Self-lubricating plastic bushings perform exceptionally well in applications where excessive friction is a concern. They ensure clean, maintenance-free operation in the harshest environments.

Self-lubricating bushings offer very good wear & low friction performance over a wide range of loads, speeds, and temperatures in dry running conditions High-Performance Bushings Bushing Material Bushing Description Bushing Data Bronze Self-lubricating Bearing Material PTFE/Pb mixture 0.01~0.03mm Copper powder layer 0.2~0.35mm

Plastic bushings run longer in harsh environments, are self-lubricating, resistant to corrosion, reduce and stabilize the coefficient of friction, and last significantly longer than metal bushings. When you consider the advantages of plastic bushings, you realize that they save you money both when you purchase them and as time goes on.

Self-lubricating Guide Bushings Features With high loads and low speed When oil or grease lubrication is not desired or not available. Mode of operation: Deposits (boreholes or groves) of solid lubricant are distributed with a proportion from 25% to 35% in the sliding surface of the base material.

Self-lubricating material

There are several different types of self-lubricating materials used in bearings, including:

Solid film lubricants are frequently made of metals like molybdenum disulfide or graphite. They work by depositing a thin film on the bearing’s surface, which reduces friction and wears.

Fluoropolymers are synthetic materials containing fluorine atoms. They are frequently used in applications involving high temperatures and/or corrosive environments.

Composite materials: These bearings are made up of a variety of materials, including metal and plastic. They typically have a high

  • self-lubricating polymers (POM)

Self-lubrication is provided for start-up, shut-down, and emergency situations. Lubrication also increases the load-carrying capacity of a bearing. Self-lubricating bearings do not stick when turned on. A bronze bushing and Babbit, for example, have a start-up coefficient of friction of around 0.3, whereas a PTFE-based bearing has only 0.05.

  1. Self-lubricating plastic bearings can be utilized with little to no maintenance and are ideal for situations where refueling is impossible or highly difficult.
    2. Plastic bearings that lubricate themselves and have good wear resistance; in general, lubricated materials with low coefficients of friction and extended service lives are used in plastic bearings.
    3. Self-lubricating plastic bearings are resistant to rust and corrosion, but rust-prone metal bearings cannot be utilized in chemical fluids.
    4. Self-lubricating plastic bearings are less heavy than metal, which makes them more suited to the current trend toward lightweight construction.
    5. Self-lubricating plastic bearings have lower manufacturing costs than metal bearings; injection molding technology is better suited for mass production, and self-lubricating plastic bearings are now in use.
