FYH SC203 Insert Bearing, 17 mm Bore, Spherical O.D., 40 mm O.D.
Available
This page covers 2 FYH SC200 series insert bearings (SC203 to SC204) with a non-extending inner ring and a spherical O.D., bore sizes 17 and 20 mm (metric). Choose the size from the drop-down: each variant has its own dimensions, load ratings and mass in the Model Details.
The SC insert has a non-extending inner ring and a spherical O.D., so it mounts in a traditional housing, and its bore tolerance is more precise than typical mounted bearings, which allows press-fit shaft mounting.
Where this product is used
- Replacement insert for a plummer block or pillow block unit
- Replacement insert for flange and take-up housings with a matching spherical bore
- Conveyor rollers, drive shafts and idler stations
- Fans, blowers and pumps
- Agricultural, construction and general industrial machinery
Features
- Non-extending inner ring with a spherical O.D., so it mounts in a traditional housing
- More precise bore tolerance than typical mounted bearings, which allows press-fit shaft mounting
- Light duty series
- Basic dynamic load rating Cr 9.55 to 12.8 kN and static rating C0r 4.8 to 6.65 kN (see the Model Details for each size)

Selecting the right option
Every size on this page has a metric bore (shaft sizes in mm). Match the bore to the shaft you have: an inch shaft needs the imperial version of the same insert, which is a different size.
SC inserts have a spherical O.D. and a non-extending inner ring with no built-in locking device, so the shaft is press-fitted. If you need a built-in locking method, see the related pages below.
Fitting and use
Check the load against the catalogue figures in the Model Details before ordering, and apply a suitable safety factor.
Because the inner ring is non-extending, plan for a press fit on the shaft, and keep the housing bore matched to the spherical O.D.
If you are unsure which insert suits a shaft and housing, send AIMS the part numbers or sizes and we will confirm the fit.
