Overview
The Miller Bearing gravity conveyor roller (model D-3-4-216) is a flanged bearing unit engineered for use in gravity-driven conveyor systems. Miller Bearing Co., Inc. is located in Kent, OH and is a supplier of Conveyor Bearings. This used unit provides efficient, low-maintenance material transportation through passive gravitational motion—ideal for warehouses, distribution centers, and light-to-medium-duty assembly lines where energy efficiency and reliability are priorities.
Key Features
- Flanged bearing design for secure mounting in standard conveyor frame assemblies
- Hardened steel ball and raceway construction for durability in continuous-operation environments
- Low-friction operation reduces power requirements and extends component service life
- Compatible with standard gravity roller conveyor system dimensions and spacing
- Used condition—fully functional and operationally tested
Technical Specifications
Product specifications for the Miller Bearing D-3-4-216 gravity conveyor roller are listed below. For complete bearing geometry (OD, ID, bore type), dimensional drawings, and load ratings, contact your local distributor or Miller Bearing directly at [email protected] or 330.678.8844.
Typical Applications
- Gravity-feed warehouse and distribution conveyor systems
- Manual and automated assembly line material handling
- Package sorting and staging conveyor networks
- Light-to-medium-load product transport (less than 200 lbs per roller)
- Industrial facilities using passive conveyance to reduce energy costs
Compatibility & Replacements
Compatible With
- Standard gravity roller conveyor frame assemblies with 1.5″ to 2″ spacing
- Non-powered conveyor systems operating at speeds below 100 rpm
- Industrial facilities with flanged bearing mounting provisions
- General-duty material handling operations requiring moderate load capacity
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The D-3-4-216 model designation suggests application-specific engineering; compatibility with other Miller Bearing models or competitor bearings must be confirmed by bearing geometry (outer diameter, inner bore, flange dimensions) and load requirements.
Works With
- Standard gravity conveyor frame rails and bearing housings
- Modular conveyor system components from major material handling manufacturers
- Axle and tube assemblies meeting gravity roller industry standards
