HR6209 509 Bearing Technical Description

HR6209 509 is a single-row deep groove ball bearing with a 45 mm bore diameter, 85 mm outside diameter and 19 mm width. It is used at the primary pulley front in QR019CHA / QR019CHB applications.

Its deep raceway geometry supports radial loading together with axial loading in either direction while maintaining smooth shaft rotation. At the specified installation position, the bearing supports the rotating component and maintains alignment within the gearbox assembly.

Before replacement, confirm the exact HR6209 509 designation, 45x85x19 mm boundary dimensions, primary pulley front and QR019CHA / QR019CHB equipment code. Verify the cross references HR6209 / 019CHA-1502524 / 789279A against the removed bearing or the transmission parts list.
