A 3 bolt flange bearing cover is designed to bolt directly onto bearing housings that use a three-hole mounting pattern, shielding the exposed bearing face from dust, debris, and incidental contact. The lightweight construction used in this line makes it a practical fit for equipment operating in less abrasive environments, where full heavyweight protection isn’t necessary but guarding is still required for safety or contamination control. Because the cover reuses the bearing’s existing three-bolt pattern, installation typically doesn’t require any additional drilling or fabrication — the cover simply bolts on in place of, or alongside, the bearing’s factory hardware. 3BG Supply Co. stocks 3 bolt flange bearing cover lightweight models in multiple bore and bolt circle sizes, alongside our 4 bolt flange bearing cover heavyweight line and full bearing covers selection for other bolt patterns and duty ratings.

FAQs
What is a 3 bolt flange bearing cover used for?
A 3 bolt flange bearing cover protects the exposed end of a bearing housing that uses a three-hole mounting pattern, keeping dust, debris, and incidental contact away from the bearing while satisfying machine guarding requirements. It bolts directly onto the housing using the same three-hole pattern as the bearing itself.
How do I measure for the right 3 bolt flange bearing cover size?
Measure the bolt circle diameter (the distance between the centers of the three mounting holes) and the overall bearing housing diameter, then match those dimensions to the cover's published sizing. Getting the bolt circle measurement right is the most important step, since it determines whether the cover's holes will align with your housing.
When should I choose the lightweight version instead of a heavyweight cover?
The lightweight 3 bolt flange bearing cover is a good fit for less abrasive, lower-contact-risk environments where full heavyweight protection isn't necessary. If your equipment operates in a harsher environment with more physical impact risk, a heavyweight cover offers additional durability.
Does installing a 3 bolt flange bearing cover require any drilling or modification?
No — the cover is designed to reuse the bearing housing's existing three-bolt mounting pattern, so it typically installs without any additional drilling or fabrication. Simply align the cover's holes with the housing's bolt pattern and secure it with the appropriate hardware.
Can a 3 bolt flange bearing cover be used on any bearing with a 3-hole pattern?
It can be used on any bearing housing with a matching three-hole bolt pattern and compatible bolt circle diameter, but always confirm the exact measurements against the cover's specifications before ordering. Bolt circle sizes vary between manufacturers, so a quick measurement check helps ensure proper fit.
