      watts link bellcrank bearing loads

      I'm designing a watts link bellcrank to be mounted on a 9". I will be using a big bolt in single shear for the pivot but the safety factor is huge so I am not concerned (besides it looks like a common method). The links will be in double shear and either 5/8 or 3/4 rod ends. My question is the load I should design the bellcrank bearings to handle. I'm looking at opposing tapered roller bearings with seals on both sides. I was thinking that 7500 lb radial load capability might be a good point to start from. That would give me a substantial safety factor to account for impact loads, etc. Even if if the bearings did fail, the bolt would not. Does 7500 lbs sound like a good place to start?

      Thanks for any info
