Genuine Makita compression spring (part no. JM21000056) — replacement spring with a free length of 45 mm designed for the spring‑plate/adjustment assembly on the Makita LB1200F 305 mm band saw. This original Makita spring restores correct preload and return action where the factory spring has sagged or broken; it’s sold as a single coil so you can replace only the worn item and get the saw’s tension mechanism working like new. If you’re matching parts diagrams, JM21000056 is listed specifically for the LB1200F in Makita’s parts breakdowns — an exact-fit part from Makita for that model. Makita parts such as this are usually swapped during routine repairs to re-establish reliable blade tension and smooth adjustment.
