When selecting materials for wiper seals, factors such as temperature range, chemical exposure, and the physical environment must be considered to ensure optimal performance
. Proper material selection not only improves the durability of the seals but also enhances the reliability of the entire system.wiper seal



Next, we discuss the 40% figure, which can denote the allowable leakage rate for particular types of oil seals. Leakage can severely impact the overall performance of mechanical systems, leading to reduced lubrication and increased wear on components. A reputable oil seal must minimize leakage to a level that is often benchmarked at around 40% of the maximum allowable threshold for that system. Manufacturers pour significant resources into developing materials and designs that can achieve this standard, as minimizing leakage not only conserves lubricant but also enhances the efficiency and longevity of the machinery.

Maraming dahilan kung bakit nagiging sanhi ng paghahatak ang mga drums ng preno. Ang isa sa mga pangunahing dahilan ay ang hindi wastong pagsasaayos ng preno. Kung ang mga pad ng preno ay hindi maayos na nakaposisyon, maaari silang manatiling naka-contact sa drum kahit na ang preno ay hindi ginagalaw. Bukod dito, ang kontaminasyon mula sa langis o tubig sa mga pad ng preno ay maaari ring magdulot ng pagkakadulas, na nagreresulta sa paghahatak.
