Easy to remove

 

 

 
 

1

Metaligner Removal - Step 1

 

 

An internally threaded pull nut is screwed onto the pin
 
 

2

Metaligner Removal - Step 2

 

 

As the pull nut seats on the sleeve, the pin is released
 
 

3

Metaligner Removal - Step 3

    With the pin removed, the sleeve puller is inserted into the recess in the base of the sleeve

  How Metaligner ® works.  
  If you have an application requiring precision alignment of parts at assembly, reassembly or for field service, the Whistler Metaligner can help you do it faster and easier with outstanding accuracy.

The
Metaligner ® is a reusable, expanding dowel pin, designed to allow precise alignment of two or more members that would normally be held in place by conventional dowels. Unlike conventional dowels, the Metaligner ® can be easily inserted and removed where the sections to be doweled have a blind hole. It never has to be drilled out.

Machine and tool sections can be removed and replaced repeatedly with accurate alignment every time. Plus,
Metaligner ® is reusable and can properly align and dowel holes as much as .001" (.025mm) oversize.
 
     
  Metaligner Family The advantages of Metaligner ® are being proven by builders of mechanical equipment around the world in the construction of machine tools, pumps, disc drives and precise assemblies of all kinds.  
     
 

Metaligner ® benefits.

 
  Requires less precision in a hole size since expansion allows use over approximately a .001" (.025mm) range.

Can be used in blind holes and does not require a through-drilled knockout hole for removal.

Naturally vents air so that "flatting" is not required.

Does not damage a hole through use, so it can be removed and reused in the same hole without re-machining.

Faster to use in an assembly and can be removed very easily and quickly for disassembly.

Can provide repositioning of mating sections with accuracies better than .0001" (.0025mm) for in-field service or repair.
