Oil Seal Ring
Ma Zhuojia supplies oil seal rings that are used to retain oil and keep out dust in hydraulic and rotary shaft systems. Each unit consists of a nitrile butadiene rubber (NBR) outer sealing element bonded to a steel inner ring for strength. The seals are manufactured in Beijing, China and are intended for automotive shock absorbers, hydraulic cylinders and similar machinery.
The NBR compound typically meets ISO 1817 specifications for oil resistance and can operate from -40 °C to 150 °C. The steel inner ring is usually a carbon‑steel grade that is heat‑treated to a hardness of 45‑55 HRC. Common dimensions range from 10 mm to 30 mm in outer diameter, with a width of 5 mm to 12 mm, although custom sizes can be produced on request. Standard pressure ratings for these seals are up to 10 MPa, which satisfies most OEM requirements in the automotive sector.
Buyers such as original equipment manufacturers, aftermarket distributors and repair workshops frequently order these rings in bulk for assembly lines. Ma Zhuojia states that the price varies between US$0.80 and US$8.00 per piece depending on size and material grade. The supplier offers flexible minimum order quantities and ships the products under CIF terms to major ports. Prospective importers should confirm the exact dimensions, pressure rating and required certification before placing an order.

Sourcing Oil Seal Ring from Ma Zhuojia - China Import Guide
Before confirming an order, verify the exact outer diameter, width and pressure rating required for your equipment. Ask the supplier to provide a dimensional drawing and a material test report that references the NBR grade used. Ensuring these details match your design limits reduces the risk of incompatibility during assembly.
Logistics for Ma Zhuojia typically involve shipment under CIF terms to major Chinese ports such as Shanghai or Shenzhen. While the listing does not state a specific lead time, buyers should request an estimated production schedule and discuss payment terms, which are commonly T/T or L/C. Clarifying incoterms and payment milestones helps avoid unexpected costs.
Importers are advised to arrange a third‑party inspection before loading, focusing on dimensional accuracy, hardness of the steel ring and oil‑resistance performance. Request the inspection report together with the ISO 1817 compliance certificate and the material safety data sheet. These documents provide assurance that the received seals meet the agreed technical standards.
