Sheave Construction

DODGE stock sheaves are manufactured from high quality gray iron. They are given a corrosion-resistant finish before packaging and shipping. Sheave construction follows the general format: smaller sheaves are of the block construction, intermediate sizes of the web type, and large sheaves of the arm- type construction.

Sheave Balance

Static balance of stock sheaves is suitable for most applications up to a rim speed of 6500 FPM. Dynamic (two-plane) bal ance is available at extra charge for applications that are more sensitive to vibration. Dynamic balance is recom mended for operation above 6500 FPM.

WARNING

Stock sheaves are manufactured from gray iron, which is suitable for operation up to 6500 feet per minute rim speed (e.g. 14, max. dia. on a 1750 RPM motor). Operation above this rim speed may cause sheave failure resulting in personnel and/or equipment damage. Refer to the Made-To-Order sheave section for constructions that are suitable for operation at higher rim speeds.
