SKF 6217-JEM Single Row Deep Groove Ball Bearing

SKF 6217-JEM is a single-row deep groove ball bearing with an 85 mm bore, 150 mm outside diameter, and 28 mm width. It is an open bearing (no shields or seals) whose cage is pressed steel (the J in JEM) and is intended for electric motor applications (EM denotes electric motor quality). In SKF's aftermarket designation, the JEM suffix accompanies features such as C3 radial internal clearance and QE6 quiet-running designation, supporting reliable operation in precision machinery. The bearing is commonly used as a replacement in motor housings and similar equipment requiring a standard 85x150x28 mm bearing in open form; the JEM marking is typically found on packaging rather than on the race itself. This combination of robust construction and precise tolerances provides long service life under typical industrial loads and speeds encountered in electric motor-driven systems.
