Multi layer BEARPHITE

Using a new forming method, we have developed "Multi Layer BEARPHITE " having both high strength and wear resistance.

We developed an inexpensive bearing with mechanical strength, accuracy and oil retention.
Simultaneously molding two materials with newly developed integrated molding method
Having high strength and high hardness required for the construction machine bearings
High hardness iron-based material on the inner side as the sliding surface, and place the general structure of sintered material as the outer diameter side
In developed sizing possible material, machining of conventional process becomes unnecessary, and realize low price
Using the material for satisfying the sliding property only to the bearing part, realize low cost by making back metal of inexpensive material

Achieve high-strength and outstanding wear-resistance by the two-color molding method that molds the two different material at once

Radial crushing strength of 500MPa or more, oil content of 17 vol% or more
→ Optimized material and sintering conditions for the required strength and oil content without any special heat treatment
. Variation in inner and outer diameter dimensional precision of 50 μm or less
→ Sizing process used to maintain precision, eliminating the need for the cutting process
(values for (1) and (2) above obtained from test results of a bearing with dimensionsφ35×φ45×35)
