Founded in 1990, China Famen Bearing Co., Ltd. is specialized sheave manufacturer and sheaves distributor of all types of custom and cheap bearings. We obtained ISO9002, ISO14001, and QS9000 certificates in 1995 and 1996, 1999 respectively. Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1,500 kilograms per hour. The Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units.

All-steel rope hoist has steel blocks, steel sheaves and wire-formed steel swivel hooks top and bottom. Locks the load at any height, with self-locking block and tackle for light-duty lifting. Includes 50-ft. rope. Limited lifetime warranty. U.S.A. Time is Money. You don't have to wait months or weeks to get a new wire rope sheave. We stock so many sheaves that we usually have exactly what you need in stock. If we don’t have the sheave you’re looking for, we can usually find one to fit your needs. Give us a call today with your sheave needs. Our wire rope sheaves sizes range in size from 1 1/4" to 60" in diameter. Sheaves are available in plain bore, bronze bushed, roller bearing, iron, cast steel and cast nylon. We can also rework stock sheaves to fit virtually any application that is required.

Standard Keyway W x D: 3/16" x 3/32"
Just like our single V-groove pulleys, these solid cast iron double V-groove pulleys are machined and statically balanced to provide the smoothest power transmission possible. For A belts. Pitch diameter: 4", Bore: 3/4", Standard Keyway W x D: 3/16" x 3/32", Produced as a specialty product to meet a demand, BailSco's cast aluminum v-belt sheaves have captured the imagination of engineers who are faced with unusual conditions such as aggressive atmospheres, weight requirements, and installation problems. Now in the field for over ten years, BailSco's sheaves can be produced from small diameter driver sheaves up to a driven sheave of 38" in pitch diameter. Since BailSco is an intergrated facility, the sheave design, mold manufacturing, casting, machining, heat treating, and balancing are all done "in-house".
In the ever changing worlds of engineering and manufacturing, BailSco continues to lead the field in innovative ideas relative to producing high quality sheaves. This includes the availability of professional experts in the field of vibration, natural frequency, and casting design. Using Finite Element Analysis techniques, the sheave design has been studied to reduce weight and improve the design prior to producing the patterns.
