V-belt AX 28 / 710 Li 13x8 MM - PIX X'tra® is a PIX X'tra® V-belt with Raw-Edge sides and timing underside. The AX profile and the dimension 13 x 8 mm must fit pulleys with the same profile.
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.
AX is a timing variant of the A profile. The profile, the dimensions 13 x 8 mm and the lengths Li 710 mm, Ld 746 mm and La 760 mm describe the physical size of the belt.
The three lengths describe the belt from each measuring pu . The inner length is Li 710 mm, the effective length is Ld 746 mm, and the outer length is La 760 mm.
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.
AX 28 is the classic supplier designation for the belt. The profile is AX, and the belt must be used with pulleys with the same profile.
Li is the internal length, Ld is the effective length, and La is the external length. All three measurements are length measurements in millimeters.
AX is a timing classic V-belt profile. The belt has raw-edge sides and a timing underside.
