Spindles
Coating Atomizer
Industry leading spindles in the electrostatic automotive coating industry.
Perfect Atomization. Exceptional Balance.
Coating atomizer spindles demand extraordinary rotational balance to achieve uniform spray patterns and material efficiency. Westwind air bearing spindles provide vibration-free rotation for precision coating applications across automotive, industrial, and advanced surface finishing environments.
With near-zero mechanical contact, the air bearing design delivers ultra-smooth rotation, minimal vibration transmission, and consistent atomisation quality. The result is improved coating uniformity, optimised material usage, and superior surface finish.
Precision rotation translates directly to surface perfection.
Reliability in Demanding Environments
Coating systems often operate in harsh conditions involving solvents, particulates, and fluctuating duty cycles. Air bearing spindles eliminate grease and oil contamination risks while maintaining high-speed stability and thermal consistency.
This non-contact design extends operational life, reduces maintenance intervals, and preserves dynamic balance even under demanding production conditions. Performance remains stable — even when the environment is not.
Engineered for Integration
Compact housing design, optimised airflow management, and robust mechanical construction allow seamless integration into robotic and automated coating systems.
Westwind’s decades of application expertise ensure every coating atomizer spindle is engineered not just for rotational speed, but for long-term process efficiency and system-level stability.

Overview
Features & Benefits
- Low turbine air consumption using industry standard air pressure for economic operation
- Suitable for robotic arm applications due to low mass and small footprint
- High reliability, minimizing down time costs
- Long product life due to non-contacting air bearing design and resistance to intake of external contaminants
- Suitable for water-borne and solvent-based applications
- Efficient turbine design provides fast acceleration and braking for maximum productivity
- Improved atomization due to higher shaft speed.
The D1724 is a compact turbine-driven rotary atomizer with a maximum speed of 70,000rpm and capable of driving bell cups of up to 70mm diameter. Due to its very compact size, it is ideally suited for use in robotic arm spray booth applications and can incorporate electrostatic internally or externally charged bell cup systems.
The shaft nose is suitable for external or internal taper bell cups. Designed for automotive coating applications, the spindle is fitted with a high-efficiency turbine, shaft grounding brushes, integrated shaping air ports and provision for an optical speed sensor system.
