● Irola eyi-cylindrical yomugqa owodwa eveza amandla e-radial kuphela, ukuqina okuhle, ukumelana nomthelela.
● Ifanele ama-shaft amafushane anezisekelo eziqinile, ama-shaft ane-axial displacement okubangelwa ukuphakama kwe-thermal, kanye nezinsiza zomshini ezinama-bearings ahlukanayo ukuze afakwe futhi ahlakaze.
● Isetshenziselwa kakhulu injini enkulu, ukuphotha kwethuluzi lomshini, i-shaft esekelayo yenjini ngaphambili nangemuva, i-axle yemoto yomgibeli esekela i-shaft, injini ye-diesel crankshaft, i-gearbox kagandaganda wemoto, njll.
