SF-2 Boundary Lubricating Bearing is with good load capacity and anti-wear performance. It's used under high load application & low speed rotation. It can work a period of time without greasing in the condition of boundary. If it's with oil or lubricates the machine at intervals, the life of the bushing will be longer. POM thickness is machinable. The bushings can be applied in Auto Chassis, forging Machine, Metallurgica Industry, Construction Machine, Mining Machining, Power Station, and Steel Rolling Equipment, etc. The groove is smooth so the lubrication is better. It's widely used in the lead-free application.
