The oilless guiding bush with collar, featuring self-lubricating properties, is a highly efficient and maintenance-friendly component designed for various industrial applications. The absence of the need for oil lubrication significantly reduces operational costs and maintenance requirements, making it an ideal choice for demanding environments. The collar reinforcement enhances the bush's structural integrity and durability, ensuring stable and reliable performance even under high loads. The self-lubricating material ensures smooth operation and reduced friction, contributing to overall efficiency and longevity.
Self-lubricating bushing - Long-term Wear Resistance
GUIDINGS AND SLIDINGS
Choose from our selection of self-lubricating bushings, including oil-embedded sleeve bearings, dry-running sleeve bearings, and more.
MATERIAL: Bronze Graphite
USE: Guide bush with collar (for centering between two plates), bronze with non-liquid lubricant; the material for self-lubricating reduces maintenance requirements.
Guide Bushes DIN 9834 / ISO 9448, Bronze, Maintenance-Free With
Collar Standard SO#50SP2
Solid Bronze Bearing is manufactured using high tensile manganese
bronze plugged with solid lubricants. Basic bronze alloy material
is CuZn25Al6Fe3Mn3 with graphite (SL2) plugged, we also provide a
widely optional choices from CuSn5Pb5Zn5, CuAl10Fe5Ni5, CuSn12, and
other standards materials.
Especially our company has developed the SL4 solid lubricants for water contacting applications like jet, propeller, ship, boatyard, offshore platform, hydraulic turbine, etc.
These products are mainly used in applications of high load &
moderate speed. It has the ability to withstand temperature up to
400oC. We also have the capability to develop these bushes and
plates as per any specifications of our clients.
