A: The 2200-820 is a precision roller bearing used in the sprocket or shaft assembly of Linear/OSCO MSG-A gate operators. The precision ground races reduce runout and ensure smooth, accurate rotation under load.
A: The MSG-A is a specific variant within the Linear/OSCO MSG (Medium Slide Gate) series. The 2200-820 is the correct replacement bearing for the MSG-A model and should not be substituted with bearings from other MSG variants without verification.
A: Both the 2200-789 and 2200-820 share the same 1 in ID x 2 in OD envelope, but the 2200-820 is specified as a precision roller bearing for the MSG-A while the 2200-789 is a sealed radial ground bearing for the MSG-D. They are application-specific and may differ in internal design and tolerance class.
A: Precision roller bearings carry higher radial loads with lower friction than standard ball bearings of the same size. For gate operators driving heavy gates at high duty cycles, this results in longer bearing life and more efficient operation.
A: Replace the 2200-820 bearing if you observe increased noise (rumbling, grinding), vibration from the sprocket area, excessive heat near the bearing housing, or visible damage such as pitting, flaking, or corrosion on the races.
