Overview
The Fairlane RR-250-35-EX10 finned roller shaft mount is engineered for conveyor systems, material handling equipment, and manufacturing assembly lines. This finned-groove roller features a 2.5-inch diameter (63.5 mm) neoprene surface bonded to a steel insert, with a shaft-mount hub design and dual set screws (90 degrees apart) for secure, tool-free installation. The EX10 designation indicates 10 fins—grooves that reduce surface contact and allow dirt, debris, and liquids to pass freely, extending wear life and improving system reliability.
Key Features
- 2.5-inch (63.5 mm) outside diameter with finned, grooved surface pattern
- 35-durometer neoprene elastomer (shore A hardness rating)
- Steel insert core for rigidity and load-bearing stability
- Shaft-mount configuration with hub extending past the roller body
- Two precision set screws (90-degree spacing) for quick, repeatable shaft mounting
- Pre-lubricated precision ball bearings for smooth, quiet operation
- Low-marring, non-abrasive contact surface suitable for gentle product handling
- Lot of 2 units (new, no-box condition)
