Castor bearing

What are roller bearings?

Roller bearings are essential components in various motion systems. They provide efficient guidance in motion systems, particularly in aluminum profiles. They are used to facilitate the rotation of wheels in applications where a high load and fluid mobility are required. This is made possible by a system of balls or rollers inserted between two rings.

This type of bearing generally consists of a wheel attached to a swivel system that allows 360° rotation, offering great maneuverability. They are found in applications such as carts, furniture and industrial equipment, where they reduce friction and improve the durability of the moving product.

What are the different types of roller bearings?

There are several types of roller bearings (ball, roller, etc.), each designed to meet specific needs in terms of load, durability and operating conditions. The main types include :

• Ball-roller bearings: This type is widely used for heavy loads, as it offers increased strength.

• Swivel bearings: Designed for great flexibility, these bearings allow fast, precise rotation in all directions.

• Aluminum or zinc-plated steel bearings: These materials are ideal for outdoor use, thanks to their protection against rust and corrosion. Some bearings are reinforced with fiberglass for added durability.

• Bearings with integrated fasteners: These models simplify installation and are ideal for applications requiring rapid fastening.

Some product packages include several parts, offering a complete solution for various applications.

Each type has features tailored to different user requirements, whether for heavy loads, outdoor conditions or high precision.

How to choose the right bearing?

To make the right choice of bearing, it's important to consider several factors:

1. Load: Make sure the bearing can support the required amount of load without the risk of premature wear.

2. Environment: For outdoor use, opt for aluminum bearings or those with a zinc-coated finish for their durability.

3. Swivel or fixed: Depending on the application, it may be more advantageous to choose a swivel model for optimum maneuverability, or a fixed model for greater stability. Proper mounting of castors, using appropriate mounting screws, is essential to ensure their smooth operation.

4. thickness and dimensions: Dimensions, such as inner diameter and thickness, must match the profile of the axle or wheel you wish to fit.

How do roller bearings work?

These parts operate by means of a system of balls or rollers inserted between two rings. These balls, arranged in a circle around the wheel axle, reduce friction by facilitating fluid rotation of the wheel on its axle. Mounting screws are often used to secure the castors, ensuring a safe installation. This movement is often assisted by a swivel mechanism, offering omnidirectional rotation. Bearing units are reinforced to offer protection against impact and minimize wear, particularly during intensive use or in demanding conditions.

What are the advantages and disadvantages of roller bearings?

Roller bearings offer a number of advantages:

• Greater mobility: Thanks to their pivoting system, bearings offer smooth maneuverability, ideal for mobile equipment.

• High load capacity: They can support heavy loads, making them a suitable choice for industrial applications.

• Durability: Designed to last, they stand up well to harsh conditions, especially those made of aluminum or zinc-coated steel.

However, they also have their drawbacks:

• Wear: Depending on the environment in which they are used, some materials may wear out more quickly.

• Maintenance: Regular servicing is necessary to prevent dirt build-up and extend bearing life.
