Shaft collar is used for axial positioning of parts. It is an additional structure on the shaft and regarded as a part of the shaft. The clamping shaft collar can be divided into one-piece collar and two-piece collar.
One-piece shaft collars wrap around the shaft for even distribution of clamping forces. This results in a tight fit and greater holding power, without the shaft damage caused by set screws. Clamp collars are easy to remove, indefinitely adjustable, and work well on virtually any shaft.
Two-piece shaft collars offer the same benefits as the one-piece style with additional versatility and convenience. The split design is easily installed and disassembled, reducing labor and downtime when adjustment, removal, or replacement is necessary. The two-piece shaft collar uses the full seating torque of its forged screws to apply a uniform distribution of forces around the shaft’s circumference. These clamping forces provide the collar with a holding power superior to one-piece and set screw shaft collars.
The shaft collars provided by ISUTAMI are generally made of lead-free steel or stainless steel with a zinc or black oxide coating on the surface. It can also be made of high-strength aluminum, nylon or engineering plastics. We offer regular size products, including inch and metric sizes.
