What is a 1-fixture bearing?

A 1-fixture bearing is a bearing support designed to hold a rotating shaft in a precise position while allowing it to rotate. This type of bearing is designed with a single mounting point, often a hole or base designed to accommodate a single clamping screw. This configuration offers quick and easy assembly, particularly useful in applications where space is limited and a light fastening is all that's required. The snap ring ensures stable mounting of the bearing, particularly important in constant-rotation applications.

Single-retainer bearings are often used in moderate to high-speed systems , depending on the materials and type of bearing they contain. By design, they can absorb both radial loads (perpendicular to the axis of rotation) and axial loads (parallel to the axis). They are frequently found in industrial applications such as conveyors, machine tools and handling systems. Each model shown specifies the inside diameter in millimeters, enabling a rapid comparison of dimensions, with contents presenting all technical specifications.

What are the applications for 1-fixture bearings?

1-fixture bearings are designed to support drive shafts and associated loads, while guaranteeing smooth, precise rotation. Thanks to their robust design, these bearings ensure optimum shaft support, reducing the risk of misalignment and premature wear.

Whether for high-speed applications or demanding environments, 1-fixture bearings offer a reliable and durable solution. At 123Roulement, we offer a wide range of models to suit various needs, including references from renowned brands such as SKF, INA and RHP. Our bearings are available in different materials, such as cast iron and stainless steel, to meet the specific requirements of each application.

What are the features of 1-holder housings?

Our 1-fixture bearings are designed to support heavy loads, and are fitted with a snap ring for a secure hold. They are available in a range of internal diameter sizes, enabling you to choose the right size for your needs. They are available in a ball-row configuration for optimum absorption of radial and axial loads, ideal for applications such asgears and rollers. What's more, mounting holes vary from model to model, ensuring optimum positioning and stability. Depending on your specific requirements, you'll find models in sheet metal, offering good rigidity and a tight fit , or in stainless steel for greater resistance to extreme conditions.

Benefits and application

1-fixture bearings are particularly well suited to high-speed loads, thanks to their single-track design and solid base. These housings allow fast, precise assembly thanks to their studied center-to-center distance, ideal for applications requiring exact alignment. Our bearings withstand heavy load conditions without the risk of exceeding their tolerances, an essential asset for guaranteeing optimum service life in demanding industrial environments.

We have a large stock of these bearings, with exact quantities available for several part numbers.
