FYH NA206-19 Insert Bearing, 1 3/16 in Bore, Eccentric Collar, 62 mm O.D.
Available
This page covers 11 FYH NA200 series insert bearings (NA205-16 to NA212-36) with an eccentric locking collar, bore sizes 1 to 2 1/4 in (imperial). 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.
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

Selecting the right option
Every size on this page has an imperial (inch) bore. The drop-down shows the shaft size in inches; the Model Details give the bore in mm with the inch size in brackets. Metric shafts need the metric version of the insert.
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.
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.
