NTN 33205 Metric Single Row Tapered Roller Bearing 25x52x22mm

The NTN 33205 is a metric single-row tapered roller bearing designed for applications requiring high radial and axial load capacity. This bearing utilizes conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, with the rollers guided by contact between the large end of the roller and a rib on the inner ring. This design allows the bearing to accommodate combined loads efficiently.

Key Specifications:

• Inside Diameter (Bore): 25mm
• Outside Diameter: 52mm
• Combined Width: 22mm
• Basic Dynamic Load Rating: 47.1 kN
• Basic Static Load Rating: 55.8 kN
• Weight: 0.228 kg (approximately 0.5 lbs)
• Material: Case carburized steel
• Temperature Range: -40°C to +120°C

Performance Specifications:

• Grease Lubrication Speed Limit: 8,300 rpm
• Oil Lubrication Speed Limit: 11,000 rpm
• Tolerance Class: P0/PN2 / ABEC 1
• Cage Type: Sheet steel cage

This bearing features an open enclosure design and can be disassembled into the cone assembly (inner ring, rollers, and cage) and cup (outer ring) for easy maintenance and installation. The tapered design provides excellent resistance to both radial and unidirectional axial loads, making it ideal for automotive, industrial machinery, and heavy equipment applications.
