SKF SY 3 4 TF VA228 Self-Aligning Ball Bearing

SKF SY 3/4 TF/VA228 is a self-aligning Y-bearing pillow block unit with a 3/4 in bore (19 mm), designed for misalignment tolerance in rotating shafts. Housed in gray cast iron, it uses a two-bolt base for secure mounting and a fixed (non-expansion) inner bearing. The unit houses a Y-bearing self-aligning ball bearing that accommodates angular shaft misalignment while carrying radial loads common in industrial machinery. The TF/VA228 variant is specified for high-temperature service as part of SKF's high-temperature bearing family, with operating temperatures up to 350 °C (660 °F). The housing is relubricatable through a grease fitting in the unit, enabling maintenance without disassembly. This compact, integrated pillow block solution provides robust shaft support, reliable lubrication access, and tolerance for thermal growth in demanding environments.
