Product Guide
Application Scenarios+
This heavy-load, ultra-compact ball lock retainer is used in punch tooling within injection mold and press-related forming stations where punch retention must withstand high tensile forces. The compact geometry is especially valuable in tools with limited axial space, helping maintain proper punch alignment without increasing cavity size.
- Automotive connector and bracket tooling: Use when punch sets experience repeated high-pressure forming cycles. The retention design resists shift under tensile stress to help preserve consistent formed features.
- Thick-gauge part forming and high-pressure operations: Suitable for applications requiring secure end retention to prevent punch end play during load peaks.
- Tight die cavities and multi-cavity layouts: The space-saving form factor supports efficient assembly while maintaining reliable workholding for punch components.
Choose this variant for dependable end retention in robust punch tooling; its applicability to punch diameters of 10–40 mm aligns well with common heavy-duty tooling dimensions.
Material & Process Details+
The provided product data does not specify a steel grade, hardness (HRC), heat-treatment state, or coating for this DAYTON ball lock retainer. For that reason, material-property statements like quenched & tempered hardness, nitriding, or wear-resistance vs. toughness trade-offs cannot be confirmed from the supplied specifications.
When qualifying retainers for heavy-load punch tooling, mold and die engineers typically verify the manufacturer’s documentation for:
- Material/grade (e.g., tool steels vs. stainless/low-alloy alternatives)
- Heat treatment condition (pre-hardened, through-hardened, or case-treated such as nitriding)
- Hardness target (HRC) for surface wear and load-bearing surfaces
- Compatibility with the punch steel grade and expected cycle fatigue
If you share the material/heat-treatment spec for this SKU, this section can be updated with precise grade-to-equivalent and HRC values.
Sizing & Selection Guide+
Select the retainer based on the applicable punch diameter (D) from the specification range. This product supports punches with D = 10–40 mm.
How to match it to your mold/punch layout:
- Step 1: Measure the punch diameter at the retention end (use the nominal punch diameter that the tooling standard calls out).
- Step 2: Confirm that the punch diameter falls within 10–40 mm. If it is near a boundary, verify the actual manufacturing tolerance of the punch diameter.
- Step 3: Check clearance/pack height in your die/tool stack-up. The “ultra-compact” design is intended for limited-space assemblies where conventional retainers may reduce alignment reliability.
- Step 4: Verify fit conceptually: the retainer must provide end retention without introducing lateral play that can cause punch shift under heavy loads.
No additional adjustable dimensions or tolerance values were provided in the input data, so dimension-by-dimension tolerance matching should follow your punch manufacturer’s drawing and the retainer’s datasheet for this specific SKU.
Frequently Asked Questions
What punch diameter range is compatible with this heavy-load ball lock retainer?+
Compatibility is defined by the applicable punch diameter (D) range of 10–40 mm. Ensure the punch diameter used in your punch set falls within this interval at the retention end. If you operate near the range limits, confirm the punch diameter tolerance from the punch drawing to maintain reliable retention fit.
How does the compact design help in punch tooling for injection molding-related forming operations?+
The retainers are specified as ultra-compact with an engineered geometry intended for limited space assemblies. In practical tool builds, this supports efficient assembly without increasing the tool envelope. It also helps maintain punch alignment by reducing packaging compromises that can lead to shift during heavy loading.
Is this retainer intended for heavy tensile and high-load conditions?+
Yes. The product description specifies heavy-load use with secure end retention designed to resist shift under heavy loads and tensile stresses. This makes it suitable for punch sets used in robust forming and high-pressure operations. Final qualification should still account for your cycle load and punch material behavior.
Do you provide the steel grade and hardness (HRC) for this DAYTON retainer?+
The supplied product data does not include a specific steel grade, heat-treatment state, or hardness (HRC) values. Because of that, hardness/heat-treatment claims cannot be verified from the current inputs. Please provide the datasheet material section for series code 250000002256 if you need grade equivalence or hardness targets for your engineering review.
How should I check retention fit to prevent punch end play?+
Use the defined D = 10–40 mm range to confirm the punch diameter matches. Then verify clearance in the tool stack-up to avoid over-constraining or allowing lateral movement at the retention end. Since no tolerance values were included in the provided data, use the punch and retainer drawings to confirm actual fit and play under your expected heavy load cycle.
