FYH PA210 Tapped Base Pillow Block Bearing Housing, 50 mm (1 7/8 to 2 in) Shaft

The FYH PA200 is a tapped base pillow block (plummer block) bearing housing in the normal duty range. This page covers 7 housings, PA204 to PA210, for shafts from 12 to 50 mm (inch shaft sizes 1/2 to 2 in are also covered). Select the housing from the drop-down; each size has its own dimension set in the Model Details.

These tapped base pillow block housings are supplied without an insert bearing. A complete unit such as UCPA207 is the PA207 housing fitted with a UC207 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 PA207 takes UC207 on a 35 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 UC207-20). Every size on this page has an inch bore listed.

PA204 covers more than one insert size (PA204: 12, 15, 17, 20 mm): the housing is shared across those bores, so confirm the exact insert number when ordering.

This housing is tapped: the bolt holes in the base are threaded (M10x1.5, M14x2 or M16x2 by size), so no through bolts are needed.

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; an NC insert locks with a concentric collar.

The base is tapped, so the housing is bolted down from below using the thread shown for each size. Check the thread against your bolts and use J, the bolt hole spacing, to set out the holes.
