SKF manufactures bushings in various designs and from different materials. Therefore, SKF offers a wide assortment of bushings available from stock.
Bushings are suitable for rotating, oscillating and linear movements, whereas straight (cylindrical) bushings can accommodate radial loads only and flanged bushings can accommodate radial and axial loads in one direction.
Each combination of bushing design and material has characteristic properties and makes a bushing particularly suitable for certain applications.
SKF Solid bronze bushings are available in metric sizes as straight (fig. 1) or flanged (fig. 2) bushings. This robust bushing material is suitable for a wide range of applications. These bushings are applicable for oscillating movements in both radial and axial directions or for applications where rotating speeds are low.
Solid bronze bushings can be lubricated with oil or grease, whereas the lubricant not only improves the sliding properties, but also reduces wear and prevents corrosion. Those bushings with a bore diameter d > 14 mm have an an axial lubrication groove in its sliding surface and are indicated by the designation suffix G1.
All surfaces of a solid bronze bushing are machined.
SKF sintered bronze bushings are available in metric sizes as straight (fig. 3) or flanged (fig. 4) bushings. These self-lubricating and maintenance-free bushings consist of a porous bronze matrix impregnated with a lubricant. The oil impregnation enables very high sliding velocity and makes these bushings suitable for rotating applications.
