Half Coupling B Type Pilot Bore (HRCP090)

Premium Elastomeric Shaft Coupling Component

The HRCP090 Half Coupling B Type is an essential component of the HRC elastomeric shaft coupling series. This pilot bore component features a pocket configuration (“B Type”) designed to house the interlocking teeth of an elastomeric element or a corresponding “A Type” half coupling. Together, they create a flexible connection that handles high shock loads, dampens motor vibration, and corrects parallel, angular, and axial shaft misalignments.

Manufactured from premium **Cast Iron EN-GJL-250 (UNI EN 561)**, this half coupling offers outstanding wear resistance, dimensional stability, and durable torque handling capacity under rugged operating conditions. Supplied with a machinable pilot bore, it can be easily bored out to your custom shaft requirements.

Key Benefits & Features

High-Grade Construction: Cast from heavy-duty EN-GJL-250 gray cast iron for maximum tensile strength, vibration absorption, and structural endurance.
Flexible Shaft Alignment: Protects industrial electric motors and gearboxes by securely accommodating operational drivetrain shock and misalignments.
Machinable Pilot Bore: Delivered with a raw pilot bore stock setup, providing full customization flexibility to accommodate standard or specialized machinery shaft sizes.
