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.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

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

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.

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.

1.Thrust cylindrical roller bearings are often combined into high-stiffness bearing configurations, which can withstand heavy loads and vibration loads without difficulty.2. this kind of bearing can bear a large axial load in a single direction, but can not bear radial load, they do not have automatic aligning ability.3. the thrust cylindrical roller bearing can be divided into thrust cylindrical roller and cage assembly, shaft ring and seat ring.4.

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.

High load carrying capacity    The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers  High stiffness    The increased number of rollers increases radial stiffness.    High speed capabilityThe cage designs are suitable for high speeds, rapid accelerations and peak loads.  Long service life  The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:     

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.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

Linear bearings with flanges Performance: Linear bearings are a linear motion system produced at a low cost for use with unlimited travel and cylindrical shafts. Because the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with minimal friction resistance, thus achieving smooth motion with high precision.

Flange slide bearing has the features of Low friction coefficients and long usage spans, High temperature, self-lubricated, anti-corrosion. Using feature: Linear bearings are used widely in electronic equipment, pull tester and digital three-dimensional coordinate measuring device.  Such as precision equipment, as well as multi-axis machine tools, press tool, grinder automatic gas cutting machine, printer, card sorting machine, food packaging machine and other industrial machinery sliding components...

Features :Thrust ball bearings consist of two precision washers (rings) and a ball complement spaced by retainer. They can besupplied with or without radius ball grooves in the rings.

Iko tapered roller bearings have high load bearing capacity and wear resistance. Because of the conical roller design, the bearing can share the load evenly when bearing heavy loads, and the bearing capacity is effectively improved. At the same time, the use of high-quality materials and advanced manufacturing technology to ensure the bearing's wear resistance and extend the service life.Iko tapered roller bearings have high rotation accuracy and running stability.

Product Description:Hot-rolled carbon steel coils are made by rolling billets at high temperatures (usually heated to around 1000-1250 °C). Widely used in the manufacture of various mechanical parts, such as shafts, gears, connecting rods and so on.

The structure of Koyo tapered roller bearings mainly includes an outer ring, an inner ring, a rolling body (roller) and a cage. The rolling element is located between the inner ring and the outer ring and is kept in the specified axial position by the cage. The contact Angle between the inner ring and the outer ring is generally between 10° and 30°, and different contact angles will affect the bearing capacity and speed limit.

NSK automotive hub bearing is a key component used to support the rotation of automotive wheels. It uses high-quality bearing steel materials and advanced manufacturing processes to ensure the durability and performance stability of the bearing. NSK automotive hub bearings are usually composed of inner and outer rings, bearing balls (rollers), cages, sealing rings, etc. They can withstand the weight of the vehicle, reduce friction, improve rotation efficiency, and resist vibration and impact forces to ensure safety and stability when the vehicle is running.

Thrust ball bearings are produced as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.Thrust ball bearings are separable, the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit.
