Product Overview: The 23138 Spherical Roller Bearing
The 23138 Spherical Roller Bearing is a high-capacity, robust component engineered for the most demanding industrial applications. With key dimensions of 190x320x104mm, this bearing is a prominent part of our 23100 Series within the broader Spherical Roller Bearings collection. Its defining feature is the ability to accommodate severe misalignment between the shaft and housing, making it indispensable in machinery where shaft deflection or mounting errors are unavoidable. The bearing's internal design, featuring two rows of symmetrical barrel rollers and a common sphered outer ring raceway, allows it to handle very heavy radial loads and significant axial loads in both directions.
As a specialist supplier of industrial components, we ensure our 23138 bearings meet stringent quality standards, providing exceptional reliability and a long service life. This bearing is a cornerstone in heavy machinery, ensuring smooth and efficient operation under extreme conditions. For mounting on a cylindrical shaft, it is commonly used with an H 3138 adapter sleeve.
Key Features of the 23138 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment, reducing stress on the shaft and extending the life of the machine.
- High Load Capacity: Designed with two rows of rollers to support extremely high radial loads and substantial axial loads in both directions.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior durability and resistance to wear and fatigue.
- Optimized Internal Design: Features symmetrical barrel rollers that ensure optimal load distribution and reduce friction, even under heavy loads.
- Cage Variants: Typically available with strong steel or brass cages to withstand high temperatures, acceleration, and vibration.
- Mounting Versatility: Can be mounted directly onto a tapered shaft or onto a cylindrical shaft using a suitable adapter sleeve.
Common Applications of 23138 Bearings
- Mining and Construction: Used in heavy-duty equipment such as rock crushers, vibrating screens, and conveyor systems.
- Pulp and Paper Mills: Essential for rollers in paper machines, calenders, and press sections where heavy loads and misalignment are common.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale transmission systems.
- Wind Turbines: Utilized in the main shafts and gearboxes of wind energy systems to handle fluctuating, heavy loads.
- Steel Manufacturing: Found in continuous casting machines, rolling mills, and other high-temperature, heavy-load applications.
- Marine and Offshore: Employed in propulsion systems, winches, and cranes where reliability is critical.
- Large Fans and Blowers: Supports industrial ventilation systems that operate under demanding conditions.
Benefits of Using the 23138 Bearing
- Enhanced Machine Uptime: The bearing's ability to handle misalignment and heavy loads reduces the risk of premature failure and costly downtime.
- Extended Service Life: Superior design and materials contribute to a long operational life, even in harsh environments.
- Reduced Maintenance Costs: High reliability and durability mean less frequent inspection, lubrication, and replacement.
- Improved Operational Efficiency: Low-friction characteristics help to minimize energy consumption and heat generation.
- Simplified Assembly: The self-aligning feature can simplify the machine design and mounting process, saving time and effort.
- Versatile Performance: Suitable for a wide range of heavy industrial sectors, making it a flexible solution for complex engineering challenges.
