Metric Series
Metric Series Shaft Collars
Our metric series shaft collars are manufactured to strict dimensional tolerances to ensure a precise, secure fit on standard metric linear and rotary shafts. Designed for industrial power transmission assemblies, these components provide superior holding power and axial load registration without causing surface damage.
-
Bore Range: Standard metric sizing available to accommodate varied shaft diameters.
-
Design Configurations: Fully stocked in metric one-piece clamp, two-piece split clamp, and hardened set screw configurations.
Technical Specifications & Engineering Standards for Metric Shaft Collars
When integrating shaft collars into metric-designed machinery, alignment precision and hardware grading are critical to operational reliability. Our metric series is engineered to meet the demanding requirements of modern industrial automation and mechanical drive systems.
Precision Clamping & Torque Distribution
Unlike generic components, our metric clamping collars are machined with precise perpendicularity between the face and the bore. This ensures uniform face pressure and precise alignment when the collar is used as a mechanical stop or bearing retainer.
-
Metric One-Piece & Two-Piece Clamping: These designs leverage high-tensile metric socket head cap screws (typically ISO grade 12.9) to wrap uniformly around the shaft. The resulting friction-based mechanical lock maximizes holding torque while maintaining the integrity of ground shafts.
-
Metric Set Screw Type: Engineered with hardened cup-point set screws. This style provides reliable point-loading for static or low-load axial applications matching standard metric shaft flats.
Material Selection & Surface Finishes
To ensure compatibility with various operating environments, our metric shaft collars are available in multiple material grades:
-
Carbon Steel (Black Oxide Finish): Offers enhanced lubricity and mild corrosion resistance while maintaining maximum tensile strength for high-torque industrial clamping.
-
Stainless Steel (Grade 303 / 316): Ideal for food processing, medical packaging, and marine applications where frequent washdowns and chemical exposure occur.
