SKF 99347 Speedi Sleeve Shaft Locking Device, Stainless Steel, 3.5in

Description

Product Overview

The SKF 99347 Speedi Sleeve is engineered as a precision‑fit shaft‑hub locking device crafted from high‑grade stainless steel, delivering exceptional corrosion resistance and structural integrity in harsh industrial environments. Measuring 3.5 inches in shaft diameter with a 0.625‑inch width, the sleeve provides a snug, secure fit for a wide range of shaft applications, from cabinet assemblies to heavy‑duty power transmission systems. Its exterior is finished with a durable painted coating that not only enhances visual appeal but also adds an extra layer of protection against wear, abrasion, and chemical exposure. The compact dimensions—9.84 × 0.91 × 3.94 inches—allow for easy integration into confined spaces without sacrificing strength. Designed for a one‑piece installation, the Speedi Sleeve eliminates the need for additional fasteners or complex assembly steps, streamlining the installation process and reducing labor costs. With a weight of just 4.8 ounces, it is lightweight enough for rapid handling yet robust enough to withstand the torque and shear forces typical of industrial machinery.

Usage

This shaft‑hub locking sleeve is ideally suited for a variety of applications where reliable torque transmission and shaft alignment are critical. Common use cases include securing motor shafts within cabinet enclosures, coupling shafts in conveyor systems, and stabilizing shafts in agricultural equipment. The stainless‑steel construction makes it an excellent choice for environments exposed to moisture, chemicals, or temperature fluctuations, such as food processing plants, chemical handling facilities, and outdoor machinery. Installation is straightforward: the sleeve slides onto the shaft, aligns with the pre‑drilled bore, and locks in place with a simple press‑fit action, eliminating the need for welding or additional hardware. Its painted finish also helps to reduce visual glare in low‑light workspaces, improving safety for technicians performing maintenance or inspection tasks. Because the Speedi Sleeve is compatible with standard 3.5‑inch shafts, it can be retrofitted into existing equipment, extending the service life of legacy machinery while delivering modern performance standards.

FAQ

What shaft sizes are compatible with the SKF 99347 Speedi Sleeve?

The Speedi Sleeve is specifically designed for shafts with a 3.5‑inch (approximately 89 mm) diameter. It accommodates a width of 0.625 inches, providing a secure fit for standard industrial shafts within this size range.

Is the painted finish suitable for outdoor or corrosive environments?

Yes. The painted coating is formulated to resist moisture, UV exposure, and chemical splashes, making the sleeve appropriate for outdoor installations and environments where corrosion resistance is essential.

Can the sleeve be retrofitted onto existing equipment?

Absolutely. Because the sleeve conforms to standard shaft dimensions, it can be installed on legacy machinery without requiring major modifications, allowing you to upgrade older equipment with a modern, reliable locking solution.

What warranty does SKF provide for this product?

SKF offers a standard limited warranty that covers material defects and workmanship for a period of one year from the date of purchase, along with access to technical support for installation and troubleshooting.

How does the Speedi Sleeve compare to traditional keyed shafts?

Unlike keyed shafts that require machining and additional hardware, the Speedi Sleeve provides a seamless, keyless locking mechanism that simplifies assembly, reduces part count, and minimizes the risk of misalignment, while delivering comparable torque transmission capabilities.
