V-Belts SPZ
SPZ V-belts are among the narrow V-belts used in industrial drives with higher power transmission density. The SPZ profile is part of the narrow V-belt system according to DIN 7753 / ISO 4184 and is characterized by a compact cross-section of approximately 9.7 × 8 mm. Thanks to this profile, it is possible to transmit higher power with a smaller belt width than with conventional profiles.
SPZ V-belts are used in drives for fans, compressors, pumps, machine tools, and agricultural equipment. The profile is designed for narrow-profile pulleys, which enable more efficient power transmission and a more compact drive design.
The range mainly includes SPZ coated V-belts with a textile surface that protects the belt against wear and increases its service life. An alternative is XPZ V-belts, which have a cogged design with notches on the inside for greater flexibility and better heat dissipation during operation.

SPZ V-belt design
The V-belt is made of a rubber compound reinforced with polyester or aramid tensile fibers that transfer the tensile load. The outer textile cover protects the belt against abrasion and ensures stable friction in the pulley groove. The V-profile ensures a self-locking effect in the pulley, allowing the belt to transmit power without slipping.
