61832 -C3 INA deep groove ball bearing

INA 61832-C3 Thin Section Deep Groove Ball Bearing (ISO 10 Series)

The INA 61832-C3 is a high-performance rolling component from the thin-section series, engineered for applications with strictly limited installation space. Featuring a 160 mm bore, its outer diameter is only 200 mm, with a width of just 20 mm. The standout feature is the increased internal clearance (C3), which prevents bearing seizure during high-speed operation or significant temperature differentials between the rings.

Application

• Robotics & Automation: Main rotation axes for industrial robots and large-scale manipulators.
• CNC Machine Tools: Support for spindles and rotary tables requiring large shaft throughput.
• Aerospace: Positioning mechanisms, scanners, and radar systems.
• Medical Equipment: Large diagnostic devices (e.g., CT scanners) requiring smooth motion with large bore diameters.
• Energy Sector: Compact shaft support in generators and wind turbine components.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 61832-C3.
• Dimensions: 160 mm (ID) x 200 mm (OD) x 20 mm (Width).
• Internal Clearance: C3 (Greater than Normal) – ideal for high-heat environments.
• Cage: Precision pressed steel cage.
• Design: Open type, cylindrical bore.

Features and Benefits

• Extreme Space Efficiency: The exceptionally slender profile of the 618 series allows for significant machine housing miniaturization while maintaining shaft rigidity.
• C3 Clearance Advantage: Radial clearance margin eliminates the risk of seizure during thermal expansion of the shaft.
• Low Mass & Inertia: Thinner rings and smaller balls reduce the torque required for machine start-up.
• Low Frictional Torque: Precision raceways minimize resistance, increasing energy efficiency.
• SCHAEFFLER Engineering: Use of high-purity steel ensures exceptional fatigue life and reliability.

Why Choose This Product

By choosing the INA 61832-C3 bearing, you are investing in a product that solves design challenges where standard bearings are too bulky and heavy. In 160 mm bore applications, INA's manufacturing precision and C3 clearance are critical for avoiding heat-related failures. With this thin-section series, you can design lighter and more modern equipment while relying on the uncompromising quality of an industry leader.
