Bronze bushings are the better choice when a joint rotates continuously at moderate load and gets lubricated on a schedule. Hardened steel bushings are the better choice when the joint takes shock loads, carries high pressure over a small area, oscillates slowly through a few degrees, and lives in dirt. Most pin joints on construction,… Read more »

Lubrication for Radial Spherical Plain Bushings: Grease, Interval, and What Failure Looks Like

Spherical plain bushings are sliding bearings — the inner ring slides directly against the outer ring through a thin film of grease. When that film breaks down, wear accelerates fast. Bearings that should last years can fail in weeks. Step One: Know What Type You Have PTFE-lined (maintenance-free) bushings should not be greased at the… Read more »
