KSEW OILLESSE WEAR PLATE
The KSEW Slide Plate is a self-lubricating slide plate made from high-strength brass (CuZn25Al5/C86300) as the base material, with solid lubricant (graphite) embedded into the working surface of the base. The standard thickness is 20mm, and it is one of the standard models in the mold standard parts system of MISUMI and other manufacturers. This product is manufactured by embedding special solid lubricants at appropriate positions. The metal base material supports the load, while the embedded solid lubricant provides lubrication. Even under harsh conditions, it exhibits excellent self-lubricating durability. It is most suitable for locations that require frequent oiling, reciprocating motion or frequent start-stop operations, and locations where oil film formation is difficult. It can be used in a self-lubricating state without requiring oiling devices, which shortens assembly time, reduces oil contamination, and beautifies the environment. It also has excellent anti-seizure performance.

II. Material
|
The KSEW series uses high-strength brass as the base material, which has excellent mechanical and wear-resistant properties. Graphite is embedded into the copper alloy base in an embedded manner. During friction, the graphite transfers to the friction surface to form a solid lubricating film, achieving long-term self-lubrication.

V. Frequently Asked Questions (FAQ)
Q1: Besides the dimensions published in the catalog, can copper guide plates be customized according to requirements?
A: Yes. Products can be customized according to customer requirements, including dimensions, graphite arrangement, bolt hole positions, etc.
Q2: What is the difference between graphite depression and normal wear in copper guide plates?
A: Normal graphite wear is generally about 1mm below the surface, which is a normal phenomenon during use. If the graphite depression is clearly visible or can be felt by hand, it is a defect caused by graphite depression, mainly due to air escaping from the bottom of the hole during graphite embedding. If the graphite shows no wear after long-term use, it can be determined that the graphite used in such guide plates is carbon rod, which is not a good product.
Q3: What is the difference between the SEW series and the STW series?
A: Both KSEW and KSTW are copper alloy self-lubricating slide plate series. The main differences lie in dimensions and bolt hole configurations. SEW is the 20mm thickness standard type, while STW is usually the 10mm thickness type. Both have basically the same material and performance parameters.
