I've posted over @ RFQ - thought I'd set up here too.

The items to be manufactured will be less than 8 inches long, each end splined. One end having 41 splines, the other end has 17. A bearing surface is required to match a set of roller bearings. An image (paste up) of the completed item is provided below.

APPROXIMATE DIMENSIONS:
OVERALL
LENGTH: 7.25” (approximate)
Length of 17 Splines: 2”
Length of 41 Splines: 2.5”
DIAMETER of Shaft (and major diameter of Splines): 1.25”

BEARING SURFACE
LENGTH: 1.125”
DIAMETER: 1.375”

Request you provide materials for this job. These units should be made of 4140/4340 or similar. These will be used in performance race cars and subjected up to 600 HP and 500FtLbs torque. Heat treating will be required, although may be accomplished separately by another vendor if necessary - please indicate if you do/do not have this capability.
After RDT&E, and market analysis supports developing additional units, small production runs using 300M may be required.

DELIVERABLES for this REQUEST:

  1. Cost estimate for producing 4 prototypes
  2. Indicate if heat treatment is included - or to be accomplished by another party/vendor
  3. Method used for manufacturing the dual spline output shafts, i.e., hobbing, cold roll, or other (disc cutter, etc)
  4. Recommended HP limit if applicable (for DT&E the limit will be 450 HP)
  5. Timing from receipt of order to shipping
  6. Indicate if interested in producing the prototypes only, or ability to support small production runs. If interested in production, please provide cost estimate for producing in 300M, in lots of 4, 10, 20 units, or suggest lot sizing for most economical, small lot production
  7. Any suggestions, recommendations, regarding material selection, manufacturing, heat treatment, distribution, etc. would be greatly appreciated



This RFQ will last approximately 2 weeks (ending 5 Sep 2014)

Shipping should be within 5 business days of order.



PAYMENT
Payment will be via PayPal or credit card.


If you are interested in responding, I will provide an image to better describe the final items. PM me here.

Thank you - Jim
