80 Advanced Design Thrust Bearings These Advanced Design Thrust Bearings from DX Engineering improve on the standard design in two key areas. First, the ball bearings ride on an all-metal surface, not a seam like other thrust bearings, to promote a longer service life. The precision bearings are made to much tighter tolerances, eliminating the slop found in other thrust bearings. Secondly, our Mast Thrust Bearings can handle much greater static loads than other models. Not only does that reduce stress on the rotator, it makes rotator service possible without removing your antenna—think about how much hassle, time and money that could save! They fit either a 2" or 3" OD mast and most common tower sizes from Rohn and American Tower.

DX Engineering’s Tower Accessory Shelves are simpler to install and feature a thicker, stainless steel plate for greater stability. The DXE-AS-455G works with both 45G and 55G towers. It lets you easily mount rotators and thrust bearings thanks to its innovative multi-piece design. The shelf is bolstered by three adjustable, stainless steel corner brackets bolted to the plate.
