The needle bearings and plastic cage assemblies are used as supporting bearings
Q:What is the bearing capacity of needle bearing and copper sleeve?
The copper sleeve and the shaft are surface contact, and the bearing capacity is large;The needle roller of needle roller bearing is several line contact, and it has less bearing capacity than copper sleeve;The sliding friction, friction force is large, suitable for low speed and heavy load, preferably with good lubrication, in static pressure under the condition of high speed, such as grinding machine is of high speed and heavy load static and vibration resistance than good bearing;The latter is rolling friction, and the transmission efficiency is higher, suitable for medium speed.
Q:Needle roller bearing model NK what does it mean?
Light series needle roller bearing without inner ring
Q:What is the needle roller bearing model with outer diameter 21 and inner diameter 16?
Needle bearing roller bearings are cylindrical roller, relative to its diameter, the roller is thin and long, hence the name. Although the needle roller bearings with a smaller section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, its diameter and load capacity and other types of bearings at the same time, minimum diameter, especially for the supporting structure of radial installation size limited.
Q:What are the differences between cylindrical roller bearings and needle roller bearings?
What are the differences between cylindrical roller bearings and needle roller bearings? In particular, if the roller and needle diameter is about the same, cylindrical roller bearings and inner ring needle roller bearings seem to be difficult to identify it
Q:What are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?
Is the needle roller and cage assembly? Or with stamping outer ring needle roller bearings?
Q:What are the differences between needle roller bearings and cylindrical roller bearings?
Mainly the difference between rolling bodiesThe needle length and diameter ratio (aspect ratio) is greater than 3, less than 5 mm in diameterThe cylindrical length and diameter ratio (aspect ratio) is less than 3, greater than 5 mm in diameter
Q:Cylindrical roller bearings and needle roller bearings is the same thing?
Cylindrical roller bearings, rolling bodies are cylindrical roller bearings. Cylindrical roller and raceway are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the ring block is small and suitable for high speed rotation. According to the ring has no edge, can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. Needle roller bearings are cylindrical roller bearings, relative to their diameter, the roller is thin and long. This roller is called needle roller. Although it has a small section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, the minimum diameter of the diameter and load capacity and other types of bearings, bearing the same, especially for the structure in radial installation size limited. According to the use of different occasions, can choose the inner ring of the bearing or needle roller and cage assembly, the shaft neck surface and the surface of shell holes matched with a bearing directly as the bearing inner and 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 the machining precision and the surface quality of bearing ring raceway and similar. This kind of bearing can only bear radial load.
Q:The difference between NK type and NKI type in needle roller bearings
NK and NKI are light series needle roller bearings. The difference is that one with inner ring and one without inner ring. The following problems are shown. Relevant technical data of the model are compared. Are they in line with your requirements?:INA needle roller bearing NK40/20-TVLight seriesFw 40, mmD 50, mmC 20, mmRmin 0,3 mmM 78 g qualityCr 26000 N basic rated dynamic load radialC0r 47000 N basic rated static load radialCur 6700 N fatigue limit load, radialNG 10900 1/min limit speedNB 6400 1/min reference speedINA needle roller bearing NKI35/20-TVLight seriesD 35, mmD 50, mmB 20, mmF 40, mmRmin 0,3 mmS, 0,5, mm axial displacement distanceM 122 g qualityCr 33500 N basic rated dynamic load radialC0r 56000 N basic rated static load radialCur 9800 N fatigue limit load, radialNG 11500 1/min limit speedNB 6200 1/min reference speed
Q:Many one-way needle roller bearings have small holes in the inner and outer rings. What's the function of these small holes?
The basic structure and NU type cylindrical roller bearing inner ring bearing the same, but because of the needle, the volume can be reduced, and can bear large radial load to the bearing without inner ring shaft mounting surface with suitable precision and hardness as the raceway surface
