V-belt CX 39 / 990 Li 22x14 MM - PIX X'tra®

V-belt CX 39 / 990 Li 22x14 MM - PIX X'tra®

V-belt CX 39 / 990 Li 22x14 MM - PIX X'tra® is a Cogged V-belts in CX profile. The Raw-Edge construction provides direct side contact in the V-groove, while the timing underside makes the belt more flexible around the pulleys.

Construction and function

PIX X'tra® is built like a Raw-Edge V-belt. The sides lie directly against the pulley grooves and the serrated underside helps the belt bend around the pulleys. The serrations are on the underside and are used for flexibility while still transmitting power through the sides of the belt.

CX is a timing variant of the C profile. The profile, the dimensions 22 x 14 mm and the lengths Li 990 mm, Ld 1046 mm and La 1078 mm describe the physical size of the belt.

Li, Ld and La

The belt is given with Li, Ld and La because V-belts are measured differently depending on the measuring pu . Here Li is 990 mm, Ld 1046 mm and La 1078 mm.

Material

The V-belt is made of rubber with polyester reinforcement. The reinforcement helps the belt to maintain a stable length during operation, while the rubber provides the necessary flexibility around the pulleys.

The timing underside is particularly relevant for smaller pulley diameters, because the belt can bend more easily without becoming unnecessarily stiff.

FAQ

What does CX 39 mean?

CX 39 is the classic supplier designation for the belt. The profile is CX, and the belt must be used with pulleys with the same profile.

What do Li, Ld and La mean?

Li is the internal length, Ld is the effective length, and La is the external length. All three measurements are length measurements in millimeters.

What does CX profile mean?

CX is a timing classic V-belt profile. The belt has raw-edge sides and a timing underside.
