81107 TVPB NKE 35x52x12 mm

81107 TVPB NKE 35x52x12 mm - Single Direction Cylindrical Roller Thrust Bearing

81107 TVPB NKE 35x52x12 mm is a single direction cylindrical roller thrust bearing manufactured by the Austrian bearing brand NKE Austria GmbH. It belongs to the 811 series and is designed to accommodate axial loads in one direction. The bearing consists of cylindrical rollers, a TVPB polyamide cage, and thrust washers. Its nominal dimensions are 35 mm bore diameter, 52 mm outside diameter, and 12 mm overall height. The TVPB suffix identifies the cage design.

Technical Specifications - 81107 TVPB NKE

The 81107 TVPB NKE is a thrust bearing designed to transmit forces acting along the shaft axis. It does not provide radial shaft support and must not be used as a substitute for a radial bearing.

The basic dynamic load rating, basic static load rating, limiting speed, bearing mass, and precision class are not listed here because their exact values require verification against the current NKE documentation for this specific execution.

Technical values from bearings manufactured by other brands should not be assigned to the NKE product without confirmation.

What Does 81107 TVPB NKE Mean?

The designation identifies the bearing series, dimensional size, cage execution, and manufacturer.

• 811 - Single direction cylindrical roller thrust bearing series.

• 07 - Bearing size code corresponding to a nominal bore diameter of 35 mm.

• TVPB - Polyamide cage execution.

• NKE - Austrian bearing brand NKE Austria GmbH.

The TVPB suffix is an important part of the product identification. It should be retained when ordering or comparing bearing variants.

The designation TVPB does not specify a lubricant type, increased internal clearance, or additional sealing arrangement.

TVPB Cage - Construction and Function

The cage maintains the cylindrical rollers in their correct positions and provides consistent spacing between adjacent rolling elements.

The TVPB execution uses a polyamide cage. Its material properties must be considered when evaluating operating temperature and lubricant compatibility.

The exact operating limitations should be determined using the manufacturer's documentation for the specific NKE bearing execution.

Construction and Operating Principle

The NKE 81107 TVPB is a cylindrical roller thrust bearing consisting of three main components:

• Shaft washer - The raceway washer associated with the rotating shaft.

• Housing washer - The raceway washer supported by the housing.

• Cylindrical roller and cage assembly - The rolling elements maintained in position by the TVPB cage.

The cylindrical rollers operate between the flat raceways of the thrust washers, transmitting axial forces through the bearing assembly.

Unlike thrust ball bearings, cylindrical roller thrust bearings use line contact between the rolling elements and raceways.

This construction provides axial stiffness and supports axial loads within a compact overall bearing height.

Load Direction and Bearing Function

The 81107 TVPB NKE is a single direction thrust bearing.

It is designed to accommodate axial loads acting in one direction, according to the bearing arrangement and installation orientation.

It is not intended for:

• Independent accommodation of radial loads.

• Axial location under alternating loads in both directions.

• Compensation for significant misalignment between supporting components.

If the application requires axial load support in both directions, a suitable double direction bearing arrangement or an appropriately designed pair of single direction thrust bearings must be considered.

81107 TVPB NKE vs K81107 - Construction Differences

When identifying a replacement bearing, it is important to distinguish between a complete cylindrical roller thrust bearing and a cylindrical roller and cage assembly.

81107 and K81107 do not identify identical products or identical scopes of supply.

The K prefix identifies a cylindrical roller and cage assembly without the associated raceway washers.

Before ordering, verify whether the application requires a complete thrust bearing or only the rolling element assembly.

81107 TVPB NKE vs 51107 - Technical Comparison

The 81107 and 51107 belong to different thrust bearing families, even though their basic nominal dimensions are identical.

The 81107 uses cylindrical rollers, while the 51107 uses balls. This difference affects load-carrying characteristics, axial stiffness, and permissible operating conditions.

Identical nominal dimensions of 35x52x12 mm do not guarantee interchangeability.

Before replacing one bearing type with another, verify axial load requirements, rotational speed, mounting conditions, and the technical specifications of both designs.

Alternative Designations and Reference Numbers

The NKE 81107 TVPB may be encountered under the following designation formats:

• 81107 TVPB NKE

• NKE 81107 TVPB

• 81107-TVPB NKE

• NKE 81107-TVPB

• 81107TVPB NKE

The basic designation 81107 also appears in the catalogs of other bearing manufacturers.

However, bearings sharing the 81107 designation should not automatically be considered identical.

Different executions may vary in cage material, load ratings, permissible operating speed, manufacturing tolerances, and other technical characteristics.

A replacement should be selected using complete technical specifications rather than the basic series designation alone.

Bearing Selection and Interchangeability

Before purchasing the 81107 TVPB NKE, verify the following characteristics:

• Complete bearing designation 81107 TVPB NKE.

• Nominal dimensions 35x52x12 mm.

• Single direction thrust bearing construction.

• TVPB cage execution.

• Complete bearing assembly with thrust washers.

• Magnitude and direction of axial loads.

• Required dynamic and static load ratings.

• Rotational speed.

• Operating temperature.

• Lubricant type and lubrication method.

• Accuracy of supporting surfaces.

• Shaft washer and housing washer fits.

• Radial shaft guidance requirements.

When replacing an existing bearing, the manufacturer's designation and the operating conditions of the complete bearing arrangement must be considered.

A cylindrical roller thrust bearing should not be replaced by a thrust ball bearing solely because the nominal dimensions match.

Identical dimensions do not necessarily indicate complete technical interchangeability.

Typical Applications of Cylindrical Roller Thrust Bearings

Bearings in the 811 series are designed for mechanical assemblies requiring axial load support.

Typical applications associated with this bearing construction include:

• Screw mechanisms transmitting axial forces.

• Industrial axial loading assemblies.

• Mechanical pressing and clamping mechanisms.

• Linear feed and adjustment systems.

• Compact bearing arrangements requiring axial support.

These are general applications associated with single direction cylindrical roller thrust bearings, not verified OEM applications for the specific NKE 81107 TVPB product.

Suitability for a particular machine must be determined from axial load calculations, rotational speed, required stiffness, and operating conditions.

Installation and Maintenance

Preparation Before Installation

Before installation, inspect the bearing components and supporting surfaces for cleanliness, dimensional accuracy, and mechanical damage.

The surfaces supporting the thrust washers should provide uniform axial load distribution.

Contamination, deformation, or unsuitable supporting surfaces may adversely affect bearing performance.

Correct Installation

Install the shaft washer and housing washer according to their intended functions and the requirements of the bearing arrangement.

Do not apply excessive mounting forces through the cylindrical rollers in a manner that could damage the rolling elements or raceways.

Avoid washer misalignment, which may cause uneven loading of the rolling elements.

The complete assembly must also provide suitable radial guidance for the shaft.

Lubrication

The 81107 TVPB NKE requires appropriate lubrication during operation.

Lubricant selection should consider axial load, rotational speed, operating temperature, and environmental conditions.

For a bearing with a polyamide cage, lubricant compatibility with the cage material should also be verified.

The appropriate lubrication method and relubrication intervals depend on the machine design and operating conditions.

Storage

Store the bearing in a clean, dry environment protected from moisture, dust, and mechanical damage.

Where possible, retain the bearing in its protective packaging until installation.
