Polyurethane Metering Wheels

Flexible Zero-Crush Spacing Wheels

Since 1963, the world’s most trusted companies have relied on ML6® Precision Polyurethane from Meridian Laboratory as the solution provider for their manufacturing, processing, and packaging operations. Meridian Laboratory continues to innovate, recently adding No-Crush Wheels to its catalog of industry-leading precision polyurethane products.

Meridian Laboratory’s team of expert engineers developed an astutely functional teardrop design to allow the roller to flex over materials varying in thickness for firm but non-damaging contact. These Zero-Crush Wheels can be used in a wide variety of methods and industries in automation equipment, packaging machinery, bottling and labeling equipment, and more. Specially developed to remain flexible, while providing excellent durability and tolerances.

Meridian Laboratory No-Crush Wheels are cost effective with fast turnaround times. Like all other ML6 Precision Polyurethane products, No-Crush Wheels are available in Durometers ranging from 40A to 60D (Soft Eraser to Hard Hat Hardness). 40 Shore A (the softest option) and 55 Shore A are the most common durometers. Available in 7 standard colors with custom blending options and various core materials available.

Zero-Crush Rollers by Meridian Laboratory are available in a wide variety of sizes ranging from 2.50″ to 6″ outside diameter, up to 2″ in width, and bore sizes from 0.250″ to 1.00″. Meridian Laboratory can also manufacture custom bore sizes including Metric sizes quickly and cost effectively.

Meridian Laboratory’s precision process from tooling to molding ensures increased product longevity with the ability to meet exacting tolerances and specifications.

Key attributes:

  • Excellent for bottle/material spacing wheels and feed/hold-down rolls
  • Precision dimensional tolerances with low runout
  • Bond strength to core is stronger than polyurethane material itself
  • Wheels are designed to deform and protect materials being driven
  • Reduced wear and increased longevity of contact surfaces
