Rolling device, the first will be fixed on the tank shell dial gauge face, the head of the table to touch the ring raceway of the bearing shaft bearing top migration transition, while migration shift while viewing the dial gauge pointer, if the pointer deflection, stating shaft ring and the shaft is not perpendicular to the middle line. If the tank shell hole deeper, longer dial gauge head can also be used to hone. This is a very good temper shaft ring and shaft middle line vertical approach. Koyo bearing device installed backwards, not only bearing is not working properly, and each joint surface would be subjected to severe wear. Because shaft ring and seat ring and the difference is not very obvious, the assembly should be presumptuous special careful not render upside down. Device should be precise division can take the initiative to adapt its seat rolling rolling, make sure to scroll down raceway body is located. In addition, self-aligning ball bearing race with the bearing hole should be left between 0.2-0.5mm gap for the compensation of machining parts, fixtures imprecise constitute an error when running the center-bearing rings shift, this gap can be adjusted to ensure that their initiative, avoid touching the friction to operate normally. Otherwise, it will cause serious damage bearings.

     1 foot race detection method commonly used bearing type: rolling bearings, plain bearings, wheel bearings, spherical bearings, thrust ball bearings, one-way bearing, full complement cylindrical roller bearings, thrust roller bearings, linear motion bearings.
For larger diameter bearings, a larger gap to narrow feeler with direct detection. For smaller diameter Koyo bearings, the gap is small, inconvenient with a feeler, but bearing backlash, we must use the proper thickness feeler.

     2, the pressure of lead detection method

     Lead was detected with the pressure bearing clearance with a feeler Jiao detection accuracy, but more trouble. Should be used for detecting soft aluminum wire, the diameter should not be too large or too small, and most preferably a diameter of 1.5 to 2 times the gap, the actual work is usually detected with a soft wire.

     Detection, the first Koyo bearing cap open, choose the appropriate diameter lead wire, be cut into 15 to 40 mm long pieces, placed on the upper and lower bearing journal at the interface, cover bearing cover, fasten the specified torque bolts, then loosen the bolts, remove the bearing cap, with a micrometer detection flattened lead wire thickness, calculated bearing tip clearance averages. If the top clearance is too small, to the upper and lower surface of the tile with padded. If too large, cut mats, scraping or re-poured watts.

     Koyo Bearings After installation, in order to check for proper installation, operation should be checked. Small machines can be rotated by hand to verify rotate smoothly. Check the project due to nick, indentation caused by dysfunctional, because poor installation, mount the torque generated by poor processing unstable, because clearance is too small, the installation error, seal friction torque caused by too large and so on. Without exception, you can begin powering.
