Bearing Seals
Bearing Seals, also known as grease seals, are used to protect tapered, spherical, cylindrical and double-row bearings from excess grease loss and contamination. In 1956, Clark Seals partnered with The Timken Company to develop the industry’s first precision bearings seals for tapered roller bearings. Over the years, Clark Seals has pioneered many significant advancements in bearing seal design and manufacturing technology, including the industry’s first sheave and excluder bearing seals, unitized zero-friction bearing seals, hand-install bearing seals and vacuum molding technology, a technology that revolutionized seal manufacturing.
Some seals are integral to the bearing; others aren’t. The focus here is on what to consider when selecting external bearing seals. Key factors in making the right choice for an application typically include:Bearing type (rolling or sleeve),Lubricant (oil or grease),Seal friction and consequent heating.Shaft surface speed and finish,Physical space available.To select the appropriate seal for an application, match the relevant factors from the above list with the characteristics of the following external seal types.
