Product Overview: H 30/670 Adapter Sleeve
The H 30/670 is a high-precision adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 670mm diameter. As a key component in our Adapter Sleeves collection and a part of the robust H 3000 Series, this sleeve provides a simple, reliable, and cost-effective method for securing large bearings. The assembly, which includes the adapter sleeve, a suitable lock nut, and a locking device, ensures a tight fit and facilitates easy installation and removal without the need for complex shaft machining.
Adapter sleeves are one of the most commonly used components for locating bearings, allowing them to be positioned at any point along a plain shaft. The H 30/670 is manufactured to precise tolerances, ensuring accurate alignment and dependable performance in heavy-duty industrial applications. When the lock nut is tightened, the sleeve is pressed into the bearing's tapered bore, creating a strong interference fit that securely fastens the bearing to the shaft.
Key Features of the H 30/670
- Simplified Mounting: Enables easy installation of tapered bore bearings onto standard cylindrical shafts.
- Secure Fixation: Provides a strong, reliable interference fit when tightened with a corresponding lock nut.
- Versatile Positioning: Allows the bearing to be located at any position along the shaft.
- Precision Engineered: Machined to strict industry standards for optimal fit and performance.
- Complete System: Designed to be used with a lock nut and locking washer/clip for a secure assembly.
- Durable Construction: Made from high-strength steel to withstand demanding operational forces.
Common Applications
- Mining and Construction: Used in large crushers, conveyors, and heavy earth-moving equipment.
- Pulp and Paper Mills: Essential for mounting bearings on large rollers and processing machinery.
- Steel Manufacturing: Applied in rolling mills, continuous casters, and other high-load machinery.
- Power Generation: Suitable for turbines, large gearboxes, and generator shafts.
- Industrial Fans and Blowers: Provides stable mounting for large fan assemblies in ventilation systems.
- Marine Propulsion Systems: Used in propeller shafts and other critical maritime applications.
- Cement Plants: Employed in kilns, grinding mills, and large transmission systems.
Benefits of Using the H 30/670 Adapter Sleeve
- Cost-Effective Assembly: Eliminates the need for expensive stepped or specially machined shafts.
- Enhanced Reliability: Ensures a firm and concentric grip on the shaft, reducing vibration and improving bearing life.
- Reduced Maintenance Time: The design simplifies both the mounting and dismounting process, minimizing machinery downtime.
- Improved Operational Safety: When correctly installed with its locking components, it prevents axial loosening of the bearing.
- Design Flexibility: Offers engineers greater freedom in designing shaft and bearing arrangements.
- Shaft Protection: Avoids the need for keyways that can weaken the shaft and act as stress concentration points.
