    Rolling Contact Bearings As Compared To Sliding Contact Bearings Have

    Contact bearings are a common component in many machines and equipment, and for good reason. They provide smooth and reliable movement. However, there are two main types of contact bearings: sliding and rolling. Rolling contact bearings are becoming increasingly popular because they offer several benefits that are hard to beat. In this blog article, we will compare rolling contact bearings to sliding contact bearings and outline their respective advantages and disadvantages.

    What are Rolling Contact Bearings?

    Rolling contact bearings are a newer type of bearing that use two balls instead of one. The balls make contact at an angle, which keeps the bearings from rolling. They’re usually used in applications where stability is important, like elevators and roller coasters. Sliding contact bearings work better in applications where speed is more important, like cars and bikes.

    What are Sliding Contact Bearings?

    Sliding contact bearings are a type of bearing that use sliding surfaces to move the bearing components relative to one another. This type of bearing is often used in applications where high speed or heavy loads are applied, as it offers better performance than rolling contact bearings. Sliding contact bearings also have several advantages over rolling contact bearings, including: they are less likely to experience wear and tear, they are easier to maintain, and they offer greater flexibility when it comes to mounting options.

    When choosing a sliding contact bearing for your application, it important to keep these advantages in mind. Forinstance, if your application requires high speeds or heavy loads, choose a sliding contact bearing that is made from high quality materials. Similarly, make sure your chosen sliding contact bearing is easy to maintain by ensuring that the mounting hardware is durable and easy to replace.

    What are the Differences Between the Two Types of Bearings?

    Rolling contact bearings are the most common type of bearing in use today. They have a small inner ring and a large outer ring that move together as the bearing spins. This movement causes the bearings to rotate on their axes, which allows them to move smoothly along an axis without any friction.

    Sliding contact bearings work somewhat differently. There is a small inner ring that moves relative to an outer ring that stays stationary. The two rings interact with each other as they move, which creates friction and causes the bearing to rotate around its own axis.

    How Do Rolling Contact Bearings Work?

    Rolling contact bearings have a number of benefits over sliding contact bearings, the most notable of which is that rolling contact bearings do not require lubrication. Sliding contact bearings can become slicker over time and require a periodic application of oil or grease to keep them in good working order. Rolling contact bearings also have a longer life due to their lack of wear.

    Another benefit of rolling contact bearings is that they are less likely to become jammed. This is because the ball bearing can move freely within the cylindrical race, avoiding the possibility of the ball becoming stuck. Jamming can lead to reduced performance and even failure of the Bearing.

    In terms of weight, rolling contact bearings are generally lighter than sliding contact bearings. This is due to the fact that rolling contacts do not require any additional components (such as lubrication) to operate properly.

    What Are the Advantages of Roller Contact Bearings?

    Roller bearings are typically more robust and less prone to contamination than sliding bearings. Roller bearings are also faster to speed up and slow down, making them ideal for high-speed applications such as motors and pumps. Finally, roller bearings offer a variety of other advantages including smoother running, longer life, and resistance to thermal shocks.

    What Are the Disadvantages of Rolling Contact Bearings?

    While rolling contact bearings offer many advantages over sliding contact bearings, they also have several disadvantages. The main disadvantage of rolling contact bearings is that they are less tolerant to misalignment and can therefore experience more wear and tear. Additionally, rolling contact bearings often require a greater amount of lubrication than sliding contact bearings, which can add to their maintenance costs.


    Rolling contact bearings have many properties that make them desirable in applications such as automotive and industrial machinery. Among these properties are their ability to resist wear and tear, their high speed capability, and the low noise levels they produce. Sliding contact bearings, by contrast, are used in applications where a minimal amount of wear and tear is desired, such as consumer goods.
