The different types of cylindrical roller bearings are designated based on their structural features and intended applications: N..EM: Cylindrical roller bearing with a standard inner ring without any ribs, suitable for radial loads. NU..EM: Bearing with aremovable inner ring and two integral flanges on the outer ring, designed for high radial loads and accommodates axialdisplacement. NJ..EM: Features a removable inner ring and one integral flange on the outer ring, primarily used for applicationswhere axial displacement is required.

According to whether the ring has a rib or not, NSK cylindrical roller bearings are divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN double-row bearings. The bearing is a structure with separable inner ring and outer ring. Cylindrical roller bearings with inner or outer rings without rims, the inner and outer rings can be axially moved relative to each other, so they can be used as free-end bearings.

Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations that can withstand heavy loads and vibration loads without difficulty. Such bearings can withstand large axial loads in a single direction, but they cannot withstand radial loads, and they have no automatic aligning capability.

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high.

Tapered roller bearings are suitable for bearing radial loads, unidirectional axial loads and radial and axial combined loads. The axial load capacity of tapered roller bearings depends on the contact Angle α, that is, the Angle of the outer ring raceway, the greater the contact Angle α, the greater the axial load capacity. Generally tapered roller bearings do not allow Angle errors, but the surface of the roller and raceway can be specially designed to allow 2'~4' Angle errors.

The design of the roller and raceway contact line of all thrust cylindrical roller bearings is optimized to avoid the generation of edge effects.

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling surface can form a pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing because the rolling bus and the raceway bus of the washer converge at a certain point on the axis line of the bearing.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)294169039416801705446813802000–5.9129412903941260130422938542700—2.61294139039413651404534410002500—3.342

1.Needle roller bearings for stamping outer rings. There are two kinds of bearings: perforated type and sealed type. The needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the processing accuracy and heat treatment hardness of the shaft should be the same as that of the bearing inner ring.2. Solid ring needle roller bearings solid ring needle roller bearings, commonly used solid ring needle roller bearings are NA type and RNA type.3. Roller needle bearing4. Needle roller and cage assembly.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

A flange bearing is a bearing widely used in industrial machinery, which has a flange (usually circular) to be fixed in the mechanical equipment. The flange bearing consists of an inner ring, an outer ring, a rolling element (such as a steel ball, roller, roller, etc.), a cage and a seal.First of all, the inner ring and the outer ring are the main bearing parts of the flange bearing, they are usually made of high-quality steel, after a good heat treatment process to ensure their hardness and wear resistance.

Product Description:The 5754 Aluminum Pipe is a high-strength, non-heat treatable alloy belonging to the Al-Mg system, known for its excellent corrosion resistance, especially in marine environments and industrial settings.

Strong bearing capacity: Due to the large number of needle roller, needle roller bearings have a high bearing capacity, suitable for bearing large radial and axial loads. (2) Small starting torque: the friction inside the needle roller bearing is small, and the starting torque is small, making the starting speed of the bearing faster. (3) Simple structure: The structure of needle roller bearings is relatively simple, easy to install and maintain, and low cost.

 If the bearing seat is equipped with neutron control, pay attention to absolutely prohibit the joint phenomenon of the signal line between the die casting machine and the bearing seat, the reason is clear, in daily production, it is difficult to avoid water on the signal line, or the place where the joint is wrapped is easy to break, resulting in short contact with the machine tool, if the signal is wrong, the light alarm automatic shutdown delay time, the heavy signal disorder, Break the bearing seat. Cause unnecessary loss.

According to the different requirements of bearings and bearing seats, the classification of bearing seats is not exactly the same, and it is necessary to carefully check the selection according to the design when using.1 Classification according to the shape of the bearing seat:1.1 Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. 1.1.1.1 The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series.

NTN tapered roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads, with high stiffness and rotation accuracy, and have large bearing capacity and low limit speed compared with angular contact ball bearings. Its carrying capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the carrying capacity.
