ChangTa Input & Output Shaft Seal Set for Rotary Cutter Gearbox – 40HP & 50HP, 2 Pack

Overview

Upgrade your rotary cutter gearbox with the ChangTa Input and Output Shaft Seal Set. Designed for 40HP and 50HP gearboxes, this 2-pack focuses on reliable oil seal replacement to help protect the gearbox grease and minimize the intrusion of dirt and debris. The result is smoother operation and a more consistent lubrication environment, without promising guaranteed performance, as actual results depend on your specific setup.

These seals deliver a balanced combination of precision and practicality. They are engineered to fit common shaft configurations found in popular models, offering a practical option when OEM parts are discontinued or priced higher than alternatives.

Compatibility and Specifications

Compatibility is framed around typical 40HP rotary cutter gearboxes, including brands and models used in agricultural tasks. The seals are sized for gearboxes with a 1-3/8" input shaft (smooth or splined) and a 1.57" output shaft with 12 splines. This enables a wide range of replacements while preserving the grease life and protecting internal components from contaminants.
