Industrial L16WL20W Wedge

Sunnen L16WL20W Wedge is a Sunnen replacement wedge used in honing mandrel assemblies to keep the honing stone in plane during bore finishing. In Sunnen's replacement-part literature, wedges are listed for the BL20 family, with the BL20 wedge (LN-3692A) and related L20/L20W configurations referenced as a wedge option for this system. Sunnen notes that wedge wear directly affects accuracy: "Wedge and wedge guide wear: Once a wedge or wedge guide begins to show wear, it no longer can keep the stone flat," signaling that replacement is required to preserve bore geometry. The L16WL20W designation fits within Sunnen's BL20/L20 wedge family, and these wedges are used with Sunnen mandrels to support stone shoes and maintain stone alignment during honing, contributing to consistent bore finish. Catalog materials show related parts like Stone Retainers (LN-3218A) and Wedge Guides, underscoring the wedge's role as a wear-prone, replaceable component in production honing setups. Typical applications include precision bore finishing and sizing on Sunnen honing units that use BL20/L20 configurations, where maintaining a flat honing surface is key to achieving the intended bore diameter and roundness.
