LM869448/10 Single Row Inch Tapered Roller Bearing 431.8x571.5x74.612mm Heavy

LM869448/10 inch single row tapered roller bearing, separable cone LM869448 + cup LM869410, dimension 431.8×571.5×74.612mm.

Code Definition

• LM869448: Inner cone assembly with stamped steel cage and tapered rollers
• LM869410: Outer single cup ring

Split cone and cup design enables separate installation and disassembly. 20° contact angle bears heavy mixed radial and unidirectional axial loads. High-density tapered rollers deliver stable performance under continuous shock and vibration. Open structure fits heavy low-speed equipment, widely applied in mining grinding mills, metallurgical transport rollers, large heavy-duty gearboxes and heavy haul machinery.

Installation drawings and heavy vibration durability test reports available on request.

1. Separable cone & cup structure simplifies on-site assembly and maintenance
2. 20° large contact angle carries heavy radial plus unidirectional axial combined loads
3. Reinforced stamped steel cage resists long-term heavy shock and vibration
4. Mirror polished tapered rollers reduce friction and extend service life
5. High static load rating adapts static heavy preload working conditions
6. Standard inch-metric dual dimension for direct interchange replacement
7. Optimized internal geometry lowers edge stress to avoid raceway spalling
8. Customizable precision grade, extreme pressure grease and outer ring laser marking
