LASE-A-LIGN Shaft Alignment Systems

Misalignment is the most common cause of machinery malfunction. Misaligned equipment causes premature bearing, seal, coupling and shaft failures which leads to an increase in maintenance costs. John Crane’s LASE-A-LIGN™ Shaft Alignment Systems simplify the process of shaft alignment for rotating equipment to ensure optimal efficiency.


Basic Shaft Alignment System

Precision alignment of rotating machinery is now achievable on a budget and has never been simpler than with the LASE-A-LIGN™ Shaft Alignment System. LASE-A-LIGN Shaft Alignment System is a high-precision, user-friendly alignment system, incorporating functions to eliminate human error and optimize productivity. With its straightforward and intuitive operation, LASE-A-LIGN Shaft Alignment System is a dynamic precision laser alignment measurement instrument that won't overstretch your budget.

LASE-A-LIGN Shaft Alignment System allows reports to be saved and exported in .pdf format to a memory stick. Ideal for maintenance departments in industrial organizations, this highly developed and user-friendly system measures and aligns machinery used in the power, chemical, water treatment, production and processing industries.
