FYH UC206 Insert Bearing, 30 mm Bore, Set Screw, 62 mm O.D.

This page covers 18 FYH UC200 series insert bearings (UC201 to UC218) with set screws, bore sizes 12 to 90 mm (metric). Choose the size from the drop-down: each variant has its own dimensions, load ratings and mass in the Model Details.

An insert bearing is the replaceable bearing inside a plummer block (pillow block), flange or take-up unit. UC type inserts have a wide inner ring and a spherical O.D., so they seat 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
• Fans, blowers and pumps
• Agricultural, construction and general industrial machinery

Features

• Wide inner ring with set screws (FYH Bullet Point type) spaced 120 degrees apart to lock the insert on the shaft
• Spherical O.D. with a grease groove and grease holes, so the insert can be re-lubricated when it is in a housing
• Rubber seal with metal slinger, supplied pre-lubricated with FYH grease
• Basic dynamic load rating Cr 12.8 to 96.1 kN and static rating C0r 6.65 to 71.5 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.

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.

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.

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.
