Tb Wood's E134 Type E Quick-detachable Sprocket Bushing

Product Description

The TB WOOD'S E134 is a Type E quick-detachable (QD) sprocket bushing designed for secure shaft-to-sprocket connections in industrial power transmission applications. Featuring a 1.75-inch bore with a 3/8-inch keyway width and 3/16-inch keyway depth, this iron bushing handles up to 20,000 inch-pounds of torque. Its quick-detachable design allows for straightforward installation and removal without specialized tooling, reducing downtime during maintenance cycles. The E134 is suited for applications where reliable torque transfer and repeatable mounting are required across a range of sprocket outside diameters from 3.834 to 6 inches.

This bushing is intended for use in industrial and commercial power transmission systems, including conveyor drives, pump drives, and general machinery where chain-driven sprockets are employed. The QD bushing system is a widely adopted standard in manufacturing facilities, processing plants, and mechanical rooms. Maintenance technicians and mechanical contractors working on roller chain drive assemblies will encounter this bushing as a standard component in drive system builds and retrofits.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with power transmission drive systems. De-energize and lock out the drive system fully before removing or installing any bushing or sprocket assembly in accordance with applicable OSHA lockout/tagout procedures. Ensure the shaft, bore, and keyway are clean and free of burrs before seating the bushing. Consult the drive system design specifications to confirm bore size, keyway dimensions, and torque requirements before installation.
