For the Pop Release bearing unit, this takes place at the same time as lubrication of the bearing through the grease nipple mounted on the bearing housing. Labyrinth seals are a non-contact seal that makes a tougher path for contaminants to enter while operating with little or no friction. This SKF ready-to-mount pillow block housing with inch dimensions has a housing made of steel and has four mounting bolts, a spherical roller bearing insert, and labyrinth seals. Demands on the seal were high, requiring a seal able to perform effectively even if the shaft is misaligned up to 1.5 degrees. After rigorous tests at the SKF laboratory in King of Prussia, Pennsylvania, the seal design found to be best suited is that shown in figures 1 and 2. FIG. The foreign matter will also be subjected to centrifugal force due to circulation movement around the flared portion. FIG. Sealing effectiveness increases with the number of washer sets and can be further improved by incorporating flocked washers. The lathe has now given more than a year of trouble-free service. Recently, SKF introduced the Generalized Bearing Life Model (GBLM) concept for rolling bearings [1]. The seal is reinforced with an outer sheet guard to enable it to withstand environments which are highly contaminated with hard and abrasive particles, such as gravel, sand and wood chips. Most PTFE seals are supported by metal springs or elastomeric rings to assure good shaft contact. At least a portion of the passageway is defined by frusto conical surfaces on the annular tongues arranged to exert centrifugal force on any foreign matter in the passageway upon relative rotation between the two members so as to urge the foreign matter towards the outer end of the passageway. Sudarsan Engineering Industries. As a result, the maximum permissible rotational speed of the bearing is also restricted. Alternatively, in the end cap bearing assembly of FIG.

Multi-stage axial labyrinth cartridge seal – includes two labyrinth rings, an internal low friction V-ring seal and provision for grease purging. Since the maximum operating temperature that the seal materials and the grease in the bearing can withstand is around 100 –C, the peripheral speed at the seal contact point, i.e. & Terms of Use. 7 comprises a housing 70 fitted with a ball bearing 11, and an end cover 71 which co-operates with the housing to form an annular labyrinth passageway 72 therebetween. & Terms of Use. SKF installation instruction animation to explain the easy installation of HRS and HSS split seals in wind turbine main shafts step by step. To ensure that the width of the open end 51 is not smaller than that of the remainder of the flared portion 53 angle between the frusto-conical surface 54 and the axis of the housing is greater than the angle between the frusto-conical surface 55 and the axis of the end cover, so that the surfaces 54, 55 diverge away from each other in the direction towards the open end 51 of the passageway as shown in FIG. The foreign matter would of course also be subjected to centrifugal force due to circulation movement around the flared portion. Seal selection depends on many factors, including operating speed and temperature, required service life, and level of potential contamination. For the last 110+ years, CR Seals has been setting performance and service life standards for industrial and automotive shaft seals. This SKF labyrinth (triple ring) seal is designed for use with mounted SAF-series pillow blocks. A non-contact labyrinth seal is a type of mechanical seal designed by layering together metal sealing plates that combine to form a bunch of angles in a “maze-like” pattern. FIG. LABYRINTH SEALS (LO) Labyrinth seals are made up of a single metal ring component that interconnects with the grooves in the housing to form a labyrinth gap. 10 is an end elevation view of the end cap bearing assembly of FIG. The flared portions of the passageway are however not for the purpose of avoiding any diverging of the walls from the mouth in the event of tilting of the seal members when the shaft is under load, but for the purpose of obtaining a rubbing seal between the tongues when the two seal members are moved towards one another. The seal consists of three parts which are made of sheet steel and are pressed together. 11 is a cross sectional side elevation of an end cap bearing assembly incorporating another construction of labyrinth seal adapted to operate as a positive displacement pump to eject foreign matter, and. 11 and 12 comprises a housing 130 fitted with a ball bearing 11, and an end cover 131 which co-operates with housing 130 to form an annular labyrinth passageway between two annular tongues 132, 133 on the housing interleaved with two annular tongues 134, 135 on the end cover. The end cap assembly of FIG. The end cap bearing assembly of FIG. A cylindrical sleeve 19 surrounds the wall 16 and is connected thereto at the end remote from the end wall 17 by an annular bight portion 20 of U-shaped cross section, to form a spring support for the end cap assembly. This complex maze-like pattern prevents contaminants and splashing liquids from hitting the bearing. Labyrinth seals that do not contact the shaft depend on a tortuous interface, fluid surface tension, and a pump-like design to prevent leakage. FIG. The housing 10 is made of a resilient plastics material, preferably glass fibre reinforced nylon, and comprises a cylindrical inner wall 15, a cylindrical outer wall 16 surrounding the inner wall 15, an end wall 17 integral with adjacent ends of the walls 15, 16, and a plurality of radial webs 18 spaced around the housing and extending between the inner and outer walls 15, 16, the webs 18 being integral with the walls 15, 16, 17. The centrifugal force is however sometimes insufficient to prevent foreign matter being drawn further into the passageway upon relative rotation between the two members of the seal. Fey labyrinth sealing rings are used as sealing elements for both rotating and static applications. Want to learn more about what is driving change in the engineering world? The present invention arose from the discovery that the phenomena of foreign matter being drawn further into the labyrinth passageway occurred when the walls of the passageway diverged slightly in the direction away from the outer end of the passageway, due possibly to a slight tilting of one or both of the members of the seal due to deflection of a supporting shaft under load, or due to accumulation of tolerance errors in manufacture. Support video describing how to dismantle the labyrinth seal on a FRITSCH Universal Cutting Mill PULVERISETTE 19. Labyrinth seals protect against contaminants while still being capable of relatively high operating speeds. The annular recess 45 between the tongue 38 and the cylindrical flange 39 on the cover is filled with grease for lubricating the bearing, the seal 13 preventing escape of the grease through the labyrinth. The new SKF Pop Release bearing unit has a reinforced labyrinth seal designed to give high performance while operating in heavily contaminated environments.Rubbing seals are the most common type of seals for bearings mounted in bearing housings. The end cover is supported on a shaft 73 engaged as a close sliding fit in the bore of the cylindrical flange 39. In prior known labyrinth seals of this kind, the two co-operating members are generally formed with annular co-axial tongues of rectangular section which are interleaved with one another to form an annular passageway of stepped formation, each step consisting of an axially extending portion and a radially extending portion. Its disadvantage is that the seal generates a great deal of heat due to the high frictional torque between the seal lips and the part with which they are in contact, such as the shaft. The end cap assembly is secured in position in the end of the roller tube, with the flange 21 abutting the end of the tube, by swaging the end of the roller tube radially inwards, that is reducing the diameter of the end of the roller tube by external pressure, so as to force the sleeve 19 against the ribs 24 on the housing as shown in FIG.
