32930 Single Row Tapered Roller Bearing Separable Cone & Cup 150x210x38mm Excavator Heavy Construction Equipment

The 32930 single row tapered roller bearing consists of separable inner cone roller assembly and outer cup. It can bear combined heavy radial and one-way axial loads at the same time, with optimized crowned roller design to reduce edge stress and running heat. It features high rigidity and impact resistance, widely used in excavator wheel hubs, heavy truck axles, engineering machinery transmission and mining auxiliary equipment.

• Separable cone and cup design for easy independent installation, disassembly and clearance adjustment
• Crowned tapered rollers evenly distribute load, lower friction and extend service life under impact
• Large contact angle provides outstanding composite radial and unidirectional axial load capacity
• Standard universal metric size fully interchangeable for engineering and vehicle equipment
• High-hardness quenched steel maintains stable performance under dusty heavy vibration working conditions
• Custom precision grades and anti-rust surface treatment are available on demand

This tapered roller bearing is widely applied in:

• Excavator, loader and heavy engineering vehicle wheel hub assemblies
• Heavy truck, semi-trailer drive axle and differential transmission parts
• Mining auxiliary machinery, agricultural large vehicle rotary components
• General heavy-duty equipment requiring simultaneous radial and axial load support
