The Interchangeable Bearing Roller is a high-quality roller designed for conveyor systems, offering significantly longer service life compared to standard pressed rollers. This roller includes protective components to prevent dust and debris ingress, ensuring smooth operation and enhanced durability.
The interchangeable bearing roller can be manufactured with either used or new bearings, or even higher-quality bearings based on customer requirements. Using higher-grade bearings further increases service life and performance, though it comes at a higher cost compared to standard rollers.
Materials: Available in steel, galvanized steel, and stainless steel.
Types: Pressed, interchangeable, shock-absorbing, or PTFE-coated.
Dimensions: Produced in various diameters and lengths to match conveyor system requirements.
Standard Diameters: 6 mm, 7 mm, and 9 mm (for light, medium, or heavy-duty applications).
Bearings: Bearings are installed on both sides of the roller to provide free rotation, which allows the belt to move smoothly. In interchangeable bearing rollers, the end caps are not welded to the tube, enabling easy bearing replacement in case of failure.
Function: The roller supports the bulk weight of the conveyed material, reducing stress and damage to the conveyor belt. It plays a key role in maintaining conveyor performance and durability.
Shaft Types: Shafts may be threaded or slotted depending on the design.
Wide range of materials: iron, galvanized steel, stainless steel.
Various roller types: pressed, interchangeable, shock-absorbing.
Multiple shaft and bearing options: new or used bearings, threaded or slotted shafts.
Designed to reduce wear and prolong conveyor belt life.
Easy maintenance and bearing replacement without welding.
An interchangeable bearing roller features bearings that can be replaced without damaging the tube. Its service life is 2–3 times longer than pressed rollers, and maintenance costs are up to 50% lower.
SKF bearings can operate continuously for 25,000–30,000 hours, approximately 30% longer than standard Chinese bearings used in some competitors’ rollers.
For heavy-duty applications like iron ore, a 89–108 mm diameter roller with interchangeable bearings is recommended. It supports up to 400 kg load and offers high wear resistance against silica abrasion.
Welded CO2 rollers: Stronger, suitable for heavy loads up to 500 kg.
Pressed rollers: More economical, suitable for light-duty conveyor lines.
Both types are available from Novin CSM.
Standard model: Up to +80°C
HR model: Up to +120°C, ideal for high-temperature environments such as kilns and cement plants.
