51546455 Ingersoll Rand OEM Drive Coupler | Genuine Heavy-Duty Industrial Coupling

51546455 Ingersoll Rand OEM Coupler – Product Overview

The 51546455 Ingersoll Rand OEM Drive Coupler is a precision-manufactured, high-strength elastomeric coupling designed for demanding industrial and compressor applications. Built to exact Ingersoll Rand standards, this genuine OEM part provides dependable, backlash-free torque transmission while isolating the motor and air-end from harmful vibration and misalignment.

Whether used in portable or stationary rotary screw compressors, this coupling plays a vital role in maintaining smooth, efficient, and reliable machine operation. Its balanced, vibration-absorbing design minimizes component fatigue and helps extend service life across the entire drive system.

Key Features and Benefits

• Authentic OEM Component – Manufactured under Ingersoll Rand’s strict engineering and quality controls for a guaranteed fit and long-term durability.

• High-Performance Elastomeric Element – Flexible yet strong, the element absorbs torsional vibration and dampens shock loads.

• Backlash-Free Power Transfer – Provides smooth torque delivery under variable load and speed conditions.

• Protection Against Overload – Acts as a sacrificial element that fails safely under extreme stress, preventing costly motor or air-end damage.

• Minimal Maintenance – Element replacement requires minimal tools and downtime, keeping systems operational.

• OEM Compatibility – Designed specifically for Ingersoll Rand rotary compressors and interchangeable with select factory-installed couplers.

Technical Function and Design

This coupling connects the motor shaft to the air-end or driven component, transmitting rotational energy while compensating for slight parallel, angular, and axial misalignments. The elastomer element at the core of the 51546455 coupling isolates vibration and reduces torsional spikes, which are major causes of premature bearing and seal wear.

By maintaining proper alignment and torque distribution, the coupler enhances operational efficiency, reduces noise, and helps preserve the precision balance of the compressor’s internal components.

Applications and Compatibility

The 51546455 Coupler is used primarily in Ingersoll Rand rotary screw compressor drive assemblies and compatible heavy-duty equipment. It’s suitable for use in both portable and stationary units that require consistent, shock-free power transfer between the motor and air-end.

Typical applications include:

• Construction and mining compressors

• Industrial pneumatic systems

• Drilling and heavy equipment drives

• OEM and aftermarket compressor rebuilds

If you operate or service Ingersoll Rand machinery, this coupling is the exact replacement specified for reliable, factory-grade performance.
