Hey there! As a supplier of Bearing 6008, I often get asked about the different kinds of seals these bearings have. So, I thought I'd write this blog to share all the info I've got on this topic.
First off, let's talk a bit about Bearing 6008 itself. It's a pretty popular bearing used in a whole bunch of applications. You can check out more details about it here. This bearing is widely used in various industries like household appliances, internal combustion engines, transportation vehicles, agricultural machinery, and construction machinery.

Now, let's get into the main topic - the seals of Bearing 6008. There are several types of seals available, and each has its own unique features and benefits.
Open Type (No Seal)
The open type of Bearing 6008 doesn't have any seals at all. This might seem a bit odd at first, but there are actually good reasons for using it. In applications where there's a clean environment and the bearing doesn't need protection from contaminants, an open bearing can work just fine. It also allows for easy lubrication as there are no barriers. However, it's not suitable for dirty or wet environments because dirt, dust, and moisture can easily get into the bearing and cause damage.
Z Type (Single Metal Shield)
A Bearing 6008 with a Z - type seal has a single metal shield on one side. The metal shield is designed to keep out larger particles like dust and debris. It's a bit more protective than the open type. The shield is usually made of steel and is attached to the outer ring of the bearing. This type of seal is great for applications where there's a moderate amount of dirt in the environment. But it's not completely dust - tight, and it doesn't offer much protection against moisture.
2Z Type (Double Metal Shields)
The 2Z type of Bearing 6008 comes with double metal shields, one on each side. This provides better protection compared to the Z - type. The double shields can prevent more dirt and debris from entering the bearing. It's commonly used in applications where the environment is a bit dirtier, but still not extremely harsh. For example, in some light - duty industrial machinery, the 2Z - sealed Bearing 6008 can work well. However, like the Z - type, it's not very effective against moisture.
RS Type (Single Rubber Seal)
The RS type has a single rubber seal on one side. Rubber seals are much more effective than metal shields when it comes to keeping out contaminants. The rubber creates a tight seal against the inner ring of the bearing, preventing dust, dirt, and even some moisture from getting in. This type of seal is often used in applications where there's a risk of exposure to water or other liquids. For instance, in some agricultural machinery that might be exposed to rain or irrigation water, an RS - sealed Bearing 6008 can be a good choice.
2RS Type (Double Rubber Seals)
The 2RS type is the most protective of all. It has double rubber seals, one on each side of the bearing. This provides maximum protection against dirt, dust, and moisture. It can be used in very harsh environments, such as in construction machinery that operates in muddy or dusty conditions. The double rubber seals ensure that the bearing's internal components are well - protected, which can significantly extend the bearing's lifespan.
When choosing the right seal for your Bearing 6008, you need to consider the operating environment. If it's a clean and dry environment, an open or Z - type bearing might be sufficient. But if there's a lot of dirt, dust, or moisture, you'll probably want to go for an RS or 2RS type.
Another thing to keep in mind is the lubrication. Sealed bearings usually come pre - lubricated, and the seals help to keep the lubricant inside the bearing. This reduces the need for frequent relubrication. However, in some cases, you might still need to relubricate the bearing, especially if it's operating under heavy loads or high - speed conditions.
