KR‑228 Multi‑Module Pin‑on‑Disc Universal Tribometer & Wear Test System
Multi-Specimen Four Ball Vertical Universal Wear Tester
This machine selects different friction vice forms for testing under certain contact pressure in the form of sliding, rolling, and compound friction so as to evaluate the long-time anti-wear performance of lubricating oil and grease, as well as the friction and wear performance of metal materials.

Product Overview
The KR‑228 modular universal tribology test rig is multi‑purpose laboratory apparatus built for comprehensive friction‑and‑wear characterisation. It supports multiple interchangeable friction‑pair assemblies including pin‑on‑disc, four‑ball, thrust‑washer, ball‑on‑disc and reciprocating‑sliding configurations. Under precisely‑controlled contact‑load, rotational‑speed and temperature conditions, the system assesses anti‑wear property of lubricants & greases, together with tribological behaviour of metals, alloys, surface‑coatings and polymer components.
This stand‑alone unit can deliver real‑time friction‑torque acquisition, automatic friction‑coefficient computation and continuous curve recording for friction‑coefficient‑vs‑time and temperature‑vs‑time datasets. An optional high‑precision wear‑scar measuring module enables direct visualisation, measurement and archival storage of scar geometry on test specimens. Its fixture compatibility matches specimen dimensions used by FALEX‑6 type international reference testers. It complies with ASTM G99, ASTM D3702, ASTM D5183, SH/T 0189‑92, GB/T 12583‑1998 and many other global tribology‑test standards, widely deployed in petrochemical‑lubricant labs, material‑surface‑modification R‑D centres, mechanical‑engineering institutes and accredited third‑party material‑performance‑testing organisations.
Core Product Competitive Advantages
- Rich‑Interchangeable Multi‑Friction‑Pair Fixture Ecosystem
The platform accommodates pin‑on‑disc (single‑pin / three‑pin, large / small disc variants), four‑ball, thrust‑ring‑washer, ball‑on‑disc, ball‑three‑piece assemblies. Up to 10 distinct friction‑pair set‑ups are available; custom‑made non‑standard fixtures can be engineered for special research tasks. Add‑on reciprocating module converts rotary sliding to linear reciprocating wear evaluation.
- High‑Accuracy Force‑Loading & Stable Mechanical Transmission
Incorporates dual‑floating‑bearing, gap‑free guide rail and buffer‑balance mechanical architecture. It provides segmented programmable step‑loading and auto‑loading modes, minimising test‑force deviation. Main spindle is driven by premium‑grade TECO motor paired with P4‑class high‑precision bearings, suppressing vibration interference that would distort wear‑scar morphology during long‑duration cyclic‑sliding experiments.
- Independent Industrial‑Grade Data‑Acquisition Control Architecture
Decoupled embedded industrial controller plus metal touch‑screen human‑machine‑interface; separate signal‑analysis modules insulate measurement channels from mechanical shock and high‑amplitude vibration occurring during coating‑failure events. Full‑digital programmable amplifier completes zero‑point calibration and gear‑switch automatically; test curves can be stored locally or exported for further data‑post‑processing.
- Integrated Precision Temperature‑Controlled Test‑Chamber
Platinum‑RTD temperature sensors deliver accurate thermal regulation ranging from ambient up to 200 °C (260 °C as optional upgrade). Dual‑form heater assemblies (plate‑type and jacket‑type) suit liquid‑lubricant immersion test and dry‑contact high‑temperature friction‑pair scenarios respectively.
- Multi‑Dimensional Automatic Protection & Alarm Logic
Multiple trigger‑conditions for alarm and auto‑halt: manual intervention, preset elapsed‑time, rotational‑cycle threshold, and friction‑torque over‑limit. Once threshold value is breached, equipment terminates test sequence automatically to safeguard specimens, sensors and mechanical assemblies.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Position tribometer on rigid horizontal workshop floor. Verify connection of power‑supply, signal‑cables and cooling‑ventilation. Select and mount target friction‑pair fixture (pin‑on‑disc / four‑ball / thrust‑washer etc.). Install corresponding upper‑and‑lower specimens; add lubricating medium if lubricated‑condition test is required. Set target load, spindle‑speed, test‑temperature, termination‑alarm thresholds and test‑duration via touch‑screen HMI.
- Parameter Pre‑Check
Carry‑out zero‑point calibration for force‑and‑torque measuring channels. Confirm all parameters sit within equipment rated working boundaries. Activate heating function if elevated‑temperature test is needed; wait until thermal equilibrium stabilises.
- Initiate Friction‑Wear Test Sequence
Trigger test‑run command. Spindle drives friction‑pair to perform sliding / rolling / composite‑friction movement. System continuously captures real‑time load, friction‑torque, friction‑coefficient and temperature values, rendering dynamic test‑curves on‑screen throughout the whole experiment.
- Automatic Termination & Data Review
Test stops automatically when reaching preset time / cycle‑count or when friction‑torque exceeds alarm‑threshold. Operators review stored friction‑coefficient‑time and temperature‑time curves. If equipped with wear‑scar‑measurement accessory, inspect and quantify wear‑trace dimension for each specimen. Export raw‑data for lab‑report compilation.
- Post‑Test Tidying
Dismantle test fixtures, take‑off worn‑specimens. Thoroughly clean fixture assembly to remove residual lubricant, metal debris and wear‑particles. Shut‑down heating unit first; after hardware cools down, cut‑off main‑power‑supply. Conduct periodic inspection of sensor calibration status, bearing‑wear and RTD‑sensor performance.
