SF693 Bearing Product Overview & Core Advantages
The SF693 is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing with an open design, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its compact size (3mm bore, 8mm OD) and ABEC1 precision class make it an ideal choice for high-speed applications up to 54,000 rpm, providing a robust and durable solution for miniature mechanical systems.
SF693 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| SF693 | Standard model designation for this specific bearing size and configuration |
| Open | No seals or shields, allowing for high-speed operation and easy relubrication |
| ABEC1 | Standard precision tolerance class suitable for most industrial applications |
| MC3 | Standard radial internal clearance group (0.002-0.013mm) for general purpose use |
SF693 Bearing Structural Features & Performance Benefits
The SF693's deep groove raceway and optimized geometry enable efficient radial load distribution across all six stainless steel balls. The stainless steel cage ensures precise ball spacing and guidance, contributing to smooth operation at high rotational speeds. The open construction minimizes friction and heat generation, while the MC3 radial clearance provides optimal performance across a wide temperature range (-30° to 110°C). With a dynamic load rating of 96 lbf and static load rating of 23 lbf, this bearing delivers reliable performance in space-constrained applications.
