Our new NEMA 23 R&P PRO line drive spindles feature an integral super oilite bearing and a matched ground shaft (included) for smooth precise motion.

They still provide the same 60 tooth timing pulley for a 3:1 reduction with 20 tooth pulleys or 2.73:1 with 22 tooth pulleys, and are backwards compatible with existing NEMA 23 rack and pinion drive units.
