SKF 6203 AY C78, a single-row deep groove ball bearing in the 6200 light dimension series. Bore: 17 mm. Outside Diameter: 40 mm. Overall Width: 12 mm. Closure Type: open both faces. Rolling Elements: steel balls. Number Of Rows: 1. Series: 6200. Dynamic Load Rating: 9.56 kN. Static Load Rating: 4.75 kN. Internal Clearance: CN. Country of origin as marked on the carton: United States.
6 — single-row deep groove ball bearing, the radial ball type that carries radial load with a useful share of thrust in either direction.
2 — the 02 light dimension series, which sets the 40 mm outside diameter and 12 mm width against the 17 mm bore.
03 — the bore code, 03 x 5 = 17 mm.
Dynamic Load Rating: 9.56 kN. That is the constant radial load at which the bearing reaches one million revolutions of basic rating life, and it is the figure a life calculation starts from. Static Load Rating: 4.75 kN. That is the load the raceways carry at rest or at very low speed before permanent indentation matters. Internal Clearance: CN, the normal group, which suits a standard interference fit on the shaft and a normal running temperature. The open execution takes lubricant from the housing, can be flushed and re-greased in service, and adds no seal drag, so it runs cooler and faster than a sealed build of the same size.
Bore: 17 mm, cylindrical. Outside Diameter: 40 mm. Overall Width: 12 mm. The bearing seats between a shaft shoulder and a housing shoulder on both rings; both rings are non-separable, so it is pressed on and out as one unit.
Unit Quantity: 1 Pc. Supplied as a single bearing.
Manufacturer part number variants recorded on this listing: 6203AYC78, 6203 AY C78, 6203-AY-C78, 6203P5, 6203-P5 and M203K. Any 17 x 40 x 12 mm deep groove ball bearing in the 6203 envelope interchanges dimensionally. Closure, internal clearance group and cage execution are what decide whether a candidate is a like-for-like substitution rather than only a dimensional one.
