Symmetric Stamped Housing Parts

Name: Symmetric Stamped Housing Parts
SKU: 121

Symmetric Stamped Housing Parts by XIAYI stamp shell and cap in mirrored dies, so road load spreads evenly instead of denting one side. The toothed cap bites the base with 3.5 kN of grip — your supplier for housings that stay centered after a million vibration cycles.

Product Description

The Symmetric Stamped Housing Parts kit — a main cylinder shell plus positioning bottom cap — is stamped with wave outer rims and internal radial reinforcing ribs in perfectly mirrored geometry. Symmetry is not styling here: it makes road-vibration load distribute evenly around the full circumference, so nothing dents, nothing warps, and the piston rod stays dead-center for the life of the shock.

Four Structural Details That Do Real Work

Feature	What It Does
Integrated thick radial ribs inside the cylinder	Disperses lateral squeeze from road vibration — no denting, no permanent deformation
Wavy flanged rims on both parts	Expands contact area for even force distribution without warping after assembly
Anti-slip locking protrusions on the bottom cap	Bites the sheet metal base — no sliding or rotation under long-term vibration
Synchronously stamped central through-holes	Unified concentricity fully wrapping the piston rod — no unilateral oil seal abrasion

Durability Proven by Test Bench Numbers

Verification Item	Result
Static anti-slip bite tension	≥ 3.5 kN, no protrusion wear after long vibration
Million-cycle lateral alternating vibration	Ribs crack-free, no permanent deformation
Concentricity drift after endurance test	≤ 0.02 mm
Hot-cold cycling, 1000 cycles −40 ℃ to +110 ℃	No dimensional shift across all seasonal ranges
Zinc coating adhesion	3M tape test passed, no large-area peeling

One-Piece Deep Drawing, No Weld Gaps

Progressive deep drawing eliminates secondary spot welding entirely — there is no weld seam to trap silt and water, no fatigue crack line, and no welding residue to contaminate automatic shock assembly lines. The light hollow structure feeds straight into fully automatic assembly with zero jamming.

FAQ

Q: Our current housings rattle after a year. What is failing?

A: In most returned samples it is the cap sliding — smooth caps rely on friction alone. Our anti-slip protrusions lock into the sheet metal base, and the ≥3.5 kN bite tension is the measured proof.

Q: Can the kit match our automatic assembly line?

A: Yes — wall thickness, concentricity and flange flatness are held to micron-level tolerances with standardized fitting clearance, so the kit feeds through automatic press-fit stations without jamming or interference.

About XIAYI symmetric forming: both shell and cap are stamped on mirrored dies from the same coil batch, so the pair fits as designed — the symmetry you see in the drawing is the symmetry you measure on the line.
