Corteco is a well-known brand in the automotive industry, supplying top-quality oil seals, including the first Simmerring® in 1929. The range consists of more than 7000 gaskets and more than 6500 OE-quality shaft and valve stem seals.
Description
Heavy Duty Wheel Seals and Agricultural Equipment Seals can be divided into AP type, CRS type and ST type. Mainly be used in heavy pollution of agricultural machinery, construction machinery, mining equipment and trucks, buses and other environments. Compared to TC type, with special internal lubrication design, making it closed to the rotary shaft seal and bearing assembly which prevent external dirt effectively; a specially designed multi-lip inside the seal, makes it to achieve the function. Multiple external sealing lip design effectively prevents outside dirt and grease leakage immersion; the internal high-quality grease (butter) prevents muddy and water immersion.
Several variables must be considered when selecting oil seals. The physical dimensions and materials will vary depending on the environment of use. In addition, oil seals must remain lightweight, compact, and exhibit high self-lubrication performance.
Pour-point depressants: This additive has nothing to do the actual pouring of your oil. In fact, pour-point depressants help prevent the wax particles in the oil from hardening in cold conditions. As a result, the motor oil flows freely even in low, cold temperatures and the engine doesn’t need to work any harder to pump it.

Rotary shaft or oil seals are placed between moving and stationary pieces of machinery to ensure that contaminants, moisture, corrosive materials and abrasives do not damage the various components. They can also prevent unwanted mixing of fluids, including water and oil combining within a machine.
What are Oil Seals – A guide to Oil and Rotary Shaft Seals
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).

However, when you actually select the oil seal to use, the most important factors are past success history and points of improvement, so it is not necessary to follow this order to the letter.
Some distributors can be removed without separating the gears, and so the arm does not turn.
