KR-112 Rubber Hose Outer Cover Abrasion Resistance Tester

Additional information

KR-112 Rubber hose friction tester

It is mainly used for rubber hose hose outer cover of abrasion resistance test.

Product Details:

Product Introduction

The KR-112 reciprocating abrasion test instrument is developed strictly following GB/T 12721-2007 and ISO 6945 international standards, dedicated to quantitative abrasion testing on the outer protective layer of hydraulic, pneumatic and industrial rubber hoses. It simulates repeated frictional contact between hose surfaces and external rigid objects in actual service, generating intuitive wear loss data to compare anti-abrasion performance of different rubber cover formulas.
This compact bench tester is widely adopted by automotive hose manufacturers, hydraulic component factories, polymer R&D labs and third-party material certification institutes for raw material incoming inspection, new formula screening and finished product durability verification.

Core Product Advantages

  1. Standard Reciprocating Friction Stroke & Fixed Test Frequency
    Friction travel supports 100mm single-way or full 200mm reciprocating stroke options, locked at standard 1.25Hz oscillation frequency as required by global hose abrasion norms. Constant movement parameters eliminate variable test conditions to guarantee repeatable comparison data across batches.
    2.Modular Weight Combination for Adjustable Test Load

    Supports flexible stacking of standard counterweights from 5N up to maximum 50N total vertical pressure. Operators match load weight based on hose specifications and test standards to replicate different real-world extrusion friction scenarios without custom fixtures.

    3.Stable Low-Vibration Transmission Structure

    Precision crank linkage drive paired with 0.75KW constant-speed motor delivers smooth reciprocating motion with minimal mechanical shake during long-duration continuous testing. The integrated heavy base prevents equipment shifting to maintain consistent friction alignment.
    4.Compact Desktop Layout & Simple Operation

    Small overall footprint occupies limited lab bench space, running on universal single-phase AC220V power supply without special industrial wiring. Digital cycle counter records total friction strokes automatically; operators only need to fix hose samples and set target cycles before unattended testing.

    5.Easy Sample Mounting & Universal Compatibility

    Universal hose clamping fixture fits most common industrial rubber hose sizes. Quick-release design speeds up specimen replacement to improve batch inspection efficiency. Abrasion contact head is detachable for easy sandpaper/media replacement between different test batches.

Standard Test Operation Workflow

  1. Specimen Fixing: Cut rubber hose into standard test length, firmly clamp onto the machine’s dedicated sample holder and lock positioning bolts.
  2. Load Configuration: Stack matched counterweights on the pressure arm to reach the target vertical test load according to test requirements.
  3. Parameter Setup: Set target total reciprocating friction cycles via built-in digital counter. Install standard abrasive paper on the friction contact head.
  4. Automatic Abrasion Test: Start the machine; the friction head reciprocates horizontally at fixed frequency to continuously rub the hose outer surface.
  5. Data Collection: Once preset cycles finish, the machine stops automatically. Remove the hose sample, measure surface wear depth or record mass loss to evaluate outer cover abrasion resistance.
