This SKF bearing lot comprises two inch-series Y-bearing pillow-block units: the SY 1.3/16 TF (often listed as SY1-3 16TM) and the SY 1-1/4 TF (SY104 1-1/4). Both are Y-bearing pillow-block housings designed to accept SKF Y-bearing inserts for shaft support in inch-based machinery, with the SY 1.3/16 TF offering a compact option and the SY 1-1/4 TF providing a larger bore for higher stiffness. This mix reflects SKF's SY line of inch-series bearing housings, commonly used in light- to moderate-duty industrial setups where quick replacement and standard mounting patterns are desirable.
