Rollers series 315-316

Product catalog summary
Overview: The document details the technical specifications for Rubber Tread Rollers Series 315 and 316, used in conveyor systems to support belts carrying abrasive and sticky materials. These rollers are designed to resist abrasion, aging, and prevent material build-up.
Specifications: The rollers feature a steel base with rubber discs forming an elastic covering. They operate effectively in temperatures from -10°C to +80°C, with special versions available for extreme temperatures and oil resistance.
Design and Usage: These rollers are not intended for use as stretchers. They are designed to prevent material accumulation and are effective in frosty environments. The rubber discs are removable and replaceable, enhancing longevity and maintenance ease.
Special Executions: Custom versions are available with rubber rings for low (-20°C) and high (+120°C) temperatures, oil-resistant rings, and configurations with increased rubber ring numbers.
Designation: The full designation includes the code number, finish, lubrication references, attachment dimensions, and length in mm, with examples like 315005.C14 L608 and 316011.TB.C14 L608.
Technical Data: Detailed tables list roller codes, base idler rollers, bearings, dimensions, and weights, specifying the number of rings and distance pieces for different belt widths and lengths.
Wipper Rollers: These are alternatives to standard rubber tread rollers for supporting return belts in specific conditions, suitable for temperatures between -10°C and +90°C, with special versions for extreme temperatures.
Procedures: The document outlines standard and special execution procedures, specifying working temperature ranges for standard and special rubber rings, including options for low and high temperatures, oil resistance, and increased rubber ring numbers.
Standards and Norms: All dimensions are subject to machining tolerances. The document notes that while drawings and illustrations are accurate, they do not bind the manufacturer to any obligations. DUGOMRULLI reserves the right to modify products without notice.
Recommendations: For abrasive or sticky materials, rubber tread idlers with asymmetrical rubber covering are recommended. Guidance is provided on roller designation, including code numbers, finish, lubrication references, and attachment dimensions.
Key Data from Tables: Tables provide detailed measurements and weights for various roller models, including the number of rings and distance pieces required for different configurations. They also list standard and optional attachment types available for each roller model.
Critical Information: Temperature ranges for roller operation are critical, with standard ranges between -10°C and +90°C, and special executions available for temperatures as low as -25°C and as high as +120°C. The importance of selecting the appropriate roller type based on the material being transported is emphasized.
