Spherical Roller Bearings – Brass Cage

TIMKEN Product Introduction

**TIMKEN Spherical Roller Bearings with Brass Cage: Engineered for Durability and High Performance**

TIMKEN Spherical Roller Bearings with brass cages represent a pinnacle of engineering excellence, designed to deliver unmatched reliability in demanding industrial and automotive applications. These bearings are built to accommodate heavy radial and axial loads while compensating for misalignment, making them indispensable in harsh operating environments. The incorporation of a high-strength brass cage enhances performance, ensuring smooth operation, reduced friction, and extended service life—even under extreme conditions.

### **Technical Features & Design Advantages**
TIMKEN’s Spherical Roller Bearings are precision-engineered with a self-aligning design, allowing them to tolerate shaft misalignment up to **±3 degrees**, which minimizes stress concentrations and prevents premature failure. The **brass cage (also known as a brass retainer)** plays a critical role in these bearings by offering superior mechanical stability, excellent heat dissipation, and resistance to wear compared to steel or polymer cages.

Key technical attributes include:
– **High Load Capacity:** Optimized roller geometry and premium steel construction enable these bearings to handle heavy radial and axial loads simultaneously.
– **Enhanced Lubrication Retention:** The brass cage aids in maintaining proper lubricant distribution, reducing metal-to-metal contact and wear.
– **Thermal & Corrosion Resistance:** Brass provides inherent resistance to high temperatures and corrosive environments, making these bearings ideal for applications exposed to moisture, dust, or chemicals.
– **Low Maintenance & Longevity:** The robust cage design minimizes friction and prevents roller skewing, significantly extending bearing life even in high-speed applications.

### **Performance Advantages in Industrial & Automotive Systems**
TIMKEN Spherical Roller Bearings with brass cages excel in applications where reliability and durability are non-negotiable. Their ability to operate under misaligned conditions reduces downtime in heavy machinery, while their resistance to thermal expansion ensures consistent performance in high-temperature settings.

### **Typical Applications**
– **Industrial Machinery:** Used in gearboxes, crushers, mining equipment, and conveyor systems where shock loads and misalignment are common.
– **Automotive & Heavy Vehicles:** Ideal for wheel hubs, transmissions, and drivetrains in trucks, buses, and off-highway vehicles.
– **Precision Equipment:** Applied in paper mills, wind turbines, and steel processing lines where alignment flexibility and load capacity are critical.

By combining advanced metallurgy, precision manufacturing, and innovative cage design, TIMKEN’s Spherical Roller Bearings with brass cages set the benchmark for performance in mechanical power transmission. Whether in high-load industrial systems or precision automotive components, these bearings ensure **longer service life, reduced maintenance costs, and superior operational efficiency**.

For industries that demand resilience under pressure, TIMKEN continues to deliver solutions that keep machinery running smoothly—proving once again why it is a trusted name in power transmission technology.
