💡 Why choose oilless journal units for high vibration workshop machines? Plain bushes solve the wear issue by locking factory oils inside the porous wall. - Sintered bronze cores absorb shock and prevent metal from scoring moving parts - Carbon steel foundation carries heavy thrust loads without flattening out - Dry running tolerance keeps your gear handy and rolling through dusty jobs - Swap these in fast since they match standard round housing bores
