Description
Basic Parameters
In bearing 1204, “1”: Indicates that the bearing type is a self-aligning ball bearing. Self-aligning ball bearings are characterized by their two rows of balls and a spherical outer ring raceway, enabling them to automatically compensate for shaft misalignment or mounting errors. They can bear radial loads and moderate axial loads in both directions. “2”: Indicates the bearing’s diameter series code. The diameter series code represents the relative dimensions of the bearing’s inner and outer diameters. The 2 series typically signifies a light series, meaning the bearing has a relatively compact size while maintaining suitable load-carrying capacity for its internal diameter. “04”: Indicates the bearing’s inner diameter code. Following the standard rule (inner diameter = code × 5), the actual inner diameter of the 1204 bearing is 04 × 5 = 20mm. The model 1204 bearing does not explicitly indicate the tolerance grade, which is generally assumed to be grade 0, the normal precision level. This grade meets typical dimensional and rotational accuracy requirements for most general applications.
