Product Overview: The LM78349/10 Tapered Roller Bearing
The LM78349/10 is a single-row inch series Tapered Roller Bearing designed for exceptional performance in applications requiring support for combined radial and axial loads. This versatile bearing set, with a bore diameter of 45.987mm, an outer diameter of 82.931mm, and a total width of 23.812mm, consists of two main separable parts: the cone (inner ring assembly, LM78349) and the cup (outer ring, LM78310). This design simplifies installation, removal, and maintenance procedures. The tapered geometry of the rollers and raceways ensures true rolling motion and low friction, making it a reliable choice for demanding environments, particularly in automotive and industrial machinery. As a key component in our Inch Tapered Roller Bearings collection, the LM78349/10 is manufactured to precise industry standards to ensure long service life and consistent reliability.
Key Features of the LM78349/10 Bearing
- Inch Series Design: Manufactured to standard inch dimensions for compatibility with a wide range of North American and other machinery.
- Handles Combined Loads: Engineered to accommodate high radial and axial (thrust) loads in one direction simultaneously.
- Separable Components: The cone (LM78349) and cup (LM78310) are separable, allowing for easier mounting, dismounting, and inspection.
- Low Friction Operation: The tapered design minimizes rolling friction, which reduces heat generation and energy consumption.
