Schaeffler Roller Bearing, 25mm Inside Diameter, 37mm Outside Diameter - RNA4904-XL


This roller bearing is a high-performance needle roller bearing designed to accommodate varying load capacities in machinery. With an inside diameter of 25mm and an outside diameter of 37mm, it offers a race width of 17mm. This unit is characterised by its open-end type for ease of installation and maintenance, making it suitable for diverse mechanical applications.

Features & Benefits


• Dynamic load rating of 23700 N enhances performance reliability

• Operating speeds of up to 9900 rpm for efficient operation

• Fatigue limit load of 4700 N offers durable performance under stress

• Designed for parallel bore usage ensuring precise fitting

• Constructed from sheet steel for robust resistance to wear

Applications


• Used for precision machinery in automation industries

• Ideal for electrical equipment requiring high-speed rotation

• Suitable for mechanical systems needing reliable load distribution

• Can be applied in manufacturing lines with rigorous working conditions

How does the static load rating affect performance in machinery?


A high static load rating of 25500 N indicates this bearing can support heavy loads without structural failure, making it ideal for applications demanding durability and strength under stationary conditions.

What are the implications of the limiting speed specifications?


With a limiting speed of 16900 rpm, the bearing is capable of functioning efficiently in high-speed applications, ensuring operational effectiveness while minimising friction and heat generation.

What are the benefits of using a needle bearing in my assembly?


Needle bearings, like this model, offer a larger load-carrying capacity while conserving space, making them suitable for compact assemblies where traditional bearings are impractical.

How do I ensure the longevity of the bearing in high-speed applications?


Regular lubrication and adherence to the specific speed ratings can help maintain this bearing's performance in high-speed environments, reducing wear and extending its operational life.
