📖 Reading the Part Number

Every FYH part number follows the JIS B 1557 system, so the SKU itself describes the product. Reading UKFL306 from left to right: UK is the bearing insert — a tapered-bore insert mounted with an adapter sleeve. Instead of set screws, the bearing is drawn up a tapered sleeve that grips the shaft evenly around its full circumference — the best concentricity of any locking style, favored for higher speeds and reversing loads. FL is the housing — an oval two-bolt flange — the compact flange choice where mounting space is tight. The first digit of the number block, 3, is the diameter series — Series 3, the heavy-duty line with the largest balls and deepest raceways for maximum load capacity. The bore code sets the shaft size: for codes 04 and above, multiply by 5 — here, a 30 mm shaft. (Codes 00–03 map to 10, 12, 15, and 17 mm.)

❓ Common Questions

What standard is the UKFL306 built to?

What shaft size does the UKFL306 fit?

The bore code decodes to a 30 mm shaft. Always measure your shaft before ordering — metric and inch bores can look deceptively similar.

Can I get help cross-referencing a competitor part number?

Yes — FYH units interchange dimensionally with most industry-standard mounted bearings. Send us the number on your old unit through the Contact Us Form and we’ll cross it.
