LRK Standard Locating Rings - Large Diameter Type, 2-Bolt Holes

These large-diameter locating rings are used in injection mold base assemblies to control the repeatability of mold alignment during clamp and open cycles, especially in thin-wall mold layouts where base space is limited.

• Automotive and appliance thin-wall parts: Pair the ring’s bolt-stopper style mounting with 2-bolt holes to resist shift under cyclic loading, helping maintain gating and ejector positional accuracy across production runs.
• Housing and cover molds with large register features: The large outer diameter variant supports stable registration and reduces sensitivity to minor base wear, improving part-to-part consistency.
• Multi-cavity or stacked layouts: When you need controlled retention and predictable locating behavior, the 2-bolt hole configuration provides a straightforward mechanical reference for locating systems.

Choose this LRK large-diameter, 2-bolt-hole variant when your alignment strategy must be compact yet robust for stable positioning.

The provided product data does not specify the steel grade or heat treatment state. Because locating rings are alignment-critical components, they are typically manufactured from mold steels and then processed for dimensional stability and wear resistance; however, the exact grade, hardness (HRC), and heat treatment (e.g., quenched & tempered or nitrided) are not listed for this SKU.

To select the correct wear/toughness balance, confirm the material specification for series code 110200080770 with your supplier or incoming inspection documents. If different material options exist within the broader LRK family, compare them by:

• Hardness (HRC): Higher hardness improves wear resistance under frequent clamping cycles.
• Toughness trade-off: Over-hardening can reduce impact toughness—important if your mold sees occasional shock loads.
• Surface treatment: Nitriding or similar treatments can improve surface wear without fully sacrificing core toughness.

For compliance with your tooling spec, verify grade and treatment before final design freeze.

Use the locating ring outer diameter D to match your mold base’s locating geometry and registration requirements. This SKU is specified for D = 100 mm or D = 120 mm.

• Step 1 (outer diameter match): Select the variant whose D provides the correct engagement with your locating register surfaces in the cavity/core base layout.
• Step 2 (bolt retention compatibility): Ensure the mounting interface is designed for the 2-bolt holes bolt-stopper style retention, so the ring seats and resists rotational/axial shift during clamping.
• Step 3 (fit & tolerance): Maintain the locating system’s intended clearance or interference per your mold standard. Because the tolerance values are not provided in the data, confirm required fit tolerances in your drawing/spec documentation before machining.

Configurable aspect: D is available in 100 and 120 mm; the 2-bolt-hole layout is the fixed feature for this series.
