RAParts LO95/L090 Rubber Spider Insert L-095 & L090 Fits Lovejoy Martin L-Jaw Coupling

Description

Product Overview

The RAParts LO95/L090 Rubber Spider Insert is engineered to meet the demanding requirements of modern industrial power transmission systems. Constructed from premium NBR (Nitrile) rubber, the spider insert delivers exceptional resistance to oil, fuel, and chemical exposure while maintaining flexibility and durability under high‑torque conditions. With a precise 2 1/8″ outer diameter, the component fits seamlessly into standard L‑Jaw couplings, ensuring a tight seal that eliminates backlash and vibration.

Designed as a direct replacement for the original part number L095NBR, this aftermarket spider insert provides identical dimensions and performance characteristics, allowing for effortless retrofitting in existing equipment. The product dimensions of 5 × 5 × 5 inches and a lightweight 1.6 ounces make handling and installation straightforward, reducing downtime during maintenance cycles. The inclusion of a robust NBR compound ensures long‑term elasticity, preventing premature cracking or hardening even after extended exposure to harsh operating environments.

Usage

Ideal for a wide range of applications, the RAParts spider insert excels in environments where reliable torque transmission and shaft protection are critical. It is commonly employed in conveyor systems, mixers, crushers, and other heavy‑duty machinery that rely on flexible couplings to absorb shock loads and misalignment. The insert’s compatibility with popular brands such as Lovejoy, Martin, Browning, TB, and Woods makes it a versatile choice for OEMs and maintenance professionals alike.

When installed, the rubber spider acts as a dampening element, reducing noise and vibration while safeguarding the connected shafts from wear caused by metal‑to‑metal contact. This protective function extends the service life of both the coupling and the driven equipment, delivering cost savings through reduced part replacements and lower maintenance intervals. The product is also suitable for use in agricultural, mining, and construction equipment where exposure to dust, moisture, and temperature fluctuations is routine.

FAQ

What size couplings is this spider insert compatible with?

The insert is designed for L‑Jaw couplings with a 2 1/8″ outer diameter, fitting popular models from Lovejoy, Martin, Browning, TB, Woods, and other manufacturers that use the same specification.

Can this spider insert be used in high‑temperature environments?

Yes. The NBR rubber compound is formulated to retain its elasticity and strength up to temperatures of approximately 120 °F (49 °C), making it suitable for most industrial temperature ranges.

Is the product a direct replacement for the original OEM part?

Absolutely. It replaces part number L095NBR and matches the original dimensions and performance characteristics, allowing for a seamless swap without any modification to the coupling housing.

How does the rubber spider improve equipment longevity?

By acting as a flexible buffer, the spider reduces vibration and shock transmission between connected shafts, which minimizes wear on bearings, seals, and the coupling itself, ultimately extending the service intervals of the entire drivetrain.

What warranty or guarantee does RAParts provide?

RAParts offers a limited one‑year warranty covering material defects and workmanship. Should any issue arise within this period, we will replace the part at no additional cost, reinforcing our commitment to quality and customer confidence.
