FYH UK210 Tapered Bore Insert Bearing, 45 mm Shaft with Adapter Sleeve, 90 mm O.D.

This page covers 13 FYH UK200 series insert bearings (UK205 to UK218) with a tapered bore for an adapter sleeve, shaft sizes 20 to 80 mm (metric). Choose the size from the drop-down: each variant has its own dimensions, load ratings and mass in the Model Details.

The UK type has a tapered inner ring (taper 1:12) and uses a separate H2300X adapter sleeve to match the shaft size and mount the insert. It is the replaceable bearing inside a plummer block (pillow block), flange or take-up unit.

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

• Tapered bore (1:12) with a separate adapter sleeve that matches the insert to the shaft size
• The tapered bore and adapter sleeve give 360 degree shaft contact along the whole inner ring
• Suited to applications where shock loads may damage other locking devices
• Spherical O.D. with a grease groove and grease holes; rubber seal with metal slinger; supplied pre-lubricated with FYH grease
• The insert and the adapter sleeve are separate items and are ordered separately
• Basic dynamic load rating Cr 14 to 96.1 kN and static rating C0r 7.85 to 71.5 kN (see the Model Details for each size)

Selecting the right option

Every size on this page is a metric size: the drop-down shows the shaft diameter in mm that the adapter sleeve fits. For an inch shaft, the inch adapter sleeve code depends on the shaft size (the catalogue adapter table uses HE, HS or HA codes, for example HE2306X for 1 in, HS2306X for 7/8 in and HA2306X for 15/16 in). See the adapter sleeve pages below.

The shaft size is smaller than the tapered bore of the insert: for example, the UK206 has a 30 mm tapered bore and fits a 25 mm shaft with its adapter sleeve. Order the adapter sleeve with the insert, because they are two separate items.

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.

Order the insert and its adapter sleeve together, because they are two separate items.

Match the insert to a housing with the same size number: the spherical O.D. seats in a matching spherical housing bore.

The catalogue unit tables pair these inserts with these FYH housings (matched by size number): P200 series pillow block (plummer block) housings (13 of 13 sizes), F200 series four bolt flange housings (11 of 13 sizes), FL200 series two bolt flange housings (13 of 13 sizes), FC200 series round flange cartridge housings (13 of 13 sizes) and T200 series take-up housings (9 of 13 sizes). A tapered bore insert needs an adapter sleeve, which is a separate item: see the H2300 series adapter sleeves (metric shafts), or the HE2300 series adapter sleeves for inch shafts (some inch sizes use HS or HA codes).
