Component supplier OPTIMAL has launched new wheel bearings with double-row ball bearings with improved 4 point seals for maximum protection and impermeability

Wheel bearings are exposed to particularly strong environmental influences, particularly on wet Irish roads. Quantities of salt, water and mud in winter and sand and dust in summer permeate the seals, shortening the lifespan of the wheel bearings. To combat this problem OPTMAL is now offering cassette seals with four sealing lips to boost the level of impermeability.

The new bearing offer several benefits; The 4 point seal provides better retention of bearing grease on the inside and gives added protection against water, sand and other dirt penetrating particles from the outside. The bearings also feature an extra metal plate which protects the sealing lips against adverse weather conditions. Added to this the bearing seals also feature acrylic nitrile butadiene rubber (NBR) which provides optimum resistance to oil, grease and other hydrocarbon compounds. This type of rubber remains elastic for longer and suffers less abrasive wear.

New double-row ball bearings from OPTIMAL are now available for around a third of the total car parc and the company will continuously update and extend coverage over the coming months.
