Jeamar Sheaves
About Jeamar Sheaves
Jeamar sheaves are heavy-duty sheaves designed for the most demanding applications. Precision machined from solid steel or stainless steel blanks for the utmost consistency and quality. Includes sealed bearings in the bore for smooth operation in harsh conditions. Stainless sheaves are uncoated while the steel versions are powder coated. Jeamar sheaves have been trusted for 50 years to deliver reliable performance.

Advantages of Jeamar Sheaves
High Strength to Weight Design
Alloy steel sheave with machined web profile reduces unnecessary weight and provides highest strength to weight ratio.
High Sheave-to-Rope Ratio
Minimum 15:1 sheave pitch diameter to rope diameter ratio to reduce rope bending stress and increase rope life.
High Working Load
Sheaves are rated for the full working load limit of the allowable wire rope size at a 180 degree wrap angle.
High Efficiency Bearing
Sheaves utilize either sealed ball bearings or cylindrical roller bearings for reduced friction, smooth motion, and lifetime lubrication.
