Shaft covers guard exposed lengths of rotating shaft between bearings, couplings, or other drive components, protecting personnel from contact and keeping debris away from the shaft surface. Unlike a bearing cover, which shields just the bearing end, a shaft cover typically spans a longer run of exposed shaft, making it a common guarding solution on conveyors, pumps, and other equipment with an accessible rotating shaft section. Because a bearing shaft cover often works alongside a bearing cover at each end of the shaft run, MRO teams frequently order the two together to fully enclose an exposed drive shaft. 3BG Supply Co. stocks shaft covers in a range of lengths and diameters, alongside our bearing covers and seals lines, since a well-sealed and well-guarded shaft reduces both contact hazards and contamination-related wear.

FAQs
What is a shaft cover used for?
A shaft cover guards an exposed length of rotating shaft between bearings, couplings, or other drive components, protecting personnel from accidental contact and keeping debris off the shaft surface. It's commonly used on conveyors, pumps, and other equipment with an accessible rotating shaft run.
How is a shaft cover different from a bearing cover?
A bearing cover shields just the exposed end of a bearing housing, while a shaft cover spans a longer section of exposed rotating shaft between components. The two are often used together to fully guard a drive shaft from end to end.
What materials are shaft covers typically made from?
Shaft covers are commonly made from steel, aluminum, or polycarbonate, similar to other machine guards, with the material choice depending on required impact resistance, weight, and whether visual inspection of the shaft is needed. Polycarbonate options let maintenance teams check shaft condition without removing the guard.
How do I determine the right length shaft cover for my equipment?
Measure the full exposed length of rotating shaft you need to guard, from the edge of one bearing or coupling to the next, and select a shaft cover that spans that distance with some margin for mounting hardware. Custom lengths are typically available if standard sizes don't match your shaft run.
Do shaft covers help protect against contamination as well as contact hazards?
Yes — in addition to preventing accidental contact with the rotating shaft, a shaft cover helps keep dust, debris, and moisture off the shaft surface, which can reduce wear on seals and couplings along that section. Pairing a shaft cover with proper seals at each bearing further reduces contamination-related failures.
