Features of pillow block 205 bearing

pillow block 205 features:

■With automatic centering function

The outer diameter of the bearing and the inner diameter of the bearing seat are spherically matched, and there is an automatic alignment function between the two, which can compensate for axis misalignment and deformation of the installation bottom surface caused by installation errors.

■Large load capacity

Since the internal structure of the outer spherical ball bearing is the same as that of the 6200 and 6300 series deep groove ball bearings, the pillow block 205 can not only bear radial loads, but also large axial loads. At the same time, the bearing has low operating noise.

■Long service life

Pillow block 205 is usually used in harsh working environments such as mud, dust, moisture and high temperature. The grease inside the bearing will deteriorate in a short period of time. Therefore, it is necessary to grease and re-lubricate the seated spherical ball bearings at appropriate intervals, and replace the deteriorated grease with fresh grease. Cast iron outer spherical ball bearings are equipped with oil nozzles and can be re-lubricated to ensure perfect performance and long service life in any working environment.

■Excellent sealing performance

Both sides of pillow block 205 are sealed with heat-resistant and oil-proof rubber sealing rings and steel plate dust covers. The dust cover is assembled on the outer diameter of the bearing inner ring and rotates together with the inner ring. It can effectively prevent external foreign matter from entering the inside of the bearing and protect the bearing against external pressure. This combined seal consisting of a sealing ring and a dust cover can prevent Mud, dust, and moisture enter the inside of the bearing, and at the same time, it prevents the grease inside the bearing from leaking out. This enables the bearings to maintain perfect working performance even in harsh working environments.

■Solid bearing seat

The cast iron seat has an integral seat structure. The bearing seat has excellent rigidity, which prevents the bearing from deforming during assembly. The bearing seat is durable under any working conditions.

■pillow block 205 can be easily locked on the shaft

There are three ways to lock the bearing on the shaft. The commonly used method is to lock the two set screws on the extended end of the inner ring. You can also use an adapter sleeve or eccentric sleeve to lock. These three methods can easily lock the bearing on the shaft.

■pillow block 205 inner ring undergoes special heat treatment

The inner ring channel and the parts around it that need to be hardened are normally quenched, and the extended end of the inner ring where the set screw is mounted is partially tempered at high temperature to maintain toughness and impact resistance. After local high-temperature tempering around the screw holes in the inner ring, the bearing obtains better performance, which can prevent the screws from loosening during the operation of the bearing. At the same time, tightening the screws very tightly will not cause the inner ring to burst.

■Unique design to prevent outer ring from rotating

The outer ring of pillow block 205 is equipped with a unique stop pin (ball), which allows the bearing to self-align and prevents the outer ring from rotating, extending the service life of the bearing.

■Bearings and bearing seats are completely interchangeable

The bearings and bearing seats are precision machined. The bearings and bearing seats are completely interchangeable, and the bearings can be easily replaced at any time.

■Easy to install

Pillow block 205 has been pre-injected with enough high-quality grease, and the seated spherical ball bearing can be installed directly on the shaft. This prevents harmful substances from entering the inside of the bearing during the installation of the bearing unit.
