This component isn’t just a part—it’s a guarantee of operational reliability and consistent drilling performance. Whether you’re engaged in underground mining, tunneling, or surface drilling, the 550 261 46 BEARING HF820 DRIFTER SANDVIK plays a vital role in minimizing machine downtime and extending the life of your drilling equipment.

Key Features and Specifications

• Part Number: 550 261 46

• Part Name: BEARING HF820 DRIFTER SANDVIK

• Material: High-strength bronze alloy, offering superior wear resistance and optimal lubrication retention

• Surface Finish: Precision-machined for minimal friction and extended durability

• Design Purpose: Serves as a radial bearing for internal rotation mechanisms within the HF820 drifter unit

• OEM Quality: Manufactured under strict OEM specifications to ensure dimensional accuracy and seamless fit

The 550 261 46 BEARING HF820 DRIFTER SANDVIK features a cylindrical bushing form with a finely honed internal diameter that allows for low-resistance rotation. The bronze construction offers high thermal conductivity and excellent resistance to deformation under pressure, making it ideal for long-duration drilling operations.

Compatible Sandvik Models

This bearing is designed to perfectly integrate with Sandvik HF820 series drifters, which are widely used in:

• Sandvik DX780

• Sandvik DX800

• Sandvik DP1100i

• Sandvik DX820i

• Sandvik Pantera DP1500i

These models are known for their superior penetration rates and reliability in harsh drilling environments, and the 550 261 46 bearing contributes significantly to this performance. It ensures smooth shaft rotation, minimizes vibration, and reduces wear on adjacent components—ultimately enhancing overall machine longevity.

Application Areas

The 550 261 46 BEARING HF820 DRIFTER SANDVIK is a core component within the rotary and percussion sections of the HF820 rock drill. Its role includes:

• Reducing friction between moving parts

• Maintaining alignment and support for the drifter shaft

• Withstanding axial and radial loads during operation

• Helping to dissipate heat generated during high-speed drilling

Its design is optimized for heavy-duty conditions where tolerance precision and structural integrity are non-negotiable. With this part in place, operators experience fewer breakdowns and enjoy more efficient maintenance cycles.

Installation Tips

• Always ensure clean and debris-free housing before installation

• Lubricate the bearing with the appropriate grease or oil as specified for HF820 systems

• Use calibrated torque tools to avoid over-tightening adjacent components

• Periodically inspect for wear and replace as part of preventive maintenance

Correct installation of the 550 261 46 BEARING HF820 DRIFTER SANDVIK ensures minimal downtime and optimal drifter performance across your entire fleet.
