Available
This page covers 7 FYH SA200 series insert bearings (SA201 to SA208) with an eccentric locking collar, bore sizes 12 to 40 mm (metric). Choose the size from the drop-down: each variant has its own dimensions, load ratings and mass in the Model Details.
An eccentric collar insert locks to the shaft with a collar that turns against the inner ring. It is the replaceable bearing inside a plummer block (pillow block), flange or take-up unit, and the spherical O.D. seats in a housing with a matching spherical bore.

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.
The catalogue offers the SA series in a re-lube style (grease groove and holes on the O.D.) and a sealed-for-life style. The model numbers on this page do not carry the letter that marks the style.
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.
Fit the collar against the inner ring so the eccentric surfaces engage, then tighten the set screw in the collar.
The spherical O.D. seats in a housing with a matching spherical bore.
