234413-M-SP

The 234413-M-SP is a premium double-direction axial angular contact ball bearing, specifically engineered to meet the rigorous demands of machine tool spindle applications. Featuring a 65mm bore, 100mm outer diameter, and 44mm width, this unit is built with a robust solid brass cage (M-suffix) that ensures stability even under high-speed rotations. The 60-degree contact angle is a critical design element, allowing the bearing to support significant axial loads from both directions with exceptional rigidity. Whether you are upgrading an existing CNC center or maintaining a high-precision lathe, the SP (Special Precision) tolerance class of this FAG-standard component provides the dimensional accuracy needed to minimize runout and thermal growth during extended operation.

Beyond its structural integrity, the 234413-M-SP stands out for its versatility in lubrication and thermal management. It is designed to work seamlessly alongside NN30 series cylindrical roller bearings to separate radial and axial load support, which effectively extends the service life of the entire spindle assembly. With a limiting speed of approximately 5,600 rpm for grease and up to 7,500 rpm with oil lubrication, it handles high-frequency cycles without compromising on noise levels or precision. This separable, double-row configuration not only simplifies the mounting process but also allows for fine-tuned preloading, making it a reliable choice for industrial environments where downtime is not an option and accuracy is paramount.
