Product Introduction

The KR-107 digital Akron abrasion tester is standardized lab equipment dedicated to measuring volumetric abrasion loss of vulcanized rubber, elastomer and soft polymer materials. It follows GB/T 1689 national rubber testing standard and simulates real-world surface friction between rubber parts and hard abrasive surfaces under fixed load and tilt angle.
During testing, standard rubber specimens rotate against a calibrated alumina grinding wheel with constant 26.7N vertical pressure. Users weigh samples before and after the preset number of rotations to calculate abrasion index, which serves as core data for new formula screening, raw material incoming inspection and finished product durability certification. This integrated all-in-one machine combines drive, mechanical adjustment and digital control modules, widely adopted in footwear factories, tire manufacturers, auto rubber component plants and accredited material testing labs.

Core Competitive Advantages

  1. Digital Programmable Counter with Auto Stop Function
    Equipped independent digital cycle display panel with start/stop physical buttons. Operators input target abrasion revolutions in advance; the machine automatically cuts off operation once reaching set value and triggers reminder sound, eliminating long-time manual supervision and avoiding test error caused by miscounting rotations.
    2.0–45° Precise Adjustable Inclination Angle

    Large engraved angle dial with clear scale markings allows continuous angle adjustment from 0 to 45°, standard 15° tilt for routine rubber testing. Calibrated scale does not require repeated manual correction after long-term use, ensuring consistent friction contact area for every test batch.
    3.Standard 26.7N Constant Balance Load

    Lever balance weight structure delivers stable 26.7N vertical compression force on specimens throughout full test cycles. No pressure fluctuation during high-speed rotation, perfectly matching international Akron abrasion test load requirements for accurate, repeatable wear data comparison.

    4.Built-In Self-Cleaning Grinding Brush

    Dedicated steel brush assembly automatically sweeps rubber debris off the abrasive wheel while running, preventing powder buildup from blocking the grinding surface and altering abrasion efficiency. It reduces frequent manual cleaning between groups and improves continuous testing efficiency.
    5.Stable Worm Gear Reduction Drive System

    Custom low-noise worm gear reducer matches standard dual-axis differential speeds (76±2rpm specimen wheel, 33–35rpm grinding wheel). Thick cast metal frame with anti-vibration base minimizes mechanical shake during long-hour continuous operation, extending drive component service life.
    6.Complete Standard Matching Abrasive Wheel

    Comes with industry-standard 36# alumina grinding wheel (150×35mm) with dual-side locking fixture to prevent wheel displacement during high-speed friction. Hollow oil injection ports on transmission joints simplify regular lubrication maintenance and reduce wear loss of moving parts.
Control & Angle Details

Standard Complete Test Workflow

  1. Specimen Preparation & Pre-Weighing
    Cut rubber into standard annular test blanks, place under 23℃ constant temperature environment for conditioning, then measure accurate initial weight via precision analytical balance and record data.

 

2.Sample Installation & Angle Setting

Mount specimen tightly on the rubber wheel fixture, rotate angle adjustment handwheel to set standard 15° tilt angle and lock positioning knob.

 

3.Parameter Configuration

Input target abrasion rotation number on digital counter panel, press start button to launch automatic test cycle. The built-in cleaning brush works synchronously to remove rubber debris.

 

4.Automatic Termination

When reaching preset cycles, the machine halts automatically with prompt sound. Remove specimen and brush residual powder completely.

 

5.Post-Test Weighing & Calculation

Reweigh cleaned test piece, compute abrasion volume and abrasion index by weight difference to evaluate material anti-wear performance grade.
