Solid Lubricant Plugged Bearings: Selection Guide
Bronze alloys combined with solid lubricant inserts (e.g., Graphite, PTFE) are highly favorable for heavy-load, low-speed applications where conventional grease maintenance is impractical or impossible. Use the guide below to align specific industrial sectors with appropriate alloy families.
Power Generation
(Hydro, Wind, Solar)
Wicket gate bearings, guide vanes, wind pitch control linkages, solar tracking pivots.
Requires maintenance-free operation over long lifespans, handling high static loads and preventing fretting wear. High-strength brass or aluminum bronzes with graphite plugs are commonly specified.
Heavy Industry & Mining
(Steelworks, Public Works)
Continuous caster trunnions, furnace tilt pivots, TBM cutter head supports, tunnelling machinery.
Operates in extreme dust, abrasive conditions, and elevated temperatures. High-strength aluminum bronze with solid graphite provides excellent thermal stability and dry boundary lubrication.
Marine & Hydromechanical
(On/Offshore, Naval)
Offshore mooring fairleads, dam gate pivots, subsea ROV linkages, hatch covers.
Constant exposure to saltwater and wave impacts. Requires superior galvanic corrosion resistance. Nickel-Aluminum Bronze is highly favorable, often paired with PTFE-enhanced plugs.
Machinery & Fluid Control
(Pumps, Valves, Lifting)
Butterfly valve stems, gear pump journals, packaging machine toggle joints, crane sheaves, winches.
Needs reliable start-stop friction reduction and prevention of stick-slip under heavy radial loads. Tin bronzes are suitable for moderate loads, while high-strength brass is preferred for hoists.
