High Quality Auto Engine Parts Pump Mechanical Seal Nonstandard NBR Oil Seal Custom Size,custom Size Oil, Water and Dust Durable
| Common types of oil seals | |||||
| Type | Code number | Main features | Usage | Dielectric pressure resistance | Maximum line speed |
| Simple single lipped | B | It is commonly used for high and low speed rotating shafts and reciprocating movement to seal mineral, oil and water. | Ordinary oil seal, in the case of less dust and impurities, the use of medium pressure, the reciprocating speed of <0.1m/s. | <0.05MPa | 15m/s |
| Regular lip | FB | In addition to the characteristics of the above S type oil seal, dust can be prevented. | Ordinary oil seal, with dustproof lips, dustproof, resistant to medium pressure | <0.05MPa | 15m/s |
| No spring type | BV | Spring free single lip type inner frame type rubber oil seal. | Generally applicable to low-speed conditions, the sealing medium for the lubrication of ester. | <0.05MPa | 6m/s |
| Outer skeleton, single lip | W | With the spring single lip exposed skeleton rubber oil seal, waist thin, follow good, good rigidity. | Ordinary oil seal, used in case of less dust and impurities | <0.05MPa | 15m/s |
| Outer skeleton, double lips | FW | With the lips of the lips exposed, skeleton rubberoil seal, waist thin, followed by good, high stiffness, good coaxial. | Ordinary oil seal, with dustproof lips, dustproof, resistant to medium pressure <0.05 | <0.05MPa | 15m/s |
| Fabricated single lipped | Z | From the inside and outside the outer skeleton oil seal skeleton assembly into piping and installation of high precision, fast heat dissipation, heavy load characteristics. | Suitable for heavy load under high temperature and high speed condition | <0.05MPa | 15m/s |
| Fabricated double lipped | FZ | The assembled external skeleton oil seal with side lip has the characteristics of dust resistance, high installation accuracy, fast heat dissipation and heavy load characteristics. | Apply to high temperature, high speed, heavy load under dust condition | ≤0.05MPa | 15m/s |
| Unidirectional reflux type | Dextral SR,Levo DL | A diagonal bar with angle in lip air measurement system using fluid mechanics principle, produces pump function, with reflux effect. | Because of the backflow effect, the radial force is smaller than that of the ordinary oil seal, thereby reducing wear and heat build-up and improving service life | <0.05MPa | 20m/s |
| Pressure type | NY | The lip is short, stubby waist, with pressure, work pressure is less than 3MPa. | The shaft end oil seal for high pressure pump, general PV value is less than or equal to 8 | ≤3MPa | 15m/s |
Q1: Which Payment way is workable?
A: Irrevocable L/C, Cash, PayPal, Credit card and T/T money transfers. B: 30% T/T deposit in advance, 70% balance before shipment after presentation of ready cargo. C: L/C ( Irrevocable LC at sight: Order amount over USD10,000)
Q2: What is the normal lead time for product orders?
A: Average lead times for prototype / first article are 1-2 weeks, if tooling is involved, lead time for production tooling is 10 days, average production time after sample approval is 2-3 weeks.
Q3: What is your standard packing?
A1:All the goods will be packed by carton box and loaded with pallets. Special packing method can be accepted when needed. A2: We have various rubber compounds approved by UL, AS4020, EN681, EN549, ROHS and REACH.
Q4: How to select the raw compound for my application?
A:With years of experience working with a variety of material, we can help select the material that will best suit your needs while keeping material costs in mind.
Q5: Do you use any international standards for the rubber products? A:Yes, we mainly use ASTM D2000 standard to define the quality of the rubber materials, tolerances as per ISO3302, ISO2768, etc.
Q6: Can you supply different color materials?
A:Yes, we can produce custom molded rubber and silicone rubber products in different colors, the color code will be required in case of an order.
