This manufacture two-piece clamp shaft collars in Carbon steel with a proprietary black oxide finish. 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. Keep both halves of the split collar together throughout the manufacturing process to assure a perfect match for proper fit, alignment and holding power. This process also makes the two-piece collar more adaptable to shafts which vary a small amount from nominal size. Suitable for nearly all types of machinery and industry, such as drive shafts, agricultural implements, medical equipment, gearbox assemblies, motor bases, machine tools, and paper and steel mill equipment, the automotive industry, the manufacturing industry, the hobby craft industry.
