Steve, When I was building my tower#2 in 2008, I considered buying a Rohn TH-3 thrust bearing (about $200+) and was advised to look in ebay. I found a nice 3-inch ball-bearing radial-thrust bearing for about $35 (brand new). It has a zerk fitting for a grease gun to maintain the lubrication (which at the slow rotation of antennas is almost never). Ebay might be cheaper than a re-build. 73, Ed - KL7UW 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-testing*, 3400-?
