Cylindrical Roller Bearings:
Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a structure in which the inner ring and the outer ring can be separated.
Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings 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. Generally, a steel stamping cage is used, or a copper alloy turning solid cage is used. However, there are also part of the use of polyamide forming cage.
Cylindrical roller bearings are separable bearings, which are very convenient to install and disassemble. Cylindrical roller bearings can withstand large radial loads and are suitable for use in high-speed operation.
Cylindrical roller bearings are separable bearings, which are very convenient to install and disassemble. Cylindrical roller bearings can withstand larger diameters
To the load and suitable for use in high-speed operation.
This type of bearing allows the angular error (inclination) between the axis of the inner ring and the axis of the outer ring to be very small, only 2' to 4'. Therefore, the machining accuracy of the shaft and the bearing seat is relatively high. Otherwise, uneven load or stress concentration will easily occur at the contact part of the raceway. However, the occurrence of stress concentrations can be reduced by modifying the contact busbars of the rollers or raceways.
Cylindrical roller bearings can be divided into different structures such as single-row, double-row and multi-row cylindrical roller bearings according to the number of rows of rolling elements installed. Different structural bearings are also reflected in the design of the position of the rib. Among the commonly used cylindrical roller bearings are the following
Several forms:
Single-row cylindrical roller bearings: Single-row cylindrical roller bearings are separable bearings, which are easy to install and disassemble. Both rings can be tightly fitted, and the contact line between the rollers and the raceway is corrected to reduce stress concentration.
Double-row cylindrical roller bearings: Double-row cylindrical roller bearings are floating bearings, and their separability makes installation and disassembly very convenient. Both ferrules can have a tight fit. Double row cylindrical roller bearings are hardly allowed to have a tilt angle.
Single row cylindrical roller bearings
N, NU type
The outer ring of the N-type bearing has no ribs, and there are ribs on both sides of the inner ring. Displacement in both axial directions between the shaft and the bearing housing can be allowed. The NU type bearing has ribs on both sides of the outer ring and no ribs on the inner ring. It is also possible to allow displacement of the shaft relative to the bearing housing in both axial directions. Therefore, this type of structure is suitable for use as a loose end bearing.
NJ, NF type
NJ type bearings have ribs on both sides of the outer ring, and ribs on one side of the inner ring. Can withstand a certain amount of unidirectional axial load.
NF type has ribs on one side of the outer ring and ribs on both sides of the inner ring. It can also bear a certain amount of unidirectional axial load. Therefore, this type of structure is suitable for use as a unidirectional axial locating bearing.
NUP, NFP type
NUP type bearings have ribs on both sides of the outer ring, a (fixed) single rib on one side of the inner ring, and a separable flat rib on the other side. Can withstand a certain amount of bidirectional axial load.
The bearing outer ring of the NFP type has a (fixed) single rib on one side, and a separable flat rib on the other side, with ribs on both sides of the inner ring. It can also withstand a certain amount of bidirectional axial load. This type of structural bearing can limit the displacement of the shaft relative to the bearing seat in both axial directions. Therefore, it is suitable for use as a fixed end bearing.
NH (NJ+HJ) type
The NH type bearing is the combination of the NJ type bearing and the HJ type inclined retaining ring. Because the inner ring of the NUP type bearing is short, and the flat retaining ring is not fixed, it is inconvenient to use, while the NH type bearing can use the width of the entire inner ring of the NJ type bearing to maintain a tighter fit with the shaft. Moreover, the NH type bearing is more convenient to install and disassemble.
