#TIMJM511910
Product Overview
Timken manufactures ball bearings, cylindrical roller bearings, and tapered roller bearings, and all feature premium design, enhanced surface finishes, and are manufactured using quality materials to ensure longer bearing life and excellent antifriction properties.
Features & Benefits
- Single cup (outer ring) for connecting to cones (inner ring assemblies, sold separately) to form a complete single tapered roller bearing
- Supports both radial and axial loads between a rotating and non-rotating member
- Operating temperatures range from -54 to 120 degrees C (-65 to 250 degrees F)
- High alloy steel for durability and heat tolerance
- Open configuration for lubrication applied in place
