GIRTON BG19B Plastic Raceway Hex Bearing 1-1/2 Tube x 1/2 Shaft – 3388

The Girton BG19B is a plastic raceway hex bearing designed for linear motion applications with a 1-1/2 inch tube and 1/2 inch shaft. It is commonly used in medical equipment assemblies where smooth, low-friction linear travel is required—such as positioning stages, cable guides, and articulating support arms. The plastic raceway construction minimizes noise and vibration while reducing maintenance requirements compared to metal bearings.
