LM272235/10 Single Row Tapered Roller Bearing 457.2x615.95x85.725mm Heavy Duty Inch Bearing

1. Product Overview

LM272235/10 inch series single row tapered roller bearing, cone LM272235 + cup LM272210, dimension 457.2×615.95×85.725mm.

Code Definition

• LM272235: Inner cone assembly with stamped steel cage and tapered rollers
• LM272210: Single outer cup ring

Separable cone & cup structure for easy independent installation and disassembly. Optimized 12.5° contact angle supports heavy combined radial and single-direction axial load. High-density tapered rollers deliver outstanding load capacity, stable low-friction rotation under heavy vibration and shock loads. Widely used on mining mills, heavy metallurgical rollers, large industrial gearboxes and heavy haul equipment.

2. Technical Specifications

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

3. Core Advantages

1. Separable cone and cup design simplifies field assembly and maintenance
2. Large contact angle bears heavy radial and unidirectional axial combined loads
3. Reinforced stamped steel cage stable under continuous heavy shock and vibration
4. High hardness mirror-finish rollers reduce friction and extend service life
5. Ultra high static load rating adapts static heavy preload working conditions
6. Standard inch-metric dual size for direct interchange replacement
7. Optimized internal geometry lowers edge stress and prevents raceway spalling
8. Customizable precision grade, extreme pressure grease and laser marking
