G25x35x4 INA rotary shaft seal thin oil seal

Main description

G 25x35x4 INA is a compact rotary shaft seal designed for sealing rotating shafts in confined mechanical assemblies, ensuring reliable protection against oil leakage and external contamination.

Within the rotary shaft seals INA oil seals category, this model stands out due to its reduced width of only 4 mm, making it ideal for applications where installation space is limited. The seal operates at the interface between the shaft and housing, maintaining tight sealing even at higher rotational speeds.

This INA oil seal is engineered to provide consistent performance in dynamic conditions, preventing lubricant loss while protecting internal components from dust, dirt, and environmental factors. Its compact design makes it a preferred solution in precision mechanical systems and lightweight industrial assemblies.
