Tension Complete for Brother CP100X

If your Brother needs a new tension unit, this is the part listed for the Brother CP100X.

This list comes from the distributor's listing for this part. If your model is not named, do not assume it fits — check the part you are removing against the specification below, or ask us with your model number before ordering.

What this part does

The upper tension unit is the pair of discs, spring and dial that put drag on the needle thread. Lint between the discs, a tired spring or a grooved disc all show up as uneven stitching that re-threading does not fix.

Specifications

How to tell if this is the right one

Match by the model list. Tension units differ in mounting, dial type and whether they include the check spring.

Signs you need this part

Loops on the underside, thread breaking, tension that changes when nothing was adjusted, or a dial that turns without changing the stitch.

Fitting it

Most household units are held by one screw behind the dial and pull straight out. Thread through the discs with the presser foot UP so the discs are open.

Questions about this part

Does this tension unit fit the Brother CP100X?

Yes. The Brother CP100X is on the distributor's fitment list for this part. If your model is not listed on this page, send us the model number and we will check before you order.

Is this the original Brother part?

It is listed by our distributor under the Brother brand name. We describe every part exactly as the distributor lists it and make no claim beyond that.

Should I try cleaning before replacing?

Yes. Run a folded piece of thin fabric between the discs with the foot up. If the stitch does not improve with clean discs, a new needle and correct threading, replace the unit.
