pillow block cast housing mounted bearings

Spherical bearing with seat is a kind of bearing unit that combines rolling bearing and bearing seat. Most rolling bearings make the outer diameter of the outer ring of the bearing core into a spherical surface, and install it together with the bearing seat with spherical inner hole. Various structural forms, good versatility and interchangeability. At the same time, this type of bearing also has a certain self-alignment in design, easy to install, and has a double-structured sealing device, which can work in harsh environments. The bearing seat is generally made of cast molding.

Features of pillow block cast housing mounted bearings

1. 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 centering function between the two, which can compensate for the misalignment of the axes caused by the installation error and the deformation of the installation bottom surface.

2. Large load capacity

Because 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 outer spherical ball bearing with seat can not only bear radial load, but also bear certain axial load. At the same time, the bearing has low working noise.

3. Long service life

Pillow block cast housing mounted bearings are usually used in harsh working environments such as mud, dust, humidity and high temperature, and the grease inside the bearing will deteriorate in a short time. Therefore, it is necessary to adjust the outer spherical ball bearing with a seat at an appropriate time interval. Grease and re-lubricate, replace the deteriorated grease with fresh grease. FS with cast iron insert ball bearings are equipped with grease nipples, which can be re-lubricated to ensure perfect performance and long service life in any working environment. The grease can be selected from normal temperature, low temperature and high temperature according to the different ambient temperature used. The company’s standard product is the use of No. 2 lithium base grease, the service life of grease is shorter than that at normal working temperature. There is an oil groove on the outer ring of the bearing, which can better ensure that the grease can be smoothly injected into the bearing from the grease nipple.

4. Excellent sealing performance

pillow block cast housing mounted bearings have heat-resistant, oil-proof rubber sealing rings and steel plate dust-proof cover combination seals on both sidesSeal. 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 external pressure to protect the bearing. This combination seal composed of a sealing ring and a dust cover It can prevent mud, dust and moisture from entering the inside of the bearing, and at the same time, it can prevent the grease inside the bearing from leaking out. The bearing can maintain perfect working performance under harsh working conditions. Sealing form skeleton rubber sealing ring + retaining ring sealing form, the double-iron rubber ring (F) form, the triple-lip seal (R3) form for use in extremely harsh environments, and the crimping and gluing form suitable for SA/SB series, etc.

5. Sturdy bearing housing

pillow block cast housing mounted bearings. The bearing seat is an integral seat structure, the bearing seat has excellent rigidity, prevents the bearing from being deformed during assembly, and the bearing seat is durable under any working conditions. The bearing seat can be made of gray cast iron, ductile iron and cast steel and other materials.
