Overview
The 1630RS idler sprocket with internal ball bearing is a compact tension and guide assembly for #60 ANSI roller chain applications. The 1630RS bearing designation indicates a standard deep groove ball bearing with sealed contact (RS = sealed on both sides), integrated into the sprocket hub to provide smooth, low-friction operation. This unit features a hardened steel sprocket body with 11 teeth, designed for light to medium load industrial automation, material handling, and conveyor systems.
Key Features
- Deep groove 1630RS ball bearing with dual seals for protection against contaminants
