Knitting Machine Sponge Bar

Highest quality. One Price. Sponge only available for rebuilding.
Knitting Machine Sponge Bar. aka needle retainer bar. Ours are highest quality sponge bars. All sizes are one price and have metal backing attached to the sponge bar except for plastic bed models which do not require metal backing and are less expensive. Sponge bars are also called needle retainer or compression bar. Sponge bars supply back up pressure for needles yet it holds them in place to allow needle movement. Over several years the foam rubber will lose its elasticity, the foam rubber decomposes and collapses. Sponge bars should be examined and replaced whenever the foam rubber loses 1/2 its original height, typically3-5 years. If your machine starts dropping a stitch or the carriage jams, you may need a new sponge bar. When ordering, please be sure to include your machine name & model number - it does cut down on errors. If you are not sure of your selection, please call or E-mail us before you order. Needle Retainer Bar aka sponge bars for Studio, Brother, KintKing, Empisal, Toyota have the Metal Back.  Studio LK150, LK100, LK140, and Brother models KX350 and KX400 Sponge Bars are plastic bed machines and do not require metal backs.
  • Toyota knitting machines use a special design sponge bar for machines that use extension rails. If you use extension rails with your Toyota machine, you will need to rebuild your old sponge bar or modify one of ours to work with your machine. No sponge bars are commercially available to work with Toyota extension rails.

  • Some knitting machine sponge bars are no longer made - those include Brother KH-120, Bulky 8 and Studio/Singer SK8 and SR-20 ribber bar. Some ribbers were originally sold with a solid plastic bar - these are no longer manufactured. A regular sponge bar works fine in its place and will be substituted for the original plastic bar. This type of sponge bar is required anyway when knitting lace or using thin yarn such as 2 ply (2/28 or 2/30) as the plastic bar does not work well for knitting lace or thread yarn.
