RBC Bearings Corporation S40Lw Cam Follower Bearing

S40LW RBC Bearings Cam Follower is a standard-stud, hex-head, sealed cam follower bearing built around a needle-roller element for low-friction motion along a cam profile. It features a 1.250-inch roller diameter and a 0.750-inch roller width, delivering a compact footprint suitable for tight machine layouts, with a stud diameter of 0.500 inches and a stud length of 1.250 inches for a robust mounting interface. The bearing is constructed from chrome steel (52100 bearing quality material), providing the hardness and wear resistance needed for repetitive cam loading. Sealed design protects the needle-roller assembly from contaminants while retaining lubrication, helping extend service life in demanding operating environments. This configuration is specifically described as a standard stud type with hex head and sealed ends, making installation straightforward in a variety of cam-driven applications where reliable, smooth movement is essential.
