Metric Plain Guide Bushings Wring Fit Style

Metric plain guide bushings in Wring Fit Style are used in injection and stamping tooling to lock die sets into repeatable alignment as the press cycles. This variant’s rigid guiding helps reduce lateral drift, supporting stable parting-line geometry and consistent motion transfer.

• Automotive and industrial stamping die sets: Ideal for leader/guide areas where cyclic loads demand wear resistance. The bronze-plated, oil-free copper alloy guiding surface promotes smooth movement with less dependence on external lubrication.
• High-throughput production housings and brackets: Suitable where designers want quick mounting and dependable alignment under repeated start-stop cycles. The wring-fit guidance style supports predictable, steady contact.
• Tooling refresh and maintenance builds: Choose this bushing when rebuilding die sets and you need matched inner diameter and length ranges for a controlled guide interface. Optional grease-fitting regions (Europe or North America) make it compatible with shop standards.

Use ground or unground versions based on your required surface finish and fit strategy within the leader-bushing system.

These plain guide bushings use a bronze-plated, oil-free copper alloy construction to balance low friction guiding with resistance to wear under cyclic loading. The bronze plating improves surface durability at the sliding interface, while the oil-free copper alloy core supports stable mechanical behavior for guide applications.

• Wear resistance vs. toughness: The plated copper alloy system is optimized for guiding surfaces where abrasion and micro-wear dominate; the design trades maximum impact toughness for controlled wear performance during repeated cycling.
• Manufacturing approach: Bushings are produced in either ground or unground condition to match the assembly’s fit and surface finish requirements.
• Grease fitting integration: Configurations are available for Europe or North America grease-fitting standards, supporting lubrication practices where required.

Note: the provided data does not specify a particular steel grade or heat-treat state (e.g., quenched & tempered, nitrided), so those parameters should be confirmed with the supplier if heat-treatment details are required for qualification.

Select dimensions by matching the bushing inner diameter (d) and length (L) to your leader and guide bore requirements in the die set. For this series, d ranges from 18.011 mm to 80.016 mm and L ranges from 31 mm to 89 mm.

• Match the leader diameter: Choose d so the bushing ID is compatible with the leader’s working diameter. Since only nominal ranges are provided, confirm the intended fit (e.g., clearance/interference strategy) against your engineering drawing and assembly tolerances.
• Set guide engagement length: Choose L to achieve sufficient bearing/engagement length for stable alignment while maintaining space constraints around the die set.
• Ground vs. unground selection: Use ground bushings when tighter surface finish and consistent fit are critical; use unground when your downstream finishing or housing tolerances can accommodate the interface.
• Grease fitting standard: Select the Europe or North America grease-fitting option to match your lubrication hardware and maintenance tooling.

Dimensions are configurable within the stated ranges; fixed dimensions are determined by the specific catalog part number you select.
