How To Install A Pillow Block Bearing
Installation of outer spherical bearing:
1. Before installing the bearing on the shaft, you must first unplug the fixing pin of the bearing jacket, and at the same time polish the surface of the journal smoothly, and apply oil to the journal to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft).
2. Apply lubricating oil on the mating surface of the bearing seat and bearing, and install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location for installation.
3. Do not tighten the bolts that secure the bearing seat, and allow the bearing housing to rotate in the bearing seat. Also install the bearing and seat on the other end of the same shaft, rotate the shaft a few times, and let the bearing itself automatically find its position. Then tighten the bearing seat bolts.
4. Install eccentric sleeve. Put the eccentric sleeve on the eccentric step of the bearing inner sleeve first, and tighten it by hand in the direction of rotation of the shaft. Then insert the small iron rod into or against the counterbore on the eccentric sleeve. Hit the small iron rod with a hammer along the axis of rotation. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.
addition, it is more likely to happen in winter. When bearing pure radial load, it is easy to happen in occasions with large radial clearance, and it is easy to happen in a specific speed range with the size of the pillow block bearing. It will occur continuously and intermittently. The outer ring raceway adopts a special processing method to prevent the occurrence of rolling noise. This type of bearing can be selected when necessary, or the radial clearance of the bearing can be appropriately reduced, the use of high-performance grease and the rigidity of the parts matching the bearing can be improved .
MVPS BEARINGS can produce different pilow block bearing such as UCP201,UCP202 ,for more informations just contact with us email@example.com
