Secondly, the helical shape of the rod imparts a twisting motion to the bit as it rotates, which aids in maintaining a consistent cutting action. This reduces walking or drifting of the drill, ensuring more accurate hole placement This reduces walking or drifting of the drill, ensuring more accurate hole placement

- The dimensions 40x52x7 denote the outer diameter, inner diameter, and thickness of the oil seal respectively. The first number, 40, refers to the outer diameter, which is the measurement from one side of the seal to the other when it's placed on the outer surface of the component it seals. The middle number, 52, signifies the inner diameter, the size of the shaft or housing bore it fits around. Lastly, the 7mm thickness contributes to the seal's durability and ability to withstand pressure.
- Rotating shaft diameter
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.① - Oil Seal The Essential Component in Machinery Performance
