| Seal Type | Open | Allows for high-speed operation and custom lubrication schemes. Requires a clean operating environment. |
| Inner Ring | Extended | Simplifies axial positioning and can act as a spacer, enhancing assembly efficiency. |
| Tolerance Class | ABEC1 | Defines standard precision levels for bearing dimensions and running accuracy. |
| Internal Clearance | MC3 | Specifies a radial internal clearance range suitable for general applications. |
SFRW168 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and durability in harsh environments, with an operating temperature range of -86 to 230 °F.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized for efficient radial load support, ensuring stable operation.
- High-Speed Capability: The open design, combined with a stainless steel cage and 11 precision balls, enables a high limiting speed of 43.2 krpm, making it a capable high-speed bearing.
- Precision Engineering: Adherence to ABEC1 tolerances and controlled radial internal clearance (0.00008" to 0.0005") ensures low vibration and noise, contributing to the bearing's precision performance.
- Compact and Lightweight: With an overall weight of just 0.73 g and compact bearing dimensions (0.25" bore x 0.375" OD), it is ideal for space-constrained and weight-sensitive designs.
SFRW168 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications, including:
- Precision Instruments and Medical Devices: Where corrosion resistance, compact size, and smooth operation are paramount.
- Small Electric Motors and Gearboxes: Utilizing its high-speed capability and radial load capacity.
- Food and Beverage Processing Equipment: Benefiting from the hygienic properties of stainless steel.
- Office Automation Equipment: Such as scanners and printers, requiring reliable, long-life ball bearings.
- Robotics and Miniature Actuators: Where its lightweight and precision characteristics are critical for performance.
