Fafnir MM209KMBR super-precision spindle deep groove ball bearing, built by The Timken Company. Series: 200K. Bore: 45 mm. Outside Diameter: 85 mm. Bearing Width: 19 mm. Precision Class: ISO P4S (ABEC 7/9). Cage Material: Bronze. Cage Type: Machined, land riding. Rolling Elements: steel balls. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1. Design Units: Metric. The ISO envelope is 6209.
MM is Timken’s super-precision spindle prefix and carries ISO P4S accuracy. 209 in the 200K series is the 6209 envelope. K identifies the spindle deep groove family. MBR is the machined bronze cage.
A Conrad deep groove bearing carries radial load and axial load in either direction, which is what makes it the usual choice for the rear, floating position of a machine-tool spindle where the shaft has to grow with temperature. P4S accuracy holds running and axial runout to super-precision limits, so the bearing locates the shaft closely enough for a ground finish. A machined bronze cage tolerates higher temperature and marginal lubrication than a phenolic cage and holds its form under shock loading.
Unit Quantity: 1 Pc. Arrangement / Configuration: Single. Rows per Set: Single.
Max Shaft Fillet Radius: 1 mm (0.039 in). Outer Ring To Clear Radius: 1 mm (0.039 in). Shaft Backing Shoulder Diameter: 52.3 mm (2.060 in). Housing Backing Shoulder Diameter: 78.2 mm (3.080 in).
Timken base designation: MM209K. ISO envelope: 6209. Searchable forms of the designation: MM209KMBR, MM-209-K-MBR, MM 209 K MBR.
