Bower MR1209 Bearing

MR1209 is a Bower M Series separable inner ring with one rib, designed for use with 1209 cylindrical roller bearings. It features a 45 mm bore, 59.03 mm outside diameter, and 19 mm overall width, with a round bore and a hardened alloy steel construction. The part is precision-ground and delivered without rollers, providing a precise seating surface that simplifies maintenance by allowing the inner ring to be replaced or serviced without removing the entire bearing assembly. The MR1209 is a separable inner ring in the M Series, featuring a single rib to interface with the 1209 cylindrical roller bearing, and it is intended specifically for use with 1209 bearings, ensuring accurate alignment and load distribution when assembled. Manufactured to tight tolerances, this inner ring relies on hardened alloy steel to resist wear in typical mechanical systems.
