Where do I need a belt guard and why?

In order to be compliant with OSHA regulations, a belt guard is needed on any moving belt or drive. Typically where there are two pulleys, both pulleys need to be enclosed the full length from shaft to shaft.

What thickness of metal does Custom Products use for belt guards?

During the design phase we determine the overall size of the guard and the strength needed to support that size. In most cases of guards under 60" in length , we use 16 guage carbon steel, unless otherwise noted or requested. Larger guards will require thicker material to keep strength integrity and are typically 14 to 11 guage.

Does my belt guard have to be fabricated from carbon steel?

No. If a certain metal is not specified we will default to carbon steel, however we carry a full assortment of alloys to accomodate your needs. We stock aluminum, stainless steel and rare metals such as zirconium, Hastelloy-C, Inconel and titanium.

Why do you offer perforated metal for the face of the belt guard?

A perforated front and back panel on the belt guard serves a few purposes. First, it allows visual inspection of the drive belt and guard without having to open it up. Secondly, it provides ventilation. Some guards need to have this ventilation due to heat and/or collection of dust or debris.

Why are holes in the belt guard not allowed to be larger than 1/4" in diameter?

Holes are 1/4" in diameter or less per OSHA regulations. This prevents the possibility of fingers from accidently coming in contact with any moving belts or pulleys.

Why do you add a 2" clearance around both pulleys while designing the overall size of the belt guard?

OSHA requires a 2" void around the entire pulley for any collection of debris, more compact guards have the ability to catch fire.

How do I get dimensions in order to specify my belt guard?

We have made this task very simple for you. We have created a "Design Your Own Belt Guard" form that is either online or in pdf format for download. This form will ask you to measure the diameter and thickness of each of your pulleys additionally we need to know the distance from the center of pulley A to the center of pulley B. The form will also give you options for the design such as the style of guard, the kind of metal, paint. We will take care of the rest from there, and give you a quote quickly.

Do you have any off-the-shelf belt guards that we can buy?

No. Every belt guard that we make is created specifically for the machine it will go on. Each guard is made to order per your specification.
