Self-lubricated sintered bronze cylindrical Cap with flange 14-18-6/22-2mm, inner diameter 14mm, outer diameter 18mm, length 6mm, flange diameter 22mm, flange thickness 2mm. Model suitable for work under axial load, with or without radial load (the flange allows the axial load to be absorbed). The oil contained in the bearing provides constant lubrication between the bushing and the shaft, so the system does not need additional lubricant, therefore being maintenance-free for long periods of time. Self-lubrication results in a very low coefficient of friction, allowing high speeds to be reached.

Used in multiple applications both industrial and in homes, electrical or mechanical equipment for automobiles, linear and rotary actuators, agricultural sector...

Sintered self-lubricated cylindrical bearings are metal components with high porosity (20-25% by volume) impregnated with lubricating oil. The oil contained within the porosity of the bearing continuously provides lubrication between the bearing and the shaft, so the system does not need additional lubricant or maintenance after assembly. Self-lubrication allows these bearings to work with a very low coefficient of friction, allowing high speeds to be reached. These bushings are ideal for environments with a lot of dust, where the use of oil is not possible; They are also suitable for applications in contact with water or bronze-compatible liquids.


The system consists of a sintered bearing with the porosity filled with lubricating oil, and a shaft located inside the bearing, which rests on the inner diameter of the bearing. The rotation of the shaft causes a depression that sucks the oil from the pores of the bearing. This oil forms a lubricating film between the bearing and the shaft. This film is continually renewed with the oil that comes out of the pores. The oil is reabsorbed in the pores of the bearing by capillarity, but the lubricating oil film remains in the working area without being reabsorbed. When a new work cycle begins, the bearing is already working at full speed.


The main advantages of this type of self-lubricated sintered bearings is that they do not require grease fittings or maintenance after assembly, eliminating any risk of seizure; They have a very low noise level in optimal working conditions; They have a long useful working life without suffering progressive wear, under dynamic load up to 10 MPa (100 Kg/cm2) or linear speed up to 5 m/s (30,000 rpm maximum).

These bushings are ideal for environments with a lot of dust, where the use of oil is not possible; They are also suitable for applications in contact with water or liquids compatible with bronze. This type of bearings are used in multiple and varied applications such as electrical or mechanical equipment for automobiles, electric motors and reduction boxes, linear and rotary actuators, household appliances, home applications, industrial and agricultural sectors and other markets such as mobility, medicine, hospitality. , agricultural, toys, etc.
