How to use
Handle the steel ball with clean gloves or tools to avoid contamination and surface damage. Verify the dimensional fit and clearance within the intended housing or race before installation. For bearing replacement, remove the old ball(s), inspect the raceways and cages for wear, and install the new ball ensuring proper seating and lubrication as specified for the assembly. In valves or fittings, confirm compatibility with mating parts and apply recommended lubrication or anti-seize where applicable.
