Thrust Spherical Roller Bearings-Type TSR

**TIMKEN Thrust Spherical Roller Bearings (Type TSR): Engineered for Heavy-Duty Performance**

TIMKEN Thrust Spherical Roller Bearings (Type TSR) represent a pinnacle of engineering excellence, designed to handle extreme axial loads, misalignment, and harsh operating conditions with unmatched reliability. As a leader in advanced bearing technology, TIMKEN has developed these bearings to deliver superior performance in demanding industrial, automotive, and heavy machinery applications where high thrust capacity and durability are critical.

### **Technical Features & Design Advantages**
TIMKEN TSR thrust bearings incorporate a robust spherical roller design, enabling them to accommodate heavy axial loads combined with moderate radial loads. Their self-aligning capability—up to **±2° misalignment**—ensures optimal performance even in applications with shaft deflection or mounting inaccuracies. Key features include:

– **Optimized Roller Geometry**: Asymmetrical barrel-shaped rollers distribute load evenly, reducing stress concentrations and extending service life.
– **High-Capacity Design**: Engineered for **maximum load-carrying efficiency**, TSR bearings utilize a full complement of rollers or guided cage assemblies to handle extreme thrust forces.
– **Advanced Materials & Heat Treatment**: Manufactured from premium clean steel and subjected to precision heat treatment, these bearings resist wear, fatigue, and deformation under heavy loads.
– **Enhanced Lubrication Retention**: Innovative raceway and roller profiles improve lubricant distribution, reducing friction and heat generation in high-speed applications.

### **Performance Benefits**
TIMKEN TSR thrust bearings excel in applications where conventional thrust bearings fall short. Their ability to operate under **shock loads, vibration, and misalignment** makes them indispensable in industries requiring uncompromising reliability. Benefits include:

– **Extended Service Life**: Reduced metal-to-metal contact and optimized internal geometry minimize wear, lowering maintenance costs.
– **Reduced Downtime**: Robust construction and contamination resistance enhance operational uptime in harsh environments (e.g., mining, cement, or metal processing).
– **Energy Efficiency**: Low friction design contributes to lower power consumption in high-load systems.

### **Typical Applications**
TIMKEN TSR bearings are widely used in heavy industrial and precision equipment, including:
– **Industrial Machinery**: Gearboxes, extruders, and rolling mills where axial loads dominate.
– **Mining & Construction**: Vibratory screens, crushers, and conveyor systems exposed to shock loads.
– **Marine & Hydraulic Systems**: Propulsion systems, pumps, and offshore equipment requiring corrosion resistance.
– **Wind Energy**: Pitch and yaw control mechanisms in turbine systems.

### **Why Choose TIMKEN?**
Backed by over a century of innovation, TIMKEN’s TSR thrust bearings combine cutting-edge design with rigorous testing to ensure peak performance. Whether in extreme environments or precision applications, they provide the durability and efficiency needed to keep critical machinery running smoothly.

For industries demanding **high-load capacity, misalignment tolerance, and long-term reliability**, TIMKEN Thrust Spherical Roller Bearings (Type TSR) set the standard for excellence in mechanical power transmission.
