Saelno H1 Split Tapered Locking Bushing 24mm Bore Black Finish

Description

Product Overview

The Saelno H1 split-tapered locking bushing is engineered for precision mechanical applications where a firm, repeatable connection between a shaft and a pulley is essential. Featuring a 24 mm bore that matches a 1‑inch shaft diameter, the bushing incorporates standard keyseats of 1/4×1/8, allowing for easy key insertion and torque transmission. Constructed from ASTM 1045 carbon steel, the component offers a balance of strength and machinability, while a specialized black oxidation treatment provides superior corrosion resistance, extending service life even in harsh industrial environments.

Designed to lock H‑type taper pulleys and sheaves, the bushing includes two 1/4‑20UNC×3/4 screws that secure the assembly to the shaft. The split‑taper design enables the bushing to be inserted and aligned with the threaded hole of the pulley, then tightened to create a rigid, non‑slipping joint. Package dimensions of 2.68 × 2.68 × 1.46 inches and a weight of 10.23 ounces make the part easy to handle during installation and maintenance.

Usage

This locking bushing is ideal for a wide range of industrial and scientific equipment, including conveyor systems, material handling gear, and precision drive mechanisms. Its robust construction makes it suitable for high‑speed applications where vibration and thermal cycling are common. The black oxidation surface not only prevents rust but also reduces visual glare, which can be advantageous in environments where safety lighting is critical.

Typical installation scenarios involve inserting the bushing into a pulley housing, aligning the smooth bore with the shaft, and then tightening the supplied screws. The design ensures that the bushing remains firmly seated, preventing axial movement and maintaining accurate belt or rope tension. Users in manufacturing, automation, and laboratory settings will appreciate the ease of replacement and the consistent performance over repeated assembly cycles.

FAQ

What shaft sizes are compatible with the H1 bushing?

The bushing is designed for a 1‑inch (25.4 mm) shaft diameter, providing a 24 mm bore that fits standard industrial shafts with a 1‑inch nominal size.

Can the bushing be used with non‑H‑type pulleys?

While the split‑tapered design is optimized for H‑type taper pulleys, it can be adapted to other pulley types that accept a split‑tapered locking mechanism, provided the mounting holes align with the bushing’s threaded screw locations.

How does the black oxidation treatment improve performance?

The oxidation layer creates a dense, adherent coating that significantly reduces the rate of corrosion, especially in humid or chemically aggressive environments, while maintaining the part’s dimensional stability.

Is the bushing reusable after removal?

Yes, the bushing can be removed and reinstalled multiple times without compromising its structural integrity, as long as the screws are not over‑torqued and the surface coating remains intact.

What is the recommended torque for the installation screws?

Saelno recommends tightening each 1/4‑20UNC×3/4 screw to approximately 8‑10 Nm (70‑90 in‑lb) to achieve a secure lock without overstressing the threads.
