Premium Replacement Magnetic Bobbin Case 52237M is an advanced upgrade for your Brother DB2-B737 industrial sewing machine. Designed to solve the common problem of "bobbin spin," this case features an integrated magnet that provides constant, light tension on the bobbin, ensuring a flawless sewing experience even at the highest speeds.Why Choose a Magnetic Bobbin Case?Standard bobbin cases rely purely on mechanical springs, which can wear out or lose tension. The 52237M magnetic version offers a modern solution for professional sewers:No-Back-Lash Magnetic Control: The built-in magnet prevents the bobbin from continuing to spin when the machine stops suddenly. This eliminates "bird-nesting" and tangled thread at the start of your next seam.Consistent Tension: By holding the bobbin flat and centered, the magnet ensures a uniform thread pull, resulting in perfectly balanced stitches on both the top and bottom of your fabric.Ideal for High-Speed Trimming: Specifically compatible with the Brother DB2-B737 automatic thread trimmer, keeping the bobbin thread stable during the cutting cycle.Durable Construction: Made from high-quality, hardened steel with a polished finish to resist scratches and provide years of reliable service in an industrial environment.Product SpecificationsFeatureDetailsPart Number52237MCompatible MachineBrother DB2-B737Tension StyleMagnetic Anti-SpinMaterialHardened Industrial SteelExpert Tip: Magnetic bobbin cases are a favorite among professionals working with nylon or bonded polyester threads, as these threads tend to "spring" off the bobbin. This Premium Replacement keeps those slippery threads under total control.
