ARIETE ARI.058 - PAIR OF FORK OIL SEALS 39 X 51 X 8/10,5 TCL

ARI- THE ORIGINAL FORK OIL SEALS, custom-made for your fork

Ariete fork oil seals are different! The quality of their execution is matched by the unique nature of the material used: the carboxylated elastomer known as XNBR.

This compound offers unique characteristics of resistance to abrasion, to high temperatures, and to the complex lubricants with numerous additives, which are used in modern forks as fitted to motorcycles and scooters.

The reciprocating action of the fork tube against the seal subjects it to a notable degree of abrasion, which is complicated by the heat generated as a result of hydraulic displacement within the fork, plus the friction of the components involved. This mechanical wear and tear leads to accelerated ageing of the rubber which is also obliged to deal with the chemical action of the various additives in the lubricant.

Oil seals are normally made from a nitrile rubber, known as NBR. This is used because it is cheap, and plentiful, not because NBR is the best material for the job.

Ariete technical staff have accumulated 70 years of experience in the rubber industry, and have spent many years looking for a better material for the manufacture of oil seals.

Although the cost of XNBR is almost twice that of NBR, the sophisticated technology used to make Ariete oil seals enables them to be put on the market at highly competitive prices. In this way, the Ariete Customer enjoys the benefits of a very high quality product, which satisfies the most demanding requirements, at a competitive price.

ARISIL special oil seal lubricant ARI fork oil seals are made from a rubber compound specifically developed to work with the lubricants used in front forks, with all their various additives. This compound is completely different from that normally used for rotating shaft seals, since the physical environment inside a fork with its reciprocating movement, and the specialist lubricants, are completely different. Ariete have designed ARI oil seals with a variety of lip profiles to make them longer lasting, while reducing to a minimum the friction effect against the moving shaft. Over the years, Ariete have discovered the key role of a separating lubricant between the fork tube and the rubber of the oil seal to reduce to a minimum the surface friction, without affecting the function of the oil seal. After exhaustive testing, Ariete have chosen a lubricant which is produced in the USA, and devised specifically as a rubber/metal lubricant for mechanical components used in the NASA space program. The advantage of this special grease, which they call ARISIL, is that it extends the life of the oil seal, and helps it retain its vital characteristics of flexibility and chemical resistance. For this reason, every set of ARI FORK OIL SEALS contains a single dose sachet of ARISIL, sufficient to lubricate the two oil seals supplied.
