Pulley Alignment - Schaeffler LASER TRUMMY2

PART NUMBER: TB-BA780703

Correct belt tension is critical to ensuring maximum service life of both the belt and its drive components. The Schaeffler LASER-TRUMMY2 is a durable, optical-electronic handheld measuring device designed for precise measurement of belt tension. It includes both a wireless measuring probe for direct connection and a cabled probe for hard-to-reach areas, making it adaptable to a range of applications.

Measurements are taken when the machine is stationary, displaying two key values: frequency (Hz) and torsional force (N). These readings can be compared with target values specified by belt drive manufacturers to ensure optimal performance. The LASER-TRUMMY2 helps maintain proper alignment, prevent bearing damage, and reduce wear and noise — all contributing to extended system longevity and energy efficiency.

Advantages:

• Accurate measurement and adjustment of belt tension
• Suitable for difficult-to-access locations
• Simple, one-handed operation
• Reduces bearing wear and running noise
• Extends service life of belts and drive components
• Energy-efficient and user-friendly design
