Product Overview

The FCL Rubber Bush is the elastomer bushing component for FCL pin‑bush flexible shaft couplings. Installed together with coupling pins, it acts as a buffer element for transmission joints, delivering smooth power transmission, vibration damping and shock absorption while compensating minor shaft misalignment. We provide standard‑stock rubber bushes as well as OEM & custom‑molded products according to drawings or samples. For enquiries, please confirm the model number and quantity for accurate quotation.

Key Features & Benefits

• Excellent vibration‑damping & shock‑absorbing performance, reduce mechanical noise and protect equipment
• Good compression‑set resistance for long‑term stable running
• Multiple rubber material grades for oil‑resistant, abrasion‑resistant or high‑temperature working environment
• Easy replacement for on‑site maintenance of FCL pin‑bush coupling
• Full series of standard FCL sizes, support OEM custom hardness, dimension and color
• No lubrication required, low‑maintenance for industrial transmission systems

Material Options

• NBR（Nitrile Butadiene Rubber）: General‑purpose, good oil resistance, most widely used for FCL rubber bush
• CSM / SBR: For anti‑aging, abrasion‑resistant working conditions

Application Fields

Widely applied on pumps, fans, compressors, gear reducers, generator sets and general industrial machinery with FCL pin‑bush flexible coupling. Suitable for medium‑low torque motor drive transmission systems.
