Oil-free Bushing – Self Lubricating Bushing- Design Your Parts!

Design according to customer requirements

As the self-lubricating bushing performance will be affected by the dual shaft material, hardness, surface roughness, whether there is a surface treatment, so the following recommended dual materials for reference. In addition, double or triple chromium plating should be applied in seawater or in medium corrosive conditions.

Introduction to Essential Considerations for Designing Effective Bushings

  1. Design and Selection Criteria for Self-Lubricating Bearings
    • Characteristics and Design Elements of Self-Lubricating Bushings:
      • Define the general design, including inner and outer diameter, length, dual shaft material, and lubrication method.
      • Assess environmental conditions and design specifications, considering both normal and special environments like high or low temperatures and exposure to liquids.
      • Examine usage conditions including permissible P, V, PV values, movement form, frequency, and oil supply necessity.
      • Investigate environmental factors such as temperature, potential for foreign body intrusion, corrosion resistance, and compatibility with chemicals.
    • Shape and Detailed Design:
      • Consider the material, strength, rigidity, and precision of the bushing seat.
      • Research and confirm dual shaft material properties like roughness, hardness, surface treatment, and precision.
      • Verify and confirm bearing accuracy, interference, clearance, and oil features.
    • Material Selection:
      • Evaluate if all design factors are within permissible values and select materials accordingly.
      • Confirm test data and characteristics, verifying calculated life and durability.
  2. P Value/V Value/PV Value of Self-Lubricating Bearing:
    • P Values: Maximum load divided by projected bearing area.
    • V Values: Relative speed between the dual and the bearing.
    • PV Values: The product of P and V values, a crucial factor in bushing selection.
    • These values are interrelated design parameters, not independent allowable values.
  3. Ambient Temperature and PV Value:
    • High Temperature Conditions: Set a lower PV value due to heat dissipation challenges and reduced friction characteristics at higher temperatures.
    • Low Temperature Conditions: Consider the impact strength and brittleness at low temperatures, and the reduction in clearance due to thermal shrinkage.
  4. Selection of Counterpart Materials:
    • For resin bearings, especially thermoplastic materials, consider the lower melting point compared to metal bearings and the significant impact of temperature changes on clearance and stress relaxation.

 Bearings | Self-Lubricating, Maintenance-Free

Our collection of  bushings is an ideal choice for projects where traditional lubrication is impractical or where standard lubricants might degrade under high temperatures. Eliminating the need for complex and costly oil feeding systems, our oilless bearings significantly reduce both maintenance and oil expenses by negating the requirement for such systems.

Viiplus bushings are distinguished by their excellent chemical and corrosion resistance. They incorporate lubricants made from wear-resistant materials like graphite and PTFE, which have a stable molecular structure.

These bushings are particularly well-suited for dry conditions where contamination is a concern, moist environments with high humidity, and situations where the bearing location is not easily accessible. Viiplus Oil-free Bushings come pre-lubricated, providing a lifetime of maintenance-free operation.
