ROLLER SIDE (Nissan NI23018-20306)

A worn side roller can cause uneven wear on the mast channel surfaces. This aftermarket replacement part references Nissan as the OE maker and carries the cross-reference number NI23018-20306. The side roller functions as a guide component that maintains proper alignment between the mast sections. Its plain mechanical function is to rotate on a bearing or bushing while contacting the mast channel. A generic failure consequence is that a seized or worn roller can produce metal-to-metal contact, leading to galling or scoring of the mast surfaces. During a typical service interval, a technician may notice increased play or binding in the mast movement. Verify the serial number or application, then call (562) 693-7748.
