Product DescriptionNNU4956K

Bearings are an important component of contemporary machinery and equipment. Bearings Tapered Roller Bearings NNU4956K main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and guarantee its rotation accuracy. In terms of its role, it should be supportive, that is, the literal interpretation of is used to support the axis, but this is only part of its role, and its support is to be able to bear the radial load. It can also be understood that it is used to fix the shaft. Bearing Bearings Tapered Roller Bearings NNU4956K quick and easy excellent automatic selection is included. is the fixed shaft that allows it to rotate only and control its axial and radial movement. Motors do not work at all if they do not have bearings. Because the shaft may move in any direction, the motor requires the shaft to only rotate when it is working. Theoretically speaking, it is impossible to achieve the role of transmission, not only that, the bearing Bearings Tapered Roller Bearings NNU4956K will also affect the transmission, in order to reduce this effect in the high-speed shaft bearings must achieve good lubrication, and some bearings have lubrication, called pre-lubricated bearings, and Most bearings must have lubricating oil, responsible for high-speed operation, because friction will not only increase energy consumption, but more terrible is that it is easy to damage the bearings. The argument for turning sliding friction into rolling friction is one-sided because there is something called a sliding bearing Bearings Tapered Roller Bearings NNU4956K.

HERO BEARING CO., LIMITED Bearings Tapered Roller Bearings NNU4956K rollers and raceways are line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the collar rim is small, suitable for high-speed rotation. According to whether the collar has ribs, Multi-Row Roller Bearings NTN can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, etc., and double row cylindrical roller bearings such as NNU and NN. The bearing Bearings Tapered Roller Bearings NNU4956K is a detachable inner and outer ring structure.
Bearings Tapered Roller Bearings NNU4956K Inner ring or outer ring without cylindrical roller bearings, the inner ring and outer ring can be relative to the axial movement, it can be used as a free end bearing. A cylindrical roller bearing Multi-Row Roller Bearings NTN with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Bearings Tapered Roller Bearings NNU4956K General use of steel stamping cage, or copper alloy car body cage. However, there is also a part that uses a polyamide forming cage.
HERO BEARING CO., LIMITED The cylindrical roller is in line contact with the raceway and has a large radial load capacity. It is suitable for both heavy and impact loads as well as high speed rotation. Cylindrical roller bearings raceways and rolling elements are geometrically shaped. After the Bearings Tapered Roller Bearings NNU4956K improved design, Multi-Row Roller Bearings NTN the new structure design with high load-bearing capacity, ribs and roller end face not only improves the axial bearing capacity of the bearing, but also Bearings Tapered Roller Bearings NNU4956K improves the lubrication conditions of the contact area between the roller end face and the rib and improves the Bearing performance.
Bearings Tapered Roller Bearings NNU4956K are separate bearings that are easy to install and remove. Cylindrical roller bearings can withstand large radial loads and are suitable for use in high speed applications.
This type of bearing Multi-Row Roller Bearings NTN allows the angular error (inclination) of the inner ring axis and the outer ring axis to be very small, only 2' to 4'. Therefore, the machining accuracy of the shaft and the bearing housing is relatively high. Otherwise, uneven load or stress concentration tends to occur at the contact portion of the raceway. However, correction of the roller or raceway contact busbars Multi-Row Roller Bearings NTN can reduce stress concentration.
Vibration aspects
In normal use, Bearings Tapered Roller Bearings NNU4956K vibration is very sensitive to damage to the bearing. Peeling, indentation, rust, cracks, wear, etc. are all reflected in the bearing vibration measurement. Therefore, the magnitude of the vibration can be measured by using a special bearing vibration measurer (frequency analyzer, etc.), and the abnormal condition can be inferred from the frequency distribution. The measured value differs depending on the conditions of use of the bearing or the mounting position of the sensor. Therefore, Bearings Tapered Roller Bearings NNU4956K is necessary to analyze and compare the measured values of each machine beforehand to determine the judgment criteria.
Temperature aspects
The use of high temperatures often indicates that Multi-Row Roller Bearings NTN have been in an abnormal condition. High temperatures are also detrimental to bearing lubricants. Sometimes bearing Multi-Row Roller Bearings NTN overheating can be attributed to bearing lubricants. If the bearing is continuously rotated at a temperature over 125°C, the bearing life will be reduced. Causes of high-temperature bearings include: insufficient lubrication or excessive lubrication, bearing raceways containing impurities, excessive speed limit, long-term overloaded bearings and so on.
