12L30R

12L30R refers to a specific type of bearing, commonly found in industrial applications. The designation breaks down into key characteristics. The '12' typically indicates the bore diameter in millimeters, though specific bearing series might have variations in this convention. The 'L' often denotes a light series of bearing, suggesting a thinner wall thickness or lighter load capacity compared to standard or heavier series. The '30' usually signifies the outside diameter of the bearing, also in millimeters. Finally, the 'R' can indicate specific features such as a flanged outer ring or other specialized design elements that differentiate it from a standard configuration.

Bearings like 12L30R are precision components designed to reduce friction and facilitate rotational movement between two parts. Their construction usually involves an inner ring, an outer ring, and rolling elements (balls or rollers) held in place by a cage. The precise dimensions and series of a bearing are crucial for its performance and suitability for a given application, which might include pumps, motors, machinery, or other rotating equipment where efficient and reliable motion is required. The exact specifications and intended use of a 12L30R bearing would be detailed in the manufacturer's product catalog.
