  • When a seal is angularly misaligned – or cocked on the shaft – an irreversible process begins. Excessive pressure on one section of the seal, when not installed properly, can cause the spring to become dislodged or the seal to heat up and become brittle through excessive wear, both leading to a premature failure.

  • An oil seal, also known as a rotary shaft seal, is a critical element in any machinery with rotating parts, including a rotavator. It serves as a barrier, preventing oil or other lubricants from leaking out while inhibiting dirt and debris from entering the internal mechanisms. In the context of a rotavator, the oil seal ensures that the lubricating oil stays within the transmission system, reducing friction and preventing wear and tear.
