How do I choose the right bore size for my machinery application?

Measure the outside diameter of your precision shaft using a digital caliper. Match the exact bore size specified on the collar, taking care to distinguish between inch-fractional sizes (like 1/4 inch or 3/8 inch) and metric millimeter sizes (like 5mm or 6mm). This Befenybay collar is designed for 5mm metric shafts.

Will tightening a set-screw shaft collar damage the underlying drive shaft?

Set-screw collars secure directly by driving the screw tip against the shaft surface, which can leave small indentations or burrs on softer metal shafts. For applications where shaft marring must be avoided, consider using a flat point screw, a dimpled shaft flat, or a clamp-style collar. The M3 set screws included here are standard.

Is this Befenybay shaft lock collar suitable for Indian machinery?

Yes, this collar is designed for 5mm metric shafts, which are standard in many Indian industrial applications. For machinery using imperial inch shafts, you would need a collar with a corresponding inch bore size. This imported option provides a reliable solution for your metric shaft needs.

What is included in the Befenybay 5mm shaft lock collar set?

The set includes 10 pieces of 5mm shaft lock collars, 10 corresponding set screws, and one M3 hex wrench for installation. This comprehensive package ensures you have all the necessary components for immediate use on your projects.

Why choose this product

Engineered for Precision Motion Control

Befenybay shaft lock collars are designed for applications demanding precise alignment and secure component fixation. Unlike generic washers, these collars are specifically engineered with a 5mm bore and robust set screw mechanism to prevent shaft slippage, crucial for CNC machines and robotics. The 45# steel construction ensures durability, resisting wear and maintaining holding power over time. This imported solution offers the quality needed for critical mechanical assemblies, ensuring your equipment operates smoothly and accurately.

Ideal for Metric Shafts, Consider Alternatives for Inch-Sized Shafts

These collars are perfectly suited for standard 5mm metric shafts commonly found in Indian machinery. If your application uses imperial inch-sized shafts (e.g., 1/4 inch or 3/8 inch), you will need to source collars with corresponding imperial bore sizes. While these collars provide excellent value, users requiring absolute zero shaft marring might consider clamp-style collars or shafts with pre-drilled flats for set screw engagement.

How to use

Position the Collar — Slide the Befenybay shaft lock collar onto the 5mm shaft at the desired location, ensuring it is flush against the component it needs to secure.
Insert and Tighten Set Screw — Using the provided M3 hex wrench, insert one of the set screws into the collar's threaded hole and tighten it firmly against the shaft surface.
Secure the Collar — Continue tightening the set screw until the collar is securely locked onto the shaft, preventing any axial or rotational movement. Ensure it does not overtighten and damage the shaft excessively.
