Tension Links Long Stroke Oval Hole

Q: How do I select the oval-hole length when designing a long-travel tensioning mechanism?

Select the oval-hole length using the series’ configurable 5 mm increments . Choose the increment that positions the linkage to achieve the target tension profile over the extended motion range, while ensuring sufficient travel before the limit of the oval slot.

Q: What are the available thickness and width options for this tension link, and how do they affect mounting?

This SKU provides thickness options of 9 mm or 16 mm and widths A of 19, 25, 32, 38 mm . Use thickness for structural stiffness within the available space, and use width A to match the mating bracket or linkage envelope to prevent misalignment during actuation.

Q: How do I match slotted hole pitch (S) and the SC dimension alteration to my mating components?

Choose S within 50 ~ 100 mm to align the slotted-hole spacing with the mounting features on the mating parts. Then confirm SC is within 51 ~ 101 mm so the required offset between mounting and actuation geometry is maintained.

Tension links long stroke oval hole are designed for long-travel tensioning applications, using a configurable oval-hole length system in 5 mm increments. The long-stroke geometry helps maintain consistent tension across extended motion ranges.

Product Guide

🏭Application Scenarios+

This tension link variant is used in injection mold opening and mold-opening controller systems where a long-travel mechanism must maintain stable tension over extended motion. Its configurable oval-hole length in 5 mm increments lets tooling engineers tailor linkage travel so the controller engages smoothly without over-stressing the tensioning hardware.

Common scenarios include:

Long-travel automotive connector molds: helps fine-tune the actuation timing and force transmission as mold sections move through a larger stroke range.
Packaging and appliance housing molds: supports repeatable tension control during opening/closing cycles, improving consistency across long-running production.
Industrial automation gripper and transfer fixtures (shared mold-opening control principles): provides adjustable link geometry for smooth tension behavior under varying setup requirements.

The oval-hole design and thickness options (9 mm or 16 mm) make it suitable when designers need flexible mounting and adjustment while preserving controlled actuation throughout the travel profile.

🔧Material & Process Details+

Material and heat-treatment details are not provided in the available product data. Therefore, hardness (HRC), specific wear-resistance performance, and the exact steel grade/standard (e.g., SKD61 / H13 or SKH51 / M2) cannot be stated reliably for this SKU.

For engineering compatibility, request the latest material certificate or drawing revision from the supplier to confirm:

Steel grade / equivalent and any surface treatments (e.g., nitriding, carburizing) if applicable
Heat treatment state (pre-hardened vs. quenched & tempered) used for dimensional stability
Hardness (HRC) and the expected toughness/wear trade-off based on the intended load and cycle life

If multiple material options exist for the series, compare them by hardness and toughness targets required by the tensioning loads, rather than selecting only by geometry.

📐Sizing & Selection Guide+

Start sizing by matching the link’s built-in geometry and available stroke adjustment to the mold’s mechanism requirements. This product supports oval-hole length configuration in 5 mm increments, so select the oval-hole length that aligns the controller linkage position for the desired tension profile during long-travel opening.

Thickness (mm): choose 9 or 16 based on space constraints and structural stiffness needs.
Width A (mm): select from 19, 25, 32, 38 to suit the linkage bracket and allowable envelope.
Slotted hole pitch S (mm): use a value in the range 50 ~ 100 to match mounting hole spacing on the mating components.
SC (mm): ensure the specified 51 ~ 101 dimension alteration matches the required offset between mounting and actuation geometry.

When integrating, verify the mating parts’ hole spacing and consider assembly clearance and alignment tolerance so the link can slide/actuate across the configured oval-hole travel without binding.

Frequently Asked Questions

How do I select the oval-hole length when designing a long-travel tensioning mechanism?+

Select the oval-hole length using the series’ configurable 5 mm increments. Choose the increment that positions the linkage to achieve the target tension profile over the extended motion range, while ensuring sufficient travel before the limit of the oval slot.

What are the available thickness and width options for this tension link, and how do they affect mounting?+

This SKU provides thickness options of 9 mm or 16 mm and widths A of 19, 25, 32, 38 mm. Use thickness for structural stiffness within the available space, and use width A to match the mating bracket or linkage envelope to prevent misalignment during actuation.

How do I match slotted hole pitch (S) and the SC dimension alteration to my mating components?+

Choose S within 50 ~ 100 mm to align the slotted-hole spacing with the mounting features on the mating parts. Then confirm SC is within 51 ~ 101 mm so the required offset between mounting and actuation geometry is maintained.

Is there a recommended material grade or hardness level for this tension link in high-cycle injection mold use?+

The provided product data does not specify the steel grade, heat-treatment condition, or hardness (HRC). For high-cycle use, request the material certificate or drawing data to confirm the heat treatment state and hardness, and then evaluate suitability against your tension load and cycle-life targets.

What tolerance/fit should I consider when using this oval-hole link with slotted mounting holes?+

Because actuation relies on oval-slot travel and slotted-hole alignment, assembly clearance and alignment tolerance matter to avoid binding. Validate clearance between the link and pins/bolts and verify that the configured oval-hole length and pitch S match the mating pattern so motion remains smooth across the full long-stroke range.
