Gerolde’s FB090 Self-Lubricating Bronze Bushings – Maintenance-Free Excellence

Introduction: Revolutionizing Motion with Self-Lubricating Precision
In industries where downtime is costly and reliability is non-negotiable, VIIPLUS delivers cutting-edge solutions with ​Gerolde’s FB090 Self-Lubricating Bronze Bushings. Engineered from premium ​CuSn8 tin-bronze alloy, these maintenance-free glide bearings eliminate the need for external lubrication while offering unmatched wear resistance, high load capacity, and corrosion resistance. Ideal for automotive, construction, and heavy machinery applications, FB090 bushings ensure smooth operation in even the most demanding environments.

Why FB090 Bronze Bushings? Key Features & Benefits

1. ​CuSn8 Tin-Bronze Alloy:

   • ​Self-Lubricating Design: Embedded diamond-shaped lubrication pockets retain grease, forming a protective film that reduces friction at startup and during operation.
   • ​High Wear & Corrosion Resistance: Withstands harsh conditions, including moisture, chemicals, and heavy loads.
   • ​Thermal Conductivity: Efficient heat dissipation prevents overheating, extending component lifespan.

2. ​Maintenance-Free Operation:

   • ​Oilless Performance: Reduces downtime and maintenance costs by eliminating the need for regular lubrication.
   • ​Shockproof & Dimensional Stability: Maintains precision under radial, axial, and oscillating movements.

3. ​Versatile Configurations:

   • ​Thin-Walled, Lightweight Design: Space-saving and ideal for low-precision, cost-sensitive applications.
   • ​Customizable Inner Diameter (ID): Post-assembly machining ensures a perfect fit for diverse machinery.

4. ​ISO-Certified Quality:

   • ​ISO 9001 Compliance: Manufactured to global standards for consistent performance and reliability.

Applications: Where FB090 Bushings Excel

• ​Automotive Systems: Steering assemblies, transmissions, and suspension components.
• ​Heavy Machinery: Excavators, cranes, and hydraulic lifts.
• ​Industrial Equipment: Conveyors, agricultural machinery, and mining drills.
• ​Renewable Energy: Wind turbines and solar tracking systems.
• ​General Manufacturing: Precision machine tools and robotics.

Technical Specifications

• ​Material: High-density CuSn8 phosphorus tin bronze (low impurities, high purity).
• ​Lubrication: Pre-lubricated with diamond/oil grooves; compatible with grease or oil.
• ​Load Capacity: Optimized for medium to high loads and low-speed conditions.
• ​Temperature Range: Operates reliably from ​**-50°C to +200°C**.
• ​Tolerances: Shaft (e7/f7), Housing (H7).

Available Product Types

• ​Cylindrical & Flanged Bushings: For radial and axial loads.
• ​Thrust Washers & Sliding Plates: Ideal for oscillating motions.
• ​Custom Designs: Half-couplings, stamped, or deep-drawn components.

Bearing Play

To the H9 tolerance of the slide bearing we recommend shafts with tolerance e7 or f7. If h-shafts are used, the bearing inner diameter should be machined up to tolerance F7.

Structure

The bearings are wrapped in a homogeneous cold stamped bronze (CuSn8) with exceptional material properties. Standard sizes have diamond-shaped lubrication recesses in the bearing surface. These indentations serve as lubricant reservoirs to quickly create a lubrication film at the beginning of the movement and subsequently reduce running friction. The material is suitable for building applications and agricultural machines.
