Sandvik 154 134 58 Bushing Bearing

The bushing bearing, part 154 134 58, is a plain bearing in sleeve form, used at a joint that swings through a limited angle rather than turning continuously. That distinction matters, because a continuously rotating shaft drags lubricant into the gap and floats on it, while an oscillating joint keeps stopping and reversing, so the surfaces spend much of their life in boundary contact and the bearing material itself has to tolerate that.

Wear in this kind of bearing tends to show up as slack in the joint rather than noise, so it is often found by checking free play with the load off instead of by listening. Greasing an oscillating joint on schedule is what keeps the sliding surfaces separated, and a bearing that has been run dry will wear out the housing bore along with itself. Matching the part number on replacement keeps the wall thickness and bore size that the pin or shaft expects.
