Drawn Cup Needle Roller Bearing :


The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall.The drawn cup needle roller bearing has the characterstics of small radial section area, large load carring capacity ,less inertia and economic manufacture. It is suitable for small section heght, or when the housing bore isnot used for raceway , this type is recommended to use .The bearing is assembled into the housing bore under a certain pressure without fu rther axial location.

 

The draw up needle roller bearing generally takes its shaft diameter as the internal raceway .However , the proper LR type inner ring can be  used in accordance with application condition.

Q:Dimensions of needle roller bearings
There isn't such a strong needle roller. But look at the picture. It's likeHave not seen in kind, in terms of size, there is a support roller meet, estimate and reference it, not necessarily accurateBrand: Germany INA NATR30 if the seal is: NATR30UUThe following diagram: small d:30 D:62 C:28 B:29Cheaper to use in Japan, IKO, model is: NART30
Q:What are the differences between cylindrical roller bearings and needle roller bearings?
Back to the 2# plane thrust roller, there are also, such as K811, K812, K893, K894. The first two are single row roller, K893 and K894 are double row roller, these are thrust bearings, INA code name, you can scroll down the directory
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:How much speed can the needle bearing of inner bore 17mm bear?
There are many kinds of needle roller bearings, which do you think?
Q:Needle roller bearings are how to process the needle, so smooth finish?
The process of needle: blank forming, deburring, heat treatment, coarse and fine grinding, end rolling surface, super finishing rolling surface polishing or sawdust.For flat head or taper head needle roller, such as blank forming, it is difficult to guarantee the length and size tolerance, and the grinding double end process can be increased. If the convex generatrix rolling surface is needed, it can be carried out directly in the process of super finishing, rolling or channeling.Needle roller bearing (needlebearing) is a roller bearing with cylindrical roller, relative to its 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 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. The needle roller bearing for stamping outer ring is needle roller bearing with thin stamping forming outer ring.
Q:Needle roller bearing model NK what does it mean?
Light series needle roller bearing without inner ring
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: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 are the needle roller bearings with an inner diameter of 14, an outer diameter of 20 and a width of 20?
Only know the inside diameter, the outside diameter and the height. There are many kinds of needle roller bearings!!
Q:Many one-way needle roller bearings have small holes in the inner and outer rings. What's the function of these small holes?
It's all oil holes, but if it's needle roller bearings, there should be very little oil holes. We also do one-way needle roller bearings, but there are no oil holes, there are oil holes are generally reflected in other series
