Shims – more than just a strip of metal

SHIM – A washer or thin strip of metal used to align parts, make them fit or reduce wear.

These, sometimes extremely slender, strips of metal are very crucial in industrial operations. From getting a pump to line up perfectly or to make a surface level, a shim must be exact.

 

don’t let your shims get this bad!

 

Shims come in a variety of materials, but most commonly from metals such as carbon steel, brass and stainless steel. And they also vary greatly in their thickness from up to 1/4” thick and down to .001 thick (imagine an industrial foil).

 

.003 thick shims – for precise applications

 

And the tolerances they must hold are key to their functionality. They cannot deviate across the surface, their dimensions must be held.

 

 

Often industrial shims come in sets of varying thicknesses. They can be added individually to get the final adjustments perfect.

They also come in many different shapes, often having to be custom designed to fit around existing bolt holes and other features. We like to add the small hand holds (show below) to make installation and adjustment easier.

At Riggs Machine and Fabricating we understand Industrial Shims and their importance in setup, maintenance and repairs. We understand the tolerances and design elements that separate a shim from a strip of metal. Yes, there is a difference. If the shop you are working with now doesn’t agree with that, then you are working with the wrong place. Time to call Riggs Machine.

Is Your Scaffold System OSHA Compliant?

Ladder on Scaffold by George Hoden

Do you use long term scaffolding in place of permanent platforms? Are they stable, secure and up to the new OSHA regulations? Are you still renting your scaffolding and paying for it month after month?

FALL PROTECTION & SCAFFOLDING VIOLATIONS

remain among OSHA’s most frequently cited standard violations.*

 

 

OSHA violations are now subject to higher penalties,

this signals a 78% increase in penalty amounts.*

 

Convert your temporary, unstable scaffolding to a sturdy, permanent structure. No more rentals, no more repairs, no more guard rails that are dangerously low and above all, avoid the fear of those outrageous OSHA fines.

A Riggs Machine representative will review your current needs and outline the best options for your facility. We even offer 3D renders of the unit before construction begins so you can visualize the actual unit design.

Roll Turning

The Heart of the Steel Plant – the Rolls!
Flat rolls, grooved rolls or custom cuts, if the rolls aren’t to spec, the final product won’t be either.
Not only do bad rolls produce bad products, they can be dangerous to your facility.

A Pioneer in CNC Roll Turning
Riggs was one of the first shops to use CNC lathes to dress passes in rolls.
This is far superior to the old plunge cutting method. CNC pass cutting gives exacting tolerances and an exceptional finish.

Better Components …
A lot has changed since many of these units went into service.
Many components are just made better than the OEMs. Better springs, rings and gaskets mean more reliable equipment.
