Product details
VKEFOT TG4 type 240x270x15 mm heavy duty rotary shaft oil seal manufactured in Xingtai, China. TG4 oil seal adopts rigid metal outer case bonded with NBR nitrile rubber, built with double lip and garter spring.
Primary spring lip maintains constant contact pressure against the rotating shaft to prevent oil leakage. Secondary dust lip excludes dirt, sand and muddy contaminants, well suited for heavy-duty, dusty working environments. This TG4 240-270-15 NBR oil seal delivers stable sealing under medium pressure. It is widely applied on heavy truck axles, gearboxes, speed reducers and heavy industrial machinery rotary shafts. Max working pressure ≤0.08MPa, allowable shaft speed up to 10m/s, operating temperature -20℃ to +100℃. It is a robust aftermarket replacement seal for heavy vehicle and industrial equipment maintenance.
