Maintenance-free plain bearing bushings are suitable for linear and rotary motion. Movement is ensured by gliding. Thus, no rolling components are necessary, as with a rolling bearing.
Plain bearings can be selected in various shapes, materials and sizes . Bearing bushings are also already available integrated into the housing to make assembly easy and convenient.
Maintenance-free plain bearings have the benefit of not requiring maintenance or only little maintenance due to their integrated lubrication properties. This means that an external lubrication system can be omitted, which would not only require extra installation space, but is often very costly.
In contrast to rolling bearings, gliding bearings can generally accommodate high load-bearing capacities due to the larger contact area and require reduced installation space. The service life of the plain bearing bushings must be calculated depending on the application, since various influencing variables, such as roughness, stroke or rotational speed, have an influence on the service life.

Plain Bearing Bushes with Flange: Engineering Excellence for Maintenance-Free Motion Solutions

Introduction

Plain Bearing Bushes with Flange represent a pinnacle of innovation in motion control technology. Engineered for both linear and rotary applications, these maintenance-free bushings eliminate the need for rolling components, relying instead on precision gliding mechanics. Ideal for industries where reliability and space efficiency are paramount—such as automotive, industrial machinery, and robotics—they deliver exceptional performance without compromising on longevity or operational simplicity.

Key Features & Technical Advantages

1. Diverse Material Portfolio for Customized Performance

• Self-Lubricating Composites:
  
  • Sintered bronze and copper alloys embedded with graphite ensure consistent lubrication POM (polyacetal) variants offer ultra-low friction and chemical resistance.
  • Composite steel and aluminum with fluoroplastic coatings provide corrosion resistance in harsh environments.
• Specialized Options: Cast iron variants with solid lubricants excel in high-temperature applications (>250°C).

2. Optimized Structural Designs

• Flange-Integrated Housing: Unique flanged designs simplify assembly and enhance axial load capacity.
• Versatile Configurations:
  
  • Straight bushings for compact spaces.
  • Collared designs for radial stability.
  • Block-shaped housings for vibration damping.
• Surface Treatments: Chrome-plated or nickel-plated coatings boost wear resistance and reduce galvanic corrosion.

3. Precision Engineering & Tolerances

• ISO-Compliant Tolerances: H7, G6, E7, m6, r6, and h7 ensure seamless integration with shafts and housings.
• Dimensional Flexibility:
  
  • Inner Diameter (d): 3 mm to 100 mm
  • Outer Diameter (D): 4.6 mm to 120 mm
  • Length (L): 3 mm to 188 mm
• Speed Capability: Operates reliably at 0.15–3.33 m/s, validated through rigorous life-cycle testing.

4. Maintenance-Free Operation

• Integrated Solid Lubricants: Graphite or PTFE disperses uniformly during operation, eliminating external lubrication systems.
• Cost & Space Efficiency: Reduces downtime and saves 15–30% installation space versus rolling bearings.
• Load Distribution: Larger contact areas support up to 2× higher static loads than equivalent ball bearings.

Applications & Industry Benefits

• Automotive: Steering linkages, throttle valves (benefit from POM’s low friction).
• Heavy Machinery: Conveyor rollers, hydraulic cylinders (leveraging cast iron’s thermal stability).
• Robotics: Joint actuators and linear guides (utilizing aluminum’s lightweight fluoroplastic coating).
• Aerospace: Landing gear components (relying on nickel-plated corrosion resistance).

Critical Design Insight: Service life depends on stroke length, surface roughness, and rotational speed. Our engineering team provides application-specific life calculations to optimize performance.
