Vacuum Pump Coupling Metal Parts
Shenzhen Yujiaxin Tech Co., Ltd manufactures vacuum pump coupling metal parts that link motor shafts to pump rotors while compensating for misalignment. The components are offered in stainless steel grades 304 and 316, carbon steel 45 #, and aluminium alloy, providing options for corrosion resistance and strength. These couplings are engineered to maintain leak‑free operation in industrial vacuum systems.
Stainless steel 304 delivers typical tensile strength of 520 MPa and corrosion resistance in humid environments, whereas 316 adds superior resistance to chloride attack. Carbon steel 45 # is a standard low‑alloy steel with typical yield strength around 250 MPa, suitable for cost‑sensitive applications. Aluminium alloy versions are lighter, with typical density 2.7 g/cm³ and tensile strength near 150 MPa. Industry standards such as DIN 740 and ISO 281 specify the dimensional accuracy and runout tolerances, commonly ±0.02 mm.
These couplings are widely used by vacuum pump manufacturers, equipment integrators and maintenance service providers in sectors including electronics, pharmaceuticals and food processing. Importers generally request the parts in bulk, packed in reinforced cardboard boxes with protective inserts. While the listing does not state a minimum order quantity, buyers should clarify the required batch size, Incoterm and payment schedule with the supplier. Lead time and pricing are negotiated on a case‑by‑case basis.
| Materials offered | Stainless Steel 304, Stainless Steel 316, Carbon Steel 45 #, Aluminium Alloy |
| Typical torque capacity | typical 150 Nm for 30 mm bore versions |
| Typical operating temperature | typical - 20 °C to 200 °C for stainless steel, - 30 °C to 150 °C for carbon steel |
| Standard compliance | standard DIN 740 and ISO 281 |
| Dimensional tolerance | typical ±0.02 mm on key dimensions |
| Typical surface roughness | typical Ra 1.6 µm after machining |
| Typical packaging | standard reinforced cardboard boxes with foam inserts |
| Typical weight | typical 0.5 - 3 kg per coupling depending on size |
| Typical hardness | typical 170 HB for stainless steel 304 |
| Typical shaft alignment tolerance | typical 0.01 mm |
Shenzhen Yujiaxin Tech Co., Ltd is located at 11/F Building A, Xing He Century Building, Caitian Road, Futian District, Shenzhen, Guangdong Province, China, postal code 518038. The company carries a harbor trust tier, confirming its verified business registration, though its platform response metrics show a 0 percent response rate and no recorded response time. Yujiaxin specialises in precision metal machining and production of vacuum pump coupling components.
The product listing specifies material options and mentions compliance with DIN and ISO standards, but it does not disclose production capacity, lead times or unit pricing. Prospective buyers should request a detailed quotation that includes the applicable standards certificates, delivery schedule and payment terms. No further corporate history or client references are provided.
Vacuum pump coupling metal parts are precision-engineered components designed to transmit torque between motor and pump shafts while accommodating angular, parallel, and axial misalignment in vacuum systems. These couplings are widely used in industrial vacuum pumps, HVAC systems, and laboratory equipment, requiring high dimensional accuracy and material integrity to maintain vacuum integrity. As critical import components for vacuum pump manufacturers and maintenance suppliers, these parts are specified by standard norms such as DIN and meet strict tolerances for leak-free, reliable operation.

Sourcing Vacuum Pump Coupling Metal Parts from Shenzhen Yujiaxin Tech Co., Ltd - China Import Guide
Before committing to purchase, importers should confirm that the selected material - stainless steel 304, 316, carbon steel 45 # or aluminium alloy - matches the required corrosion and strength properties. Request a material test report and verify that the couplings meet DIN 740 dimensional standards and the typical torque capacity of 150 Nm where applicable.
Shipments from China are commonly arranged under FOB or CIF Incoterms. Buyers need to agree on the preferred Incoterm, obtain a freight quotation and decide on payment terms such as T/T against a pro‑forma invoice or a confirmed letter of credit. Because lead times are not listed, a clear production schedule should be established before the purchase order is issued.
Upon arrival, quality assurance should include visual inspection for surface defects, dimensional verification against the ±0.02 mm tolerance, and hardness testing to confirm the typical 170 HB value for stainless steel parts. Suppliers can provide mill test certificates and compliance statements with DIN 740. Engaging a third‑party inspection service before loading can help ensure that the couplings satisfy the required specifications and reduce the risk of non‑conforming goods.
