I am in the process of designing a rotating Rohn 55 tower. The
overall height will be 130'. The first 40' of the tower will be
stationary with the upper 90 feet being rotary.
Anyone have any suggestions on an appropriate (and safe) bearing to
use? I have looked into good quality, self-aligning, Browning tapered
roller bearings. These bearings are very heavy duty and have
excellent thrust ratings. They will, no doubt, do the job but they
come with a hefty price tag...$375 + shipping for one with a 2.5"
I have designed the rotating pieces such that a bearing failure will
not cause the tower to come down. A bearing failure, though, would
still be a major hassle....the tower would almost certainly have to
come down to make repairs.
Anyone have any ideas on something that will do a good job but cost
Thanks and 73....Dave/WA0FLS
