Our range of linear motion shafts combines high-grade materials with advanced chrome plating techniques, ensuring exceptional wear resistance, corrosion protection, and dimensional stability. Kamal Shaft Pvt. Ltd. delivers LM shafts that meet strict industrial standards and cater to diverse operational requirements.

What is an LM Shaft?

An LM shaft (Linear Motion Shaft) is a precision-engineered rod that provides a smooth surface for linear bearings or sliders to glide along a straight path. These shafts are commonly used in systems requiring high-accuracy linear motion, where any deviation can impact the efficiency and lifespan of machinery.

Key features of an LM shaft include:

• Precision Surface Finish: Chrome plating and grinding produce a polished surface to reduce friction and wear.
• High Straightness: Minimal deviation ensures smooth linear movement and alignment.
• Durability: Hardened steel with a chrome layer withstands heavy loads and repetitive motion.
• Versatility: Available in various diameters, lengths, and configurations for multiple industrial applications.

Kamal Shaft Pvt. Ltd., a trusted LM shaft supplier in India, manufactures shafts with chrome plating thickness of 20–25 microns, surface roughness of 0.2 RA, and hardness up to 60 HRC, delivering reliable performance in demanding conditions.

Importance of Hard Chrome Plating

Hard chrome plating provides a protective layer that enhances the durability and efficiency of LM shafts. The benefits include:

• Corrosion Resistance: Protects the shaft from rust and environmental degradation.
• Wear Resistance: Reduces surface wear caused by friction with linear bearings.
• Smooth Operation: Improves sliding performance and minimizes maintenance needs.
• Extended Lifespan: Increases overall durability, reducing the need for frequent replacements.
• Load Handling: Enables the shaft to sustain high loads and repetitive movements without deforming.

By applying hard chrome plating, Kamal Shaft Pvt. Ltd. ensures that linear motion shafts maintain precise dimensions and smooth surfaces throughout their service life.
