When it comes to durability and a great price, Maurey Manufacturing’s comprehensive line of
split steel sheaves offers end users the best of both worlds. A strong precision weld provides
a superior bond between the sheave and its machined hub. All hubs are also precision bored
and keyed from solid steel, thus offering excellent field performance for many years. These
sheaves meet the high market demand for a product that is very economical; stronger than
our welded two-piece stamped steel sheaves, yet does not require the rugged cast iron
construction of our standard sheave line. Contact us now at 1-800-284-2161 to discover how
these sheaves can save your company money.

With a spoke design that minimizes air resistance these Maurey sheaves assure utmost efficiency on air conditioning
and similar installations. A special annealing process makes the spokes and the entire pulley extra strong. Balanced
and true running, they assure quiet, efficient and low cost power transmission. Pulleys have rust-resistant finish.
