Sealmaster ST-20T Take-Up Ball Bearing Unit Skwezloc

The Sealmaster ST-20T Take-Up Ball Bearing Unit is a side-mount, wide-slot take-up assembly designed to move and tension conveyor shafts with precise alignment. It features a cast-iron housing and a 1-1/4 in bore, using 52100 bearing steel components with a black oxide coating, and it employs the SKWEZLOC concentric locking collar for near-perfect shaft-to-bore concentricity. This Gold Line standard-duty unit carries a felt labyrinth seal for long life in demanding environments and is commonly paired with ST-series take-up frames, such as the STH-20 center-pull style, for reliable belt tension adjustments. Typical overall dimensions are around 5-1/16 in in length, 1-3/4 in in width, and 4 in in height, with a dynamic load rating near 5,782 lb depending on mounting and service conditions, and operation from -20 to 220 degrees F. The combination of cast-iron construction, precision SKWEZLOC locking, and the standard side-mount configuration makes the ST-20T a robust choice for mid-range take-up applications where consistent belt tension and shaft alignment are critical.
