    Two-Piece Shaft Collars

    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. Ruland keeps 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. Ruland manufactures two-piece clamp shaft collars in 1215 lead-free steel with a zinc or proprietary black oxide finish, 303 and 316 stainless steel, high-strength 2024 aluminum with or without an anodize finish, titanium, and engineered plastic. Bore sizes range from 1/8" to 6" and 3mm to 150mm.
