SF602zz Bearing Product Overview & Core Advantages
The SF602zz is a miniature metric single row deep groove ball bearing designed for compact applications requiring high precision and reliable performance. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently within a very small envelope, making it ideal for applications where space is at a premium and operational reliability is critical. The inclusion of shielded seals (zz) helps protect the bearing's interior from contaminants.
SF602zz Bearing Model Code Explained, Specifications & Naming Convention
- SF602: Indicates a specific series of miniature deep groove ball bearings with a 2mm bore, 7mm outside diameter, and 3.5mm width.
- zz: Denotes that the bearing is equipped with shielded seals on both sides. These non-contact shields help retain lubrication and exclude larger contaminants without significantly increasing rotational torque.
SF602zz Bearing Structural Features & Performance Benefits
Compact & Lightweight Design: With a total weight of just 0.73g and minimal cross-section, this bearing is engineered for miniaturized assemblies and portable devices.
Corrosion Resistance: The use of stainless steel for all core components ensures reliable operation in humid or mildly corrosive environments, enhancing the bearing's service life.
Radial Load Capacity: The deep groove raceway and complement of 7 balls are optimized to support the specified radial dynamic load rating of 66 lbf and radial static load rating of 21 lbf.
Precision & Speed: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, it provides consistent performance and can operate at a limiting speed of 54,000 rpm.
Shielded Protection: The zz shields offer a basic level of protection against dust and other particulates, helping to maintain performance in less-than-ideal conditions.
SF602zz Bearing Typical Application Areas
This bearing is commonly specified in applications requiring small bearing dimensions and reliable rotation, including:
- Small DC Motors and Gear Motors
- Precision Instruments and Optical Encoders
- Medical Devices and Dental Handpieces
- Small Fans and Blowers
- Radio-Control Models and Drones
- Office Automation Equipment
