The 1-1/2" Steel (Black Oxide) Adjustable Thrust Collar Assembly is a precision shaft-mounted component designed for controlled axial positioning and secure load holding. Its two-piece knurled collar design clamps directly to the shaft and uses a male-female connecting hub to provide infinite adjustment in either direction, with wrenching flats for added tightening torque. Made from black oxide steel, it delivers high axial holding power, durability, and reliable performance. With adjustable travel ranging from 3/8" to 3/4" depending on bore size, it is ideal for applications such as bearing preloading, shaft positioning, motion control systems, automation equipment, and machinery requiring precise axial adjustment. The adjustable thrust collar assembly is available in steel and stainless steel.
