Product Description

The 30x42x7 Precision Seals is a high-performance industrial component designed for precision applications requiring tight dimensional tolerances and reliable mechanical performance. Engineered to operate within a wide temperature range of -40°C to +150°C, it integrates seamlessly with 30x42x7 Mechanical Shims and High-Tolerance 30x42x7 Rings in complex assemblies, typically used in automotive, aerospace, and advanced manufacturing systems. With an exact 30x42x7mm profile and ±0.005mm radial clearance tolerance, this seal accommodates axial loads up to 15kN while maintaining alignment stability. Compatible with hydraulic, pneumatic, and rotary systems, it features corrosion-resistant materials for extended service life in harsh environments. Key advantages include vibration damping and thermal stability, though installation requires specialized tooling for optimal compression. The design excels in high-pressure interfaces, supporting dynamic sealing for shafts up to 50mm diameter.
