72 Series Angular Contact Ball Bearings
Medium-section angular contact bearings for applications that need higher axial load capacity and rigid shaft support, including pumps, gearboxes, compressors, and industrial machinery.
What Are 72 Series Angular Contact Ball Bearings?
72 series angular contact ball bearings are medium-section bearings used where a shaft needs both radial support and axial thrust control. Compared with lighter series, the 72 series offers a larger bearing section and higher load capacity.
They are commonly selected for gearboxes, pumps, compressors, machine tools, and other rotating equipment where rigidity matters. TEDIN supplies 72 series bearings as single bearings or matched sets, with arrangement options such as DB, DF, DT, TBT, TFT, and TT.
This series is part of our angular contact ball bearings range. For applications with tighter running requirements, our quality control process helps verify dimensions, noise, vibration, and rotational accuracy before shipment.
Where the 72 Series Fits
- Medium-section design: A larger section than light-series bearings, useful when load capacity and shaft support need to be increased.
- Good axial load capacity: Suitable for bearing positions that carry thrust loads in addition to radial loads.
- Matched set options: Available in common paired or grouped arrangements, depending on preload, stiffness, and load direction.
- Broad industrial use: Often used in pumps, gearboxes, compressors, machine tools, and general industrial shaft systems.
72 Series Bearing Structure and Contact
Angle Options
72 series angular contact ball bearings use an asymmetric raceway design for combined radial and axial loads. They provide firm shaft support and stable running performance in demanding rotating equipment.
Designed for Combined Radial and Axial Loads
The internal geometry of 72 series angular contact ball bearings transfers load through a defined contact angle. This helps the bearing handle radial load and axial thrust in the same bearing position.
High-speed operation
A good option when speed is the main priority and axial load is relatively light.
Balanced load support
A practical choice for applications that need a balance of speed, rigidity, and axial support.
Higher axial capacity
Used where the bearing position needs stronger thrust support and higher axial load capacity.
Selection tip: Use a smaller contact angle for higher speed. Use a larger contact angle when axial load is higher. For matched bearing sets, check the contact angle, preload, arrangement, load direction, and shaft rigidity before selection.
Matched Bearing Arrangements for 72 Series Angular Contact Ball Bearings
72 series angular contact ball bearings are supplied as single bearings or matched bearing sets. DB, DF, DT, TBT, TFT, and TT arrangements are used to set preload, improve axial rigidity, and control thrust load direction in precision machinery, pumps, gearboxes, compressors, and spindle systems.
| Arrangement | Set Type | Load Direction | Main Benefit | Typical Applications |
|---|---|---|---|---|
| DB | Back-to-back duplex | Axial load in both directions | High moment rigidity and firm shaft support | Gearboxes, pump shafts, precision rotating shafts |
| DF | Face-to-face duplex | Axial load in both directions | Better tolerance for slight shaft or housing misalignment | General machinery, supported shaft systems, reducers |
| DT | Tandem duplex | Axial load mainly in one direction | Higher thrust capacity in one primary direction | Thrust-loaded shafts, pumps, compressors |
| TBT | Triplex combination | Combined axial load support | Higher rigidity with increased thrust capacity | Heavy-duty precision machinery and spindle systems |
| TFT | Triplex combination | Combined axial load support | Balanced load distribution and controlled preload | Precision equipment requiring stable rotation |
| TT | Tandem triplex | Axial load mainly in one direction | Maximum axial capacity in one load direction | High-thrust applications and heavy-duty shaft systems |

Preload Control
Matched 72 series bearing sets can be supplied with light, medium, or heavy preload. Preload affects running accuracy, heat generation, and axial stiffness.
Axial Rigidity
Duplex and triplex arrangements increase shaft rigidity when radial load and axial thrust act at the same bearing position.
Custom Matched Sets
Contact angle, cage type, clearance, preload, and arrangement can be selected by operating speed and load direction. See our bearing quality control process for inspection details.
