Seal Master Spherco TREL-16 Relay

SealMaster Spherco TREL-16 rod end bearing from Sealmaster/Spherco (RBC Bearings) is a precision three-piece spherical rod end designed for rugged linkages in industrial machinery. The male rod end features a 1.000 in bore and left-hand UNF-3A 1-1/4-12 thread, with a non-lubricated configuration, and a robust carbon steel housing paired with a 52100 alloy steel ball and brass race. This Spherco TRE L-series part delivers a 28,400 lbf radial static load capacity, operates up to 250°F, and presents a 2.75 in head diameter, 1.0 in bore, 1.875 in ball diameter, and an overall height of 5.50 in, with a weight of about 2.48 lb. It embodies heat-treated construction, chrome-plated ball, and protective coatings for corrosion resistance, making it suitable for high-load linkage applications in automation, equipment, and machinery where precise angular motion is required.
