A locking assembly is a high-precision mechanical component designed to connect hubs and shafts without the need for keys, splines, or tapered bushes. It provides a friction-based, backlash-free connection that is ideal for applications requiring high torque transmission, easy mounting, and dismounting. Locking assemblies are widely used in industries such as manufacturing, mining, conveyor systems, and renewable energy.
Our locking assemblies are engineered to meet international standards, including ISO and DIN specifications. Below is a detailed table of product parameters for common models.
| Model Number | Shaft Diameter Range (mm) | Hub Bore Range (mm) | Max Torque (Nm) | Max Speed (RPM) | Material | Operating Temperature (°C) |
|---|---|---|---|---|---|---|
| LA-1020 | 20 - 50 | 25 - 55 | 500 | 4000 | Carbon Steel | -20 to 120 |
| LA-1040 | 40 - 80 | 45 - 85 | 1200 | 3500 | Stainless Steel | -30 to 150 |
| LA-1060 | 60 - 100 | 65 - 105 | 2500 | 3000 | Alloy Steel | -40 to 200 |
| LA-1080 | 80 - 120 | 85 - 125 | 4000 | 2500 | Carbon Steel with Coating | -20 to 180 |
| LA-1100 | 100 - 150 | 105 - 155 | 6000 | 2000 | Stainless Steel | -30 to 160 |
What is the primary advantage of using a locking assembly over traditional keyed connections?
Locking assemblies eliminate the need for keyways, which reduces stress concentrations and minimizes wear. They provide a more uniform load distribution, higher torque capacity, and allow for easier adjustment and maintenance compared to keyed connections.
Can locking assemblies be used in high-temperature environments?
Yes, many of our locking assemblies are designed to operate in temperatures up to 200°C, depending on the material. For instance, models made from alloy steel or with special coatings can withstand extreme conditions without loss of performance.
How do I select the right locking assembly for my application?
Consider factors such as shaft diameter, hub bore, required torque, operational speed, and environmental conditions. Our technical team can assist with selection based on your specific parameters to ensure optimal performance.
Are locking assemblies reusable?
Yes, locking assemblies are designed for multiple uses. They can be dismounted and remounted without significant wear, making them cost-effective for applications requiring frequent adjustments or maintenance.
What maintenance is required for locking assemblies?
Regular inspection for signs of wear, corrosion, or loosening is recommended. Ensure screws are tightened to the specified torque during routine maintenance. In corrosive environments, consider stainless steel models or apply protective coatings.
Do locking assemblies work on tapered shafts?
While primarily designed for cylindrical shafts, some specialized locking assemblies can accommodate tapered shafts. Please contact our support team for custom solutions based on your shaft geometry.
What is the maximum speed at which locking assemblies can operate?
The maximum speed varies by model, ranging from 2000 to 4000 RPM as shown in the technical table. Always refer to the product specifications and ensure the assembly is within the safe operating range to prevent centrifugal forces from affecting performance.
Can locking assemblies be used in underwater applications?
Yes, with appropriate materials such as stainless steel and corrosion-resistant coatings, locking assemblies can function in submerged or high-moisture environments. Specify your conditions when ordering to receive a suitable product.
