FAG UCFL206-J7 30 mm 2-Bolt Flange Bearing Unit

FAG UCFL206-J7 is a complete 2-bolt flange bearing unit designed for a 30 mm shaft. The assembly combines a UC206 radial insert ball bearing with an FL206 cast-iron flange housing. Its principal mounting dimensions are 148x80 mm, with J = 117 mm mounting-hole spacing and two 16 mm mounting holes.

Exact product identification:

FAG + UCFL206-J7 + UCFL 206 J7 + UC206 + FL206 + 30 mm bore + 148x80 mm flange + 117 mm bolt spacing + 2-bolt flange bearing unit

FAG UCFL206-J7 – Technical Characteristics

What Is FAG UCFL206-J7?

FAG UCFL206-J7 is a complete housed bearing unit, not a standalone UC206 bearing.

The assembly consists of:

UC206 – radial insert ball bearing

and:

FL206 – 2-bolt flange housing.

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

30 mm shaft.

For correct identification, distinguish between:

UC206 = insert bearing only

FL206 = flange housing

UCFL206-J7 = complete FAG flange bearing unit.

FAG UCFL206-J7 Dimensions

The key mounting dimensions are:

d = 30 mm – bearing bore / nominal shaft diameter

H = 148 mm – flange height

L = 80 mm – flange width

J = 117 mm – mounting-hole centre spacing

N = 16 mm – mounting-hole diameter

U = 40.2 mm – overall axial dimension

Number of mounting holes:

2

For a complete flange bearing unit, a simple three-dimension description does not provide enough mounting information.

A more useful identification is:

30 mm bore + 148x80 mm flange + 117 mm bolt spacing + 2 x 16 mm mounting holes.

FL206 2-Bolt Flange Housing

FAG UCFL206-J7 uses an FL206 cast-iron flange housing.

It has an elongated 2-bolt configuration with mounting points located on opposite sides of the bearing axis.

The:

148x80 mm flange dimensions

and:

117 mm mounting-hole spacing

are key parameters when identifying the unit.

The FL206 housing configuration is fundamentally different from a square four-bolt F206 housing.

UC206 Radial Insert Ball Bearing

The bearing insert used in FAG UCFL206-J7 is:

UC206.

Its nominal bore diameter is:

30 mm.

UC206 belongs to the radial insert ball bearing family and is designed to operate in a compatible housing.

The spherical outside surface of the insert 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 UC206 insert is secured to the shaft using set screws in the extended inner ring.

Common English terminology includes:

set screw locking

set screws

grub screw locking

and:

grub screws.

The shaft-locking system is an important selection parameter.

Another 30 mm flange bearing unit should not automatically be considered interchangeable if it uses a different shaft-location method.

FAG UCFL206-J7 vs UCF206-J7

These are different bearing-unit configurations.

UCFL206-J7 uses an:

FL206 elongated 2-bolt flange housing.

By contrast:

UCF206-J7

uses an:

F206 square 4-bolt flange housing.

Therefore:

UCFL206 ≠ UCF206.

Both units may use a UC206 insert and have a 30 mm bore, but their housing geometry and mounting-hole arrangements are different.

FAG UCFL206-J7 vs UC206

These references also identify different products.

FAG UC206

is the radial insert ball bearing itself.

FAG UCFL206-J7

is the complete assembly:

UC206 insert + FL206 flange housing.

If only the insert bearing requires replacement, UC206 is the relevant reference.

If the complete 2-bolt flange assembly is required, the relevant product is:

FAG UCFL206-J7.

What Does J7 Mean in FAG UCFL206-J7?

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

It should not be interpreted as:

shaft diameter

C3 radial internal clearance

or:

bearing precision class.

When the exact FAG product is required, retain the complete designation:

FAG UCFL206-J7.

Removing the J7 suffix broadens the identification to the generic UCFL206 size and potentially other executions.

FAG UCFL206-J7 Mounting-Hole Spacing – 117 mm

The unit has:

2 mounting holes.

Each mounting hole has a diameter of:

16 mm.

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

J = 117 mm.

This is one of the most important dimensions when identifying an existing UCFL206 flange bearing.

Before ordering, verify:

shaft diameter – 30 mm

flange height – 148 mm

flange width – 80 mm

mounting-hole spacing – 117 mm

and:

mounting-hole diameter – 16 mm.

A 30 mm shaft diameter alone does not establish mounting compatibility.

FAG UCFL206-J7 Load Ratings

Basic dynamic load rating:

Cr = 19,500 N = 19.5 kN

Basic static load rating:

C0r = 11,300 N = 11.3 kN

Fatigue load limit:

Cur = 480 N = 0.48 kN

These are standardized bearing parameters used in bearing selection and calculation.

Cr should not be interpreted as a universal maximum permissible load for the complete bearing unit regardless of mounting, load direction, required bearing life and operating conditions.

Selection and Interchangeability

When selecting a replacement for FAG UCFL206-J7, verify:

exact designation – UCFL206-J7

bore diameter d = 30 mm

UC206 insert bearing

FL206 housing type

2-bolt flange geometry

flange height H = 148 mm

flange width L = 80 mm

mounting-hole spacing J = 117 mm

mounting-hole diameter 16 mm

shaft-locking system

bearing load ratings

and:

operating conditions.

The 206 size designation, a 30 mm bore or a visually similar housing does not by itself establish full interchangeability.

UCFL 206 J7 FAG – Is It the Same as FAG UCFL206-J7?

Yes. Search formats such as:

UCFL 206 J7 FAG

FAG UCFL 206 J7

UCFL206 J7 FAG

UCFL206-J7 FAG

and:

FAG UCFL206-J7

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

For precise technical identification, use:

FAG UCFL206-J7.

Is UCFL206 the Same as UCFL206-J7?

UCFL206 is a general size and construction designation used across the bearing industry.

UCFL206-J7 is the specific FAG execution.

Therefore, when the exact FAG product is required, retain the complete reference:

FAG UCFL206-J7.

Does FAG UCFL206-J7 Fit a 30 mm Shaft?

Yes. The nominal bore diameter is:

d = 30 mm.

However, when replacing the complete unit, also verify:

148 mm flange height

80 mm flange width

117 mm mounting-hole spacing

and:

2 x 16 mm mounting holes.

Is UCFL206-J7 a 2-Bolt or 4-Bolt Flange Bearing?

FAG UCFL206-J7 is a 2-bolt flange bearing unit.

For comparison:

UCFL206 = FL206 elongated 2-bolt flange housing

UCF206 = F206 square 4-bolt flange housing.

These housing types should not be treated as interchangeable.

Is UCFL206-J7 a Pillow Block Bearing?

No.

FAG UCFL206-J7 is a 2-bolt flange bearing unit, not a pillow block bearing unit.

Pillow block housings use a different mounting geometry. This distinction matters when searching for a 30mm housed bearing, because both pillow block and flange units may use a 30 mm insert but are mounted differently.
