FYH T318 Take-Up Bearing Housing, 90 mm (3 1/2 in) Shaft

The FYH T300 is a cast iron take-up (take up bearing) bearing housing in the heavy duty range. This page covers 19 housings, T305 to T328, for shafts from 25 to 140 mm (inch shaft sizes 1 to 4 in are also covered). Select the housing from the drop-down; each size has its own dimension set in the Model Details.

These take up bearing housings are supplied without an insert bearing. A complete unit such as UCT314 is the T314 housing fitted with a UC314 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 T314 takes UC314 on a 70 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 UC314-44). Sizes without an inch bore in the unit tables: T306, T307, T310, T316, T317, T322, T324, T326, T328.

The first option on this page is catalogue dimension N for each housing, in mm.

The catalogue also lists T319 and T321, which are not part of this page.

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.

This is the wide-slot take-up style for a side-mount take-up frame. Check the dimensions in the Model Details against your frame before ordering.
