VIIPLUS Self-Lubricating Sleeve Bearings: Powering Precision in Forming Machine Tools


Global Leaders in Self-Lubricating Bearings: Where VIIPLUS Stands

The self-lubricating bearing market is dominated by giants like GGB (U.S.), Sankyo Oilless (Japan), and Daido Metal (Japan), which excel in aerospace and automotive sectors. However, VIIPLUS has carved a niche as China’s premier exporter of steel-based self-lubricating sleeve bearings, specializing in heavy industrial applications like forming machine tools. With 57% of its products shipped globally, VIIPLUS combines cost efficiency with engineering excellence to compete on the world stage.


Why Forming Machine Tools Demand Self-Lubricating Bearings

Forming machinery—including forging presses, stamping machines, and hydraulic presses—operates under extreme conditions:

  • High cyclic loads: Repeated impact forces during metal shaping.

  • Heat generation: Friction from continuous operation.

  • Contamination risks: Dust, metal shavings, and lubricant degradation.

Traditional greased bearings fail here due to maintenance demands and contamination. VIIPLUS’s steel-polymer composite sleeve bearings solve these challenges with:

  • Embedded solid lubricants (PTFE, graphite) for zero external lubrication.

  • High load capacity (up to 250 MPa).

  • Corrosion and wear resistance in harsh environments.


Key Applications in Forming Machinery

VIIPLUS bearings are engineered for critical components in metalworking:

Component Function VIIPLUS Solution
Slide Bearing Plates Guide moving parts in frame/open presses Steel-backed bushings with PTFE coating reduce friction by 40% vs. sintered bearings.
Large Gear Bushings Support rotational gears in heavy-duty presses Bronze-steel composites handle 180+ MPa shock loads.
Feeding Mechanism Bushings Ensure precise material alignment Low-friction polymer liners enable ±0.1mm precision.
Hydraulic Press Columns Absorb vertical loads during stamping Multi-layer steel-polymer bearings resist deformation under 200+ ton forces.

VIIPLUS vs. Traditional Bearings in Forming Machines

A comparative breakdown highlights why manufacturers are switching:

Parameter VIIPLUS Steel-Polymer Bearings Traditional Sintered Bearings
Lubrication Self-lubricating (maintenance-free) Requires daily greasing
Load Capacity 200–250 MPa 120–150 MPa
Noise Levels 15–20 dB reduction High vibration noise
Contamination Resistance Immune to dust/debris interference Frequent clogging issues
Lifespan 8,000–10,000 operating hours 3,000–5,000 operating hours

Technical Edge: Materials & Design Innovations

VIIPLUS’s sleeve bearings leverage advanced engineering:

1. Steel-Polymer Composite Structure

  • Base Layer: High-carbon steel for structural rigidity.

  • Intermediate Layer: Porous bronze sintered for lubricant retention.

  • Top Layer: PTFE/graphite blend for ultra-low friction (µ as low as 0.08).

2. Custom Geometry for Forming Machines

  • Flanged designs for axial load support in hydraulic presses.

  • Spherical bushings to compensate for misalignment in stamping tools.


VIIPLUS vs. Global Competitors

While GGB and Daido focus on high-margin sectors, VIIPLUS dominates cost-sensitive heavy industries:

Factor VIIPLUS GGB Daido
Price 30–40% lower Premium Premium
Lead Time 3–5 weeks (custom orders) 8–10 weeks 10–12 weeks
Specialization Forming machines, mining, metallurgy Aerospace, automotive Automotive, robotics
Material Range Steel, bronze, hybrid composites High-performance polymers Aluminum alloys

Case Study: Boosting Efficiency in a Stamping Plant

A German auto parts manufacturer replaced traditional needle bearings in their 2,000-ton stamping press with VIIPLUS’s steel-polymer sleeve bearings. Results included:

  • 50% reduction in unplanned downtime.

  • 25% lower energy consumption due to reduced friction.

  • Zero lubrication costs, saving €12,000 annually.


Future-Proofing Forming Machinery

VIIPLUS is innovating for Industry 4.0 with:

  • Smart bushings equipped with IoT sensors to monitor wear in real time.

  • High-temperature composites (stable up to 350°C) for hot forging applications.


Why Choose VIIPLUS?

  1. Custom Solutions: Tailored materials (e.g., bronze-filled PTFE for high loads) and geometries.

  2. Rapid Prototyping: 3D modeling and CNC machining for bespoke designs.

  3. Global Compliance: Meets ISO 9001, ASTM, and EU RoHS standards.
