AE Type Heavy-Load Urethane Pillars Through Hole

These heavy-load urethane pillars are used as compliant spacers and load-support posts inside injection mold tooling and industrial fixtures where repeatable positioning under force is critical.

• Automotive and appliance assembly molds: The through-hole pillar form helps maintain alignment between plates or subassemblies while allowing controlled deflection, which improves stability during clamp/actuation cycles.
• Post-mold inspection jigs and fixturing: Their pillar shape and Shore A90 urethane formulation support consistent workpiece elevation and reduce vibration during handling.
• Machine guarding and sensor/limit fixtures: The controlled compliance (up to 25% maximum elongation) helps absorb shock loads without permanent misalignment.

The through-hole design is particularly suited for builds that require locating hardware or fasteners for precise assembly, while the heavy-load urethane provides practical economy performance for shop-floor replacement.

This product uses a Shore A90 urethane formulation, selected for high durability among elastomeric support components. Urethane provides elastic recovery and wear resistance suited to repeated compression and minor misalignment compensation.

• Hardness / performance trade-off: Shore A90 balances stiffness and toughness—stiffer than softer durometers for heavy-load support, while still offering controlled elongation.
• Heat treatment state: As a molded urethane component, it is not specified as quenched/tempered steel; performance is achieved through polymer curing/molding rather than metallic heat treatment.
• Wear & toughness: Higher durometer generally improves load capacity and indentation resistance, while extreme hardness can reduce ultimate elongation—this variant is rated for up to 25% maximum elongation.

Compared to lower-durometer urethane pillars, this grade typically reduces rebound and deformation under load, improving dimensional stability in tooling and fixtures.

To select the correct pillar, match three variables to your mold cavity/core or fixture space: D (outer diameter), L (length), and the required maximum load.

• Outer diameter (D): Choose within 15 to 60 mm to fit the available mounting envelope and provide the intended contact/stacking area.
• Length (L): Select within 25 to 80 mm to achieve the required stand-off height between plates, ejector support surfaces, or fixture contacts.
• Maximum load (N): Verify the expected force falls below the selected unit’s 932 to 16769 N range.

Consider tolerance and fit around the through hole: ensure clearance for the locating hardware so the pillar can contribute controlled compliance without binding. For multi-pillar assemblies, align multiple units to keep consistent deflection under load, maintaining uniform spacing during operation.
