Baby Lock BL20A Parts & Accessories
We hold 5 items whose specification names the BL20A: extension tables, inserts & frames, tension, springs & small parts, needle plates, feed dogs & needle parts, bobbins & hooks. Parts made by Baby Lock are listed under the Baby Lock name; third-party parts made to fit this model are labeled compatible, never as the brand's own; Sew Steady tables and inserts are cut to this model's bed. Nothing on this page is assumed from a sibling model — if a part is here, the BL20A is named on it.

Most-replaced parts on the Baby Lock BL20A
Needle Plate Babylock BL20A Zig Zag (508612000, $19.90): a needle strike leaves a burr around the hole that snags thread and fabric; on a serger the stitch finger wears and the edge stops forming cleanly.
Thread Take Up Lever Unit Babylock BL20A Anna (508634008, $39.90): a damaged take-up lever drops the top thread and the machine jams at the first stitch.
Bobbin Winder Babylock BL20A Anna (508620001, $17.90): a winder tyre that has hardened spins without winding; the unit replaces as one.
SEW STEADY TABLE Babylock BL20A ANNA 18x24 (DW-BL149, $149): an extension table is cut to this machine's bed and free-arm position; sibling models are not automatically the same.
Finding your model number
The model number is on the machine itself, not on the carry case or the manual — look for a plate or sticker on the front of the base, the right-hand side, the back near the power socket, or underneath. On a Baby Lock it is printed as BL20A and the letters and suffix are part of it; a sibling model with a different suffix can take different parts.

Frequently asked questions
Which parts do you stock for the Baby Lock BL20A?
5 items whose specification names the BL20A: 1 extension tables, inserts & frames; 1 tension, springs & small parts; 2 needle plates, feed dogs & needle parts; 1 bobbins & hooks. Each one is listed above with its price and whether it is the manufacturer's part, a compatible part, or an accessory cut for this model.
Are the compatible parts for the BL20A as good as the original?
A compatible part is made by a third-party manufacturer to the dimensions of the Baby Lock part and costs less. For bobbin cases, plates, knives and feet that is usually a sensible buy; for a hook or anything with moving parts on a newer machine the manufacturer's part is the safer choice where we have it. We never describe a compatible part as the brand's own.
Will a Sew Steady table for the BL20A fit a different Baby Lock model?
Only if that model is named on the table's page. Tables are cut to the bed shape and free-arm position; the names listed on each table are the models the distributor specifies. Email us the other model number before ordering.
Do these parts also fit the Baby Lock MC6600?
1 of the 5 items on this page name the MC6600 as well, because the two models share those parts. The rest do not — check the fits-these-machines list on each part, and see the related machines below.
My BL20A needs a part that is not listed. Can you get it?
Email the part name and your model number to support@ultimatesewingandvac.com. If the distributor's catalog carries it we will quote it; if the fitment is uncertain we will say so rather than guess.
Do you ship the same day?
No. Orders are released to the warehouse the next business day and tracking is emailed when the parcel ships. We do not hold stock ourselves, so if an item is unavailable after you order we email you first.
