Product Description
SKF 1303 ETN9 self-aligning ball bearing is a two-row bearing with a 17 mm bore diameter and 47 mm outside diameter, designed to accommodate angular misalignment between shaft and housing in automation and electrical equipment. It features non-metallic cage material and steel balls with an open end configuration for easy maintenance access.
This bearing is engineered to provide enhanced load distribution and stability due to its two-row design. The non-metallic cage reduces operating friction and noise, which is beneficial for continuous and high-speed operations. Its cylindrical bore requires shafts to be plain-fitted for proper installation.
The bearing’s CN internal clearance allows for precise axial and radial shaft movements while maintaining performance. With a dynamic load rating of 12.7 kN, it offers strong fatigue resistance, and a static load rating of 3.4 kN enables the bearing to withstand stationary loads during downtime.
The open-end type construction permits direct inspection and convenient lubrication access, simplifying routine maintenance. The limiting speed of 20,000 rpm suits applications such as motor and drive assemblies, precision fans, spindles in electronics manufacturing, electrical actuators requiring angular compensation, and rotating joints in mechanical handling equipment.
