Dual-Clamp Design for Reliable Shaft Positioning

Double split collars provide a balanced clamping solution where both installation convenience and holding performance matter. By distributing force across two independent clamping points, these collars achieve more uniform pressure while minimizing shaft deformation—particularly valuable in precision equipment and high-vibration environments.

Technical Capabilities:
The dual-screw configuration creates 35% greater holding power compared to single-split designs, with pressure distribution improved by 80% around the shaft circumference. Manufactured from Grade 1045 steel with heat-treated options, the collars maintain dimensional stability across temperatures ranging from -40°C to 120°C. Surface treatments including zinc plating and anodization provide corrosion resistance validated through 500+ hour salt spray tests.

Performance Characteristics:
Engineered to withstand accelerations up to 15g, these collars maintain position in demanding robotic and automated applications. Installation time is reduced by approximately 40% compared to solid collars, with no shaft damage due to controlled surface pressure below material yield limits. Engineering plastic versions sustain performance through over 1 million load cycles in dynamic applications.

Industrial Applications:
In industrial robotics, these collars reliably position sensors and limit switches on articulated arms operating at 2-5 Hz cycles. Packaging machinery benefits from their vibration resistance at speeds exceeding 120 cycles per minute. Renewable energy applications utilize their environmental durability in solar tracking and wind turbine systems, while electric vehicle manufacturing employs them in battery assembly and motor testing stations. Food processing facilities select USDA-compliant versions for washdown environments using pH 2-12 cleaning solutions.

Engineering Specifications:
Torque specifications range from 2.5 to 25 Nm based on size and material selection, with runout tolerance maintained within 0.1 mm for precision requirements. Static load capacity reaches 5,000 N without deformation, supported by compliance with ISO 9001:2015 and RoHS standards. The global shaft collar market continues to grow at 6.2% CAGR, reflecting increased automation across industries.

Material Selection:
Carbon steel options provide 500-700 MPa tensile strength for general industrial use. Stainless steel 304/316 variants offer corrosion resistance in chemical and marine environments. Aluminum 6061 delivers 35% weight reduction with 200 MPa yield strength, while acetal copolymer serves precision instruments with its 0.1-0.3 friction coefficient.

Available in bore sizes from 6 mm to 150 mm with custom configurations, double split collars combine practical installation advantages with engineering-grade performance for today's automated systems.
