Peek Trapezoidal Screw Nut for Cleanroom Tools

This Peek Trapezoidal Screw Nut for Cleanroom Tools from Maitu supplier adopts high-purity modified PEEK material, which undergoes strict impurity control during production—with metal and alkali metal content far lower than traditional PEEK materials, as verified by ICP-MS testing conducted by independent laboratories. This material is inert, non-toxic, and resistant to cleanroom cleaning agents and disinfectants, avoiding material degradation or chemical residue leakage. Additionally, we have adopted a lubricant-free, self-lubricating structural design, combined with precision polishing technology, to achieve a surface roughness of Ra ≤ 0.2μm, eliminating particle shedding caused by friction and ensuring silent, smooth operation even during high-frequency, high-precision movements.

Purity & Precision Performance Highlights

- Ultra-High Purity Material & Low Particle Emission: Crafted from high-purity modified PEEK material with strict impurity control, the product has extremely low metal and alkali metal content, as confirmed by ICP-MS testing. It achieves ultra-low particle emission (≤1 particle/ft³ of ≥0.1μm particles during operation), fully complying with ISO 14644-1 Class 1 cleanroom standards. The lubricant-free design eliminates contamination risks from lubricant leakage, which is strictly prohibited in cleanroom environments as per pharmaceutical and semiconductor industry standards.

- Lubricant-Free Self-Lubrication: Adopting a proprietary self-lubricating modified formula, the Peek Trapezoidal Screw Nut for Cleanroom Tools achieves a friction coefficient as low as 0.08-0.24, enabling smooth, silent operation without the need for any lubricants. This not only avoids lubricant contamination of cleanroom air and products but also reduces maintenance frequency, as there is no need to add or replace lubricants—addressing a major pain point of traditional nuts in cleanroom applications.

- Smooth Surface & Anti-Particle Accumulation: Through precision polishing technology, the product’s surface roughness reaches Ra ≤ 0.2μm, creating an ultra-smooth surface that prevents particle adhesion and accumulation. Its integrated sealed structure further blocks external particles from entering the thread gap, avoiding transmission jamming and particle shedding caused by friction, which is critical for maintaining cleanroom purity.

- Chemical & Disinfectant Resistance: The modified PEEK material is highly resistant to common cleanroom cleaning agents, disinfectants, and mild corrosive media, without material degradation, discoloration, or chemical residue leakage. This allows the product to withstand regular cleanroom cleaning and disinfection procedures, ensuring long-term stable performance without compromising cleanroom purity.

- High-Precision Transmission & Dimensional Stability: With a dimensional tolerance of ±0.005mm, the product achieves high-precision fit with the screw, ensuring stable, non-jitter transmission even during high-frequency, micro-movement operations—perfectly matching the precision requirements of cleanroom tools such as semiconductor processing equipment and precision measuring instruments. Its excellent dimensional stability (thermal expansion coefficient of 3.2×10⁻⁵/℃) prevents deformation under cleanroom temperature fluctuations, maintaining transmission accuracy.
