Now HONGLEI starts to operate their SNS, you can contact us through the following ways: Collage, Facebook, Linkedin, YouTube, Twitter.

Wholesale market

It's worth visiting a wholesale market where you can browse through a huge range of products at very low prices. For example, the Yiwu market is the largest wholesale market in the world. Unlike a trade fair, it is a physical store where you can check out items and take them with you, or ship them to your warehouse in the US.

Merchandise is readily available, so you can see exactly what you are getting and gauge the quality of the product by physically inspecting it. You will need to make some effort here to remove any counterfeit products and fake brands.

Request samples

Once you have contacted a potential supplier, either online or at a trade show, you will need to request samples of the items you are interested in via . Most suppliers will send you product photos or catalogs for free, but it is difficult to judge the quality of the items from the photos.

Ideally, you will receive a test sample of the product to verify its quality. You may have to pay for the samples, but it is usually a small investment for your peace of mind.

Have a down payment ready

Most suppliers expect you to deposit some money up front, usually about 30%, and pay the balance when the item is ready to ship. Most suppliers won't even look at your order until the down payment is wired to their account. honglei has years of experience trading and we export to many countries, so you can trust our service and speed of delivery.

Preparing for shipping

Sea freight is five to six times cheaper than air freight, which is essential if you are importing large quantities of goods. Navigation is also complicated if you don't know what you are doing. Importing goods by air or sea requires a lot of documentation, such as commercial invoices, packing slips and bills of lading to clear customs, and you may have to pay customs duties on your imports.

Also known as grease seals, rotary shaft seals, or fluid seals, oil seals play a pivotal role in mechanical equipment. They are often overlooked because they are a small part of the machine, but when these oil seals fail, the consequences can be huge, like seal leakages that are costly to fix.

From assembly machines to car engines, oil seals prevent any harmful damage from occurring, which is why you must choose the right oil seal with the highest quality. There are many kinds of oil seals, all of which have several uses.

This article will guide you through the most common factors you should look for when buying oil seals to help you choose the right one for the machinery you&#;re working on.

11 Factors to Consider When Buying Oil Seals

Improper installation and poor-quality oil seals are some of the reasons that pieces of machinery get damaged. When choosing an oil seal, consider the following factors.

1. Temperature

The temperature range of the seal elastomer should match the temperature range of where you&#;ll install the seal. For example, high-temperature and high-pressure environments need more durable rubber, like Viton. If the oil seal is exposed to extreme temperatures outside of the elastomer&#;s range, the sealing lip may harden, break, and crack.

2. Material

The oil seal&#;s material matters, as it can determine how well it performs depending on its use. Sealing elements can come in leather, silicone, synthetic rubber, Viton, nitrile, and polyacrylate. Nitrile is good for general purposes, as it&#;s flexible and resistant against oils, hot water, and gasoline. However, it doesn&#;t do well in extremely high temperatures. Meanwhile, silicone oil seals lessen wear and tear by absorbing lubricants. They have a wide temperature range and high thermal resistance, too.

3. Pressure

Understanding the compression requirements of your components is important. Most ordinary oil seals are designed for very low-pressure applications (about 8 psi or less). If the intended application has high pressure, you should consider choosing an oil seal ideal for high pressure or changing to a pressure-free structure.

4. Shaft speed

The oil seal shouldn&#;t suffer from spiraling or abrasions. As such, you should consider the maximum allowable shaft speed, runout, type of oil seal material, type of fluid being sealed, and housing bore and shaft concentricity before buying an oil seal.

5. Shaft and bore tolerances

Close shaft and bore tolerances should be present if you want the best seal performance. It would be best to consider the shaft&#;s vibration, eccentricity, and end play.

6. Concentricity

You must align bore and shaft centers because misalignment can shorten the oil seal&#;s life cycle due to the excessive wear concentrated on only one side of the sealing lip.

7. Runout

It would be best if you kept runout to a minimum. When the center of rotation moves, it&#;s usually caused by a shaft whip or bearing wobble. When you add misalignment, then you&#;ll face a greater problem. Contrary to common practice, installing flexible couplings won&#;t correct misalignment, which is why you need the right oil seal to prevent all these issues from arising.

8. Quality

The quality of the oil seal affects its service life. The higher the quality, the longer the lifespan, reducing wear and tear and increasing your ROI through lower maintenance costs. While wear and tear issues are inevitable, you should mitigate them by using materials that last long. Here, the first step to ensuring quality oil seals is purchasing from a reputable oil seal supplier.

9. Shaft hardness

When shafts have a Rockwell (RC) hardness of 30 or more, you can expect the oil seal to have a longer seal life. For shafts exposed to more abrasive contamination, your oil seal should handle RC 60.

10. Shaft surface finish

You can tell that you have effective sealing if the shaft surface finish is in excellent condition. Sealing performance is greatly influenced by the spiral lead and the direction of the finish tool marks.

You&#;ll get the best sealing results when the shafts are ground or polished with concentric (no spiral lead) finish marks. If the shaft can&#;t help but have spiral finish leads, they should lead toward the fluid when the shaft rotates.

11. Lubricant

Oil or lubricants play a significant role in improving the oil seal&#;s performance. You should choose a lubricant compatible with the seal lip elastomer material and the right viscosity for the application. Incompatible lubrication can result in the wearing out of the oil seal.

An example of a lubricant you can use is Permatex Anti-Seize Lubricant, a highly refined blend of graphite, aluminum, and copper lubricants.

Choose the Correct Oil Seal for Your Needs

Oil seals come in various sizes, styles, and materials. Hence, it can be challenging to pick the right type for your needs.
