KML Bearing USA’s Spherical OD Deep Groove Radial Ball Bearings feature Metric spherical outer diameters that are effective in self-aligning applications. These spherical OD ball bearings are designed to fit in standard self-aligning pressed steel or cast iron applications where set screw or eccentric shaft lock is not required, or in areas where space is limited. Each spherical OD ball bearing will generally fit in the corresponding series cast iron or stamped steel housing; for example, CS207DDU fits in a PE207 Pillow Block.
These Spherical OD Metric Single Row Deep Groove Radial ball bearings are produced to ABEC 1 Classification and are available with industrial grade 2RS double seals. The industrial grade sealed Spherical OD Deep Groove Radial Ball Bearings feature dual-lip non-contact seals on both sides. (Shown on the PDF in Documents & Materials.) Although KML Bearing USA’s Spherical OD ball bearings are standard as double sealed bearings, there are a few industrial grade shielded sizes that feature metal shields on both sides: CS203DDU, CS204DDU, CS205DDU and CS207DDU (pictured on this page).
Featuring the same construction as KML Bearing USA’s Metric Single Row Deep Groove Radial ball bearings, the inner ring, outer ring and balls are produced using vacuum degassed 52100 bearing steel. After production, they are heat treat hardened to produce a durable wear surface on the balls and ball tracks. All ball retainers and shields are manufactured from cold rolled steel.
Similar to other Single Row Deep Groove (SRDG) ball bearings, KML Bearing USA’s Spherical OD ball bearings are lubricated with Chevron SRI#2 from the factory. As a high temperature ball and roller bearing grease, it’s formulated using a synthetic poly urea ashless organic thickener with additional rust and oxidation inhibitors. As such, this grease provides protection in severe applications, harsh environments and where incidental contact with both salt and fresh water may occur.
