Matched Tapered Roller Bearing Sets
Matched tapered roller bearing sets use two or more single row tapered roller bearings with spacer rings. They are supplied as ready-to-mount sets for face-to-face, back-to-back or tandem arrangements where clearance, preload and assembly width need to be controlled.
Spacer Matched Assembly
Inner and outer spacer rings help control axial clearance, preload and total set width.
Single Row Bearings Matched with Spacer Rings
Matched tapered roller bearing sets are assembled from single row tapered roller bearings. Spacer rings help define the set width, clearance or preload before mounting.
Single Row Bearings
Two or more bearings supplied as one matched set.
Spacer Rings
Inner and outer spacers define bearing ring position.
Controlled Setting
Clearance or preload is adjusted by the matched set design.
DF / DB / DT
Available for face-to-face, back-to-back and tandem layouts.
Note: this page covers matched single row bearing sets, not TDO or TDI integrated double row bearings.
DF, DB and DT Matched Bearing Sets
Matched tapered roller bearing sets are supplied in face-to-face, back-to-back or tandem arrangements to suit axial load direction, shaft rigidity and mounting space requirements.
Face-to-Face
Suitable for bearing pairs that need axial location in both directions while allowing a limited amount of mounting misalignment.
Back-to-Back
Used for rigid shaft supports where higher moment stiffness, stable positioning and axial load capacity in both directions are required.
Tandem
Used when two or more bearings are required to share axial load in the same direction.
Custom Matching Based on Your Operating Conditions
For matched tapered roller bearing sets, the correct arrangement and spacer design should be selected according to load direction, mounting space and required axial setting.
From Bearing Pair to Ready-to-Mount Set
TEDIN can supply matched single row tapered roller bearings with spacer rings prepared for the required clearance, preload or assembly width.
- Arrangement review: DF, DB or DT layout based on shaft support and axial load direction.
- Spacer matching: inner and outer spacer rings prepared to control the final bearing setting.
- Application fit: suitable for gearboxes, rolling mills, heavy machinery and custom bearing positions.

Inquiry tip: drawings, existing bearing numbers, target clearance or preload values can help us review the matched set more efficiently.
Where Matched Tapered Roller Bearing Sets Are Used
Matched single row tapered roller bearing sets are used in bearing positions where axial setting, load sharing and shaft support rigidity must be controlled during assembly.
Industrial Gearboxes
Used for gearbox shafts requiring controlled axial clearance, preload or stable bearing positioning under combined loads.
Rolling Mills
Suitable for mill equipment where heavy radial loads, axial loads and rigid shaft support are required.
Mining Equipment
Applied in crushers, conveyors and heavy-duty rotating equipment operating under shock load and harsh conditions.
Heavy Machinery
Used in large shafts, transmission units and custom bearing housings where matched mounting dimensions are important.
Marine & Offshore
Used in drive systems and mechanical assemblies where reliable axial support and controlled bearing setting are required.
Industrial Drives
Suitable for drive units, reducers and rotating machinery using DF, DB or DT matched bearing arrangements.
DF, DB and DT arrangements for different load directions and shaft support requirements.
Information Needed for Matched Set Inquiry
To review a matched tapered roller bearing set, please provide the bearing number, arrangement type, required setting and application details.
Required Information
The following information helps us review the matched set structure, spacer design and quotation more efficiently.
Bearing Number or Drawing
Original bearing number, drawing, sample details or target dimensions.
Arrangement Type
DF, DB, DT or custom matched layout according to your shaft design.
Required Setting
Target axial clearance, preload value or final assembly width.
Load Direction
Radial load, axial load direction and any impact or reversing load.
Mounting Dimensions
Shaft, housing, spacer dimensions and available installation space.
Application Equipment
Gearbox, rolling mill, crusher, drive unit or other equipment details.
Tip: if the original bearing set is already in use, photos of the bearing, spacers and markings can also help identify the matched set.
FAQ About Matched Tapered Roller Bearing Sets
Answers to common questions about matched single row tapered roller bearings, spacer rings, axial setting and bearing arrangements.
What is a matched tapered roller bearing set?
It is a bearing set assembled from single row tapered roller bearings with spacer rings or controlled mounting dimensions to achieve a required axial clearance, preload or set width.
Is it the same as TDO or TDI double row bearings?
No. This page focuses on matched sets made from separate single row bearings and spacers. It does not refer to integrated TDO double row tapered roller bearings or TDI double row tapered roller bearings.
What is the difference between DF and DB arrangements?
DF is a face-to-face arrangement and is often used where alignment tolerance is important. DB is a back-to-back arrangement and is commonly selected for higher moment rigidity and stable shaft support.
When should DT arrangement be selected?
DT, or tandem arrangement, is used when the bearing position must carry higher axial load mainly in one direction. It is usually reviewed according to the load direction and shaft design.
Can matched sets be supplied with preload?
Yes. Depending on the application, matched tapered roller bearing sets can be prepared for required preload, axial clearance or final assembly width. Drawings or target values are helpful for review.
What information is needed for quotation?
Please provide the bearing number, arrangement type, required clearance or preload, spacer dimensions, application equipment and drawings if available.
Need a Matched Tapered Roller Bearing Set for Your Assembly?
Send us your bearing number, existing spacer dimensions, arrangement type or assembly drawing. TEDIN can review the required DF, DB or DT matched set, axial clearance, preload and overall mounting width before quotation.
Replacement samples, existing bearing codes, spacer drawings and custom matched tapered roller bearing inquiries are welcome.
