The N25 cylindrical roller bearing without outer ring,inner diameter d is 25 mm,outer diameter D is 37 mm,the width B is 7 mm.

Cylindrical roller bearings without an outer ring are referred to as inner-race-only cylindrical roller bearings. These specialized bearings find use in particular settings, like environments where space constraints exist or unique configurations are necessary. By eliminating the outer ring, these bearings offer enhanced installation flexibility, enabling direct contact with other components to fulfill specific mechanical roles. In various industrial applications, including automotive gearboxes and precision machinery, inner-race-only roller bearings are extensively utilized. Their benefits, such as a compact design, reduced weight, and superior load capacity, make them particularly advantageous in these fields.

This series of products is continuously evolving and advancing in response to growing customer demand.

Applications of Outer Ringless Cylindrical Roller Bearings (or Full Complement Cylindrical Roller Bearings without Outer Rings)

Due to their compact structure, high load capacity, and ease of installation, outer ringless cylindrical roller bearings are widely used in various fields:

Wind Power and Construction Machinery

Primarily used in the drive systems of wind turbines, gearboxes, and construction machinery (such as cranes and excavators). The design without an outer ring prevents sliding failures and simplifies maintenance, enhancing equipment reliability.

Automotive Industry

Applied in critical components like transmissions and differentials, meeting the demands of high-speed rotation and heavy loads. This design optimizes space utilization and reduces mechanical vibrations.

Precision Machinery and Speed Reducers

In planetary gear reducers and optoelectronic instruments, the gear's inner bore directly serves as the outer raceway, achieving structural simplification and space savings. This is especially suitable for precision systems with radial dimension constraints.

Heavy Equipment and Metallurgy

Used in heavy machinery such as steel rolling mills and mining equipment, the double-row full-complement design can withstand significant radial and shock loads, adapting to harsh conditions characterized by high temperatures and heavy loads.

Aerospace and Specialized Equipment

In aerospace hydraulic systems and precision instruments, optimized roller profiles and flange designs enhance axial load capacity and service life, meeting the stringent requirements for high-precision operation.

By eliminating the outer ring, these bearings utilize the host component's bore (such as a gear hole) as the raceway. This reduces the number of parts, lowers friction losses, and achieves higher load density and spatial efficiency. They are particularly suited for industrial applications requiring compact designs and the ability to bear heavy loads.
