Pile driver bushings

Pile driver is used to driving piles into the soil to provide foundation support for buildings or other structures. The term is also used to refer to a construction worker working with a piling rig. One type of pile driver USES heavy weights placed between guide rails to enable vertical sliding. It sits on top of a pile. Weight gain, which may involve hydraulic, steam, diesel, or manual labor use. When the weight reaches its highest point, it is released and hits the pile, driving it into the ground.

POM comsposite steel backed bushing

• maintenance-free operation
• very good frictional properties
• high load carrying capacity
• high sliding velocity
• small operating clearance

Material of composite POM bushings

POM composite plain bearings are suitable for applications that require minimal maintenance in difficult operating conditions. As a result of the lubricant holding pockets on the sliding surface, POM composite bearings are especially suitable for applications in contaminated environments, where the lubricant cannot be supplied continuously or frequently.

POM composite bushings Structrue

1. POM thickness 0.30 ~ 0.50 mm. Providing high wear resistance and low friction even with a minimal volume of lubricant, this bearing surface has a pattern of circular indentations which should be filled with grease during bearing assembly.

2. Thickness of sintered bronze powder 0.20-0.35 mm. A special composition of powdered copper is thermally fused to the steel support. This contact layer acts as an anchor for the PTFE layer and moves heat build-up away from the bearing surfaces.

3. Low carbon steel. Establishing the base of the bushings, the steel back provides exceptional characteristics of stability, load and heat dissipation.

Technical Data

POM composite bushings Application

POM composite bushings are suitable for applications where a sliding material with self-lubricating properties is essential.

• agricultural equipment
• construction machinery
• material handling equipment
• home appliances and consumer goods

Lubrication of POM composite bushings

POM composite plain bearings are designed for marginal lubrication. The sliding surface of these plain bearings contains grease reservoirs that must be filled before assembly. There is no need to re-lubricate these plain bearings, but the presence of lubricant can significantly extend the service life of the plain bearings. Grease may be applied periodically to protect the counterface from corrosion.
