Thrust Ball Bearings

Thrust Ball Bearings - SKF, FAG, NTN, NSK, KOYO

Thrust ball bearings, also known as axial ball bearings, are designed primarily to accommodate axial loads acting along the shaft axis. Their construction is optimized for axial shaft location and differs significantly from conventional deep groove ball bearings.

At simmering.pl, we offer thrust ball bearings from manufacturers including SKF, FAG, INA, NTN, NSK, KOYO, SNR and other bearing brands. The range covers popular dimensional series and sizes for industrial machinery, gearboxes, machine tools, maintenance and MRO applications.

Thrust Ball Bearing Design

A typical single direction thrust ball bearing consists of a shaft washer, housing washer and ball and cage assembly. The raceways are designed to transmit loads acting in the axial direction.

Most standard thrust ball bearings are separable, allowing the washers and ball and cage assembly to be mounted separately. Correct alignment and mounting are important for reliable operation and bearing service life.

Single Direction and Double Direction Thrust Ball Bearings

Single direction thrust ball bearings accommodate axial loads in one direction and locate the shaft axially in one direction.

Double direction thrust ball bearings accommodate axial loads in both directions and can locate the shaft axially in both directions.

The correct design depends primarily on the direction of axial loading and the bearing arrangement within the machine.

511, 512, 513 and 514 Thrust Bearing Series

Popular single direction thrust ball bearing series include:

511 series - compact designs with relatively small cross-sections.

512 series - widely used thrust bearings for industrial and mechanical applications.

513 series - bearings with larger cross-sections and different load-carrying characteristics.

514 series - heavier cross-section designs for appropriately selected bearing arrangements.

Typical designations include 51105, 51107, 51202, 51205, 51306 and 51408.

Bearings with the same basic designation from different manufacturers may share principal dimensions, but their complete technical specifications should always be verified before replacement.

SKF Thrust Ball Bearings

SKF thrust ball bearings are an important part of this category and are available in numerous sizes and designs for industrial machinery and replacement applications.

When selecting an SKF thrust ball bearing, check the complete bearing designation together with its dimensions and catalogue specifications. Additional suffixes may identify cage design or other bearing characteristics.

The range at simmering.pl also includes FAG, NTN, NSK, KOYO thrust ball bearings and products from other recognized manufacturers.

Can Thrust Ball Bearings Carry Radial Loads?

This is one of the most important considerations when selecting this bearing type.

Standard thrust ball bearings are designed for axial loads and should not be subjected to radial loads.

If significant radial and axial loads occur simultaneously, an appropriate bearing arrangement or another bearing type designed for combined loads should be selected.

How to Select a Thrust Ball Bearing

Important selection parameters include:

complete manufacturer designation
bore diameter d
outside diameter D
bearing height T
axial load direction
dynamic load rating
static load rating
permissible speed
cage design
lubrication
operating temperature
mounting conditions

Matching dimensions alone do not necessarily guarantee complete bearing interchangeability.

Applications of Thrust Ball Bearings

Thrust ball bearings are used in appropriately designed:

industrial machinery
machine tools
gearboxes
screw mechanisms
drive systems
conveying equipment
agricultural machinery
mechanical equipment

Their primary function is to support and control axial loads within the bearing arrangement.

Thrust Ball Bearings for Industry and MRO

Our range is suitable for industrial plants, machine manufacturers, maintenance departments, MRO organizations, repair workshops and technical service companies.

A broad selection of manufacturers, dimensional series and sizes helps users identify bearings both for existing machine repairs and new mechanical designs.

FAQ - Thrust Ball Bearings

What is a thrust ball bearing?
A thrust ball bearing is a rolling bearing designed primarily to accommodate loads acting parallel to the shaft axis.

Are thrust ball bearings and axial ball bearings the same?
Yes. "Axial ball bearing" is commonly used as an alternative term, while thrust ball bearing is the standard English technical term widely used by major bearing manufacturers.

Can a thrust ball bearing carry radial loads?
Standard thrust ball bearings are not designed to accommodate radial loads. They are intended primarily for axial loading.

What is the difference between single and double direction thrust ball bearings?
Single direction bearings accommodate axial load in one direction. Double direction bearings can accommodate axial loads in both directions.

What are the most common thrust ball bearing series?
Popular single direction series include 511, 512, 513 and 514.

How do I select a thrust bearing by dimensions?
Check the bore diameter d, outside diameter D and total height T, then verify the complete designation, load ratings, speed limits and design.

Do you offer SKF thrust ball bearings?
Yes. The range includes SKF thrust ball bearings, as well as FAG, NTN, NSK, KOYO and other manufacturers.

Are thrust bearings from different manufacturers interchangeable?
Bearings may have equivalent principal dimensions, but load ratings, cage designs, speed limits and other specifications should be compared before replacement.
