Aurora Bearing Company CW-5ETS Pillow Block Bearing

CW-5ETS is the studded variant of Aurora Bearing Company’s CW-5ET stainless steel rod end bearing in the CW-ET series, engineered for compact articulating joints in industrial machinery. The unit uses a PTFE-lined insert and is built from 17-4 PH stainless steel, offering corrosion resistance and smooth motion in demanding environments. Key dimensions include a 0.3125 in bore, a ball diameter of 0.593 in, a base-to-center distance of 1.375 in, a head diameter of 0.875 in, a shank diameter of 0.500 in, and an approximate weight of 0.08 lb; the standard thread is 5/16-24 UNF-2B with a thread depth around 0.687 in and wrench-flat width of 0.437 in. The CW-ET family provides a misalignment angle up to 18 degrees and a radial static load capacity of about 6,451 lbs. The suffix “S” indicates a studded configuration, available by request (as with CW-8ETS), enabling mounting via a stud rather than internal female threads.
