FYH FCX05 Round Flange Cartridge Bearing Housing, 25 mm (1 in) Shaft

The FYH FCX is a cast iron round flange cartridge bearing housing in the medium duty range. This page covers 7 housings, FCX05 to FCX11, for shafts from 25 to 55 mm (inch shaft sizes 1 to 2 1/4 in are also covered). Select the housing from the drop-down; each size has its own dimension set in the Model Details.

These round flange cartridge housings are supplied without an insert bearing. A complete unit such as UCFCX08 is the FCX08 housing fitted with a UCX08 insert bearing, which is ordered separately (see Related products). This page mixes metric and inch shaft sizes, because the matching inserts come in both bore types: the Shaft Diameter option gives the metric size first and the inch sizes in brackets.

Key specifications

Available sizes

Dimensions in mm. Letters follow the catalogue dimension drawings; the full set of dimensions, with inch values, is in each size's Model Details.

Selecting the right option

Match the housing to the insert bearing and the shaft. The catalogue unit tables pair each housing number with specific insert bearings; for example FCX08 takes UCX08 on a 40 mm shaft.

The page lists metric and inch shaft sizes together. Choose the metric size for a metric shaft; for an inch shaft pick the same housing and order the insert with the matching dash number (for example UCX08-24). Every size on this page has an inch bore listed.

The Bolt Size option is the mounting bolt for the housing, as listed in the catalogue unit tables (inch equivalent in the Model Details).

Not sure which insert or housing suits your shaft? Send us the shaft diameter and mounting details and we will confirm the match.

Fitting and use

The housing is supplied without an insert bearing. Order the insert separately and lock it to the shaft in the way its own type requires: a UC insert locks to the shaft with two set screws; a UK insert is a tapered bore insert that mounts on the shaft with an adapter sleeve.

The pilot (spigot) on the back of the housing locates in a bore in your frame. Check the pilot diameter H3 in the Model Details against that bore, and set out the four bolt holes on the bolt circle diameter J (J1 is the spacing between adjacent holes).
