VIIPLUS Custom Self-Lubricating Bearings: Powering Automotive Innovation with Dual Mass Flywheel Technology
The automotive industry is undergoing a silent revolution, driven by the demand for lighter, quieter, and maintenance-free components. VIIPLUS, a global leader in engineered self-lubricating bearings, is at the forefront of this transformation. With over 50 self-lubricating bushings now integrated into modern passenger cars—replacing traditional needle and sintered bearings—VIIPLUS solutions are redefining automotive efficiency.
At the heart of modern vehicle power transmission systems lies the Dual Mass Flywheel (DMFW), designed to reduce vibrations and enhance drivetrain smoothness. VIIPLUS’s self-lubricating bearings play a pivotal role here, ensuring seamless performance under extreme conditions.
In a DMFW clutch system, two flywheels are connected by a flanged, oil-free sliding sleeve bearing. This bearing must accommodate:
Axial sliding: Absorbing engine torsional vibrations.
Radial movement: Compensating for misalignment during operation.
Traditional rolling bearings fail here due to high wear and lubrication demands. VIIPLUS’s DU Cylindrical Bushes, however, excel with:
Self-lubricating solid films: Eliminating the need for external grease.
High wear resistance: Extending component lifespan.
Lightweight design: Reducing rotational inertia for fuel efficiency.
The superiority of VIIPLUS’s plain bearings over rolling bearings is evident in critical metrics:
| Parameter | DU Cylindrical Bushes (VIIPLUS) | Traditional Rolling Bearings |
|---|---|---|
| Lubrication | Self-lubricating (zero maintenance) | Requires frequent greasing |
| Noise Levels | Ultra-low vibration & noise | Higher NVH (noise, vibration, harshness) |
| Durability | Resists wear under high cyclic loads | Prone to pitting and fatigue failure |
| Weight | 30–40% lighter | Bulkier design |
| Cost Efficiency | Lower lifetime maintenance costs | Higher servicing expenses |
This contrast explains why automakers are rapidly adopting VIIPLUS bearings in DMFW systems, achieving up to 80% replacement rates in variable speed drives and compressors.
VIIPLUS’s custom bearings are engineered for diverse automotive subsystems:
Gear Shift Bushings: Reduce friction in manual and automatic transmissions.
Torque Converter Bushings: Enhance durability in high-torque environments.
Control Arm Bushings: Improve ride comfort with noise-dampening properties.
Steering Column Bearings: Ensure precise, low-maintenance operation.
Turbocharger Bushings: Withstand extreme temperatures and rotational speeds.
Throttle Valve Bushings: Provide smooth, reliable actuation.
VIIPLUS prioritizes sustainability without compromising performance. Their lead-free bearings, made from stainless steel woven fabric and textile fibers, address environmental concerns while delivering:
Toxicity-free operation: Compliant with global regulations (e.g., REACH, RoHS).
Enhanced corrosion resistance: Ideal for electric vehicles (EVs) and hybrid systems.
Customization Expertise: Tailored material blends (e.g., bronze composites, polymer-coated steel) for specific load and temperature requirements.
R&D-Driven Design: Advanced testing simulates real-world conditions, from -40°C to 300°C.
Global Supply Chain: Rapid prototyping and scalable production from their Jiashan County hub.
A leading European truck manufacturer replaced traditional needle bearings with VIIPLUS’s DU bushings in their DMFW systems. Results included:
40% reduction in maintenance costs.
15% longer component lifespan.
3% improvement in fuel efficiency due to reduced rotational mass.
As electric vehicles (EVs) and autonomous driving technologies advance, the demand for lightweight, noise-free, and maintenance-free bearings will surge. VIIPLUS is already innovating for these markets, with:
Composite bushings for EV battery cooling systems.
Ultra-low friction bearings for autonomous vehicle actuators.
VIIPLUS offers end-to-end support, from material selection to component geometry optimization. Their global export footprint, with 57% of production shipped overseas, underscores their reliability.
