Tapered Roller Bearings Product Introduction

**TIMKEN Tapered Roller Bearings – Single Cones (Imperial Series 2490): Engineered for Precision and Durability**

TIMKEN tapered roller bearings are synonymous with reliability, high load capacity, and precision performance in demanding industrial and automotive applications. Among its extensive portfolio, the **TIMKEN Single Cone Tapered Roller Bearings (Imperial Series 2490)** stand out as a critical component for machinery requiring robust radial and thrust load support. Designed with exacting tolerances and superior metallurgy, these bearings excel in applications where misalignment resistance, long service life, and operational efficiency are paramount.

### **Technical Features & Design Advantages**
The **TIMKEN 2490 Series Single Cone** bearings are engineered to handle combined radial and axial loads, thanks to their precision-ground tapered rollers and raceways. Key features include:

– **Optimized Load Distribution:** The tapered geometry ensures even stress distribution across the rollers, reducing edge loading and extending bearing life.
– **High-Strength Steel Construction:** Manufactured from premium alloy steels, these cones undergo advanced heat treatment processes to enhance hardness, fatigue resistance, and durability under heavy loads.
– **Interchangeability & Precision Fit:** Designed to meet imperial (inch) dimensions, the 2490 Series cones are compatible with TIMKEN cups and assemblies, ensuring seamless integration into existing systems.
– **Enhanced Lubrication Retention:** The precision-machined surfaces and optimized roller profiles promote efficient lubricant flow, minimizing friction and heat generation.

### **Performance Benefits**
TIMKEN’s Single Cone bearings deliver unmatched performance in harsh operating conditions:
– **Superior Durability:** The hardened steel construction resists wear, spalling, and micro-fatigue, even in high-vibration environments.
– **Reduced Friction & Heat Build-Up:** Precision grinding and optimized roller alignment lower rotational resistance, improving energy efficiency.
– **Versatile Mounting Options:** Single cones allow for adjustable preload and axial clearance, making them ideal for applications requiring precise shaft positioning.

### **Typical Applications**
TIMKEN 2490 Series Single Cones are widely used in heavy-duty industrial and automotive systems, including:
– **Industrial Gearboxes & Pumps:** Supporting shafts in high-torque, low-speed, or high-speed applications.
– **Construction & Mining Equipment:** Wheel hubs, conveyor systems, and crushers where shock loads are prevalent.
– **Automotive Axles & Transmissions:** Providing reliable performance in truck differentials and drivetrains.
– **Precision Machinery:** Machine tool spindles and agricultural equipment requiring tight tolerances.

For engineers and maintenance professionals seeking a balance of strength, precision, and longevity, **TIMKEN’s 2490 Series Single Cone Tapered Roller Bearings** offer a proven solution backed by over a century of bearing innovation. Whether in extreme environments or precision assemblies, these bearings ensure optimal performance with minimal downtime.
