SF-2S Lead-free Lubricated Bearing for Printing and Dyeing Machines

SF-2S oil-free lubricating bearing is an improved product of SF-2, with steel back matrix, sintered spherical tin bronze powder in the middle, and rolled surface with acetal resin and polymer material containing oleophilic fiber and special lubricant. The same product abroad is DS bearing, which is suitable for dry friction and less oil lubrication under normal temperature conditions. It has the advantages of low friction coefficient, good wear resistance and oil-free lubrication. At present, the product has been used in swinging motion, easy wear and corrosion, such as winders, bulldozers, printing and dyeing machines, coal mining machines, cranes, overhead cranes and other occasions.

Why Choose Oilless Bearings

Reduce Manufacturing costs

There is no need for oil supply device, oil injection hole or oil groove processing, which can greatly save manufacturing costs.

Reduce Operating Costs

It greatly reduces the usage of lubricating oil, reduces equipment maintenance, and avoids hidden dangers caused by insufficient oil supply, effectively reducing operating costs.

Shorten Design Time

The oil-free design simplifies the product structure and effectively saves design time. We are professional ODM Suppliers of SF-2S Lead-free Lubricated Bearing for Printing and Dyeing Machines

Conducive To Environmental Protection

No waste oil recycling is required, which is also beneficial to environmental protection.

Application Features

●Good load-bearing and wear-resistant performance.
●Suitable for rotating motion and swinging motion under high load and low speed, and occasions where frequent opening and closing under load make it difficult to form fluid dynamic lubrication.
●Under boundary lubrication conditions, it can be maintained without oiling for a long time, and oiling in the overlayer can make the bearing service life longer.
●The surface plastic layer can leave a certain margin during processing and molding, and can be processed by itself after assembly and pressing into the seat hole to achieve better assembly size.
●The product is mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, rolling equipment, etc.
●Because it does not contain lead, it can be widely used in lead-free fields.
