54J227 – Flexible Coupling Insert, Rex E10, Compatible With Milnor

The 54J227 flexible coupling insert is designed to absorb shock, dampen vibration, and compensate for minor shaft misalignment in Milnor commercial laundry equipment. This coupling corresponds to the Rex E10 size, commonly used in drive systems where smooth torque transmission and equipment protection are critical.

Manufactured from durable elastomeric material, the coupling insert helps reduce wear on motors, gearboxes, and bearings by minimizing torsional shock during start-up and load changes. Its split-insert style allows for faster replacement without disturbing hubs or requiring extensive disassembly, making it ideal for routine maintenance and downtime reduction.

This component is a compatible replacement for Milnor applications, referenced by part number 54J227, and is well-suited for washers, extractors, and auxiliary drive assemblies.

Maintenance Tip:
Inspect coupling inserts during scheduled PMs for cracking, hardening, or deformation. Replacing worn inserts early helps prevent hub damage and drivetrain misalignment. Trusted by laundry engineers for protecting critical drive components.

Installation Notes

• Quantity: 1 set (includes both coupling insert halves shown)

• Fastener Guidance: Use Loctite® 222 (low-strength threadlocker) on mounting bolts

• Important: Do not reuse or install locking tabs with this coupling insert
