25 40 7 seal
The primary function of the 20x35x7 oil seal is to prevent the escape of lubricants from one chamber to another, ensuring that machinery operates smoothly and efficiently
. By sealing the gaps between moving parts, the oil seal helps in minimizing friction and wear, contributing to the longevity of equipment. Moreover, preventing oil leakage is crucial for maintaining proper lubrication levels, thereby supporting optimal operational conditions and reducing potential breakdowns.

One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

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.
