FAG UC206 – Technical Characteristics

FAG UC206 Dimensions – 30x62x38.1 mm

The principal dimensions of FAG UC206 are:

d = 30 mm – bore diameter

D = 62 mm – outside diameter

B = 38.1 mm – overall width across the extended inner ring

C = 19 mm – outer ring width

The common dimensional search format is:

30x62x38.1 mm

The distinction between dimensions B and C is important. UC206 is not a conventional 30x62 mm deep groove ball bearing; its geometry is designed for use as a radial insert bearing in a compatible housing.

What Is FAG UC206?

FAG UC206 belongs to the UC radial insert ball bearing family.

Its characteristic construction includes:

30 mm cylindrical bore

spherical outer ring surface

extended inner ring

and:

shaft location by grub screws.

When installed in a compatible housing, the bearing forms part of a complete housed bearing unit.

Spherical Outer Ring Surface

The outer ring of FAG UC206 has a spherical outside surface designed to interact with a matching spherical seat in a compatible housing.

This arrangement allows the housed bearing unit to compensate for limited static misalignment resulting from mounting.

UC206 should not be confused with a conventional double row self-aligning ball bearing.

Its alignment capability comes from the interface between the:

spherical outside surface of the bearing

and:

matching housing seat.

Extended Inner Ring

A characteristic feature of the UC206 design is its extended inner ring.

For this reason, the overall bearing width:

B = 38.1 mm

is considerably greater than the outer ring width:

C = 19 mm.

Both dimensions should be checked when identifying an existing bearing or selecting a replacement.

Shaft Location by Grub Screws

FAG UC206 is secured to the shaft using grub screws, also commonly described as:

set screws.

The screws are positioned in the extended inner ring and mechanically locate the inner ring relative to the shaft.

This is an important selection parameter.

A radial insert bearing using an eccentric locking collar, adapter sleeve or another shaft-locking method should not automatically be considered interchangeable merely because the basic dimensions are similar.

What Does UC206 Mean?

UC206 identifies a widely used dimensional and constructional family of radial insert ball bearings.

The designation may be encountered in different written forms:

UC206

UC 206

or:

UC-206.

For exact product identification, the manufacturer should also be included.

The product described here is:

FAG UC206.

This distinction matters because bearings carrying the general UC206 designation from different manufacturers should not automatically be assumed to have identical detailed specifications.

FAG UC206 – 30 mm Bore

FAG UC206 has a nominal bore diameter:

d = 30 mm.

For this reason, buyers may also search for the product using phrases such as:

UC206 30mm

UC206 30 mm bearing

FAG insert bearing 30mm

or:

30mm bore insert bearing.

The bore diameter alone is not sufficient for exact product identification. The complete bearing design and dimensions must also be checked.

UC206 vs Standard 6206 Bearing

UC206 and a conventional 6206 deep groove ball bearing both have a nominal:

30 mm bore.

However, they are fundamentally different bearing designs.

FAG UC206 has:

spherical outer ring surface

extended inner ring

grub-screw shaft locking

and:

geometry intended for installation in a compatible housing.

A conventional 6206 deep groove ball bearing should therefore not be considered a replacement for UC206 simply because both products have a 30 mm bore.

UC206 Bearing vs Complete Bearing Unit

The designation:

UC206

refers to the radial insert bearing itself.

In many applications, UC206 is installed inside a separate bearing housing to form a complete housed bearing unit.

Therefore, a buyer looking for a complete unit should also verify:

housing type

housing dimensions

mounting arrangement

and:

required shaft position.

A UC206 insert bearing and a complete UC206-based housed unit are not the same product.

Selection and Interchangeability

When selecting a replacement for FAG UC206, verify:

manufacturer – FAG

bearing type – radial insert ball bearing

bore diameter d = 30 mm

outside diameter D = 62 mm

overall width B = 38.1 mm

outer ring width C = 19 mm

spherical outer ring surface

extended inner ring

grub-screw shaft locking

sealing configuration

housing compatibility

and:

required operating parameters.

Matching the nominal 30x62x38.1 mm dimensions alone does not establish full interchangeability.

UC 206 FAG – Is It the Same as FAG UC206?

The search phrases:

UC 206 FAG

FAG UC 206

UC206 FAG

and:

FAG UC206

are commonly used to find the same FAG reference.

For technical documentation and product identification, the preferred compact form is:

UC206 30x62x38.1 – What Do the Dimensions Mean?

The commonly quoted dimensions:

30x62x38.1 mm

refer to:

30 mm – bore diameter

62 mm – outside diameter

38.1 mm – overall width B across the extended inner ring.

The outer ring itself has a width:

C = 19 mm.

This distinction is particularly important when measuring an existing bearing for identification.

UC206 30mm Bearing – Is Bore Size Enough?

No.

A 30 mm bore is an important identification parameter but does not uniquely identify UC206.

Before ordering, also verify:

outside diameter

overall width

outer-ring geometry

shaft-locking method

sealing arrangement

and:

housing compatibility.

Can Another Brand of UC206 Replace FAG UC206?

The designation UC206 is used by multiple bearing manufacturers, but the designation alone should not be treated as proof of complete interchangeability.

Before replacing FAG UC206 with another manufacturer's UC206, compare the complete dimensional drawing, shaft-locking arrangement, sealing system, tolerances, load ratings and compatibility with the existing housing and operating conditions.
