Product Description
SKF 30311 is a single row tapered roller bearing with a 55 mm inside diameter and 120 mm outside diameter, featuring a shielded end type and manufactured from high-grade steel with a pressed steel cage. This bearing is designed to handle combined radial and axial loads efficiently.
The tapered raceways converge at a common point on the bearing axis, allowing true rolling motion which reduces frictional forces and enhances service life. The contact angle optimizes the axial load capability.
The bearing supports a limiting speed of 5600 rpm, making it suitable for demanding rotating machinery and industrial applications, including construction, manufacturing, and mechanical power transmission systems.
The separable design comprises an inner ring (cone) and outer ring (cup), allowing for easy installation, removal, and inspection. This also facilitates precise preload adjustments and rigid bearing arrangements when installed with a matching tapered roller bearing.
The pressed steel cage offers robustness under dynamic loads and helps maintain roller position, while the shield prevents ingress of dust and debris, enhancing operational reliability.
The pressed steel cage ensures durable and stable operation. The shielded design offers protection against contaminants. Steel bearing material provides strength and long service life. Limiting speed rating of 5600 rpm for high-speed applications.
Tapered raceways for reduced friction and improved load handling. Separable cone and cup for simplified maintenance and mounting.
