محور قفل، ذيل المخرطة، كروم

I was a bit nervous ordering a replacement part online, but this locking axis matched the SC4 diagram perfectly and the chrome finish has held up well under regular use. The locking mechanism feels solid and precise on my lathe.

The chrome finish looks factory-fresh, and it locked into my 7550 lathe’s tailstock without any wobble. Install took under five minutes since the threads matched the original part perfectly.

Finally, a locking axis that actually holds firm on my bench lathe without any play. The chrome finish is a nice touch and it slides in perfectly as a direct replacement for the worn-out original.
