What is the shaft bearing definition of pillow block bearing?

Shaft bearing definition of outer spherical bearing has a wide inner ring deep groove ball bearing with a double-sided seal and a spherical outer cross section, and a bearing seat (cast iron seat or steel stamping seat). Its typical structure is shown in the figure below. The shaft bearing definition of bearing unit has a compact structure, self-aligning function, convenient installation and maintenance, complete sealing device, reliable sealing performance, and is suitable for a harsh working environment. Widely used in agricultural machinery, construction machinery, textile machinery, food processing machinery and conveyor belt systems.

shaft bearing definition of spherical bearing ball bearing characteristics
■With automatic self-aligning function:TheShaft bearing definition for outer diameter of the bearing and the inner diameter of the bearing housing are spherically matched, and the two have an automatic self-aligning function, which can compensate for the misalignment of the axis caused by the installation error and the deformation of the mounting bottom surface.

■Great load capacity:Since the shaft bearing definition of the outer spherical ball bearing is the same as that of the 6200 and 6300 series deep groove ball bearings, the shaft bearing definition of IB spherical ball bearing not only can withstand radial loads, but also can withstand large axial directions. load. At the same time, the bearing work noise is small.

shaft bearing definition Long service life:The shaft bearing definition of the ball bearing is usually used in harsh working environments such as dirt, dust, moisture and high temperature, and the grease inside the bearing will deteriorate in a short period of time. Therefore, it is necessary to relubricate the shaft bearing definition of the outer spherical ball bearing at appropriate intervals and replace the deteriorated grease with fresh grease. The cast shaft bearing definition of iron outer spherical ball bearings are equipped with grease nipples that can be relubricated to ensure perfect performance and long service life in any working environment

■ shaft bearing definition Excellent sealing performance:the shaft bearing definition of the outer spherical ball bearing has a heat-resistant, oil-proof rubber sealing ring and a steel plate dust cover combination seal on both sides. The dust cover is assembled on the outer diameter of the inner ring of the bearing and rotates together with the inner ring, which can effectively prevent external foreign matter from entering the inside of the bearing and can resist the external pressure to protect the bearing. The combined seal composed of the sealing ring and the dust cover can block Mud, dust, and moisture enter the inside of the bearing and prevent grease from leaking inside the bearing. The shaft bearing definition of bearings can maintain perfect working performance under harsh working conditions.

■ shaft bearing definition Sturdy bearing housing:the cast iron seat is a one-piece structure. The bearing seat is extremely rigid and prevents the bearing from being deformed during assembly. The bearing housing is durable under any working condition.

■ shaft bearing definition The Shaft bearing definition of bearing can be easily locked on the shaft:there are three ways to lock the bearing on the shaft. The common method is to lock the two setscrews on the extended end of the inner ring, or use the adapter sleeve or the eccentric sleeve to lock. All three methods can easily lock the bearing on the shaft.

■Special heat treatment of the inner ring of the bearing:the inner ring channel and its surrounding hardened part and the normal quenching, the inner end of the inner ring of the set screw are subjected to high temperature local tempering to maintain toughness and impact resistance. After local high temperature tempering around the inner ring screw hole, the bearing obtains better performance, which prevents the screw from being released during the operation of the bearing, and the screw is tightened tightly and does not cause the inner ring to burst.

■ shaft bearing definition Unique design to prevent rotation of the outer ring:the bearing outer ring is equipped with a unique stop pin (ball) that allows the bearing to automatically align and prevent the outer ring from rotating, resulting in longer bearing life.

■shaft bearing definition of the bearing and the bearing housing are completely interchangeable:bearings and shaft bearing definition of  are precision machined, bearings and housings are completely interchangeable, and bearings can be easily replaced at any time.

■Easy to install:the shaft bearing definition of the outer spherical ball bearing has been pre-filled with sufficient high-quality grease to mount the outer spherical ball bearing directly on the shaft. It is thus avoided that harmful substances enter the inside of the bearing during the installation of the bearing unit.

The shaft bearing definition of the spherical ball bearing is usually maintenance-free. The high-quality grease filled in the bearing during assembly can generally meet the service life of the bearing. However, if the working environment is bad, the bearing is running at high speed or the working temperature is above 70 °C, it is necessary to replenish the bearing grease. The shaft bearing definition of IB has a lubricating structure and a grease nozzle that is injected into the bearing housing by the oil gun. Enter the inside of the bearing through the oil groove and oil hole on the outer ring of the bearing.

The shaft bearing definition of the outer spherical ball bearing can withstand an initial angular error of no more than ±5°. However, if the grease needs to be replenished, the initial angular error is only ±2.5°, otherwise the oil hole on the outer ring will be covered.

The bearing capacity of the shaft bearing definition for radial spherical ball bearing is the same as that of the deep groove ball bearing, and the equivalent load is calculated in the same way as the deep groove ball bearing (see page 4). The axial load capacity depends on the inner ring and the bearing's robustness. Under normal circumstances, it should not be greater than 20% of its rated load. When the axial load is large, a strong device such as a shoulder should be added to the shaft.

When installing the shaft bearing definition of the outer spherical ball bearing, put the bearing on the shaft, first fix the bearing seat firmly on the bearing surface, and then fasten the bearing to the shaft. The method of fastening theShaft bearing definition of bearing to the shaft is: For a shaft bearing definition of a spherical ball bearing with a set screw, use a hexagon socket head wrench to lock the two setscrews on the wide inner ring of the bearing in place. For the outer spherical ball bearing with eccentric tightening sleeve, put the eccentric sleeve on the eccentric table of the inner ring of the bearing, tighten the eccentric sleeve in the direction of rotation of the shaft, and then tighten the set screw on the eccentric sleeve with a hexagon socket screw wrench.
