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.

BX is a timing variant of the B profile. The profile, the dimensions 17 x 11 mm and the lengths Li 2120 mm, Ld 2163 mm and La 2189 mm describe the physical size of the belt.

Length measurement

The three lengths describe the belt from each measuring pu . The inner length is Li 2120 mm, the effective length is Ld 2163 mm, and the outer length is La 2189 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 BX 83.5 mean?

BX 83.5 is the classic supplier designation for the belt. The profile is BX, 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 BX profile mean?

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