size：205x485x117.5mm 30641 Roller bearing supply

30641 (formerly 7841) is a single-row tapered roller bearing (dimensions: (205*85*117.5) mm). The biggest advantage of this type of bearing is its ability to simultaneously withstand large radial loads and unidirectional axial loads, and it possesses the following core advantages: High load capacity: The line-contact roller design increases the bearing's bearing area, giving it extremely high radial and axial load capacity, suitable for heavy-duty applications. Excellent rigidity: By installing in pairs and applying preload, the rigidity of the support system can be significantly improved, reducing clearance during operation. Separable design: The inner ring (including the rollers and cage assembly) can be completely separated from the outer ring, greatly facilitating installation, disassembly, and subsequent maintenance. Low friction and low noise: Optimized roller end and flange structure contribute to the formation of a lubricating oil film, reducing friction and temperature rise during operation, thereby reducing wear and noise. High versatility: Widely used in mining machinery, metallurgical rolling mills, construction machinery, speed reducers, and various heavy-duty transmission devices.

Product Description

The advantages of tapered roller bearings include high load capacity (capable of withstanding heavy combined radial and axial loads), high precision and rigidity, excellent durability and long life, adjustable clearance, low friction and heat generation, and adaptability to high operating temperatures. Their tapered roller and raceway design effectively distributes loads, making them suitable for heavy-duty industrial machinery with high precision requirements.
