S-600 Sheave Alignment System

Simplifies sheave alignment and maximizes accuracy with groove-to-groove operation
Simplifies sheave alignment and maximizes accuracy with groove-to-groove operation

Versatile and accurate

The groove-referenced laser and target use selectable precision ball blocks to allow genuine groove-to-groove alignment. A standard set of ½ inch precision ball blocks is provided with the system to accommodate the widest variety of sheave grooves. For special needs, a complete range of sizes are available. Aligns both classic and narrow V-belt sheaves (standard and deep groove). Readout provides groove readings in inches or millimeters and pitch and yaw readings in inches per foot or millimeters per meter.

Easy to use and reliable.

Just clamp on the laser and target and begin aligning…no complicated setup procedures or difficult calculations to perform. A single readout provides readings for pitch (up and down) and yaw (left and right) angles as well as groove readings. The readout sequence (PITCH/YAW/GROOVE) defines the alignment operation. Battery-operated for portability.

Why is accurate sheave alignment important?

Sheave (pulley) misalignment occurs when the grooves of the driven and driving sheaves are not parallel or in line. Excessive groove and belt wear causes increased vibration over time, reducing the life of bearings and other machine components. Vibration of the driven spindle also affects the quality of the work produced.

Common "eyeball" methods of sheave alignment using a straight-edge don't provide the necessary accuracy because these methods use the faces of the sheaves (which are rarely parallel to the grooves) as a reference.

Why is the S-600 Sheave Alignment System from Hamar Laser Instruments different?

Because it works from the grooves and aligns groove-to-groove, not sheave face-to sheave face. The system restores correct pitch, yaw and groove alignment, allowing full driving torque from the belts. Proper alignment, together with correct belt tension, reduce driven spindle vibration to a minimum. The system is also cost-efficient, easy to use, and versatile, with many options available to accommodate a wide selection of sheave sizes and types.
