SIBCO Bearing

Rolling sound and its control method of spherical bearings with seats Rolling sound is a harsh metal friction sound that can occur in cylindrical roller bearings in all situations, mostly occurring in larger grease lubricated bearings, but more likely to occur in lubricating grease with degraded base oil performance, and almost never occurs during oil lubrication.

In addition, it is more prone to occur in winter when subjected to pure radial loads, and is more likely to occur in situations with large radial clearance. Depending on the type and size of the outer spherical bearing with seat, it is more likely to occur within a specific speed range, both continuously and intermittently. Special processing methods can be used for the outer race raceway to prevent rolling noise. If necessary, this type of bearing can be selected, or the radial clearance of the bearing can be appropriately reduced, high-performance lubricating grease can be used, and the rigidity of the parts matched with the bearing can be improved.

(1) Proper installation is crucial for the use of spherical bearings with seats. I hope everyone can use the correct installation method in their future use.

(2) During installation, mechanical, heating, or hydraulic methods can be selected based on its type and size. The force applied to the outer spherical bearing with seat during installation must not be transmitted from one bearing ring to another through the rolling elements, otherwise it may cause damage to the raceway. Under no circumstances should the bearing ring, cage, rolling element, or seal be directly struck.

(3) Install eccentric sleeve. First, insert the eccentric sleeve onto the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of the shaft rotation Then insert or press the small iron rod into the counterbore on the eccentric sleeve Use a hammer to strike the small iron rod in the direction of axial rotation Install the eccentric sleeve firmly, and finally tighten the hexagon socket screw on the eccentric sleeve.

(4) Do not tighten the bolts that fix the bearing seat yet, but allow the outer spherical bearing sleeve with the seat to rotate inside the bearing seat. Tighten the bearing seat bolts again. Install the other end bearing and seat on the same shaft, rotate the shaft a few times, and let the bearing automatically align itself.

(5) Apply lubricating oil to the mating surface between the bearing seat and the bearing, and install the bearing into the bearing seat. Then fit the assembled bearing and bearing seat together onto the shaft Push to the desired location for installation. Disassembly and maintenance techniques for spherical bearings with seats, as well as technical points for bearing installation.

(6) Before installing the outer spherical bearing with seat on the shaft, the fixing pin of the bearing sleeve must be removed first, and the surface of the shaft neck must be polished smooth and clean. Oil should be applied to the shaft neck for rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft).
