What is the primary function of a Hex & D Bore Shaft Collar?
Hex & D Bore Shaft Collars are used to secure components onto shafts, preventing axial movement and enabling precise positioning. The hex or D bore design ensures a non-slip fit, making them ideal for high-torque applications.
How do I choose between a hex bore and a D bore collar?
Select a hex bore collar for hexagonal shafts to maximize grip and torque transmission. For shafts with a flat side (D-shaped), use a D bore collar to prevent rotation and provide a secure hold. Consider the shaft shape and application requirements when choosing.
Are these collars reusable?
Yes, most Hex & D Bore Shaft Collars are designed for reuse. They can be loosened, repositioned, and retightened multiple times without significant wear, provided they are installed correctly and maintained properly.
What materials are best for corrosive environments?
Stainless steel collars are recommended for corrosive environments due to their excellent resistance to rust and chemicals. Aluminum collars are also a good option for lightweight applications with moderate corrosion exposure.
Can I get custom-sized Hex & D Bore Shaft Collars?
Absolutely. We offer custom manufacturing services for non-standard sizes and specifications. Contact our support team with your requirements, and we will provide a tailored solution to meet your needs.
How do I install a Hex & D Bore Shaft Collar properly?
To install, slide the collar onto the shaft to the desired position. For hex bore collars, align the hex shape with the shaft; for D bore, match the flat side. Tighten the set screws evenly using a torque wrench to the recommended specification, avoiding over-tightening to prevent shaft damage.
What maintenance is required for these collars?
Regular inspection for wear, corrosion, or loosening is advised. Lubricate the set screws periodically if specified, and ensure the collar remains clean from debris. No extensive maintenance is needed under normal operating conditions.
Are there alternatives to set screw collars?
Yes, clamping collars are an alternative that use a compression mechanism instead of set screws, reducing the risk of shaft scoring. However, hex and D bore collars with set screws are often preferred for their simplicity and cost-effectiveness.
What industries commonly use Hex & D Bore Shaft Collars?
These collars are prevalent in industries such as automotive manufacturing, agricultural machinery, conveyor systems, robotics, and aerospace, where reliable shaft securing is critical for operational efficiency.
How do I determine the correct size for my application?
Measure the shaft diameter accurately and refer to our size chart. Consider factors like load, speed, and environmental conditions. If unsure, consult with our engineering team for guidance based on your specific use case.
