Martin 60BS28 1 3/8

Description

Martin Sprocket & Gear type BS sprockets, also known as a bored-to-size sprockets, include two set screws and a keyway. These finished bore sprockets have been adapted for installation on a shaft without additional components.

Finished bore sprockets are generally used in low power applications and have less clamping power than bushed bore sprockets. And, unlike plain bore sprockets, they cannot be customized or machined to accommodate shaft variations or to suit special application or size requirements.

Martin BS sprockets are made from high carbon steel for high strength and durability. They have a hub extension on one side to provide stability and allow for the use of a full-depth keyway and two standard set screws to attach the sprocket onto a shaft.
