Hydraulic Bearing vs Dual Ball Bearing (Pros and Cons)

When it comes to choosing a hydraulic bearing or a dual bearing for your applications, it’s important to understand the pros and cons of each. In this post, we’ll take a closer look at both types of bearings and help you decide which one is right for you.

What is a Hydraulic Bearing?

A hydraulic bearing is a type of bearing that uses pressurized oil to lubricate and support the load. The pressurized oil is typically supplied by a pump, which can be either electric or manual. Hydraulic bearings are often used in high-load applications where conventional bearings would fail. The average life of hydraulic bearings is 40000-50000 hours.

What are dual ball bearings and how do they work?

Dual ball bearings are a type of bearing that has two ‘balls’ inside the housing. They work by having two balls in the center of the bearing. These balls are connected to each other and turn around an axle that runs through the middle of the housing. One ball is on one side of the axle and one ball is on another side, but they always stay close together. The bearings help reduce friction in your machine, which makes it run smoother and last longer. Dual ball bearings are often used in applications where high speeds and precision are required, such as motors and turbochargers.

Pros of hydraulic bearings

1. Hydraulic bearings offer a more consistent, smoother movement and are therefore often used in heavier-duty or higher-speed applications.
2. Hydraulic bearings are not subject to the same level of fluctuation because their viscosity does not change due to temperature, pressure, or altitude changes as much as a dual ball bearing system does.
3. Hydraulic bearings also tend to give out less noise during operation.

Cons of hydraulic bearings

If you are looking for increased durability, a hydraulic bearing might not be the best option. They generally do not last as long as a dual ball bearing because of the reliance on oil to lubricate it. If the oil supply is interrupted, there will be immediate and irreversible damage to the bearings. 

Another disadvantage is the potential for leakage when using this type of bearing due to its reliance on an external supply of incompressible fluid, although some designs have been shown to have a low enough leak rate so as not to cause significant problems.

Pros of dual ball bearings

There are several benefits to using a dual ball bearing in your applications. First, they tend to be more durable than hydraulic bearings. This means they can withstand higher loads and speeds without failure. Second, they require less maintenance than hydraulic bearings. This is because there are no seals or lubricants to replace. Finally, dual ball bearings are typically more precise than hydraulic bearings. This means they can provide smoother operation and better performance in demanding applications.

Cons of dual ball bearings

There are a few key disadvantages to using dual ball bearings in your applications. First, they are not as resistant to high temperatures as hydraulic bearings. This means that they may not perform as well in applications that require high operating temperatures. Second, dual ball bearings are also less resistant to shock and vibration than hydraulic bearings. This means that they may not be the best choice for applications that subject the bearing to high levels of shock and vibration. Finally, dual ball bearings tend to be more expensive than hydraulic bearings.

Hydraulic Bearing vs Dual Ball Bearing (Summary)

Hydraulic bearings and 2 ball bearings are two types of bearings that are commonly used in industrial applications. Both types of bearings have their own advantages and disadvantages, hence understanding the difference between them before deciding which one to use in a particular application is crucial.

Hydraulic bearings rely on a pressurized fluid to support the load, while dual bearings have two rows of rolling elements that support the load. Hydraulic bearings are typically less expensive than dual bearings, and they offer higher load capacity and better shock resistance. Dual bearings are more commonly used in applications where space is limited, such as in electric motors.

A hydraulic bearing provides a smoother operation with less wear and tear than a dual ball bearing. However, it does not provide the same level of load capacity as the dual ball bearing. A dual ball bearing can handle heavier loads than a hydraulic bearing but has a higher chance of failure. The choice of which type to use will depend on what you are using your equipment for and how much weight it will need to hold up.
