END MACHINING |
| PowerTrax™
HG hardened and ground shafting is manufactured for use with precision
linear bearings and other applications requiring an accurate, round,
hardened shaft or guide rod. All linear shafting can be machined by
Nook Industries, Inc. to any of the configurations detailed below.
To view examples of custom end machining visit our End
Machining Photo Gallery. |
| RADIAL HOLES
DRILLED AND TAPPED |
 |
Radial drilled
and tapped holes are available with either UNC or UNF Class 2B thread.
The hole alignment and location tolerance is ±.010". |
| RETAINING
RING GROOVES |
 |
Retaining ring
or other grooves area available for all diameter shafting. Annealing
may require be in the machined area. |
| THREADED
DIAMETERS |
 |
Either the
major diameter or reduced diameter may be threaded to UNC or UNF Class
2A. Threaded areas will not have full hardness. |
| FLATS – SINGLE
OR MULTIPLE |
 |
Flats have
a location tolerance of ±1/64". Multiple flats available on single
plane or different planes with location tolerance ±1/64". Contact
Nook Industries, Inc. for flat length limits. |
| COAXIAL HOLES |
 |
Coaxial holes
are machined with concentricity of .005" centered in the shaft end
for shafting 1/2 inch diameter and larger. UNC or UNF Class 2B internal
threads are available. Based on tapped hole size, some ends may require
annealing and will remain soft on the outside diameter. |
| OPTIONAL CHAMFER |
 |
Cut shafts
are supplied with Nook standard end chamfers. Specific chamfer dimensions
may be specified. |
| REDUCED DIAMETER |
 |
Single or multiple-step
machined diameters are available. Concentricity held within .002".
The reduced diameters will not have full hardness. |
| KEYWAYS |
 |
Keyways are
available for square, rectangular or ANSI Standard Woodruff keys.
Keyway diameter will not have full hardness. |
