STARK CX 85 belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for CX 85 and any equivalents.
The Stark CX 85 is a cogged classical V-belt in the CX profile. This page covers what the profile and the part number tell you before you request a quote.
The CX profile is a cogged classical V-belt section. The CX designation sets the cross-section, so the belt fits the sheave groove that takes a CX belt. The 85 in the part number is the length designation for this belt.
Cogged construction is the defining feature of the CX profile: the raw edge is notched along the underside. That notch pattern lets the belt bend more easily around smaller pulleys than a wrapped classical belt of the same section, and it helps the belt run cooler in drives where flexing is constant.
The same size is also listed under Optibelt CX 85 and Dayco CX 85, so if you are matching a belt already on the drive, those markings point to the same size. To request a quote, send the part number, the profile, and the length marking from the back of the old belt.
