Frequently asked questions about UCF204
What does the sealed design mean on a UCF204 bearing?
The UCF204 (Shaft 20mm) is supplied as a sealed unit with an integral seal configuration, which is typical for mounted and pre-lubricated designs. Confirm the seal material and relubrication access for the application. Compare seal types before deciding on the replacement.
Does the UCF204 come with C3 clearance?
This directory lists the UCF204 with CN (Standard). C3 (increased internal clearance) versions are common for higher operating temperatures, higher speeds, or press-fit arrangements — specify the required clearance on your RFQ so the quotation matches the application. Read the clearance guide.
The UCF204 is listed as a 20mm shaft pillow block bearing in sealed configuration. Part of the UCF200 series, the directory records cast iron housing + chrome steel bearing and P0 (ABEC-1) precision grade for RFQ verification.
The UCF204 uses the same part number designation across SKF, FAG, NSK, NTN, and Timken catalogs. This is a standardized pillow block bearing with industry-standard boundary dimensions. Confirm the housing style, shaft diameter, and seal type before ordering a replacement.
