L-708 / L-708LD Stern-Tube Bore Alignment System

Product catalog summary

Introduction
The L-708/L-708LD Stern-Tube Bore Alignment System by Hamar Laser is designed to provide a faster and more accurate method for aligning bores, utilizing over 47 years of laser alignment innovation. It is suitable for high precision applications across various industries.

Specifications
The system offers a resolution of .00002" (0.0005 mm) and can align bores to .0012" (0.03 mm) with repeatability to .0002" (0.005 mm). For higher accuracy needs, the laser can be mounted externally to achieve accuracies down to .0002" (0.005 mm).

Key Features

Self-Centering Target Adapters: These adapters reduce alignment time by 50% and maintain accuracy despite diameter changes.
Wide Range of Bore IDs: Capable of measuring bore diameters from 0.25” to 40” (6.6-1,000 mm).
Reference Target Monitoring: Essential for long-distance applications to monitor and adjust for laser drift.
Minimal Training Required: The system is user-friendly, requiring only 1-2 days of training.

Advantages of Laser Systems

Speed: Alignments are up to 3x faster than traditional methods.
Accuracy: Provides more accurate and repeatable measurements, reducing operator variability.
Efficiency: Requires less manpower, reducing labor costs and increasing profits.

System Components

Self-Centering Laser/Adapters: A-514 adapters allow for quick and accurate positioning on the bore centerline.
Long Range Capability: The L-708 can be used up to 100 feet (31 m) and the L-708LD up to 200 feet (61 m).
Wireless Data Transmission: Supports wireless data transmission up to 400 feet (120 m) using Zigbee technology.

Software and Accessories

Bore9 Software: A Windows-based software that simplifies the alignment process with a 5-step guide.
Optional Accessories: Includes various adapters and targets for specialized applications.

Specifications for Adapters

A-514B Target Adapter: For medium bore diameters from 6.50" (165 mm) to 17.5" (445 mm).
A-514C Target Adapter: For large bore diameters from 17" (431.8 mm) to 40" (1 m).
A-514G: Sets A-514 Adapters legs to correct bore diameter with precision.

Procedures
Use A-514GS for A-514A & B Adapters and A-514GL for A-514A, B & C Adapters to ensure proper setup and measurement accuracy.

L-708 / L-708LD Stern-Tube Bore Alignment System-2

From the beginning, mechanical and optical methods of alignment in stern tube applications have been the tried and true methods for aligning stern tube bearings to drive-shaft gearbox rotation axes. However, there is a MUCH better way: lasers. It is an established fact that lasers offer faster and much more accurate alignments than optical or mechanical methods, and in most cases, are easier to learn and to use! Here are just a few of the many advantages of lasers over traditional methods:: L-708 & A-514 Bore Adapter in Aft Strut Bore Results 3x Faster Than Optical Bore Scopes or Tight Wire Setup...
