Lovejoy Coupler, L100 X 1"

The L1001.00 Lovejoy Coupler Hub is a durable L100 jaw coupling hub designed for reliable power transmission with vibration damping and easy serviceability. Made from sintered iron and paired with an SOX (NBR/Buna-N) rubber spider, it delivers oil-resistant flexibility while helping reduce shock loads—plus a fail-safe jaw design that can continue operating even if the elastomer fails. This hub features a 1" bore with a 1/4" x 1/8" keyway, making it a solid choice for common shaft sizes in industrial and agricultural drive systems.
