Bronze worm wheels are essential components in the drive systems of BOBST machines. Paired with a hardened steel worm, they convert fast rotational movement into perfectly controlled motion—indispensable for precise positioning of the moving platen and other critical elements.
Bronze is selected for its excellent sliding properties, quiet operation, and progressive wear behavior, which protects the worm and ensures mechanical stability.
Each wheel is produced from a cast blank and then machined with a tool precisely matched to the profile of the worm, guaranteeing optimal meshing. Careful control of backlash, tooth contact, and load-bearing surface ensures uniform wear and a long service life.
Since replacing the wheel is complex and time-consuming, our components are designed with a high safety factor to deliver maximum durability and peace of mind.
Bronze (cast blank, precision-machined).
Drive system components for moving platen positioning and sector control.
Designed for use with hardened steel worm.
Controlled backlash, optimized tooth contact, maximized load-bearing surface.
Requires proper lubrication for optimal performance and longevity.
Bronze’s natural lubricity guarantees consistent operation with minimal friction, reducing wear on both the wheel and the hardened steel worm.
Cast bronze construction with precision machining delivers the structural integrity required for demanding production environments and heavy loads.
Progressive wear behavior and optimized tooth contact deliver quieter running compared to alternative materials.
Each wheel is machined with tools specifically profiled to match your worm, guaranteeing optimal meshing and uniform load distribution across the entire contact surface.
Bronze's progressive wear pattern protects the more expensive hardened steel worm, extending the life of your drive system.
BOBST original bronze worm wheels deliver the precision, durability, and reliability your production demands.
Since replacement is complex and time-consuming, investing in genuine parts with high safety factors protects your uptime and your bottom line.
Our specialists can help you identify the correct bronze worm wheel for your specific machine model and configuration.
