I would like to know the actual bearing numbers for the relevant bearings used in the Simplex Projectors and Soundheads. The part numbers in the parts cataloque only list the part number and not the actual bearing number. Most of the bearings would actually be available off the shelf at most bearing supply companies if one knew the bearing number. We would lose shows if we dismantled over-night and had to purchase the bearings after opening time of the bearing supply company, there would not be enough time to reassemble before the first scheduled show time. Having to purchase the bearings from the manufacturer would add three to four times the shelf price of a local company.HORIZONTAL MAIN DRIVE ASSEMBLY
P-1409 - ball bearing - 6201/03
P-6639 - ball bearing - VERTICAL SHAFT ASSEMBLY
P-1409 - ball bearing - 6201/03
P-1412 - ball bearing - SHUTTER AND FRAMING ASSEMBLY
P-1481 - shaft ball bearing - rear -
P-1482 - shaft ball bearing - front -
P-1483 - spline ball bearing - 5 STAR SOUNDHEAD
SCANNING DRUM SHAFT ASSEMBLY
P-2199 - ball bearing - SPROCKET SHAFT ASSEMBLY
P-7014 - ball bearing - If anybody can fill in the blanks it would be greatly appreciated. Michael.

While their are cross references for many of the bearings, generally Strong does not really over charge for their bearings (certainly not 3 to 4 times street price).I know of no published list of Simplex bearing cross references. Furthermore, just having the actual sizes doesn't dictate the duty of the bearing. Also cheaper bearings may also be cheaper quality. There are some that are the same sizes (like R-4 or R-7) but differ in their packing, shielding and friction. A Christie payout bearing and a Century BG-259 and a Simplex P-3368 are all the same size but put the Century or Simplex bearing in the Christie centerfeed and the feed fingers won't move on their own. Likewise, use the Christie bearing and in the Century/Simplex application and it will wear out prematurely. Steve ------------------
