UCFL 205 CT 25 mm Two-Bolt Flange Bearing Unit

UCFL 205 CT 25 mm Two-Bolt Flange Bearing Unit

UCFL 205 CT is a complete two-bolt flange bearing unit designed for mounting on a nominal 25 mm shaft. The standard UCFL205 configuration combines a UC205 insert bearing with an FL205 oval flange housing, creating a compact ready-to-install bearing unit for rotating shaft systems.

The basic construction is:

UC205 insert bearing + FL205 flange housing → UCFL205 bearing unit

The key product identification is:

UCFL 205 CT → 25 mm shaft → UC205 insert bearing → FL205 housing → two-bolt oval flange → set-screw shaft locking

UCFL 205 dimensions

The principal mounting dimensions of the standard UCFL205 size are:

The most important dimensions when identifying the complete unit are:

25 mm shaft + 130 mm flange length + 68 mm housing width + 99 mm bolt-hole spacing + two mounting holes

What does UCFL205 mean?

The designation:

UCFL205

identifies a complete mounted bearing unit rather than only the bearing insert.

The designation can be understood as:

UC205 – insert bearing

FL205 – two-bolt oval flange housing

Together:

UC205 + FL205 → UCFL205

This distinction is important when ordering replacement components.

If only the bearing insert is required, the relevant designation is UC205.

If the complete bearing and housing assembly is required, the designation is UCFL205.

UC205 insert bearing

The functional bearing element inside the UCFL205 assembly is the:

UC205 insert bearing

designed for a nominal:

25 mm shaft.

UC-series insert bearings feature an extended inner ring and are commonly secured directly to the shaft using set screws.

This locking method allows the inner ring to be fixed to the shaft after the bearing unit has been positioned correctly.

FL205 two-bolt flange housing

The second main component is the:

FL205 housing.

FL-series housings use a characteristic oval two-bolt flange design.

For the UCFL205 size, the principal mounting dimensions are approximately:

shaft diameter 25 mm
overall flange length 130 mm
housing width 68 mm
bolt-hole centre distance 99 mm
mounting holes approximately 16 mm

The two mounting points allow the housing to be bolted directly to a suitable machine surface.

Self-aligning bearing-unit design

UC-series insert bearings used in flange units have a spherical outer surface that operates in a correspondingly shaped housing seat.

This construction allows the bearing unit to accommodate small initial mounting misalignments between the shaft and housing.

This self-aligning capability should not be interpreted as allowing unlimited shaft misalignment.

Correct shaft alignment, housing installation and mounting geometry remain important for reliable bearing operation and service life.

How is UCFL 205 secured to the shaft?

The UC205 insert bearing uses set screws located in the extended inner ring.

After the unit has been correctly positioned on the shaft, the set screws are tightened against the shaft surface to secure the inner ring.

This is one of the characteristic locking methods used with UC-series insert bearings.

The complete assembly therefore provides two different mounting functions:

housing → bolted to the machine structure

and:

bearing inner ring → secured to the shaft with set screws

UCFL205 vs UC205

These two designations should not be confused.

UC205 refers to the bearing insert itself.

UCFL205 refers to the complete flange bearing unit containing the UC205 insert and FL205 housing.

Therefore:

UC205 ≠ UCFL205

but:

UC205 + FL205 = UCFL205

If a complete two-bolt flange unit is required, UCFL205 is the relevant product type.

UCFL205 vs UCP205

UCFL205 and UCP205 can both use bearing inserts designed for a 25 mm shaft, but the housing designs are different.

UCFL205 uses an oval two-bolt flange housing.

UCP205 uses a pillow block / pedestal housing.

Therefore, the complete units are not automatically interchangeable simply because their bearing inserts have the same shaft diameter.

UCFL205 vs UCF205

UCFL205 should also be distinguished from:

UCF205

The UCFL series uses an oval two-bolt flange housing, while the UCF series uses a different flange geometry and mounting-hole arrangement.

When replacing a complete mounted bearing unit, check:

• shaft diameter,
• housing shape,
• number of mounting holes,
• bolt-hole spacing,
• overall housing dimensions,
• locking method,
• bearing insert specification.

Radial loads and shaft support

The UC205 insert is based on a ball-bearing design used to support rotating shafts.

The bearing primarily supports radial loads, while its ball-bearing geometry can also accommodate axial loading within the limits specified for the exact bearing design.

Specific dynamic and static load ratings should not be assigned to the CT UCFL205 using another manufacturer's catalogue values.

For engineering selection, load ratings should be confirmed from CT technical documentation.

Where are UCFL 205 bearing units used?

Two-bolt flange bearing units of the UCFL type are widely used to support rotating shafts in machinery such as:

conveyors, agricultural machinery, production equipment, packaging machines, rollers, fans, auxiliary drives and general industrial machinery.

The oval two-bolt housing is particularly useful where the bearing unit needs to be mounted directly to a flat machine surface using two fixing points.

Suitability for a particular application should be determined from actual operating load, speed, temperature, shaft arrangement, lubrication and environmental conditions.

How to select a replacement for UCFL 205 CT

Do not select a replacement using the 205 number alone.

Check at least:

1. nominal shaft diameter 25 mm
2. bearing-unit type UCFL
3. two-bolt oval flange configuration
4. overall flange length approximately 130 mm
5. housing width approximately 68 mm
6. bolt-hole centre distance approximately 99 mm
7. mounting-hole diameter approximately 16 mm
8. insert bearing type UC205
9. set-screw shaft locking
10. load ratings and operating parameters of the replacement manufacturer.

Standardised mounting dimensions can make products from different manufacturers dimensionally similar, but this does not automatically guarantee identical operating performance.
