FYH SSUC203 Insert Bearing, 17 mm Bore, Stainless Steel, Set Screw
Available
This page covers 24 FYH SSUC stainless steel insert bearings with set screws (grub screws): 12 metric bores and 12 imperial bores. Choose the size from the drop-down, then check the Model Details for the bore, dimensions and ratings of that exact model number.
An insert bearing is the replaceable bearing inside a plummer block (pillow block), flange or take-up unit. UC type inserts have a wide inner ring and a spherical O.D., so they seat in a housing with a matching spherical bore. The UC-S6 type is the stainless steel series, built in the same design as the standard UC insert.

A dash means the catalogue gives no figure for that exact model number, so none is shown. For SSUC201, SSUC201-8, SSUC202, SSUC202-10 and SSUC203 the catalogue has no row under that model number, so only the bore is shown; ask AIMS for their dimensions.
Selecting the right option
This page mixes metric and imperial bores: sizes 12 to 60 mm are metric, and the fractional inch sizes (for example 1/2 in or 1 7/16 in) are imperial. Check the unit in the drop-down against your shaft before ordering.
Set screw (grub screw) inserts lock to the shaft with set screws spaced 120 degrees apart, so they suit a plain shaft of the matching bore size.
The dimensions, load ratings and speeds shown for SSUC models are those of the matching size in the catalogue UC-S6 (stainless steel series) table. They are lower than the standard UC ratings of the same size, so use these figures and not the UC200 ones. The catalogue places the S6 stainless insert in its corrosion resistant series; the housing is sold separately, so check its material suits the application too.
Fitting and use
Check the load and speed against the catalogue figures in the Model Details before ordering, and apply a suitable safety factor. The allowable rotating speed in the catalogue is a standard value: it falls to 80% for units fitted with covers, and a loose fit between shaft and inner ring reduces it further.
Tighten the set screws once the insert is in position on the shaft.
Match the insert to a housing with the same size number: the spherical O.D. seats in a matching spherical housing bore.
If you are unsure which insert suits a shaft and housing, send AIMS the part numbers or sizes and we will confirm the fit.
