61826 INA deep groove ball bearing

INA 61826 Thin Section Deep Groove Ball Bearing (ISO 10 Series)

The INA 61826 is a high-specialty rolling component from the thin-section series, engineered for applications where installation space is strictly limited. With a bore diameter of 130 mm, its outer diameter is only 165 mm, and its width is 18 mm. This geometry allows the bearing to be mounted on thick shafts with a minimal increase in housing dimensions. The open design facilitates free lubricant circulation, aiding effective heat dissipation in high-dynamic systems.

Application

• Automation & Robotics: Rotation axis support for large industrial robots and manipulators.
• Precision Machine Tools: Support for spindles and rotary tables requiring large shaft hollows.
• Aerospace Industry: Control mechanisms, radar, and scanners where weight reduction is vital.
• Medical Equipment: Large diagnostic apparatus (e.g., CT scanners) requiring smooth rotational motion.
• Renewable Energy: Compact shaft support in generators and wind turbine pitch mechanisms.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 61826.
• Dimensions: 130 mm (ID) x 165 mm (OD) x 18 mm (Width).
• Internal Clearance: CN (Normal) – optimal for standard operating conditions.
• Cage: Precision pressed steel, ensuring stable ball guidance.
• Design: Open type (no seals), cylindrical bore.

Features and Benefits

• Extreme Space Efficiency: Very slender profile allows for significant miniaturization of bearing arrangements.
• Low Weight: Drastic reduction in steel volume compared to standard series lowers the overall machine weight.
• High Running Precision: Manufactured to SCHAEFFLER standards, ensuring minimal radial run-out and quiet operation.
• Low Friction: Precision-ground raceways minimize resistance, leading to high energy efficiency.
• Fatigue Life: Heat-treated steel with the highest metallurgical purity for long-term reliability.

Why Choose This Product

By choosing the INA 61826 bearing, you are investing in a premium product that addresses space-constraint challenges in your machinery. In 130 mm diameter applications, manufacturing precision is critical to avoiding vibration and premature wear. With the thin-section series from Schaeffler, you can design lighter, more modern, and energy-efficient equipment without compromising on the legendary reliability of German engineering.
