Different rolling mill positions require different bearing structures. TEDIN supplies standard and customized rolling mill bearings for steel mill maintenance, roll neck replacement, gearbox support and non-standard bearing projects according to bearing number, drawing, sample or working condition.
| Bearing Type | Common Use in Rolling Mills |
|---|---|
| Four-row Cylindrical Roller Bearings | Used for roll necks, work rolls and backup roll positions where high radial load capacity and stable radial support are required. |
| Four-row Tapered Roller Bearings | Commonly used in roll neck applications where combined radial and axial loads must be supported. |
| Spherical Roller Bearings | Used in heavy-duty support positions, auxiliary equipment and applications with possible shaft deflection or misalignment. |
| Thrust Roller Bearings | Applied in rolling mill equipment and drive systems where axial load support is required. |
| Backing Bearings | Used in cluster mills, Sendzimir mills and support roll systems with compact high-load bearing arrangements. |
| Custom Large-size Bearings | Supplied for non-standard replacement, equipment rebuild and large-size bearing production based on drawings or samples. |
If your bearing number is not listed, TEDIN can support equivalent replacement, old marking identification and custom rolling mill bearing production.
Key Selection Factors for Rolling Mill Bearings
Rolling mill bearing selection should consider load direction, roll neck size, speed, lubrication, contamination, fitting accuracy and maintenance conditions. These factors help determine the suitable bearing structure, clearance, tolerance and sealing arrangement.
Load Direction
Radial load, axial load, impact load and vibration should be reviewed according to the roll position and mill operating condition.
Roll Neck & Space
Roll neck diameter, installation space, housing structure and fitting dimensions affect bearing type, bore size and mounting arrangement.
Speed & Lubrication
Rolling speed, lubrication condition, grease or oil supply and heat generation should be considered for stable bearing operation.
Water & Contamination
Water spray, scale contamination, dust and cooling media may affect sealing arrangement, lubricant life and bearing maintenance interval.
Clearance & Tolerance
Bearing clearance, fitting tolerance, shaft tolerance and housing accuracy should be matched to reduce abnormal heat, vibration or early failure.
Maintenance Conditions
Maintenance interval, replacement frequency, inspection access and lubrication schedule should be considered for steel mill spare parts planning.
TEDIN can help check replacement options according to existing bearing references, old markings or equivalent bearing numbers from original equipment documentation.

Rolling Mill Bearing Quality Control and Inspection
Key manufacturing processes and inspection items are checked to support stable performance of replacement rolling mill bearings under heavy radial load, shock load and continuous steel mill operation.
Material Inspection
Bearing steel, forgings and related components are checked before machining to support stable performance in roll neck and backup roll positions.
Heat Treatment Control
Hardness, hardened layer, microstructure and dimensional stability are controlled to help improve bearing durability under heavy-duty rolling conditions.
Raceway Grinding Check
Raceways, ribs, end faces and fitting surfaces are ground and measured to support accurate load distribution and reliable mounting accuracy.
Roller Sorting
Roller diameter grouping and sorting are checked to support consistent load sharing in four-row cylindrical and tapered roller bearing designs.
Available Inspection Reports
Inspection documents can be provided according to order requirements, bearing type, bearing size and application conditions.
Report availability may vary according to bearing type, size, order quantity and specific inspection requirements.
KOCKS-Type Rod Mill Stand Bearing Replacement Case
A steel mill needed a reliable replacement bearing solution for a KOCKS-type rod mill stand housing. TEDIN supplied a custom bearing set based on the equipment structure, fitting dimensions and demanding working conditions of the rod mill stand.
This case demonstrates TEDIN’s capability to support rolling mill maintenance and equipment rebuild projects where standard bearing references are not enough and customized dimensional matching is required.
Rolling Mill Bearing Supply FAQs
Answers to common questions from steel mill maintenance teams, equipment rebuilders and industrial bearing buyers.
Can you supply rolling mill bearings according to drawings or existing bearing references?
Yes. TEDIN can support rolling mill bearing replacement according to existing bearing references, drawings, samples or key dimensions. For non-standard applications, we can review bore diameter, outside diameter, width, clearance, structure and operating conditions before quotation.
What information should we provide for a rolling mill bearing inquiry?
Please provide the bearing number, drawing, dimensions, mill stand position, roll neck size, load condition, speed, lubrication method and required quantity. Photos of the old bearing, package label or bearing marking are also helpful for replacement projects.
Which rolling mill bearing types can you supply?
We supply four-row cylindrical roller bearings, four-row tapered roller bearings, spherical roller bearings and related bearing solutions for work rolls, backup rolls, intermediate rolls and roll neck positions in steel rolling lines.
Can you support bearing replacement for old equipment or discontinued models?
Yes. For old equipment or discontinued bearing models, we can review the original bearing reference, drawing, sample or installation dimensions. If necessary, our team can help confirm the structure, clearance and key fitting dimensions before production.
Can inspection reports be provided before shipment?
Inspection documents can be provided according to order requirements, bearing size and application conditions. Available documents may include raw material certificate, heat treatment report, hardness test report, dimensional inspection report, clearance inspection report, NDT report and CMM inspection report.
What is the typical delivery time for rolling mill bearings?
Delivery time depends on bearing type, size, quantity and production schedule. Stock or standard items can usually be delivered faster, while large-size or customized rolling mill bearings require additional production, inspection and packing time.
How are large rolling mill bearings packed for export?
Bearings are protected with anti-rust treatment and packed in strong export wooden cases or industrial packaging according to bearing size and transport requirements. Marking, packing photos and shipment confirmation can be provided when required.
