Description

Basic Parameters

In bearing 61802, “6”: Indicates that the bearing type is a deep groove ball bearing, which is highly common with a simple structure and easy usability, mainly designed to bear radial loads and some axial load. “18”: The digit “8” here represents the bearing’s diameter series code, with the 8 series typically denoting the extra light series, indicating the bearing’s inner and outer diameter dimensions belong to the extra light category. “02”: Indicates the bearing’s inner diameter code. For inner diameter codes below 04, specific rules apply: 00 = 10mm, 01 = 12mm, 02 = 15mm, and 03 = 17mm. Thus, the inner diameter of the 61802 bearing is 15mm. The tolerance grade is not explicitly shown in the model but is generally assumed to be grade 0, the normal precision level, representing standard dimensional and rotational accuracy. In summary, the bearing model 61802 signifies a deep groove ball bearing, extra light series (diameter series 8), inner diameter of 15mm, and normal precision level, suitable for various applications including high-speed transmission and scenarios requiring some axial load capacity.

Working Principle

The working principle of the Deep Groove Ball Bearing 61802 revolves around its fundamental structure and the mechanical interaction of its components. It consists of an inner ring, an outer ring, a set of precision-grade steel balls, and a retainer (cage). The inner and outer rings feature continuous, semi-circular raceways that form a deep groove path for the balls.
When the bearing is in operation, the steel balls roll between the inner and outer ring raceways, converting sliding friction into minimal rolling friction. This allows the bearing to efficiently transmit radial loads (forces perpendicular to the shaft) and moderate axial loads (forces parallel to the shaft). The deep groove design provides additional contact area between the balls and raceways, enhancing the bearing’s capacity to handle combined radial-axial loads and misalignment tolerance.
The retainer separates the balls evenly, preventing direct contact and reducing friction while maintaining consistent spacing for smooth, high-speed rotation. In the 61802 model, the extra-light diameter series (18) and compact dimensions (15mm ID, 24mm OD, 5mm width) optimize it for applications requiring lightweight construction and space efficiency. The standard precision grade (Grade 0) ensures reliable dimensional accuracy, making it suitable for general-purpose high-speed scenarios, such as small motors, precision instruments, or automation systems, where low noise and stable rotational performance are critical.

Product Application

The Deep Groove Ball Bearing 61802 (61802) is widely applied in various industries and mechanical systems due to its compact design, high-speed capability, and ability to handle light to medium radial loads with some axial load capacity. Its extra light diameter series (18) and 15mm inner diameter make it ideal for space-constrained applications requiring lightweight construction. Common uses include small electric motors (e.g., in household appliances like fans, blenders, and power tools), precision instruments (such as optical equipment and measurement devices), automotive auxiliary systems (e.g., electric power steering motors, air conditioning compressors), office machinery (printers, copiers, and scanners), textile machinery (spinning and weaving equipment with high-speed rotating components), and automation systems (robot joints, conveyor belts, and linear motion guides). Additionally, it is suitable for medical devices (low-noise applications like diagnostic equipment) and consumer electronics (small gearboxes in drones or portable electronics). The bearing’s standard precision grade (grade 0) ensures reliable dimensional accuracy and rotational smoothness in general-purpose applications, while its simple structure enables easy installation and maintenance across diverse operational environments.
