61852 INA deep groove ball bearing

INA 61852 Thin Section Deep Groove Ball Bearing (ISO 10 Series)

The INA 61852 is a specialized rolling component featuring a unique thin-section design. With a large bore diameter of 260 mm, its cross-section remains exceptionally small, allowing it to be mounted on thick shafts while minimally increasing the outer dimensions of the housing. This open-type model permits free circulation of lubricant (oil or grease), which is vital for systems requiring effective heat dissipation during continuous operation.

Application

• Robotics & Automation: Bearing support for the main rotation axes in large industrial robots and manipulators.
• Energy Sector: Compact shaft support in generators and wind power equipment.
• Machine Building: Rotary tables, winding drums, and large-scale printing machinery.
• Medical Industry: Diagnostic apparatus (e.g., CT scanners) requiring a large through-hole diameter.
• Aerospace: Precision control mechanisms and radar systems where weight reduction is critical.

Technical Specification

• Manufacturer: INA (Schaeffler Group - Germany).
• Designation: 61852 (according to DIN 625-1).
• Dimensions: 260 mm (ID) x 320 mm (OD) x 28 mm (Width).
• Internal Clearance: CN (Normal) – optimized for standard operating temperatures.
• Cage: Precision pressed steel.
• Design: Open type (no seals), cylindrical bore.

Features and Benefits

• Extreme Space Efficiency: The diameter-to-width ratio allows for significant miniaturization of bearing arrangements.
• Low Weight: Reducing the amount of steel compared to standard series (e.g., 62xx) lowers the moment of inertia.
• High Rigidity: Despite its slender profile, the high ball count ensures excellent radial and axial guidance.
• Running Precision: Manufactured to SCHAEFFLER standards, ensuring very low radial run-out and quiet operation.
• Fatigue Life: Heat-treated steel with the highest metallurgical purity for long-term reliability.

Why Choose This Product

By investing in the INA 61852 bearing, you are choosing a premium product from the rolling technology leader – the SCHAEFFLER Group. In applications with such a large bore (260 mm), manufacturing precision is critical to avoid vibration and premature wear. With the thin-section series, you can design lighter and more energy-efficient equipment without compromising on the reliability guaranteed by German engineering.
