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.
DIN 471 Retaining Ring
Shaft Retaining Ring (Outer Circlip)
Material:
- Typically made of spring steel (e.g., 65Mn, 60Si2Mn) or stainless steel (e.g., AISI 304/316) for elasticity and corrosion resistance.
- Surface treatments: zinc plating, black oxide coating, or phosphating to enhance durability and rust prevention.
Manufacturing Process:
- Stamping/Punching: Precision cutting from steel sheets to form the ring shape.
- Heat Treatment: Tempering and hardening to achieve required spring properties.
- Surface Finishing: Coating application (e.g., electroplating) for corrosion resistance.
- Deburring: Smoothing sharp edges to prevent installation damage.
Key Processing Points:
- Dimensional accuracy (inner/outer diameter, thickness) must align with DIN/ISO standards.
- Consistent elasticity and hardness post-heat treatment.
- Edge quality to avoid stress concentrations during use.
Applications:
- Axial fixation of bearings, gears, shafts, or pulleys in machinery.
- Automotive transmissions, industrial equipment, and precision instruments.
- Prevents component displacement in housings or bores.
Installation:
- Use specialized pliers (internal circlip pliers) to compress the ring into the groove.
- Ensure the bore diameter and groove dimensions match the ring specifications.
- Avoid over-expanding the ring to retain elasticity and prevent permanent deformation.
- Verify secure seating in the groove after installation.
Standards: Compliant with DIN 472 (hole rings) and ISO 8752, often paired with DIN 471 (shaft rings) for comprehensive axial retention solutions.
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.
