Material Options for Bearing Shields (YX SHIELD)

*The information contained herein are typical values intended for reference and comparison purposes only. They should NOT be used as a basis for design specifications for quality control.

Cold-Rolled Steel (CR Steel / SPCC, DC01)

Properties
Smooth surface and tight dimensional accuracy with stable mechanical strength—well suited for deep drawing and precision forming of bearing shields.

Advantages

Cost-effective for high-volume production
Excellent formability and consistent tolerances
Accepts secondary finishes (oil, zinc, paint) easily

Typical Applications
Standard dust shields for general-purpose bearings in appliances, motors, and industrial equipment.

Processing Notes
Best choice for prototype-to-mass production. Requires corrosion protection (e.g., oil, zinc plating, paint) for humid environments.

Electro-Galvanized Steel (SECC)

Properties
Uniform electro-zinc coating on CR steel delivers improved corrosion resistance with an even, paint-friendly surface.

Advantages

Smooth, consistent appearance; excellent paint adhesion
Better rust protection than bare CR steel
Reliable formability for deep drawing and forming

Typical Applications
Shields for general machinery, automotive interiors, and indoor industrial environments needing enhanced cosmetic quality.

Processing Notes
Coating is thinner than hot-dip; for harsh environments, pair with paint/phosphate. Compatible with most stamping lubricants and post-finishes.

Tinplate (SPTE / TFS)

Properties
Steel substrate with a thin tin (or chrome) layer offering baseline corrosion resistance and a smooth, bright surface.

Advantages

Balanced cost and protection vs. plain CR steel
Good drawability and consistent surface finish
Suitable for decorative or visible components

Typical Applications
Shields for home appliances, office equipment, and light-duty bearings in low-to-moderate humidity.

Processing Notes
Tin layer can scratch—use protective packaging. Additional clear oils or lacquers can improve handling and corrosion resistance.

Stainless Steel (304 / 430)

Properties
High corrosion resistance and strength; maintains performance in humid, chemical, or temperature-cycling environments.

Advantages

Superior rust protection without additional coatings
Good durability and dimensional stability
Clean appearance; suitable for hygiene-sensitive uses

Typical Applications
Shields for food/medical equipment, outdoor devices, chemical plants, and coastal or wash-down environments.

Processing Notes
Formability is lower than CR steel—recommend optimized dies and controlled drawing/forming parameters. Brushed (#4) surfaces may change appearance after forming.
