Description
HARKEN Zircon 57mm Double Block – 2197
HARKEN Zircon 57mm Double Block – 2197 uses Harken Zircon low-friction block technology for high-performance control systems where sensitivity and very free running are important.
- Zircon blocks feature industrial ceramic (Zirconia) ball bearings mounted in caged races for ultra-smooth performance.
- Caged bearings prevent bunching and contact, delivering a very free-running block with minimal friction.
- Bearings are over 700% stronger in compression than stainless steel bearings of the same size.
- Resistant to deformation when used within recommended load limits.
- Absorb less energy before rolling , improving efficiency and line handling.
