ARB Tapered Roller Bearings Guide
Product Description
The ARB 148TQITS707 four-row tapered roller bearing consists of a central double cone, two single cones, four identical single cups, and three cup spacers. Its tapered bore is designed for an interference fit on a matching tapered roll neck, preventing the cones from turning relative to the journal and providing secure mounting under heavy rolling loads. Hydraulic oil grooves and passages in the roll neck allow the cones to expand during removal, simplifying bearing dismounting. This design provides high radial load capacity, bidirectional axial support, and reliable roll neck stability, making it suitable for heavy-duty rolling mill applications in steel, aluminum, and other metal processing industries.
