Tapered Roller Bearings – 2TS-IM (Matched Bearing Assembly, Indirect Mount)

Tapered Roller Bearings Product Introduction

**TIMKEN Tapered Roller Bearings: Engineered for Precision and Durability in Demanding Applications**

TIMKEN’s **2TS and 2TS IM Matched Tapered Roller Bearing Assemblies** represent the pinnacle of performance and reliability in mechanical power transmission systems. Designed to handle combined radial and thrust loads with exceptional efficiency, these bearings are engineered for applications requiring precise alignment, high load capacity, and long service life. Whether in heavy-duty industrial machinery, automotive systems, or precision equipment, TIMKEN’s tapered roller bearings deliver unmatched durability and performance under the most demanding conditions.

### **Technical Features & Design Advantages**

The **2TS Series** consists of pre-matched bearing assemblies, comprising two single-row tapered roller bearings mounted in a direct configuration. This design ensures optimal load distribution, reducing stress concentrations and extending bearing life. Key features include:

– **Optimized Contact Geometry:** Precision-ground rollers and raceways minimize friction while maximizing load-carrying capacity.
– **Premium Steel Construction:** Manufactured from high-quality, clean steel for superior strength and fatigue resistance.
– **Precision Alignment:** Matched sets ensure consistent performance, reducing the risk of misalignment-induced wear.
– **Enhanced Lubrication Retention:** Advanced cage designs and sealing options improve grease retention and contamination resistance.

The **2TS IM (Indirect Mount) Series** offers a specialized configuration where bearings are mounted in an opposed (indirect) arrangement. This setup is ideal for applications requiring adjustable preload or axial displacement compensation, such as in gearboxes, wheel hubs, and industrial drivetrains.

### **Performance Benefits**

– **High Load Capacity:** Engineered to support heavy radial and axial loads simultaneously, making them ideal for gearboxes, conveyors, and heavy machinery.
– **Extended Service Life:** Advanced heat treatment and surface finishing reduce wear, ensuring reliable operation even in harsh environments.
– **Reduced Friction & Heat Generation:** Optimized roller profiles and premium lubrication compatibility enhance efficiency and reduce energy losses.
– **Versatile Mounting Options:** The 2TS IM’s indirect mount configuration allows for flexible installation in complex assemblies.

### **Typical Applications**

TIMKEN’s 2TS and 2TS IM bearings are widely used across industries where precision, durability, and high load capacity are critical:

– **Industrial Machinery:** Gear reducers, pumps, mining equipment, and material handling systems.
– **Automotive Systems:** Wheel hubs, differentials, and transmission assemblies.
– **Precision Equipment:** Machine tool spindles, printing presses, and robotics.

With over a century of bearing expertise, TIMKEN continues to set the standard for tapered roller bearing technology. The **2TS and 2TS IM Series** exemplify this legacy, offering engineers and maintenance professionals a trusted solution for maximizing equipment uptime and performance. Whether in high-speed, high-load, or harsh operating conditions, these bearings ensure reliability when it matters most.
