Spherical Sliding: I save kamapim planti -daireksenel rotesen long rot bilong bungim ol 'ball studs' na 'ball sockets', na larim ±5 digri 'deflection angle'.
Seleksen bilong ol samting:
Hai-strongpela 'zinc alloy' (BL kain): Hai wear resistans, i gutpela long ol bikpela-lod aplikesen.
Hap-strongpela aluminium aloi (BL-A kain): I no hevi tumas, na i gutpela long ol ikwipmen we i gat gutpela wok.
Kabon stiel o bearing stiel: Planti taim ol i save yusim long ol 'rod end' na ol 'inner rings', ol i save putim hat-tritim bilong strongim 'wear resistance'.
Ol wok mak
Wear Resistance: I daunim lus bilong friksen long rot bilong ol gris poket o ol self-lubricating liners (olsem, sintered bronze, PTFE).
Load Capacity: Em inap long sanap strong long ol strong bilong presim na tanim; sampela model i save sapotim ol hevi lod (olsem, JAH series).
