Oil-impregnated bearings suitable for low speed and high load conditions.
"Polite DMP" is an oil-embedded bearing that enhances a copper alloy matrix by uniformly dispersing a solid lubricant, graphite, in large quantities, thereby reducing metal contact during sliding and improving durability under harsh operating conditions such as low speed, intermittent use, and high load. Due to the high content of solid lubricant, it excels in wear resistance under high load and low speed conditions compared to iron-based and conventional bronze materials, resulting in superior durability. 【Features】 ■ Being based on a copper alloy, it has less galling with shafts and offers high reliability. ■ Can also be used for oscillating motion specifications. ■ This bearing is used by press-fitting into the inner diameter of gears and pulleys and can be used under shaft fixation conditions (please consult a technician). ■ It is also possible to use it without oil in places where oil is undesirable (please consult a technician). ■ Compliant with ELV and RoHS. *For more details, please download the PDF or contact us.
