Industrial Strip Key 6×20×2000mm – Precision Machine Shaft Key for Power Transmission

Product Overview

The Industrial Strip Key 6×20×2000 mm is a high-precision, robust shaft key designed to transmit torque between rotating machine elements and shafts without slippage. Fabricated from premium alloy or carbon steel material, this long strip key is ideal for heavy machinery, gearboxes, pulleys, couplings, and other power transmission assemblies.

With exact tolerances and consistent cross-section (6 mm height × 20 mm width), it ensures tight fitting in keyways, minimizing backlash and wear. The 2000 mm length can be cut to size for custom needs, making it versatile for a wide range of industrial applications. Whether it's in metallurgy, mining, machine fabrication, or heavy equipment repair, this strip key offers dependable performance and longevity.

Key Features

• Accurate Dimensions & Tolerances – Precisely manufactured to 6 × 20 × 2000 mm with minimal deviation.

• High Strength Material – Made from high-grade alloy or hardened steel for durability and fatigue resistance.

• Cut-to-Length Flexibility – The full 2000 mm bar can be cut to any required length to suit your assembly.

• Parallel / Sunk Key Style – Designed to fit standard keyways in both shaft and mating hub.

• Minimal Backlash & Wear – Good fit reduces micro-movement and fretting in keyed joints.

• Consistent Cross-Section – Uniform cross-sectional area ensures predictable torque capacity.

• Corrosion-Resistant Finish (if applicable) – Surface treatment like plating or coating to resist oxidation.

• Industrial Grade Quality – Meets mechanical and dimensional standards for demanding applications.

• Wide Compatibility – Can be used with gears, couplings, pulleys, sprockets, flywheels, etc.

• Long Service Life – Engineered to resist fatigue, shear, and wear across repeated duty cycles.

Technical Specifications

Application & Benefits

• Reliable Power Transmission — Prevents relative rotation between shaft and hub by creating a positive mechanical interlock.

• Custom Lengths — You can cut the 2000 mm key to your exact needs, reducing waste and enabling flexibility.

• Reduced Wear & Backlash — Accurate fit in keyways helps reduce fretting, vibration, and loosening over time.

• Versatile Use — Ideal for industrial machines, motors, pump drives, conveyors, and other rotating assemblies.

• Safety & Protection — A properly sized key can act as a sacrificial element, failing before more expensive components do.

• Standard Fit Compatibility — Works with commonly used keyway standards, fitting many existing hubs and shafts.
