SF-2Y boundary lubricated lead-free bearings

SF-2Y boundary lubricated lead-free bearings

SF-2Y boundary lubrication lead-free bearings are an improvement on the basis of SF-2X. Its performance is the same as that of SF-2X, but the surface is lead-free, and the field of use can be extended to areas with environmental protection requirements.


Material organizational structure


1. Polyoxymethylene and fiber mixture 0.3-0. 5mm

2. Spherical bronze powder 0.2-0. 3mm

3. Steel back 0. 4-2. 2mm

4. Electroplating layer: tin plating layer thickness 0.005mm, or copper plating layer thickness 0. 008mm

Application features


1. Good loading, good friction resistance.

2. It is suitable for rotational movement, rocking movement and frequent opening and closing under load and occasions where hydrodynamic lubrication is not suitable for forming at medium load and low speed.

3. Under the condition of boundary lubrication, it can be maintained without oil for a long time, and the oil is added in the layer to make the bearing service life longer.

4. The surface plastic layer can leave a certain margin when processing and molding, and after the assembly is pressed into the seat space, it can be processed by itself to achieve a better assembly size.

5. Products are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment and imported textile equipment, plunger pump swing parts, automobile joystick parts, etc.

6. Because it does not contain lead, it can be widely used in lead-free fields.
