The advanced technological process allows the bushing to adapt to the deformations arising at high revolutions and helps in the production of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them an ideal solution for tight Most of the bushings are also available in several other dimensions: STDX -0.025 mm (looser than nominal) STD +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0, 50 mm (second shaft grinding)
