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 6mm or 10mm). For this Befenybay collar, the bore size is precisely 6mm.

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. These Befenybay collars use standard cup point set screws.

Is this Befenybay shaft lock collar suitable for Indian manufacturing environments?

Yes, these lock collars are suitable for Indian manufacturing. While the silver steel offers good durability, in high-humidity environments, periodic anti-rust oiling might be beneficial for longevity. For extreme corrosion resistance, consider stainless steel alternatives if available.

How do I buy an original Befenybay 6mm shaft lock collar in India?

Purchase original Befenybay 6mm shaft lock collars sourced from authorized US retailers and authorized brand partners, factory-sealed and imported per-order. All customs duties and GST are included in the listed INR price, with ExpressBox tracked delivery to your pincode.

What is the difference between this lock collar and local alternatives?

This Befenybay lock collar is imported and offers consistent material quality and dimensional accuracy. Local alternatives may vary significantly in their steel grade, set screw quality, and bore tolerance, potentially leading to less secure fits or premature wear. Our imported collars provide reliable performance backed by clear specifications.

Why choose this product

Engineered for Reliable Shaft Locking

These Befenybay shaft lock collars are designed for precision and durability. Constructed from 45# steel with a silver finish, they offer a secure fit for 6mm shafts and T6 lead screws. The included set screws provide solid holding power, crucial for CNC parts and power transmission systems. Unlike generic local options that may vary in material quality and dimensional accuracy, these collars are sourced from authorized US retailers and authorized brand partners, ensuring consistent performance and reliability for your critical machinery components.

Ideal for CNC and Power Transmission

This 10-piece set is perfect for engineers, hobbyists, and manufacturers working with CNC machines, robotics, or any power transmission application requiring secure shaft fixation. The 6mm bore size is standard for many applications. While these collars offer excellent holding power, users with extremely soft shafts or those requiring absolutely zero surface marring might consider a clamp-style collar or a flat-point set screw alternative. For most standard industrial and DIY uses, these set-screw collars provide a cost-effective and reliable solution.

How to use

Select the Correct Shaft — Ensure the shaft diameter precisely matches the collar's bore size, which is 6mm for this Befenybay set. Verify the shaft is clean and free of debris for optimal contact.
Position the Collar — Slide the lock collar onto the shaft at the desired location. Align the set screw hole so it can be tightened directly against the shaft surface.
Tighten the Set Screw — Using the provided M3 hex wrench, firmly tighten the set screw against the shaft. Apply sufficient torque to ensure a secure hold without overtightening, which could damage the shaft.
