Breco Timing Belt Pulleys

BRECO pulleys are widely used in:

• Industrial automation and robotics
• Packaging machines and conveyor systems
• Handling equipment and logistics automation
• CNC machinery and precision positioning axes
• Printing, textile, and processing machinery
• Food and beverage production lines (stainless steel variants)
• OEM machine building requiring reliable synchronous drives

(Values will vary depending on pulley type)

• Material: Aluminium, steel, or stainless steel
• Available Profiles: AT3, AT5, AT10, AT20, ATK self-tracking, ATN, T5, T10, T20, HTD 5M, 8M, 14M, BAT, SFAT
• Tooth Gap Options: Normal gap, SE reduced gap, zero gap (depending on profile and tooth count)
• Surface Treatments: Anodising, hard anodising, hard coating, galvanising, browning, chemical nickel plating, Easy Glide PTFE coating, plasma nitriding
• Manufacturing Tolerances: Bores H7; other dimensions per DIN 7168 medium class
• Custom Machined according to your drawing
• Compatible Belts: BRECO and BRECOFLEX polyurethane timing belts

BRECO pulleys are typically used together with:

• BRECO and BRECOFLEX polyurethane timing belts
• Synchronising shafts (AT, T, HTD profiles)
• Tensioners and tension rollers
• Clamping plates and tension plates (BRECO-fix)
• Belt tension measuring device BRECO TSM alpha 1

Bondy A/S supplies the full range of BRECO pulleys with technical guidance, design support, and product selection assistance. Our engineers help calculate drive dimensions, choose correct profiles, and specify tooth gap tolerances.

With in-house machining facilities, Bondy offers custom bores, keyways, flanges, grooves, and special pulley geometries, ensuring seamless integration into OEM machinery. Large local stock and efficient logistics enable fast delivery across Europe, supporting both prototyping and high-volume production.

What is the difference between AT, T, HTD, and ATN pulley profiles?
AT profiles provide high power transmission and precise positioning; T profiles are suited for general purpose drives; HTD is optimized for rounded-tooth high-torque applications; ATN features modular tooth inserts for transport and positioning tasks.

When should I choose SE gap or zero gap pulleys?
SE and zero-gap geometries minimize flank play and are recommended for high-precision positioning systems or servo drives where backlash must be reduced.

What materials are recommended for corrosive or hygienic environments?
Stainless steel grades such as X5CrNi1810 (1.4301) or X6CrNiMoTi17-12-2 (1.4571) provide excellent corrosion resistance and are suitable for food and beverage applications.

Are self-tracking pulleys necessary for all applications?
Self-tracking ATK and ATN pulleys are used where belt guidance without flanges is required. Standard pulleys with flanges or precise alignment are sufficient in most applications.

Can Bondy A/S supply customised pulleys?
Yes. Bondy offers custom hub designs, special bores, extra machining, lightweighting features, and surface treatments based on customer specifications.
