Tension block, 3,5

Description

The 3.5" (89 mm) diameter tension block (roller) from Big Dutchman is a highly reliable power unit for suspension systems, designed to change the direction and tension of steel cables that hold feeding and watering lines. Its cast iron construction and serviceable bearing make this block ideal for use under high static and dynamic loads. Technical advantages and engineering features: - Cast iron housing: The use of cast iron technically ensures exceptional wear resistance of the trough. Unlike plastic counterparts, the cast iron block is not worn down by the steel cable even under intensive use, maintaining perfect rolling geometry. - Integrated bearing with grease nipple: The presence of a grease nipple allows for regular maintenance. This technically guarantees a minimum friction coefficient and prevents the roller from jamming, which is especially important in conditions of high dustiness in the poultry house. - Protective polymer coating: The bright orange color not only protects the metal from the aggressive effects of ammonia (NH3) and moisture, but also serves as a safety indicator, allowing visual monitoring of the condition of the unit under the ceiling. - Optimized trough radius: The pulley geometry is designed to work with cables of different diameters, ensuring maximum contact area. This technically reduces the internal tension in the cable, preventing premature breakage and fiber loosening.
