A heavy-duty flexible bearing or bushing combines a high-load capacity with an ability to accommodate torsional and angular movements in all planes without lubrication or metal-to-metal wear. The Spherilastik Bearings come in center bore or as a solid member depending on how it’s attached.
Typical uses include equipment in wind turbines, traction and braking reaction arms for rail, road, and off-road vehicles, hydraulic damper fixings. The bearing works well on wind turbines where high frequency vibrations must be isolated while accommodating high thrust forces. The rubber section is bonded to the spherical inner member and to the outer. When pressed into the bearing housing, the three segments preload the rubber in compression. Preloading increases its resistance to fatigue, thereby extending its working life.
