Standard guards cover common shaft, coupling, and bearing configurations using a general-purpose flanged design, making them a practical default choice when equipment doesn’t call for a specialized tapered or rectangular guard shape. A standard flanged guard mounts to the surrounding structure or bearing housing using a bolt pattern around its flange, offering straightforward installation across a wide range of equipment types. Because standard guards are manufactured in common stock sizes, they’re often readily available for routine guard replacement without a long lead time. 3BG Supply Co. stocks standard guards in steel, aluminum, and polycarbonate options, alongside our rectangular guards and tapered guards lines within our broader machine guards selection.

FAQs
What is a standard guard used for?
A standard guard covers common shaft, coupling, and bearing configurations using a general-purpose flanged design, serving as a default guarding option when equipment doesn't require a specialized shape like a taper or rectangular guard. It mounts to the surrounding structure or housing using a bolt pattern around its flange.
How do I know if I need a standard guard versus a tapered guard?
A standard guard suits components with a consistent, non-tapered profile, while a tapered guard is designed specifically for components that narrow along their length, such as certain shaft or coupling transitions. Checking the profile of the component you're guarding will indicate which shape is the right fit.
What materials are standard guards available in?
Standard guards are commonly available in steel, aluminum, and polycarbonate, offering a range of impact resistance, weight, and visibility depending on the application. Polycarbonate versions allow visual inspection of the guarded component without disassembly.
Are standard guards available in stock sizes?
Yes — standard guards are typically manufactured in common stock sizes to cover routine guarding and replacement needs, which usually means shorter lead times than a fully custom guard. Custom sizing is generally available as well when stock dimensions don't match your equipment.
How is a standard guard mounted to equipment?
A standard guard mounts using a bolt pattern positioned around its flange, attaching either to the bearing housing or the adjacent equipment structure depending on the design. Installation typically doesn't require special tools beyond standard fasteners.
