R & XP Machine Ballscrew Couplings
In Early 1980's, Strippit Solved a Persistent Machine Problem with Keyed-Ballscrew Couplings by Upgrading to New Keyless-Couplings which did Not get Sloppy Loose Keys, and Fall-Apart.
In 1990, Strippit Introduced the R & XP Machines. To make Machines Cheaper, Strippit Stupidly went Backwards to Old Keyed-Couplings again, and "Duh!", Same Old Problems came Back.
If you have Loose, Broken, Falling-Apart Ballscrew Couplings causing Tolerance Problems or Worse, Replace it with Our Keyless-Coupling, which has 2 Advantages;
1 -- It has a Higher Tork-Rating than Original Coupling, making it Much more Durable.
2 -- It Clamps onto Motor & Ballscrew Shafts, even if Shafts are "Less than Perfect"
from Damage caused by Old Coupling.
Just Clean-Up any Burrs & Rough-Spots on Shafts with a Flat-File, Slide Coupling On Shafts,
Center Coupling Between Shafts, and Tighten Lock-Collars at each end.
No More Keys to Fit & Install. No more Keys to Rock Back & Forth and get Loose.
There are Many Misprint-Mistakes in Strippit's Part Manuals. In 1 "R-Machine" Parts Manual, this Same X & Y Axis Ballscrew Coupling is Listed as #120823-000, #120832-000, and #120382-000 !
To make Sure you get Correct Coupling, Measure Both Your Motor & Ballscrew Shafts.
Most of these Machines have .750" Motor-Shaft and .718" Ballscrew-Shaft Diameters,
and that is the Coupling we Stock, though we can Make any Coupling you might want.
