Overview
The Timken 21158-0862 tapered roller bearing is a high-precision component engineered for industrial automation, power transmission, and heavy machinery applications. Tapered roller bearings are specifically designed to handle combined radial and axial (thrust) loads, making them ideal for critical rotating equipment where both load types are present. This unit arrives in new, uninstalled condition, ready for immediate deployment in manufacturing, material handling, and industrial motion control systems.
Key Features
- Tapered roller design optimizes load distribution across radial and axial directions
- Precision-engineered for low friction and extended service life
- Compatible with standard industrial mounting configurations
- Sealed against contaminants to enhance reliability in harsh environments
- Backed by Timken’s century of bearing innovation and engineering expertise
Technical Specifications
Consult Timken’s official technical documentation and the bearing’s dimension catalog for exact bore, outer diameter, width, load ratings, and clearance specifications. The 21158-0862 designation follows Timken’s standard nomenclature for tapered roller bearing families.
Typical Applications
- Automotive axles, gearboxes, and differentials
- Industrial machinery spindles and rotating shafts
- Heavy-duty transmission and power transmission systems
- Material handling equipment and conveyor systems
- Machine tool applications requiring high rotational precision
- Wheel hub assemblies in mobile equipment
Compatibility & Replacements
Compatible With
- Standard industrial mounting housings designed for tapered roller bearing cups and cones
- Lubrication systems using standard mineral or synthetic greases
- Equipment specifying ISO tapered roller bearing standards
Replaces / Drop-In Replacement For
Verify part interchangeability with your original equipment documentation or system integrator before ordering. Tapered roller bearing cones and cups must match cup and cone part numbers for proper assembly and performance. Do not assume cross-compatibility based on bearing class alone.
Works With
- Bower, Tyson, and Hyatt tapered roller bearing families (same bearing numbering system)
- Standard preload and clearance adjustment procedures for tapered bearing pairs
- Condition monitoring and vibration analysis tools for bearing health assessment
