After installing the bearing, in order to check that the installation is correct, to run checks. Small machine can rotate to confirm whether it rotates smoothly. Check the project due to foreign bodies, scar, indentation cause to seize up, poor installation, mounting bad moment of instability arising from processing, as the clearance is too small, installation error, caused by seal friction torque is too large, and so on.
(1) as possible to force through the axis of the self-aligning ball bearing, this requires that the point of force application symmetrically and evenly smooth through the sphere, or parallel to the axis force.
(2) the size of the force should be smooth and uniform, not shocks, this requires the use of oil or energy tool for smooth tension or pressure, would certainly have when the hammer is used, also do not fall through the copper sleeve soft scrap metal to be buffered, strike force as gentle as possible. It is best to use copper or copper hammer blow.
(3) avoid the rolling force, this calls for Assembly, disassembly and inner ring (shaft), through the inner force, when assembling and dismantling the outer ring) by applying pressure on the outer ring.
(4) drag force to be continued to the extent, for example in the housings to just stop when filled to the correct location of the bearing force to ensure ring (washer) faces arriving by the bore or axial abutment face, cannot be squeezed too tightly and if it is not put in place.
Large machinery cannot be rotated manually, so no load starting immediately after cutting off power, machinery idle, check for vibrations, noise, contact rotating parts, and so on, after confirming that without exception, into the power running.
