description
- With more than a century of knowledge and innovation, Timken is an industry-leader in designing, manufacturing and applying high performance engineered bearings into our customers’ most challenging applications. With one common global quality system across all manufacturing plants, we deliver consistent product performance and reliability anywhere in the world. As a Timken customer, you are connected to a team of application, sales and on-site service engineers who help solve unique equipment challenges resulting in extended uptime, productivity and efficiency. We are a recognized global leader in spherical roller bearings, with a manufacturing history going back to the early 1900s. With one of the broadest ranges of spherical roller bearings and assemblies fitting shafts of 25mm to 2500mm, our team can help provide the optimal solution for your application. Designed to meet the toughest application conditions, our Spherical Roller Bearings can increase productivity and uptime in your equipment due to optimized internal geometry and higher capacity, resulting in longer bearing life. Timken Spherical Roller Bearings can also lead to more productivity and uptime thanks to lower operating temperatures resulting in extended lubrication life and reduced lubricant usage.
applications
- Pulp and paper mills
- Construction and mining equipment
- Metal mills
features
- Longer bearing life achieved from higher capacity (vs. competitors)
- Longer lubrication life achieved from lower operating temperatures due to reduced internal friction and running torque from cage guided rollers
- Better contaminant purging from slots on cage face helps extend bearing life
- Greater fatigue strength and increased wear resistance provide tougher protection against shock and acceleration loading from a hardened steel cage
