| PRECISION SHAFTING - Precision case hardened and
ground shafting include C-1060 steel case hardened to Rockwell 60-65C, 440C stainless
steel case hardened to Rockwell 50-55C as well as precision ground 303 stainless steel
(262max Birnell). PRE-DRILLED SHAFTING
- Shafting is available with pre-drilled and tapped mounting holes matching our
pre-drilled shaft support rails.
Materials and Hardness:
AISI C-1060* steel, case hardened to Rockwell 60-65C
440 C stainless steel, case hardened to Rockwell 50-55C
303 stainless steel, (for use with engineered plastic bearings), has approximate hardness
of Rockwell 75-95B.
*C-1060 can be supplied with hard satin chrome finish at additional cost. (Adds .0001
to .0002 to diameter).
Finish: Normally between 10 and 16 micro-inches
RMS. Other finishes can be furnished to meet special requirements.
Length Tolerances: Shafting is stocked in 6 to 10 foot lengths, and
is supplied to required lengths
±1/16" (±1.5mm). If required, closer length tolerances can be supplied at
additional cost.
Straightness: With the exception of 1/4" and 3/8"
diameters, the standard straightness tolerance is .001"-.002" per foot
cumulative. Straighter lengths to meet more stringent requirements can be supplied at
additional cost.
Chamfered Ends: Normally, all shafts are rough cut. Precision
chamfers or other dimensions are classified as a special fabrication and carry extra
charges.
Maximum Lengths: The maximum lengths in stock for each diameter are
shown in the tables. |
