Surface treatment Synchronising pulleys Surface refinement for synchronising pulleys made from aluminium Materials for synchronising pulleys Surface treatment Use Brief description Anodising Decorative corrosion protection for the surface Layer thickness to max. 20µm The layer hardness is in the range 250-350 HV, the oxide layer resulting from anodising ensures very good resistance to wear and prevents corrosion symptoms. BRECO provides various materials for diverse areas of application for synchronising pulleys. We only use pressed and drawn semi-finished products so that the technical...

Special geometries Machining/Special geometry according to customer‘s need Machining/Special geometries according to customer requirements The ever-increasing requirements for low-friction, low-noise and precise drive elements continually present us with new challenges. Thanks to modern production technology, BRECO can offer its customers extensive machining options as well as special geometries for individual adaptation of the synchronising pulleys to the relevant application. The combination with the optimised BRECO® or BRECOFLEX® timing belts results in drive elements that ensure a very...

Tooth gap design Tooth gap design Tooth gap forms Timing belts are positive fitting drive elements. They work slip-free with the associated synchronising pulleys. BRECO- and BRECOFLEX- timing belt drives can also be optimised to motion transmission that is low in flank play. For especially high requirements with respect to the accuracy of the motion transmission, the SE or zero gap can be used for some profiles and divisions in compliance with certain prerequisites. Our sales partners will be pleased to help with the technical design of your drive. Ordering information: Normal gap SE gap...
