RAParts Jaw Coupling Hub L095 X 1/2 Lovejoy Style with Keyway and Set Screw

Description

Product Overview

The RAParts Jaw Coupling Hub L095 X 1/2 Lovejoy Style is engineered to deliver precise torque transmission while minimizing vibration and wear. Constructed from high‑strength steel, the hub provides a robust platform for flexible spider couplings, ensuring consistent performance even under heavy load conditions. The 1/2 inch bore accommodates a wide variety of shafts, and the 1/8 inch keyway offers a secure locking interface that resists slippage. Designed to replace original equipment manufacturer (OEM) parts, this hub matches the dimensions of popular Lovejoy, Martin, Browning, and TB models, making it a versatile upgrade for existing installations. The inclusion of a set screw allows for quick, tool‑free adjustments, reducing downtime during maintenance. With a compact 5 x 5 x 5 inch footprint and a weight of just one pound, the hub integrates seamlessly into tight mechanical assemblies while delivering the durability required for industrial environments.

Usage

This hub is ideally suited for a range of applications where reliable power transfer is critical. Typical use cases include conveyor systems, packaging machinery, material handling equipment, and any automated process that relies on precise rotational motion. The Lovejoy‑style design ensures compatibility with existing flexible spider couplings, allowing engineers to retrofit older machines without extensive redesign. In harsh industrial settings—such as factories with high temperatures, dust, or exposure to chemicals—the steel construction and secure keyway provide resistance to corrosion and mechanical fatigue. Installation is straightforward: align the hub with the shaft, insert the key, and tighten the set screw to lock the assembly in place. The hub’s low profile also makes it an excellent choice for portable equipment and mobile units where space and weight constraints are paramount.

FAQ

What shaft sizes are compatible with this hub?

The hub features a 1/2 inch bore, making it compatible with shafts ranging from 0.500 to 0.525 inches in diameter. It is designed to work with standard industrial shafts commonly found in conveyor and packaging equipment.

Can this hub be used with non‑Lovejoy couplings?

Yes. While the hub is optimized for Lovejoy‑style flexible spider couplings, its universal keyway and set screw design allow it to interface with many other coupling brands that share the same dimensions, such as Martin, Browning, and TB.

How do I install the set screw correctly?

First, align the hub on the shaft and insert the key into the keyway. Then, tighten the set screw by hand until it is snug, and finish tightening with a torque wrench to the manufacturer’s recommended specification (typically 5‑7 Nm). This ensures a secure lock without over‑tightening.

What warranty does RAParts provide?

RAParts offers a one‑year limited warranty covering material defects and workmanship. If you encounter any issues within the warranty period, contact our support team for a replacement or repair solution.

Is bulk ordering available for this hub?

Yes. We provide volume discounts and kit options for customers needing multiple units. Please reach out to our sales department for pricing and availability details.
