Product Details

A pillow block bearing unit is actually a variation of a deep groove ball bearing. Its characteristic is that the outer diameter surface of the outer ring is spherical, which can cooperate with the corresponding concave spherical surface of the bearing seat to play a centering role. 

However, the basic performance of the pillow block bearing unit should be similar to that of the deep groove ball bearing. However, since these bearings are mostly used for rough machining machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is poor in neutrality, or the shaft length is deflected greatly, the bearing itself is not accurate enough, and some structures are also relatively rough, so the actual performance of the general performance. The performance is compared with deep groove ball bearings and there should be a big discount. For example, insert ball bearings with ejector screws are used for through shafts with poor stiffness and high deflection. There are sealing rings on both sides of the bearing, which can strictly prevent the intrusion of dirt. Add the right amount of lubricant. No need to clean and add lubricant before installation. When the jacking screw at the protruding end of the bearing inner ring is fastened to the shaft, its allowable axial load should not exceed 20% of the rated dynamic load.

 pillow block bearing unit

The performance of the pillow block bearing unit with the eccentric sleeve is basically the same as that of the outer spherical ball bearing with the jacking screw, except that the jacking screw is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole self-aligning ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft or installed on the shoulderless optical shaft with the help of a sleeve, and the bearing clearance can be fine-tuned.

Pillow block bearing units include: UC200 series, diamond seat UCFL200 series, outer spherical bearing UC300 series, boss round seat UCFC200, UCT200 series eccentric sleeve outer spherical bearing SA200 series, high center vertical seat UCPH200 series, tapered inner diameter spherical ball bearing UK200 series, ferrule seat UCC200 series, vertical seat UCP200 row narrow vertical seat UCPA200 series, square seat UCF200 series.
