What Is FAG UCFL205-J7?

FAG UCFL205-J7 is a complete housed bearing unit, not a standalone bearing.

The assembly consists of:

UC205 – radial insert ball bearing

and:

FL205 – 2-bolt flange housing.

Together, these components form a ready-to-install bearing unit for a nominal:

25 mm shaft.

For correct product identification, it is important to distinguish between:

UC205 = insert bearing only

FL205 = flange housing

UCFL205-J7 = complete FAG bearing unit.

FAG UCFL205-J7 Dimensions

The key mounting dimensions are:

d = 25 mm – bearing bore / nominal shaft diameter

130 mm – overall housing length

68 mm – flange width

J = 99 mm – mounting-hole centre spacing

16 mm – mounting-hole diameter

U = 35.8 mm – overall axial width

Number of mounting holes:

2

For a complete UCFL205-J7 flange bearing unit, identifying the product by only three dimensions is not sufficient.

A more useful mounting description is:

25 mm bore + 130 mm housing length + 68 mm flange width + 99 mm bolt spacing + 2 x 16 mm mounting holes.

FL205 2-Bolt Flange Housing

FAG UCFL205-J7 uses an FL205 cast-iron flange housing.

The housing has an elongated 2-bolt configuration with one mounting hole on each side of the bearing axis.

This is one of the main identifying characteristics of the UCFL series.

The design is fundamentally different from the square four-bolt housing used in the UCF series.

When replacing the complete unit, verify:

housing geometry

overall housing length

flange width

mounting-hole spacing

mounting-hole diameter

and:

number of mounting points.

UC205 Radial Insert Ball Bearing

The bearing insert installed in FAG UCFL205-J7 is:

UC205.

Its nominal bore diameter is:

25 mm.

UC205 belongs to the radial insert ball bearing family and is designed for installation in a compatible housing.

The insert has a spherical outside surface that operates against the corresponding spherical seat in the housing.

This bearing-to-housing geometry allows the assembled unit to compensate for limited static mounting misalignment.

It should not be confused with the internal self-aligning principle of a conventional double-row self-aligning ball bearing.

Shaft Location by Set Screws

The UC205 insert is secured to the shaft by set screws located in the inner ring.

Common search terminology includes:

set screw locking

set screw bearing

grub screw bearing

and:

grub screw locking.

The shaft-locking method is an important selection parameter.

A 25 mm flange bearing unit using another shaft-location system should not automatically be considered interchangeable with FAG UCFL205-J7.

FAG UCFL205-J7 vs UCF205-J7

This distinction is important when searching for the correct bearing unit.

UCFL205-J7 uses an:

elongated / oval FL205 housing with 2 mounting holes.

A:

UCF205-J7

uses a:

square F205 housing with 4 mounting holes.

Therefore:

UCFL205 ≠ UCF205.

Both may use the same nominal bearing size and shaft diameter, but their housing geometry and mounting arrangements are different.

FAG UCFL205-J7 vs UC205

These references identify different products.

FAG UC205

is the insert bearing itself.

FAG UCFL205-J7

is the complete assembly:

UC205 insert + FL205 flange housing.

If only the insert requires replacement, UC205 is the relevant bearing reference.

If the complete 2-bolt flange unit is required, the correct product is:

FAG UCFL205-J7.

What Does J7 Mean in FAG UCFL205-J7?

J7 is part of the exact FAG execution designation and relates to the bearing-to-housing fit.

It should not be interpreted as:

25 mm shaft diameter

C3 radial internal clearance

or:

bearing precision class.

When the exact FAG unit is required, retain the full reference:

FAG UCFL205-J7.

Dropping J7 broadens the identification to the generic UCFL205 size and other possible executions.

2-Bolt Mounting – 99 mm Hole Spacing

FAG UCFL205-J7 has:

2 mounting holes.

Each mounting hole has a diameter of:

16 mm.

The centre-to-centre mounting-hole spacing is:

J = 99 mm.

This is one of the most important dimensions when identifying an existing flange bearing unit.

A:

25 mm shaft diameter

alone does not establish mounting compatibility.

Before ordering, verify:

shaft diameter – 25 mm

housing length – 130 mm

flange width – 68 mm

mounting-hole spacing – 99 mm

and:

mounting holes – 2 x 16 mm.

FAG UCFL205-J7 Load Ratings

Basic dynamic load rating:

Cr = 14,000 N = 14 kN

Basic static load rating:

C0r = 7,800 N = 7.8 kN

Cr and C0r are standardized bearing parameters used in bearing selection and calculation.

They should not be interpreted simply as universal maximum permissible loads for the complete mounted housing unit regardless of mounting arrangement, load direction, operating speed and other application conditions.

Selection and Interchangeability

When selecting a replacement for FAG UCFL205-J7, verify:

exact designation – UCFL205-J7

shaft diameter d = 25 mm

UC205 insert bearing

FL205 flange housing

2-bolt elongated flange configuration

housing length 130 mm

flange width 68 mm

mounting-hole spacing J = 99 mm

mounting-hole diameter 16 mm

shaft-locking system

load ratings

and:

operating conditions.

The 205 size designation or 25 mm bore alone does not establish interchangeability.

The exact product described on this page is:

FAG UCFL205-J7 – complete 2-bolt flange bearing unit for a 25 mm shaft, combining a UC205 radial insert ball bearing with an FL205 cast-iron housing.

UCFL 205 J7 FAG – Is It the Same as FAG UCFL205-J7?

Yes. Search formats such as:

UCFL 205 J7 FAG

FAG UCFL 205 J7

UCFL205 J7 FAG

UCFL205-J7 FAG

and:

FAG UCFL205-J7

are common ways of searching for the same exact FAG reference.

For precise technical identification, use:

FAG UCFL205-J7.

Is UCFL205 the Same as UCFL205-J7?

UCFL205 is a general size and construction designation used across the bearing industry.

UCFL205-J7 is the specific FAG execution.

Therefore, when the exact FAG product is required, the complete reference should be retained:

FAG UCFL205-J7.

Does FAG UCFL205-J7 Fit a 25 mm Shaft?

Yes. The nominal bore diameter is:

d = 25 mm.

However, when replacing the complete unit, also verify:

130 mm housing length

68 mm flange width

99 mm mounting-hole spacing

and:

2 x 16 mm mounting holes.

Is FAG UCFL205-J7 a 2-Bolt or 4-Bolt Flange Bearing?

It is a 2-bolt flange bearing unit.

This is one of the principal differences between:

UCFL – elongated / oval 2-bolt flange housing

and:

UCF – square 4-bolt flange housing.

The two housing styles should not be treated as interchangeable merely because they use the same bearing size.

Is UCFL205-J7 a Pillow Block Bearing?

No.

FAG UCFL205-J7 is a 2-bolt flange bearing unit, not a pillow block.

A pillow block bearing unit has a different housing geometry and mounting arrangement.

Users searching for a 25mm pillow block bearing should therefore verify whether their machine actually requires a pillow-block housing or the 2-bolt flange configuration of UCFL205-J7.

FAQ

What is FAG UCFL205-J7?

FAG UCFL205-J7 is a complete 2-bolt flange bearing unit consisting of a UC205 radial insert ball bearing and an FL205 cast-iron flange housing.

What bore size does FAG UCFL205-J7 have?

The nominal bore diameter is 25 mm.

What is the mounting-hole spacing of UCFL205-J7?

The centre-to-centre distance between the two mounting holes is J = 99 mm.

Which bearing insert is used in FAG UCFL205-J7?

The unit uses a UC205 radial insert ball bearing.

Is UC205 the same product as UCFL205-J7?

No. UC205 is the insert bearing only, while UCFL205-J7 is the complete UC205 + FL205 housed bearing unit.

What is the difference between UCFL205 and UCF205?

UCFL205 uses an elongated 2-bolt flange housing, while UCF205 uses a square 4-bolt flange housing. Their mounting configurations are therefore different.

What does J7 mean in FAG UCFL205-J7?

J7 is part of the exact FAG execution designation and relates to the bearing-to-housing fit. It does not indicate shaft diameter or C3 internal clearance.

Can any UCFL205 replace FAG UCFL205-J7?

Interchangeability should not be assumed from the UCFL205 designation alone. Verify the 25 mm bore, housing dimensions, 99 mm mounting-hole spacing, 16 mm hole diameter, insert construction, shaft-locking system, load ratings and housing execution.
