S602 Bearing Product Overview & Core Advantages
The S602 is a metric miniature ball bearing designed for applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing, it is primarily engineered to support radial loads efficiently. Constructed entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for various demanding environments. Its small size, with a 2 mm bore and 7 mm outside diameter, combined with an ABEC1 tolerance class, provides a cost-effective solution for high-speed operation and general precision applications.
S602 Bearing Model Code Explained, Specifications & Naming Convention
- S: Typically denotes a bearing with a stainless steel construction.
- 60: Indicates the bearing series, defining the cross-sectional dimensions and load characteristics.
- 2: Specifies the bore diameter code. In this case, '2' corresponds to a 2 mm bore.
- Open (No Seal Suffix): The absence of a seal suffix (e.g., -2Z or -RS) indicates an open bearing, which allows for higher limiting speeds but requires an external sealing solution if used in contaminated environments.
S602 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The raceway design enables smooth operation and effective handling of radial loads.
Full Complement Stainless Steel: The rings, balls, and cage are manufactured from stainless steel, ensuring consistent performance, corrosion resistance, and compatibility with a wide temperature range (-30° to 110 °C).
High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 54,000 rpm, making it an excellent choice for high-speed applications.
Precision & Clearance: Manufactured to ABEC1 precision class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring reliable and consistent operation.
Note on Lubrication: This is an open bearing and requires lubrication for operation. The specific lubricant must be selected based on the application's speed, temperature, and environmental conditions.
S602 Bearing Typical Application Areas
The S602 miniature bearing is ideally suited for a wide range of small-scale, precision machinery and devices, including:
- Small DC Motors and Stepper Motors
- Precision Instruments and Optical Encoders
- Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Radio-Control Models and Drones
- Small Pumps and Fans
