Four Row Tapered Roller Bearings

Four row tapered roller bearings are mainly used in rolling mill equipment, especially in backup roll and work roll positions where heavy radial loads, axial loads and impact loads may occur. Their multi-row design provides high load capacity and stable performance under demanding mill conditions.

Yes. TEDIN can review existing bearing numbers, drawings, sample photos or measured dimensions to evaluate interchangeability. For replacement projects, we can help confirm key dimensions, spacer arrangement, clearance requirements and manufacturing feasibility before production.

To support quotation or technical review, please provide as much information as possible, such as:

• Existing bearing model or part number
• Main dimensions, including bore, outside diameter and width
• Drawing, sample photos or installation position
• Rolling mill type, load, speed and lubrication conditions
• Required inspection reports or quality documents

Yes. TEDIN supports customized production based on drawings, old samples or special application requirements. Custom options may include non-standard dimensions, clearance, cage structure, spacer matching, lubrication grooves and other design details required by rolling mill applications.

Depending on project requirements, TEDIN can provide quality documents such as raw material reports, heat treatment records, dimensional inspection reports, roundness or profile inspection results, hardness reports and flaw detection reports when required.

Four row tapered roller bearings can support combined radial and axial loads, while four row cylindrical roller bearings are generally selected for very high radial load capacity. The final selection depends on the rolling mill position, load direction, mounting structure and required operating performance.
