The TB Wood's BK130 12.75" x 1-3/16" Finished Bore FHP Sheave is a precision-engineered component designed to optimize power transmission in light-duty fractional horsepower (FHP) applications. Manufactured from high-quality cast iron, this sheave offers exceptional durability and resistance to wear, ensuring reliable performance in various industrial settings. Its 12.75-inch outside diameter and 1-3/16-inch finished bore make it compatible with B section V-belts, accommodating a wide range of machinery requirements. The sheave features a single groove, facilitating efficient belt engagement and minimizing slippage, which is crucial for maintaining consistent operational speeds and reducing energy losses. Designed for easy installation, the BK130 sheave can be equipped with TB Wood's Sure-Grip‚ Quick Detachable (QD) bushings, which provide a true clamp on the shaft comparable to a shrink fit. This design simplifies maintenance procedures and reduces downtime, enhancing overall operational efficiency. With a maximum operating speed of 1,970 RPM, the BK130 sheave is suitable for applications requiring moderate rotational speeds. Its lightweight construction, weighing approximately 9.6 pounds, contributes to reduced system inertia, allowing for quicker acceleration and deceleration, which is beneficial in applications where rapid speed changes are necessary. By integrating the TB Wood's BK130 sheave into your power transmission system, you can achieve improved efficiency, reduced maintenance costs, and enhanced operational reliability, thereby adding measurable value to your fleet operations.
