Brother SA156 Clear Plastic Bobbins, 10-Pack

Brother SA156 is a ten-pack of clear plastic bobbins. Brother’s product page describes a security notch for winding and a nominal depth of 7/16 inch. The PE545 operation manual specifies plastic bobbins of the supplied type, states a height of 11.5 mm, and names SA156 as a Class 15 bobbin.[1][2]

This is a model-specific supply decision, not permission to install any bobbin labeled Class 15. For the PE545, follow the manual’s winding and installation procedure and use its recommended embroidery bobbin thread. The manual specifies 90-weight bobbin thread; this pack is bobbins, not a supply of that thread. Brother’s SA156 compatibility list also names the SE700. Other machines in the catalog are not silently added to that compatibility claim.[1][2]

Keep bobbin identity and condition visible in your storage routine. When troubleshooting, compare the actual bobbin with the approved type before changing tension or buying unrelated parts. A replacement bobbin does not repair a damaged bobbin case or remove lint from the race. Follow the machine’s safety instructions before accessing the needle or bobbin area. This selection is grounded in manufacturer documentation and was not physically fitted or stitch-tested.[2]
