Embroidery Machine Take-Up Crank Linkage with Dual Bearings — Precision Drive Component
The heartbeat of your embroidery machine.
The take-up crank is where rotary motion becomes linear stitch-making motion. It sits at the core of the drive train, translating every revolution of the main shaft into one complete stitch cycle. When this part develops play or its bearings wear out, the symptoms cascade through the entire machine: timing drifts, stitches vary in length, and thread breaks become frequent.
This replacement crank restores the tight, precise motion transfer your machine needs.
Why quality matters here
•Dual precision bearings. Two deep-groove ball bearings are pressed into the casting at the factory, eliminating radial play and ensuring concentric rotation. No field bearing replacement needed — install the crank as-is.
•Cast steel body. One-piece casting provides superior rigidity compared to assembled or welded alternatives. The mass and geometry are matched to the original design for correct dynamic balance at speed.
•Hex-nut secured shaft end. The left-end fixing uses a hex nut and locating pin for positive axial retention — the crank cannot walk along the shaft under reversing loads.
•Oil passage. A small port on the shaft pin allows periodic lubrication of the bearing interface without disassembly.
Where it fits
Designed for the take-up or needle bar drive position in industrial computerized embroidery machines.
Fitment: Confirm the crank arm length, bore sizes, and bearing specifications match your machine before ordering. Provide your machine model and serial number for verification.
