HS Code: 8431390000
The R1800 Series Heavy-Duty Gravity Roller is an efficient and cost-effective material handling solution designed for the transportation of unit loads. It is widely used for moving cartons, containers, drums, tires, and palletized goods, making it an ideal core component for gravity-fed or push-type conveyor lines. This series offers a variety of tube and shaft diameters to fully meet different load-bearing requirements, from light to heavy-duty applications.
Equipped with precision ball bearings, securely sealed within steel-stamped bearing housings, forming a high-strength roller bearing assembly.
Compact and robust construction, with axial load capacity significantly higher than plastic bearing units, ensuring long service life even under heavy-duty conditions.
The steel bearing assembly enables an extremely broad operating temperature range (-30°C to +80°C).
Capable of performing reliably in extreme temperature environments such as cold storage facilities and oven rooms, ensuring stable conveyor system operation.
A full range of tube and shaft diameters, combined with sturdy steel bearing housings, provides outstanding load-bearing performance.
Excels even in demanding, high-intensity industrial environments such as pallet handling.
The bearing housings are pressed into the roller tubes, and the tube ends feature a rounded design.
This unique design allows goods to be easily loaded from the side onto the conveyor line, greatly enhancing operational flexibility and efficiency.
