DANLY IEM Short Shoulder Plain Guide Bushings - Self-Lubricating, Demountable Style

This demountable short-shoulder guide bushing is used in injection mold and die sets where consistent plain guide rigidity directly affects alignment, especially during long production runs. Its self-lubricating design helps maintain stable sliding under repetitive open/close cycles.

• Automotive and appliance die sets: In leader/ejector guided systems, the bushing’s copper alloy and plain guide geometry support smooth motion while reducing stick-slip that can disturb cavity alignment.
• Electrical connector and terminal molds: Short-shoulder guidance supports precise movement of mold halves, and the demountable style enables faster replacement during maintenance windows.
• General-purpose hot/cold runner die tools: The ability to install with clips/screws or by adhesive supports fit-up in constrained die-set layouts.

Choose the variant with the required post diameter and length to match the guide interface, leveraging the self-lubricating copper alloy for reliable, low-maintenance guidance.

The bushing is specified as a durable copper alloy for reliable die-set guidance in self-lubricating plain guide applications. Copper alloys provide good sliding behavior and wear resistance, which helps preserve alignment accuracy in leader/ejector guided systems subjected to repeated motion.

Because the provided data does not list an exact steel/bronze grade, heat-treatment condition, or target hardness (HRC), those parameters should be confirmed with the manufacturer or supplied material certificate before qualifying for critical wear or impact requirements.

• Wear resistance vs. toughness: Copper alloy plain bearings typically trade some impact toughness compared with tool steels, but deliver stable friction characteristics for guidance.
• Heat treatment: No nitriding/quench & temper details are provided for this copper alloy component; treat the material behavior as “as-manufactured” unless your qualification documentation specifies otherwise.

If you are comparing materials, bronze/copper alloy guide bushings are generally selected over hardened steel guides to prioritize low-friction stability and maintainability.

To select the correct bushing, match the guide interface dimensions to your die-set’s leader/bushing post geometry. This series is defined by post diameter A in the range of 1 ~ 4 in and length L in the range of 1.875 ~ 8 in.

• Post diameter (A): Choose the bushing size where A fits the leader post diameter used in your mold base or guide system.
• Length (L): Select the shortest length that still provides full guidance contact within your closed/open stroke envelope, to avoid over-constraining movement.

Because the input data does not specify tolerances, engineers should apply the mold’s standard fit strategy for guide bushings (clearance/press-fit or adhesive fit as designed) and verify against your existing leader post tolerance stack. Installation is demountable and supports fastening via clips/screws or adhesive (e.g., Loctite), so confirm fit method compatibility with your cavity/core assembly clearances.
