PU BUSH (YELLOW COLOUR) OD 65mm,ID 17.5mm, LENGTH 100mm

Description :PU BUSH (YELLOW COLOUR) OD 65mm,ID 17.5mm, LENGTH 100mm. Note: 1. Visual Inspecti on . Surface Finish: Inspect for cracks, pits, or air bubbles (voids) which can lead to premature failure under compression. . Edges: Ensure clean-cut edges without fraying or burrs that could interfere with the punch m ovement. 2. Dimensional Verification Use calibrated digital vernier calipers or micrometers to check against the design specifications: . Inner Diameter (ID): Must allow a snug fit over the punch without binding. . Oute r Diameter (OD): Should fit the housing/pocket correctly to allow for natural bulging during compression. . L ength/Height: Consistency across a batch is critical for uniform stripping force. 3. Mechanical & Material Tes ting . Hardness Test: Use a Shore A durometer. Acceptance typically requires a reading of 90 Shore A (+/_5 ) for standard industrial punch strippers. . Compression/Permanent Set: . Compress the bush to its maximu m recommended stroke (typically 25%-30%) for a set duration. . Acceptance Criteria: After releasing the lo ad, the bush should return to its original height. A permanent set (creep) of more than 5%-8% after initial c ycles may be cause for rejection. . Stiffness Variation: The percentage variation in stiffness before and after test cycles should generally remain within 20% of the original value. 4. Advanced Verification (Batch Accept ance) . Oil & Chemical Resistance: For high-volume production, submerge a sample in the lubricant used in the press for 24 hours. The material should not swell or become brittle.
