SET2520 Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove raceway geometry is optimized to support significant radial dynamic load ratings of 204 lbf, providing robust performance in demanding applications.
- Precision & Smooth Operation: Manufactured to ABEC-1 tolerance class with tight bore, outer diameter, and width tolerances, ensuring minimal runout and vibration for smooth, precise rotation.
- Corrosion Resistance: All components, including rings, balls, and the stainless steel cage, are made from stainless steel, making the bearing suitable for harsh environments and washdown applications.
- High-Speed Capability: With a limiting speed of 9,000 rpm, this bearing is capable of operating in high-velocity scenarios, supported by its stable stainless steel cage and optimized internal geometry.
- Compliance & Versatility: The bearing is compliant with ROHS and REACH regulations and operates effectively across a broad temperature range from -86 to 230 °F.
SET2520 Bearing Typical Application Areas
- Precision Instruments and optical devices requiring compact, high-tolerance components.
- Small Electric Motors and miniature gearboxes where space and weight are critical.
- Medical Equipment such as surgical hand tools and dental drills, benefiting from corrosion resistance.
- Office Automation Equipment including printers and scanners.
- Robotics and automation arms, particularly in joint and pivot points.
