The main difference between clamp-on and set screw couplings lies in the method used to secure the collar onto the shaft. Clamp-on couplings utilize a clamping mechanism, often screws or levers, to tightly grip the shaft and provide a secure connection. On the other hand, set screw couplings use a set screw that is tightened against the shaft to hold the collar in place. Both types offer effective shaft-to-component connections, but clamp-on couplings generally provide higher holding power and are more suitable for demanding applications where strong axial holding is required.

Split shaft collars are commonly used for applications where it is difficult or impossible to slide a traditional, solid collar onto a shaft. They are designed with a two-piece construction that can be easily installed or removed by tightening or loosening the screws or clamps. Split shaft collars provide a reliable means of securing components such as bearings, sprockets, or pulleys onto shafts while allowing for easy adjustment or disassembly.

A shaft collar clamp is a type of collar that utilizes a clamp mechanism for secure fastening and positioning on a shaft. It typically consists of two halves with a screw or a lever-operated mechanism that tightens the collar around the shaft, creating a strong grip. Shaft collar clamps are commonly used in applications where a high level of axial holding power is required, ensuring components remain fixed in their desired positions on the shaft even under demanding conditions.

When selecting a shaft collar in the UK, consider factors such as size (e.g., 10mm, 40mm), material (e.g., stainless steel), and type (e.g., split collars, clamp collars) to ensure proper fit and performance for your specific application needs.
