6238 M Bearing Product Overview & Core Advantages
The 6238 M is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered to primarily handle radial loads, it is characterized by its high precision, robust construction, and suitability for high-speed operation. Manufactured to a P6 tolerance class, this bearing ensures precise running accuracy and high operational reliability, making it an ideal choice for machinery requiring superior rotational performance and dimensional stability.
Model Code Breakdown
- 6238: Basic model number denoting a single row deep groove ball bearing with a 190mm bore and 340mm outside diameter.
- M: Designates that the bearing features a machined brass cage (also known as a pressed brass cage). This cage type offers high strength, excellent guidance, and is suitable for high-speed applications and demanding operating conditions.
6238 M Bearing Structural Features & Performance Benefits
The design of the 6238 M delivers distinct performance advantages:
- High-Speed Capability: The combination of the machined brass (M) cage and an open design facilitates efficient lubrication and heat dissipation, contributing to its high limiting speed of 3,400 rpm.
- Robust Load Capacity: With a high dynamic load rating of 57,326 lbf and a static load rating of 62,947 lbf, this bearing is built to withstand significant radial forces, ensuring long service life under heavy loads.
- Precision Performance: Conforming to P6 tolerance class and a standard CN radial internal clearance, it provides precise shaft guidance, reduced vibration, and consistent operation in precision machinery.
- Durable Construction: Components made from chrome steel for the rings and balls, along with a stainless steel cage, provide excellent resistance to wear and corrosion, enhancing the bearing's overall durability.
6238 M Bearing Typical Application Areas
The 6238 M bearing is widely used in various industrial sectors due to its reliability and performance. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
