Regal Split Tapered Locking Bushing External Key

Description

Product Overview

Regal’s split‑tapered locking bushing is engineered for demanding industrial environments where torque transmission and precise alignment are critical. Constructed from hardened steel, the bushing incorporates an external key on most sizes, enabling a positive drive that significantly increases torque carrying capability. The double‑split barrel design provides reliable, positive clamping, while a solid flange preserves concentric bore geometry, reducing run‑out and wear. Available in both inch and metric dimensions, the bore range spans from 3/8″ to 10″, covering a wide array of applications from hydraulic assemblies to heavy‑duty gearboxes. Package dimensions are compact at 4.5 x 4.3 x 2.6 inches, weighing just under 5 ounces, making storage and handling straightforward.

Usage

This bushing excels in high‑stress settings such as manufacturing equipment, agricultural machinery, and construction tools where reliable torque transfer is essential. Installers benefit from the external key, which simplifies alignment and eliminates slippage during assembly. The design tolerates both metric and imperial shafts, allowing seamless integration into existing systems without the need for custom machining. Target users include maintenance technicians, mechanical engineers, and procurement specialists seeking a durable, low‑maintenance solution for power transmission components.

Why Choose Us

Regal brings decades of expertise in industrial fasteners, ensuring each bushing meets rigorous quality standards. The combination of a solid flange and double‑split barrel delivers superior concentricity, reducing vibration and extending service life. Our bushing undergoes heat treatment and precision machining to achieve a consistent hardness profile, guaranteeing repeatable performance across the entire bore range. Additionally, the external key design offers a distinct advantage over conventional bushings by providing a positive drive that resists torque loss under dynamic loads.

FAQ

What is the benefit of the external key?

The external key provides a positive mechanical connection that prevents slippage, allowing the bushing to transmit higher torque without failure.

Can this bushing be used with both metric and imperial shafts?

Yes, the product line includes both metric and inch bore sizes, making it compatible with a wide range of shaft standards.

How does the double‑split barrel improve performance?

The double‑split barrel creates two clamping points, delivering more uniform pressure around the shaft and enhancing load distribution.

Is the solid flange necessary for all applications?

The solid flange is essential when maintaining precise concentricity is critical, such as in high‑speed rotating equipment.

What maintenance is required?

Regular inspection for wear and lubrication according to the equipment manufacturer’s recommendations will ensure optimal longevity.
