Timken LM48510 Bearing Kit is a matched tapered-roller bearing set for Caterpillar 093820 (09-3820) applications, combining the outer race LM48510 with the inner cone LM48548 to form a complete countershaft bearing assembly. In Timken catalogs, LM48510 is listed as the outer cup (single race) and LM48548 as the inner cone, with TS (LM48548C / LM48510) and 2S (LM48548-LM48510) configurations offered as bearing kits. This pairing is commonly used in heavy equipment such as Caterpillar tow motors, where tapered roller bearings provide radial and axial load support in a compact package. The Caterpillar 093820 bearing set is marketed by Timken as the LM48548/LM48510 bearing pair for direct replacement in corresponding components.
