1. Product Overview 23938EMD1 is double row spherical roller bearing of 239 series. E represents enhanced reinforced internal geometry for higher load capacity; D1 stands for optimized roller and raceway profile for uniform stress distribution; M indicates solid machined brass cage. It features superior self-aligning performance to compensate shaft deflection and mounting misalignment. Capable of bearing heavy radial load and bidirectional axial load simultaneously. Widely
