20 X 30mm Plain Bearing Bush Inlaid Sliding JDB Style Brass Sleeve Self Lubricating Bearings
Self-lubricant inlaid bearing is also known as oilless sliding bearing , it is a special design for equipments with heavy-duty , slow speed or circulating motion characteristics . the material consists of metal brass and solid lubricant , solid lubricant is absorbed by brass bearing body when bearings are put into it and this lubricant will reduce friction that from bearing .
