Stainless Steel Brake Pistons
This precision-machined part is designed for applications requiring stable performance, reliable alignment, and long service life. Manufactured from CRES 303 stainless steel per ASTM A581/A582, this component is suitable for assemblies where durability and corrosion resistance are essential. Its structure and machining quality make it an excellent fit for systems that use Stainless Steel Brake Pistons or similar precision cylindrical components.
Product Features
● Premium CRES 303 Stainless Steel
The piston is produced from corrosion-resistant stainless steel, offering stable mechanical properties in industrial, motion-control, and braking applications. Its material strength and machinability make it a dependable option for brake assemblies and precision mechanisms.
● Passivated Surface (ASTM A967)
The surface is fully passivated to improve corrosion resistance, ensuring cleanliness and long-term functionality. This finish is commonly used in high-performance hardware, including Stainless Steel Brake Pistons and hydraulic system components.
● Precision CNC Machining
All edges are deburred to .003–.015, and fillet radii are controlled within .005–.020, resulting in smooth transitions and consistent mating surfaces. Diameters sharing a common axis maintain a runout tolerance of .010, ensuring accurate alignment in braking or mechanical assemblies.
Product Construction
The piston features a solid stainless-steel cylindrical body with a precision-machined front recess designed to support a bearing or mating element. The inner bore is concentric with the outer diameter to maintain smooth rotational or linear movement. Fillet radii and edge breaks are applied throughout the structure to reduce stress concentration and improve durability. The overall construction delivers a stable, rigid part that matches the performance needs of modern Stainless Steel Brake Pistons and other high-precision assemblies.
