Why This Circlip Matters
Although small, the retaining circlip performs an important safety and reliability function inside the machine. It prevents internal shafts, rollers, pivots, and linkage components from sliding sideways during operation.
Without a properly fitted retaining ring, internal components may shift out of alignment, leading to excessive wear, poor stitch formation, or unexpected machine downtime.
Replacing worn or damaged circlips during servicing helps extend the life of your portable bag closer and maintains dependable stitching performance.

Frequently Asked Questions
What does the A012 circlip do?
The A012 circlip locks grooved shafts, pivot pins, and linkage assemblies in place, preventing sideways movement during machine operation and helping maintain reliable stitching performance.
Is this compatible with all GK9 bag closer machines?
It is compatible with many common GK9 portable bag closer models including GK9-2, GK9-8, GK9-18, GK9-18A, GK9-200, and GK9-500. Always verify your parts manual before purchasing.
Is the circlip reusable?
If it has not been bent, stretched, or damaged during removal, it may be reused. However, replacing worn retaining clips during maintenance is recommended for reliable operation.
What tools are required for installation?
