1/2 in. Rigid Plastic Insulating Bushing (4-Pack)

Description

Product Overview

The Halex 1/2 in. Rigid Plastic Insulating Bushing is engineered to provide superior electrical insulation while maintaining the mechanical strength required for demanding linear motion applications. Manufactured by Halex Company, a trusted name in industrial components, each bushing is molded from high‑grade rigid plastic that resists abrasion, chemical exposure, and temperature fluctuations. The 4‑Pack configuration ensures you have a ready supply for multiple shafts or for replacement stock, reducing downtime and inventory complexity.

Designed specifically for 1/2‑inch shafts, the bushing features a precision‑machined inner diameter that guarantees a tight, slip‑free fit, eliminating play that could lead to premature wear. The outer diameter and length are optimized to fit standard linear motion housings, making installation straightforward without the need for additional adapters or tooling. With a weight of only 0.634 ounces per unit, the bushings add minimal mass to moving assemblies, preserving system dynamics and efficiency.

Key specifications include a part number 27520, package dimensions of 2 × 1.2 × 0.07 inches, and compliance with industry standards for insulating materials. The product’s best‑seller rank of #51 in Linear Motion Bushing Shafts highlights its popularity among engineers and maintenance professionals seeking reliable, cost‑effective solutions. Its durability and ease of use make it a preferred choice for a wide range of applications, from CNC machines to conveyor systems.

Beyond the core functional attributes, the bushing’s design incorporates a smooth surface finish that minimizes friction, extending the life of both the bushing and the shaft it protects. The rigid plastic composition also provides excellent resistance to moisture ingress, a critical factor in environments where corrosion could compromise performance. This combination of electrical isolation, mechanical resilience, and user‑friendly installation sets the Halex bushing apart from competing metal or composite alternatives.

Overall, the Halex 1/2 in. Rigid Plastic Insulating Bushing delivers a balanced solution that addresses the electrical, mechanical, and operational demands of modern industrial equipment. Its compact packaging, reliable performance, and brand reputation make it an essential component for any maintenance inventory focused on longevity and safety.

Usage

This bushing is ideally suited for applications where electrical isolation is paramount, such as in motorized linear actuators, robotic arms, and precision positioning systems. It can be installed in environments ranging from cleanroom facilities to heavy‑duty manufacturing floors, providing consistent performance regardless of ambient conditions. The lightweight nature of the plastic material ensures that the added mass does not affect the dynamic response of high‑speed mechanisms.

Installation is a simple press‑fit process: align the bushing with the shaft, apply even pressure, and the inner diameter will expand slightly to accommodate the shaft, creating a secure, vibration‑resistant connection. No additional fasteners or adhesives are required, which reduces installation time and eliminates potential points of failure. The bushing’s resistance to oil, coolant, and other industrial fluids makes it a versatile choice for equipment that operates under lubricated or wet conditions.

Maintenance crews appreciate the ease of replacement; the 4‑Pack ensures that spare parts are on hand, allowing for quick swaps during scheduled downtime. Because the bushing does not conduct electricity, it also serves as a protective barrier against stray currents that could otherwise cause premature wear or damage to sensitive electronic components attached to the moving assembly.

Typical use cases include: linear guide rails in CNC milling machines, pneumatic cylinder shafts, and conveyor belt rollers where insulation prevents electrical interference. The bushing’s robust construction also makes it suitable for outdoor installations, such as agricultural equipment or construction machinery, where exposure to dust, moisture, and temperature extremes is common.

FAQ

What material is the bushing made from and is it suitable for harsh environments?

The bushing is molded from a high‑grade rigid plastic that offers excellent resistance to abrasion, chemicals, oil, coolant, and temperature variations. This makes it well‑suited for harsh industrial settings, outdoor applications, and environments where moisture or contaminants are present.

Can this bushing be used on shafts larger or smaller than 1/2 inch?

The bushing is specifically designed for a 1/2‑inch shaft diameter. While it may accommodate slight variations due to the material’s slight flexibility, using it on significantly larger or smaller shafts could result in improper fit, reduced insulation performance, or premature wear. For other shaft sizes, we recommend selecting a bushing with the appropriate inner diameter.

How does the electrical isolation property benefit my equipment?

Electrical isolation prevents stray currents from traveling along the shaft and reaching other components, which can cause corrosion, interference, or damage to sensitive electronics. By using this insulating bushing, you protect both the mechanical parts and the electronic control systems, extending overall equipment lifespan.

Is installation tool‑free, and what steps should I follow?

Yes, installation is tool‑free. Align the bushing with the shaft, apply even pressure, and the inner diameter will expand slightly to create a secure press‑fit. No adhesives or fasteners are required. For best results, ensure the shaft surface is clean and free of debris before installation.

What warranty and support does Halex provide for this product?

Halex offers a limited warranty covering manufacturing defects for a specified period after purchase. In addition, our technical support team is available to assist with installation guidance, compatibility questions, and any troubleshooting you may need throughout the product’s lifecycle.
