In high-stakes industries where reliability and efficiency are critical, VIIPLUS DIN 1494/ISO 3547-compliant sliding bearings stand out as a cornerstone of performance. Engineered for durability and versatility, these self-lubricating bushings are tailored for construction, marine, agriculture, and more. This article dives into their design principles, material innovations, and application-specific advantages—supported by data-driven insights, technical comparisons, and actionable guidance.
VIIPLUS leverages powder metallurgy to create porous structures that store and release lubricant dynamically. Here’s how it works:
Porous Matrix: Bearings are sintered to create microscopic oil-retaining pores (10–30% porosity).
Thermal Activation: As temperatures rise during operation, oil viscosity drops, allowing lubricant to seep out and form a protective film.
Capillary Action: Post-operation cooling draws oil back into pores, ensuring sustained lubrication.
Key Benefits:
Maintenance-free operation even in remote or inaccessible environments.
Reduced friction, wear, and energy consumption.
VIIPLUS offers a range of materials optimized for specific challenges:
| Material | Properties | Best For | Standards |
|---|---|---|---|
| Bronze (CuSn8) | High wear resistance, corrosion-proof | Hydraulic systems, marine environments | DIN 1494, ISO 3547 |
| Steel-Backed PTFE | Extreme load capacity (200+ MPa) | Heavy machinery, mining equipment | ISO 3547 |
| Sintered Iron | Cost-effective, moderate loads | Agricultural machinery, conveyor belts | DIN 1494 |
| Stainless Steel 316 | Corrosion resistance (H₂S, saltwater) | Offshore rigs, chemical processing | ISO 3547 |
VIIPLUS provides tailored solutions across industries:
| Bushing Type | Design Features | Applications |
|---|---|---|
| Straight Sleeve | Cylindrical, no flange | Conveyor rollers, automotive suspensions |
| Flanged Sleeve | Integrated axial support | Pump housings, gearbox assemblies |
| Thrust Washers | Flat, low-profile | Rotary tables, agricultural pivots |
| Split Bushings | Easy installation/removal | Repair-friendly systems (e.g., marine shafts) |
Maximize lifespan by optimizing these critical parameters:
| Factor | Impact | Optimal Range | VIIPLUS Advantage |
|---|---|---|---|
| Load (P) | Higher load = accelerated wear | ≤150 MPa (dynamic) | Steel-backed PTFE handles ≤250 MPa |
| Speed (V) | Increased speed = higher friction | ≤1.5 m/s | Porous bronze reduces heat buildup |
| PV Value | Lower PV = longer lifespan | ≤1.5 N/mm²·m/s | Lubricant film minimizes PV stress |
| Temperature | >120°C degrades lubricants | -40°C to +180°C | High-temp oils stable up to 240°C |
| Surface Roughness | Ra >0.8 µm accelerates wear | Ra ≤0.4 µm (shaft) | Pre-machined to Ra 0.2–0.8 µm |
Formula:
Where = Load (N/mm²), = Speed (m/s).
