SKF 99313 Speedi Sleeve – 3.15in Diameter, 0.750in Width, Painted

Description

Product Overview

The SKF 99313 Speedi Sleeve is a high‑quality shaft‑hub locking device engineered to meet the rigorous demands of modern industrial power transmission systems. Manufactured by SKF USA, a global leader in bearing and power transmission technology, this sleeve combines a robust painted exterior with precise dimensional tolerances to deliver consistent performance. The sleeve features a 3.15‑inch (80 mm) shaft diameter and a 0.750‑inch (19 mm) width, making it an ideal fit for a wide range of medium‑size shafts used in pumps, gearboxes, conveyors, and other rotating equipment. Its compact dimensions—9.84 × 0.91 × 3.94 inches—allow for easy integration into tight mechanical assemblies while maintaining a low overall weight of just 4.8 ounces, which helps reduce inertia and improve dynamic response.

Constructed from high‑strength steel and finished with a durable painted coating, the Speedi Sleeve offers excellent resistance to wear, corrosion, and environmental contaminants. The painted surface not only enhances visual identification during installation and maintenance but also serves as a protective barrier against moisture, chemicals, and abrasive particles that can compromise the integrity of the coupling over time. The sleeve’s center positioning ensures balanced load distribution across the shaft, minimizing stress concentrations and extending the service life of both the sleeve and the connected components.

Usage

This sleeve is designed for a broad spectrum of industrial applications where reliable torque transmission and secure shaft locking are essential. Typical usage scenarios include motor‑driven pumps, industrial fans, agricultural machinery, material handling equipment, and heavy‑duty conveyors. The Speedi Sleeve excels in environments that demand high reliability, such as continuous‑operation plants, harsh chemical processing facilities, and outdoor installations exposed to weather extremes. Its painted finish makes it suitable for applications where visual inspection is critical, allowing technicians to quickly verify proper installation and detect any signs of wear or damage.

Installation is straightforward: the sleeve slides onto the shaft, aligns with the center position, and is secured using the appropriate fasteners or set‑screws as specified in the equipment manual. Because the sleeve is vehicle‑specific and engineered for a precise fit, it eliminates the need for custom machining or extensive adjustments, reducing downtime and simplifying inventory management for maintenance teams. The product’s compatibility with standard SKF coupling families ensures seamless integration with existing systems, providing a cost‑effective upgrade path for facilities looking to improve performance without a complete redesign.
