Plain Guide Bushings for Die Sets LDB

Plain guide bushings are used inside die sets to maintain die-to-die alignment during closing and repeatable leader motion. In automotive and industrial stamping tooling, they support long guide travel where stable centering and smooth sliding help reduce wear on mating leader elements.

The oil groove variant supports lubrication film retention, which is beneficial when cycles are frequent and boundary lubrication may occur at the contact interface. For assembly types that experience micro-misalignment from handling or repeated changeovers, the Loctite adhesive bonding approach improves installation stability so the bushing stays properly positioned in the die insert pocket.

• Automotive connector and bracket stamping die sets requiring consistent die positioning
• General-purpose progressive dies where long guide travel supports repeatable centering
• Die sets that benefit from adhesive-assisted retention to limit bushing shift

The provided product metadata specifies the functional features (oil groove and Loctite adhesive bonding) and dimensional ranges, but it does not include the exact steel grade or heat-treatment state. Therefore, heat treatment, hardness (HRC), and wear/toughness trade-offs cannot be stated from the supplied data.

For proper materials selection in die-set guide applications, engineers typically match the bushing and mating leader materials to expected load, wear rate, and lubrication conditions. The oil groove feature is generally used to enhance lubrication retention at the sliding interface, improving wear behavior under cyclic movement.

• Manufacturing emphasis: Oil-groove machining plus adhesive bonding for positional stability

Select the bushing by matching the leader diameter and the die-set pocket geometry. The key inner diameter is d = 20 ~ 60 mm; choose the value that corresponds to the mating leader shaft diameter for proper guidance clearance.

Then select the full length based on the required guide engagement. Available full-length alteration ranges include L = 50, 50~60, 60~80, 80~100, 100~120 mm and LC = 25 ~ 121 mm. Use the length that provides adequate bearing/support along the leader during the full stroke.

• d (20–60 mm): match to leader shaft diameter class
• L (50–120 mm): match to required guide engagement length
• LC (25–121 mm): confirm it aligns with the designed alteration/step length in the die housing

Tolerance/fit considerations depend on the mating leader and the die bore tolerances, but the dimension ranges above define what sizes are available for selection. For adhesive-bonded retention, ensure the bushing seats consistently in the pocket so adhesive thickness and curing do not shift the guide axis.
