Product Overview

Core Competitive Advantages

1. Multi-Standard Calibrated Constant Load System
   Comes with interchangeable counterweight blocks to realize 2.5N, 7.5N and 10N standard test loads (10N ±0.2N nominal load). The vertical pressure structure maintains steady downward force throughout the full 40m abrasion stroke, eliminating pressure deviation caused by loose fixtures to guarantee consistent comparative test data across batches.
   2.Digital Preset Counter with Auto Stop Function

   Independent LED digital counting panel supports preset total rotation cycles (84 revolutions for standard 40m travel). Once reaching the set value, the machine automatically cuts power without manual monitoring, effectively avoiding human counting errors and improving continuous lab testing efficiency.

   3.Precision Gear Horizontal Displacement Mechanism

   6-teeth per inch lead screw drives the specimen holder to move 4.2mm per drum rotation, evenly distributing friction traces on the sandpaper surface to prevent localized over-wear of abrasive cloth and extend sandpaper service life, lowering daily consumable costs.
   4.Integrated Compact Low-Noise Framework

   Low-power 100W reduction motor delivers stable drum rotation at 40±1 RPM with minimal vibration. The whole machine adopts high-temperature electrostatic baking paint housing, stainless transmission gears and wear-resistant sliding parts, featuring a compact desktop footprint that fits all standard lab benches.
   5.Easy Maintenance & Replaceable Consumables

   Quick-release sandpaper fixing structure allows operators to swap abrasive cloth in minutes. A dedicated cleaning brush is included to sweep rubber debris after each test, preventing powder buildup that interferes with subsequent friction tests. All moving joints are reserved with oil injection holes for convenient regular lubrication.
   6.Full Compliance with Global Test Specifications

   One machine covers footwear, tire, conveyor belt and general rubber abrasion test requirements, matching GB/T 9867, GB/T 20991, DIN 53516, ISO 4649 and SATRA TM standards, fully meeting third-party laboratory certification testing demands.

Standard Complete Test Workflow

1. Specimen Preparation & Pre-Weighing
   Cut raw materials into standard Φ16mm cylindrical samples, place under standard 23℃ lab environment for conditioning, then record precise initial weight via analytical balance.
2. Sandpaper & Load Setup
   Wrap qualified 60# abrasive paper evenly around the 150mm drum and fasten both ends; install matched counterweight to reach required test load.
3. Specimen Mounting
   Fix the conditioned test piece firmly on the sliding specimen holder to ensure full vertical contact with the sandpaper surface.
4. Parameter Programming
   Input standard 84 rotation cycles on the digital counter, press the start button to launch automatic abrasion cycle.
5. Automatic Termination & Post-Processing
   The machine halts automatically after completing 40m friction travel. Remove the specimen and brush off all rubber powder residue completely.
6. Data Calculation
   Reweigh the cleaned sample, compute abrasion volume or weight loss to evaluate the material’s wear resistance grade for formula comparison and quality filing.
