Thin-walled sintered oil-bearing bushings | Supports space-saving and cost reduction with a wall thickness of 1mm or less.

Addressing bearing arrangement in confined spaces and cost challenges of wrapped bushes with thin-walled sintered oil-bearing bearings.

As equipment becomes more compact, challenges arise such as "the gap between the shaft and housing is narrow, making it impossible to place bearings" and "we want to replace bushings to reduce costs." Balancing space-saving and sliding performance becomes a key point in bearing selection. DIA-MET's thin-walled sintered oil-impregnated bearings can be manufactured with a wall thickness of less than 1mm for both inner and outer diameters. They can be placed in tight spaces while maintaining sliding performance equivalent to that of standard sintered oil-impregnated bearings. ■ Space-saving design through thin-walling ▼ Can be manufactured with a wall thickness of less than 1mm ▼ Can be inserted into a 1mm gap between the shaft and housing ▼ Suitable for narrow spaces where ball bearings are difficult to place ■ Replacement of bushings ▼ Ensures good sliding performance through base material properties and oil impregnation in pores ▼ No sliding treatment required, which is necessary for unlubricated bushings ■ Cost reduction ▼ Net shape forming that does not require machining ▼ Maintains sliding performance equivalent to that of standard sintered oil-impregnated bearings This can be utilized in the bearing design of equipment aimed at miniaturization and reducing component costs.
