FYH SB207-23 Insert Bearing, 1 7/16 in Bore, Set Screw, 72 mm O.D.

This page covers 7 FYH SB200 series insert bearings (SB201-8 to SB207-23) with set screws, bore sizes 1/2 to 1 7/16 in (imperial). Choose the size from the drop-down: each variant has its own dimensions, load ratings and mass in the Model Details.

The SB insert has a narrower inner ring than the UC of the same size number. Load ratings are given for each size in the Model Details; the SB201 to SB203 ratings are lower than the UC of the same number, while SB204 and up are the same as the UC of the same number. It is the replaceable bearing inside a plummer block (pillow block), flange or take-up unit.

Key specifications

Available sizes

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.

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 SB series is offered in re-lube and sealed-for-life styles. The model numbers on this page do not show which style a size is.

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.
