The ServoCity 8mm REX™ Shaft w/ E-Clip (Stainless Steel, 52mm Length) features a unique 8mm REX™ profile, combining an 8mm round and a 7mm hex profile. This design allows compatibility with 8mm round bore bearings and provides a secure drive. Threaded ends facilitate its use as standoffs or dead axles, while the E-clip acts as an end-stop. The shaft extends 3.3mm beyond the E-clip, ensuring proper seating in bearings within 1120 Series U-Channel. The E-clip is removable for versatile application.
