3208-B-TV NKE 40x80x30.2 Double Row Angular Contact Ball Bearing

3208-B-TV NKE is a double row angular contact ball bearing with dimensions 40x80x30.2 mm. It has a 40 mm bore diameter, 80 mm outside diameter and 30.2 mm width. The bearing has an open design without seals and uses a polyamide cage. Its double row angular contact geometry enables it to support radial loads together with axial loads acting in both directions.

3208-B-TV NKE - Product Characteristics

The exact NKE designation is 3208-B-TV. The bearing belongs to the double row angular contact ball bearing family.

Its technical identification is:

3208-B-TV -> NKE -> double row angular contact ball bearing -> 40x80x30.2 mm -> open design -> polyamide cage

The two-row arrangement is an important construction feature because it provides axial load capability in both directions within a single bearing unit.

Dimensions

The verified dimensions of 3208-B-TV NKE are:

d - Bore Diameter: 40 mm
D - Outside Diameter: 80 mm
B - Width: 30.2 mm
Dimensions: 40x80x30.2 mm
Weight: 0.6 kg
EAN: 9008745137372

The exact catalog width is 30.2 mm, not 30 mm. Therefore, 40x80x30.2 mm should be used for technical identification and replacement selection.

Double Row Angular Contact Construction

3208-B-TV contains two rows of balls operating on angular contact raceways.

In an angular contact bearing, the load transmission lines between the balls and raceways are inclined relative to the radial plane. This geometry enables the bearing to carry combined loads consisting of both radial and axial components.

The two-row configuration enables axial loads to be supported in both directions, unlike an individual single row angular contact ball bearing, which primarily supports axial load in one direction.

A double row angular contact bearing can therefore provide functionality comparable to an appropriately arranged pair of single row angular contact bearings while using a single integrated bearing unit.

Load Carrying Capacity

Catalog data for the exact 3208-B-TV NKE reference specify:

Basic Dynamic Load Rating C: 46 kN
Basic Static Load Rating C0: 34.6 kN
Fatigue Load Limit: 1.6 kN

These values are bearing catalog ratings and should not be interpreted as the maximum permissible load of a complete machine assembly.

Actual bearing selection must consider the direction and magnitude of loads, operating speed, lubrication, fits, temperature and required bearing life.

Open Bearing Design

3208-B-TV NKE is an open bearing, meaning that it does not have integral rubber seals or metal shields.

This feature is important when comparing it with sealed or shielded variants from the same dimensional series. A designation containing 2RS or 2Z, for example, identifies a different closure configuration.

The open design should therefore be considered part of the product specification when selecting a replacement.

Meaning of the 3208-B-TV Designation

3208 identifies the bearing series and size within the double row angular contact ball bearing family.

TV identifies the polymer cage configuration. Available technical catalogue data specify a glass-fibre-reinforced PA66 polyamide cage guided by the rolling elements.

The B suffix is retained as an integral part of the manufacturer's exact designation. Available secondary sources provide conflicting interpretations of the precise contact angle for this exact reference, so a specific contact-angle value is not stated here without unambiguous current NKE manufacturer confirmation.

Radial and Axial Loads

The angular contact raceway geometry allows 3208-B-TV NKE to support radial and axial load components simultaneously.

Because two rows of rolling elements are arranged within the bearing, axial forces can be supported in both directions. This characteristic also gives the bearing greater ability to locate a shaft axially than a conventional single row deep groove ball bearing.

The actual permissible combined loading depends on operating conditions and should be calculated using the manufacturer's bearing selection data.

Selection and Interchangeability

A bearing should not be selected as a replacement for 3208-B-TV NKE solely because it measures 40x80x30.2 mm.

For interchangeability, verify:

• designation and bearing series
• 40 mm bore diameter
• 80 mm outside diameter
• 30.2 mm width
• double row angular contact construction
• open configuration
• cage design
• load ratings
• internal bearing specification
• required operating conditions

The official NKE/Fersa product data identify FAG 3208-BD-XL-TVH as a cross-reference. Even with a manufacturer-listed cross-reference, the complete specifications should be checked against the requirements of the existing bearing arrangement before installation.

FAQ

What are the dimensions of 3208-B-TV NKE?

The exact dimensions are 40x80x30.2 mm: d = 40 mm bore diameter, D = 80 mm outside diameter and B = 30.2 mm width.

Is the width of NKE 3208-B-TV 30 mm or 30.2 mm?

The catalog width is 30.2 mm. The 30 mm figure is a rounded value and should not replace the exact catalog dimension when identifying the bearing.

What type of bearing is 3208-B-TV NKE?

It is a double row angular contact ball bearing.

Can 3208-B-TV carry axial loads in both directions?

Yes. Its double row angular contact construction enables it to support axial loads in both directions, in addition to radial loading.

Is NKE 3208-B-TV sealed?

No. 3208-B-TV is an open bearing without integral seals or shields.

What does TV mean in 3208-B-TV?

The TV suffix identifies the polymer cage configuration. Technical catalogue data specify a glass-fibre-reinforced PA66 polyamide cage guided by the rolling elements.

What are the load ratings of NKE 3208-B-TV?

The specified basic dynamic load rating C is 46 kN, basic static load rating C0 is 34.6 kN, and fatigue load limit is 1.6 kN.

Can another brand replace NKE 3208-B-TV?

The official NKE/Fersa data identify FAG 3208-BD-XL-TVH as a cross-reference. However, dimensions alone are insufficient for replacement selection; construction, cage, internal specification, load ratings and operating requirements should also be checked.
