This Shellplate Bearing Kit smooths indexing and reduces play and wobble in the shell plate of Dillon BL 550, RL 550, XL 650 and SL 900 presses. It also reduces the "snap" when the index ball engages the shellplate … greatly reducing powder loss from cases on the shellplate.

Included in Kit:
— 1 Oilite® Plus Oil/Teflon® Lubricated Thrust Bearing
— 1 Polyamide-imide Index Ball
— 1 Reduced Tension Index Ball Spring (Stainless Steel)
— 2 Index Ball Spring Adjustment Washers (Stainless Steel)
— Instructions

✓ Works on BL 550, RL 550, XL 650 and SL 900 presses.

Easy Drop-In Installation
The custom reduced tension index ball spring means you don't have to worry about cutting the OEM spring. Just drop it into place and you are good to go! If your feel that the spring is too light, two washers are included to incrementally increase the spring tension. The spring and washers are stainless steel for corrosion resistance.

Polyamide-Imide Index Ball
The polymer Index Ball is a fraction of the mass of the OEM steel ball (0.62g versus 3.52g). That is 92.4% lighter! Due to the lower mass, it doesn't violently hammer the bottom of the shellplate when it engages the detent … and thus doesn't toss powder out of the case. The Polyamide-imide ball is also much harder and more wear resistant than balls made from other plastics (e.g. Delrin®).

Oilite® Plus Bearing
The Oilite® Plus Thrust Bearing is sintered bronze lubricated with Oil/Teflon®. It never needs lubrication and the Teflon® reduces friction 17% compared to a standard oil lubricated Oilite® bearing.
It is also thinner than other bearing kits using a needle roller bearing … yielding more engagement of the shellplate bolt threads in the ram.

Big differenceThis made a big difference, really smoothed out the press Written by Aaron on Mon 19 Oct 2020 1:23:52 AM GMT

OMG! What a differenceCombined with the Bearing Cam Rod, this smoothed out everything on the press. Indexes better, reduced drag on the cycle (as felt in the handle). Made my press a "dream machine" Written by Kevin Gourley on Thu 16 Apr 2020 6:26:03 PM GMT
