Solicitation Q&A
24-SIMACQ-D60-0004 Timken Bearings
Notice ID: N6339424Q0070
1. Question: I was able to obtain the drawing for P/N 2MM9121WICRDUl from SAM. I did not see the other two drawings listed. Are those drawings also available?
Answer: Here are the hyperlinks to TIMKEN website that has this information, including their CAD drawings for the other 2:
Part Number 2MM9116WICRDUL, Fafnir® Spindle Angular Contact Ball Bearings (9300WI, 9100WI, 200WI, 300WI) On The Timken Company
Part Number 2MM9126WICRDUL, Fafnir® Spindle Angular Contact Ball Bearings (9300WI, 9100WI, 200WI, 300WI) On The Timken Company
2. Question: Fill 1 bearing of each duplex set denoted in table with Microporous Polymeric Lubricant MPI-0779 using NAVSEA process of preload filling. Can you provide me with the NAVSEA process information?
Answer: BALL BEARING NAVSEA PROCESS: MICROPOLY MPl-0779. FILL ONE
BEARING PER SET. SPECIAL FILL AND CARVING.
3. Question: I need information from the drawing that indicates a very specific process: Fill 1 bearing of each duplex set denoted in table with Microporous Polymeric Lubricant MPI-0779 using NAVSEA process of preload filling.
Answer: We have reached out to the manufacture to confirm if the bearings already contain the MPI-0779 MicroPoly lube, the Tech Support specialists confirmed that they do not however, it is common for vendors/customers to request this process be performed by the EOM with their procurements, however it must be requested. The attached drawing has the necessary information the vendor will need to procure the appropriate TIMKEN bearings, enhanced with the MicroPoly Lube, MPI-0779. I also noticed a part number discrepancy in our REV.C drawing and have annotated this in the updated attached drawing on SAM.gov. Our engineering team will be submitting a correction for this drawing in the following weeks. To clarify a little further, it would be TIMKEN, the bearing OEM performing the enhancements of MPI-0779 application and preloading & Carving. Not the vendor. The vendor should only request this from TIMKEN for each of the bearings. I hope this clears things up. To be specific in the drawings, and what the vendor shall be procuring is:
Duplex Bearing, 2MM9116WICRDUL:
- One of the bearings in the duplex set filled with MPI-0779
- Pre-loaded to 70 lbs and carved to standard dimensions listed
- Light coat of lubricant film, NSN:8030-01-387-1131, evenly distributed (see note C)
- Torque Data and Certificated of Conformance shall be supplied with every unit (see note F)
Duplex Bearing, 2MM9121WICRDUL:
- One of the bearings in the duplex set filled with MPI-0779
- Pre-loaded to 135 lbs and carved to standard dimensions listed
Duplex Bearing, 2MM9126WICRDUL:
- One of the bearings in the duplex set filled with MPI-0779 (see note G)
- Pre-loaded to 200 lbs and carved to standard dimensions listed (see note E)
