4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.

Set appropriate shoulder diameter. -
- Note! Seals with housing also require screws to be tightened according to factory guidelines.

The hydrodynamic ribsa) provided in one direction on the air side face of the lip ensure higher sealing performance. Perfect Seal The hydrodynamic ribsa) provided in two directions on the air side face of the lip ensure higher sealing performance (higher sealing performance in both rotational directions of the shaft).

The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.

Oil seals are a crucial component in any high-pressure system, serving the important role of preventing leaks and maintaining the integrity of the system. These seals are designed to withstand the high pressures typically found in hydraulic systems, engines, compressors, and other machinery where oil leakage can cause serious damage.
- The dimensions 45x62x8 denote the outer diameter, inner diameter, and thickness of the oil seal, respectively. In this case, the outer diameter measures 45mm, the inner diameter stands at 62mm, and the thickness is 8mm. These measurements are critical as they determine the compatibility of the seal with different mechanical components, ensuring a snug fit and optimal performance.

Oil Gasket Seal:
Oil seal type or shape
Remove the pump fixing nuts or bolts. Pull the pump and gasket or gaskets off the engine.
NBR
O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.
Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
