Koyo tapered roller bearing is a common rolling bearing, usually used in automobiles, mechanical equipment, wind turbines and other fields.

IKO is a well-known manufacturer specializing in the production of various types of needle roller bearings, and its needle roller bearing products enjoy a high reputation around the world. IKO's needle roller bearings have a variety of excellent characteristics, and the following will describe the characteristics and applications of its needle roller bearings in detail.First of all, IKO's needle roller bearings are made of high-quality materials, have extremely high wear resistance and corrosion resistance, and can operate stably in a variety of harsh environments.

Needle roller bearing is a common mechanical part, which is mainly used to support the movement of the rotating shaft. The working principle of the needle roller bearing is to use the rolling body (needle roller) to roll between the inside and outside, thereby reducing friction and resistance, so that the bearing can withstand larger loads and rotational speeds.The structure of the needle roller bearing is relatively simple, consisting of an inner ring, an outer ring, a needle roller and a cage.

The working principle of needle roller bearings is to use rolling friction to reduce friction and resistance. When the bearing is subjected to axial or radial load, the needle roller rolls between the inner and outer rings, thereby reducing friction and resistance.

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.

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.

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

Needle roller bearing is a common rolling bearing, using needle roller as the rolling body, can withstand the radial and axial load.Structure: Needle roller bearings are mainly composed of outer ring, inner ring, needle roller, cage and seal. The shape size of the needle roller bearing is small, saving space, suitable for limited space design.

One of the largest aspects of the needle curler bearing is the sketch of the needle roller. The needle roller has a smaller diameter than different sorts of rolling elements, so it can obtain a greater load carrying capability in a constrained space.

Single row angular contact ball bearings mainly used forundertaking combined load both from radius and axle andalso for pure axle load,rotator speed is high.Material of bearings is choosed on refining bearing steelGCr15 (100Cr6，SUJ2,S2100) and other type of bearingsteel,balls are adopting GCr15 (100Cr6，SUJ2,S2100) orceramic. The bearings are classified as 7000C (15°)70000AC(25°)、7000B (40) in accordance with theircontact angle,other bearings with different contact angular areavailable on request.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)G

The outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e.

Stamped outer ring needle roller clutch, commonly known as one-way bearing or one-way needle roller bearing,  is a single directional bearing composed of a thin-walled outer ring, cage, spring plate,  and needle roller that is stretched from an alloy sheet. It can be used as a converter, check device,  and overrunning clutch, and is widely used in fitness equipment, cash counting machines, washing machines,  fishing gear, toy cars, and other transmission parts that need to have a reverse stop function.

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.

Most products can be shipped same or next day.IKO needle roller bearings can be roughly divided into radial bearings and thrust bearings according to the direction of the load they can withstand.

NACHl's self-aligning roller bearings are a common and important industrial part, widely used in a variety of mechanical equipment and construction machinery. It is mainly composed of an outer ring, an inner ring, a roller, a cage and other components, and supports the rotating and swinging shaft through rolling friction. Aligning roller bearing has large radial load capacity and high axial load capacity, as well as excellent self-aligning performance, and can adapt to the relative tilt and axial change between shaft and seat when working.
