Edit

With the sealing ring to seal the sealing type stamping outer ring needle roller bearings, in general working conditions, can protect bearings from impurities from intruding and greaseleakage. Therefore, in the use temperature range of -20 DEG -120 DEG inside, the long term operation. If can timely supplement of suitable grease or short-term use, can be used for +130 degrees centigrade.

Q:Working principle of one-way needle roller bearings
One way needle roller has a spring in the lower part of the needle
Q:How much speed can the needle bearing of inner bore 17mm bear?
This depends on the lubrication, lubricating oil viscosity, pressure is different, allowing the speed is also different
Q:Needle roller bearing model NK what does it mean?
Light series needle roller bearing without inner ring
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: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 is also called cam bearing?
According to the ball bearings, there are ball bearings, cylindrical roller bearings, tapered roller bearings, needle roller bearings belong to cylindrical roller bearingsIt seems that the cam bearings have not been heard
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:Roller needle roller bearings can be used directly as a wheel?
Yes, but it is not recommended.I. cost valueThe KR58 driven roller bearings are of great value. The purpose of the design is to maximize the effect with minimal cost, and the cost of the bearing is undoubtedly high. For example: ordinary 6306 bearings, a single bearing can withstand 1500 kilograms of weight, with 10 can be, the value of KR58 is much smaller.Two 、 operation flexibility and endurancePlain ball bearings are much more flexible than roller bearings. They are easy to purchase on the market, and it is easy to solve the problem of poor working conditions with bearings with sealed coversSome of the printing equipment is had to use this kind of bearing, the car to do this, put fine timber to petty use!!
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:Dimensions of needle roller bearings
Needle roller bearings are cylindrical roller bearings, the roller is slender, the cross-section is smaller, and the bearing capacity of the load is higher, so it is suitable for radial installation size limited supporting effect. Needle roller bearings are equipped with a thin and long roller (roller length is 3~10 times the diameter, generally less than 5mm diameter), radial structure is compact.A complete bearing code is composed of the basic code number plus one or more supplementary codes. All standard bearing SKF have certain basic types, there are usually three, four or five numbers, or letters and numbers, the first number or the first letters said bearing type, followed by two digits identifies the size of ISO series.Because the model of needle roller bearings is relatively complex, only a few specific classification and model control of needle roller bearings are introduced here:1, centripetal needle roller and cage assembly (type K)2, outer ring with double lock ring needle roller bearings (NA, NKI, RNA, NK)3. Single row needle roller bearings with double retaining rings (NA, NKI, RNA, NK)4. Double row needle roller bearings with double retaining rings (NA, RNA)5, stamping outer ring needle roller bearings (HK type, BK type)The bearing has low cost and large carrying capacity, and is suitable for the supporting structure with limited size of installation.
