Flange Mount Shaft Collar with Split Clamp Design
Flange-mounted shaft collar with split clamp and hex screw for secure axial holding and easy positioning. Made of aluminum or stainless steel, suitable for motion systems and mounting plates. Material and dimensions customizable.
This flange mount shaft collar offers both axial holding power and easy installation, combining a precision-machined collar with an integrated mounting flange. The split clamp design ensures a tight, even grip around the shaft without marring or deformation, while the flange provides a stable base for mounting to surfaces, plates, or equipment frames.
The collar is fastened using a hex socket screw, which allows quick adjustment and reliable locking. Ideal for use in automation, linear motion systems, rotating shafts, and fixture assemblies, this product simplifies alignment, limits shaft movement, and securely attaches components in fixed positions.
Available in lightweight aluminum or corrosion-resistant stainless steel, and offered in a range of bore diameters, mounting patterns, and thicknesses.
