Rexnord 1080-T HUB 2.875 BORE 3 4 X 3 8 KW 0705011 Hub

Rexnord 1080T Hub, 2.875-inch bore, is a standard hub in Rexnord’s T10:T20 grid‑coupling family designed to fit grid‑coupling inserts and connect to a drive shaft in industrial power transmission applications. Identified by part number 0705011, this 1080T model is described on Rexnord’s product pages as 1080T HUB 2.875 BORE and is listed as non-stock, meaning it is not kept in Rexnord’s standard inventory and may be fulfilled through special order channels. As a member of the T10:T20 series, the 1080T hub is designed to pair with the corresponding grid‑coupling insert and companion shaft to form a complete grid coupling assembly for power transmission between shafts in industrial drives. The hub provides a precise 2.875-inch bore to accommodate the shaft and is commonly used in conjunction with Rexnord/Falk grid‑coupling components across motors, conveyors, and processing equipment, where robust, rigid coupling between shafts is required. Availability through multiple distributors is evidenced by references to 0705011 in third‑party listings, including electrical supply catalogs and online marketplaces, which corroborate the model and bore size for this exact hub.
