Welcome to Linqing Xinshengdi Bearing Co., Ltd.
FCD6896350 Four-Row Cylindrical Roller Bearing
- Four-Row Roller Density: Distributes extreme radial crushing forces evenly across four parallel sets of cylindrical rollers.
- Low-Friction Architecture: Optimized internal geometry minimizes rolling friction, reducing heat generation even at high rolling speeds.
- Heavy-Duty Machined Cages: Equipped with robust machined brass or pin-type steel cages to maintain precise roller separation under severe operational stress.
Deep Application & Technical Narrative:
The FCD6896350 is a massive, highly specialized four-row cylindrical roller bearing engineered exclusively for the roll necks of heavy metallurgical rolling mills and steel flattening equipment. In these extreme industrial environments, bearings are subjected to unyielding, continuous radial pressure as thick metal is compressed into sheets. The four-row architecture provides the absolute maximum radial load density possible within a confined roll neck space. Even for massive industrial components like the FCD6896350, we utilize our specialized residential assembly workspace to conduct meticulous manual reviews. We physically check the cage integrity and verify the radial clearance uniformity across all four rows. This hands-on verification bypasses the oversight risks of large automated factory lines, ensuring that your heavy-industry clients receive a structural component capable of surviving the punishing forces of a continuous steel mill.
Customized B2B Supply & Packaging Solutions:
Demonstrating our capacity to supply a truly full range of bearing types—from automotive components to massive industrial mill bearings—we provide robust logistical support for the FCD6896350. These heavy-mass bearings are heavily oiled, wrapped in industrial polymer, and secured in reinforced wooden crating for safe ocean transit. We manage the complex export routing required to reach heavy industrial sectors in South America, Russia, and Africa.
Targeted Technical Clarifications (FAQ):
Q: Can this four-row bearing handle axial thrust loads in the rolling mill?
A: No. Four-row cylindrical roller bearings accommodate only pure radial loads. They must always be paired with a separate thrust bearing (like an angular contact or deep groove bearing) to manage the axial forces of the roll neck.
Q: Are the inner and outer rings interchangeable?
A: Yes, cylindrical roller bearings of this type generally feature separable components, allowing the inner ring to be heat-shrunk onto the roll neck independently from the outer ring and roller assembly.
