Selecting the right option
This page is for the single model SB208-24, with a 1 1/2 in bore. If you need another shaft size, the related pages below list the other sizes in this range.
Imperial (inch) bores are in fractions of an inch; the Model Details give the size in mm with the inch size in brackets: match the bore to the shaft you have.
The catalogue offers the SB series in re-lube and sealed-for-life styles. This model number does not show the style, so ask AIMS first if re-lubrication matters.
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.
The spherical O.D. seats in a housing with a matching spherical bore. Ask AIMS to confirm the housing for your insert before ordering.
If you are unsure which insert suits a shaft and housing, send AIMS the part numbers or sizes and we will confirm the fit.
