# When to Coat a Supplied Bearing Versus Ordering a Factory-Insulated Unit

There are two honest ways to get an electrically insulated bearing. One is to buy a unit that was manufactured or converted as an insulated product from the start. The other is to keep a bearing you already purchased or had made to print, and ask a specialist to apply ceramic insulation to that part.

Coating the supplied bearing is usually the better path when the brand, the exact model, or a custom drawing is already fixed, and when the ring design can accept the added thickness. Ordering a factory-insulated bearing is often cleaner when you are still free to choose the part number and want a standard insulated catalogue item.

The decision turns on coating thickness and mounting tolerances as much as on price. If the finished dimensions cannot be held, coating is the wrong answer no matter how attractive it looks on paper. Shandong TFL Bearing Co., Ltd, at Room 501, Building 2, Lushang Phoenix Plaza, Tangye Middle Road, Licheng District, Jinan, Shandong, China, offers the coating route for eligible customer-supplied bearings and can also discuss a manufactured insulated bearing when that is the better fit.
