A: It depends.If we have bulk goods in stock, we can ship goods within 3 days after the QC process. If we don’t have stock, normally it takes 7-15 days for OEM samples and 20-30 days for bulk goods. If it refers to opening the new mold, it takes an extra 7-15 days to make the mold.

Snap Rings (Retaining Rings)
Material Options
- Stainless Steel (e.g., SUS304, 316): Corrosion resistance for harsh environments (marine, chemical).
- Carbon Spring Steel (e.g., 65Mn, 1074/1075): High elasticity and fatigue strength; often heat-treated.
- Alloy Steel (e.g., 51CrV4): Enhanced toughness for heavy-load applications (automotive, aerospace).
- Surface Treatments: Zinc plating, phosphating, or passivation to improve wear/rust resistance.
Processing Techniques
- Stamping/Blanking: High-precision die-cutting to shape ring profiles (C-shaped or E-shaped).
- Heat Treatment: Quenching & tempering (HRC 44-55) to achieve optimal hardness and spring properties.
- Grinding/Finishing: Deburring and edge smoothing (Ra ≤0.8μm) to prevent shaft/p bore damage.
- Coating: Electroplating or Dacromet coating for enhanced corrosion protection.
Key Processing Considerations
- Dimensional Tolerance: Strict adherence to ISO/DIN standards (e.g., ±0.05mm on inner/outer diameters).
- Stress Relief: Annealing post-stamping to eliminate internal stresses and prevent cracking.
- Fatigue Testing: Cyclic load simulations (per ASTM E606) to validate lifespan under dynamic conditions.
- Batch Consistency: Automated optical inspection (AOI) for uniform thickness and geometry.
Applications
- Automotive: Securing bearings in transmissions, axles, and engine components.
- Industrial Machinery: Axial fixation of rotating parts (pumps, gears, motors).
- Aerospace: Lightweight retention in landing gear and turbine assemblies.
- Electronics: Miniature snap rings for precision devices (e.g., drones, robotics).
Installation Guidelines
- Tool Selection: Use dedicated snap ring pliers (internal/external) to avoid deformation.
- Alignment: Ensure rings are seated fully in grooves without over-expansion/compression.
- Lubrication: Apply anti-seize grease on high-friction surfaces (e.g., stainless steel rings).
- Inspection: Post-installation checks for proper engagement and no sharp edges.
Frequently Asked Questions
A: Normally, we make a 30% deposit after Pl confirmation and a 70% balance before shipment. lf order amountis too small, we can also change to 100% deposit in order to save bank handling charge.
A: A pre-bulk sample check can solve this problem to the largest extent. We will arrange production according to the pre-bulk sample quality standard after your confirmation of the samples.
A: We are not only a trading company but also a manufacturer. Our factory mainly focuses on mold design and quality inspection. Our bulk production may come from the factories we have worked with for a long time, and they are all ISO9001 certified. Through this cooperation model, we can not only ensure product quality and service, but also satisfy the diversified product needs of customers, and the price is more advantageous.
A: Yes,we are very glad to offer you samples.
However the express courier cost from our company to your required address will be upon your account.
Usually we use DHL, UPS, FEDEX or EMS as the courier.
It will take 3-7 days to arrive many Europe countries and North America.
Which express courier we will use, it’s up to your convenient or the express charge.
