SS-SB206 30x62x30 Stainless Steel Insert Ball Bearing

SS-SB206 30x62x30 Stainless Steel Insert Ball Bearing

SS-SB206, also designated SSSB206, is a stainless steel insert ball bearing measuring 30x62x30 mm.

It has a 30 mm bore diameter, 62 mm outside diameter and 30 mm overall width.

The bearing features a spherical outer ring surface designed to work with a suitable bearing housing. This construction allows the bearing unit to accommodate limited initial misalignment between the shaft and housing.

What Does SS-SB206 Mean?

The designation contains two important elements:

SS - Stainless Steel

SB206 - insert ball bearing series and size designation

For this version, the principal dimensions are:

30 mm - bore diameter
62 mm - outside diameter
30 mm - overall bearing width

The complete SS-SB206 designation should be retained when a stainless steel version is required.

Insert Ball Bearing Design

SS-SB206 belongs to the insert ball bearing category.

Unlike a conventional deep groove ball bearing, the outer ring has a spherical outside surface designed to fit into a correspondingly shaped bearing housing.

This allows the bearing and housing assembly to accommodate limited initial alignment differences between the shaft and housing.

SS-SB206 should therefore be identified as an insert bearing rather than a conventional 6206 deep groove ball bearing.

Spherical Outer Ring Surface

A characteristic feature of the SS-SB206 is its spherical outer ring surface.

The spherical profile works together with the corresponding seating surface of a compatible bearing housing.

This construction is one of the principal differences between an SB206 insert bearing and a conventional deep groove ball bearing with similar bore and outside diameters.

Extended Inner Ring

The SB206 design incorporates an inner ring extended on one side.

The extended section provides the geometry required for securing the bearing to the shaft.

When replacing an existing insert bearing, the inner-ring configuration and shaft-locking method should be compared with the original bearing.

Shaft Mounting

The SS-SB206 insert bearing is secured directly to the shaft using set screws in the extended inner ring.

This provides a mechanical connection between the bearing inner ring and the shaft.

The shaft diameter for this bearing is nominally:

30 mm

The shaft-locking method should be verified when selecting a replacement, as other insert-bearing series can use different mounting systems.

SS - Stainless Steel Version

The SS prefix identifies the stainless steel version.

This is an important distinction between:

SB206 - standard series designation

and

SS-SB206 / SSSB206 - stainless steel version

The SS designation should therefore be retained in the product reference whenever stainless steel construction is required.

Sealed Insert Bearing

The neutral SS-SB206 configuration is supplied as a sealed insert bearing.

Sealing on both sides helps retain lubricant inside the bearing and helps reduce the ingress of external contamination toward the rolling elements.

The exact seal material should not be assumed without documentation for the specific manufacturer or production batch.

SS-SB206 vs SB206

Both references belong to the same dimensional insert-bearing family, but the material version is important.

SS-SB206:
stainless steel version
30x62x30 mm
insert ball bearing
spherical outer ring surface
shaft locking system

SB206:
standard material version depending on manufacturer
30x62x30 mm
insert ball bearing
spherical outer ring surface

When stainless steel construction is required, the SS prefix is therefore an essential part of the identification.

SS-SB206 vs 6206 Bearing

SS-SB206 should not be confused with a standard 6206 deep groove ball bearing simply because both have a 30 mm bore and 62 mm outside diameter.

SS-SB206:
30x62x30 mm
insert ball bearing
spherical outer ring surface
extended inner ring
shaft locking system

6206:
30x62x16 mm
conventional deep groove ball bearing

These are different bearing constructions intended for different mounting arrangements.

How to Select SS-SB206

For correct identification, verify:

Designation: SS-SB206 / SSSB206
Bore Diameter: 30 mm
Outside Diameter: 62 mm
Overall Width: 30 mm
Bearing Type: Insert ball bearing
Version: Stainless steel
Outer Ring Surface: Spherical
Shaft Mounting: Set screws

Complete identification:

SS-SB206 + 30x62x30 mm + Stainless Steel + Insert Ball Bearing

Dimensions alone should not be used to confirm full interchangeability.

FAQ

What are the dimensions of SS-SB206?

The principal dimensions are 30x62x30 mm: 30 mm bore diameter, 62 mm outside diameter and 30 mm overall width.

What does SS mean in SS-SB206?

SS means Stainless Steel, identifying the stainless steel version of the SB206 insert bearing.

What type of bearing is SS-SB206?

SS-SB206 is an insert ball bearing designed to work with a compatible bearing housing.

Does SS-SB206 have a spherical outer ring?

Yes. The outside surface of the outer ring is spherical for use in a correspondingly shaped housing.

What shaft diameter is SS-SB206 designed for?

The bearing has a 30 mm bore and is designed for a nominal 30 mm shaft.

How is SS-SB206 secured to the shaft?

The bearing is secured using set screws located in the extended inner ring.

Is SS-SB206 the same as a 6206 bearing?

No. SS-SB206 is a 30x62x30 mm insert bearing with a spherical outer surface and extended inner ring. A standard 6206 is a conventional 30x62x16 mm deep groove ball bearing.

Does SS-SB206 have seals?

Yes. The neutral SS-SB206 configuration is sealed on both sides. The exact seal material depends on the specific manufacturer and should not be assumed for a no-name bearing.
