61802-2Z Bearing Product Overview & Core Advantages
The 61802-2Z is a miniature deep groove ball bearing designed for applications demanding compact size, reliable performance, and low maintenance. As a single row bearing with shielded construction (2Z), it offers effective protection against contamination while retaining lubrication. Its primary strength lies in handling radial loads efficiently within a minimal cross-section, making it ideal for space-constrained, high-speed mechanisms. Manufactured to P6 tolerance class, it ensures precise operation and consistent performance in demanding environments.
61802-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 61802 | Basic bearing series designation for a metric, single row deep groove ball bearing. | Defines the core dimensions: 15mm bore, 24mm OD, 5mm width. |
| -2Z | Bearing is equipped with shields on both sides. | Provides effective contamination protection, retains lubricant, and supports a maintenance-free design. Not designed for high-speed contact. |
61802-2Z Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a 5mm width and weight of just 0.0073 kg, this bearing is engineered for applications where space and weight are critical constraints.
- Shielded for Protection & Longevity: The stainless steel shields (2Z) protect the internal rolling elements from dust and debris, while effectively retaining the pre-applied grease lubrication. This combination significantly extends service life and enables maintenance-free operation.
- High-Speed Capability: Featuring a stainless steel cage and optimized internal geometry, the bearing supports a limiting speed of 30,000 rpm, making it suitable for high-speed spindles and miniature motors.
- Precision Performance: Manufactured to P6 tolerance and standard CN radial internal clearance, it delivers precise running accuracy, low noise, and low vibration, which is crucial for sensitive instrumentation.
- Robust Material Construction: Rings and balls made from chrome steel provide high load capacity and durability, with a dynamic load rating of 427 lbf and a static load rating of 247 lbf.
61802-2Z Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle support in miniature DC motors, stepper motors, and fan motors.
- Precision Instruments: Used in optical encoders, medical devices, and laboratory equipment where low noise and high-speed precision are required.
- Office Automation Equipment: Critical component in printers, scanners, and copiers.
- Robotics and Automation: Suitable for joints, guides, and small drivetrains in compact robotic systems.
- Consumer Electronics: Found in computer hard disk drives, drones, and small power tools.
