Rope Sheave or Wire Rope Sheave

What is the difference between Rope Sheaves and Wire Rope Sheaves?

Rope Sheaves are for fibrous rope. They have a full radius or groove.

Wire Rope Sheaves are “v” grooved, cradling the wire rope to prevent it from coming out of the groove. 

Our wire rope sheaves are up to 3/8” Maximum diameter. 

Our Rope sheaves go up to 1” rope. Wire rope is not as flexible as regular rope, so it is not advisable to use wire rope in a regular rope sheave, because it will force the wire rope to bend around too tight a radius. This can cause it to bunch up, and unwind.

Ball Bearing Sheaves are used on a continuous run situation, constant revolutions.

Bronze Bushings are more durable and can withstand a heavier load, but are intended for a slower use and not rotating continuously. Another bearing is not necessary for use along with the bronze bushing. We use “660 bronze” which is a leaded tin bronze. It allows rotation with very low friction.
