Tension Link Retainers Single Flange

Tension link retainers with a single-flange design are used in injection mold opening and closing systems to hold tension link hardware in a fixed, repeatable position. They are commonly specified in automotive connector and housing molds, where controlled motion reduces knock and helps maintain dimensional stability across high-cycle production.

For appliance and consumer product molds, engineers often choose the variant with an optional urethane wrap when impact damping and improved grip are needed. The urethane inclusion (when selected) can help reduce transfer of opening/closing shock to surrounding components.

In service and maintenance-oriented mold builds, supplying the retainer either as retainer only or as retainer + bolt supports faster refurbishment and consistent assembly. Select the retainer by matching the special bolt diameter range (D = 10, 13, 16, or 20 mm) to ensure proper alignment and reliable retention within the tension link assembly.

The provided specifications define geometry and compatibility (flange, bolt diameter D, and lengths L) but do not state a specific steel grade or heat-treatment condition. As a result, the exact material properties, hardness (HRC), and any quench-and-temper/nitriding process cannot be confirmed from the input data.

What can be stated for material-related configuration is the urethane option:

• Urethane in retainer = No for rigid retention where cushioning is not required.
• Urethane in retainer = Yes to add damping and grip, trading some rigidity for improved shock absorption.

If you need to verify wear resistance, toughness, or hardness for wear-prone molds, please request the material cert or datasheet for the selected sales form (retainer only vs. retainer + bolt, with or without urethane).

Use the tension link special bolt diameter parameter D to match the retainer to your mold’s tension link bolt size. Available diameters are D = 10, 13, 16, or 20 mm; selecting the correct D is essential for proper alignment and dependable assembly fit.

Then confirm the retainer length L, with available options of L = 16 or 24 mm. This length should match the spatial envelope on the single-flange assembly so the retainer seats correctly without interfering with adjacent link components.

• Configurable options: urethane inclusion (No/Yes) and sales form (retainer + bolt, retainer only, retainer with urethane only, retainer with urethane + bolt).
• Fixed sizing: D and L are fixed per variant; there are no adjustable dimensions in the provided spec.

For fit assurance, treat D as a compatibility selector and verify that your bolt and mating tension link hardware meet the same diameter family for full retention. Tolerance values are not provided, so confirm stack-up clearances in your CAD before finalizing the build.
