Manufacturing flexibility . © 2020 Efficient Plant. A general rule of thumb suggests that labyrinth seal clearance should be 0.002” – 0.004” (.050 – .100 mm) greater than the sleeve bearing clearance. While longer service life is one of the primary targets, SKF has also focused on other customer requirements. Such seals afford more protection than individual contact or non-contact seals. In addition, a very low running temperature (or low friction or low power losses) is very important, as excessive temperature on the handles can create problems for end users ( .9). The sinusoidal form of the SKF WAVE lip con- siderably extends the path on the … Your proven service leader with reliable delivery since 1972. Non-contact seals: A non-contact seal (Fig. Unfortunately, non-contact seals also allow lubricant to leak out of the bearing chamber and liquid, and permit physically small contaminants to enter. Testing and analysis . Key factors in making the right choice for an application typically include: 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. EASA is an international trade association of more than 1900 firms in 62 countries that sell and service electrical, electronic and mechanical apparatus. Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Radial slots in the tapered attachment. SKF bearings and seals are utilized by many well-known carmakers as original parts, while the brand also offers them on the aftermarket. The bearing is washed with a hot water flow at more than 100 bars from the pump. Part of this work is illustrated in .5(strain distribution inside a RSL seal lip area) and .6(contact force versus axial interference). Bearing performance is evaluated as above. Elastomers . No one knows how seals work with bearings better. Bearing interfaces . Suggested clearances for labyrinth seals with oil-lubricated sleeve bearings are provided in Table I: Speeds given are synchronous speeds corresponding to the applicable line frequency and winding poles.
