Screw Down Bearings

Design Principles: The reinforced integral inner and outer ring structure reduces cumulative assembly errors and improves structural stability under extreme loads. The optimized raceway curve design increases the contact area between rollers and raceways, evenly distributing combined radial and axial extreme loads to each roller, avoiding local stress concentration and adapting to high-frequency impact working conditions. High-temperature adaptation design: High-temperature resistant alloy materials are selected, and the surfaces of raceways and rollers are specially hardened to enhance wear resistance and anti-seizure ability at high temperatures; the cage is made of high-temperature stable materials to ensure operational reliability within the wide temperature range of -40°C to +200°C. Performance Features: Core Extreme Load Capacity: Reinforced materials and optimized contact design, with a maximum axial load of up to 40150 kN, 50% higher than conventional heavy-load bearings, adapting to the needs of ultra-heavy equipment. High-Temperature & Harsh Environment Resistance: Adapts to a wide temperature range of -40°C to +200°C, with outstanding dustproof, impact-resistant and corrosion-resistant performance, suitable for harsh working conditions such as high-temperature metallurgy and dusty mining. High Rigidity & Deformation Resistance: Integral structure + heavy-load reinforced materials, strong deformation resistance, ensuring operational accuracy and stability under extreme loads. Long Service Life & Wear Resistance: Surface hardening treatment + precision grinding process, roller end face Ra≤0.08μm, fatigue life and wear resistance increased by 60% compared with conventional bearings. Customization Options: Supports non-standard size (inner diameter/outer diameter/thickness) customization, material upgrade (high-temperature/corrosion-resistant materials), structure optimization (adaptation to specific equipment), lubrication solution customization (high-temperature/heavy-load dedicated grease), and seal type enhancement (composite seal structure).

Working Principle：Roller Arrangement and Load Distribution: Cylindrical rollers are evenly distributed within the reinforced raceway. Through optimized contact area design, radial and axial combined heavy loads are evenly transferred to the entire raceway surface, preventing localized overloading. Under extreme loads, the integral inner and outer ring structure provides strong support, suppressing deformation and ensuring load transfer efficiency and operational stability. In high-frequency impact conditions, the reinforced treatment of the rollers and raceway cushions impact energy, extending service life. - Thermal Management: High-temperature resistant materials and a low-friction cage design reduce friction loss and effectively control working temperature rise (typical temperature rise ≤25°C). Combined with the thermal stability of high-temperature-specific grease, this ensures thermal stability and operational reliability under high temperature and heavy load conditions. Installation Adaptability: The integral structure is compatible with standard interference fits (shaft h7/bore H7), accommodating the assembly tolerance requirements of most heavy-duty industrial equipment; standard mounting holes (M12–M48) are provided for direct bolt fixing, simplifying the installation process; the wide range of dimensions ensures compatibility with the assembly requirements of different models of heavy-duty equipment, ensuring precise installation and stable operation.
