Deep Groove Ball Bearings FAG 6018 -2RSR
The 6018 -2RSR deep groove ball bearing from FAG Wälzlager, with dimensions of 90x140x24 mm, offers effective protection against dirt under predominantly radial loads.
The 6018-2RSR deep groove ball bearing from FAG Rolling Bearings is a single-row radial ball bearing for shafts with a diameter of 90 mm. As a versatile rolling bearing, this component accommodates radial loads as well as moderate axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6 and fitted with a robust sheet steel cage, the bearing operates with a standard radial clearance. Thanks to its sealed design with contact seals, the bearing is suitable for direct installation in machinery, drives and industrial plant.
In which environments is the 6018-2RSR deep groove ball bearing used?
The 6018 -2RSR deep groove ball bearing is particularly suitable for industrial applications involving continuous radial loads and environments with high levels of contamination. Typical areas of application include general mechanical engineering and industrial drive systems. As the contact seals reduce the ingress of dust and moisture, the design protects sensitive raceways even under demanding conditions. At the same time, the symmetrical geometry of the raceways contributes to smooth running.
What are the distinctive features of the 2RSR seal on this deep-groove ball bearing?
The 2RSR seal, which contacts the shaft on both sides, seals the bearing against the outside environment and retains the lubricant inside the bearing. This eliminates the need for additional external sealing elements on the shaft during design and assembly. Furthermore, the seal arrangement protects the rolling elements from particles and splash water. When specifying the bearing, the permissible temperature range of -20 to +100 degrees and the tolerance class P0/PN (ABEC 1) must be taken into account. For bearing locations subject to high thermal loads, it should be checked in advance whether the standard bearing clearance is sufficient for the operating conditions.
What are the dimensions of the 6018-2RSR deep-groove ball bearing?
With a bore diameter of 90 mm, an outer diameter of 140 mm and a width of 24 mm, the bearing complies with standardised mounting dimensions. The outer ring is cylindrical, with no flange or groove. This single-row roller bearing can be fitted onto suitable 90 mm shafts and into corresponding housing bores.
What does the suffix code -2RSR mean?
The -2RSR design is characterised by sliding sealing lips fitted on both sides. These contact seals rest against the shoulders of the inner ring and help to retain grease inside the bearing whilst making it more difficult for dirt and moisture to penetrate. The sliding contact generates friction, which reduces the limiting speed compared with open bearings.
What is the temperature range for which the roller bearing is designed?
Operating temperatures between -20 and +100 degrees are permissible for this bearing. This range is limited by the material of the sliding seals and the bearing lubrication. Within this temperature range, the sealing lips retain their sealing effectiveness, whilst the sheet steel cage reliably guides the rolling elements, made from 100Cr6 bearing steel, along the raceways.
What does the tolerance class P0/PN or ABEC 1 mean?
P0, PN or ABEC 1 denote the standard tolerance for dimensional and running accuracy in rolling bearings. This accuracy class covers standard applications in general industrial and mechanical engineering where no above-average manufacturing tolerances or high-precision concentricity requirements are specified.
What is the characteristic feature of the standard radial bearing clearance in this bearing?
A balanced operating clearance between the rolling elements and raceways when the bearing is unmounted characterises the normal radial bearing clearance. With standard fits on the 90 mm shaft, this clearance is reduced after installation to such an extent that it promotes low-vibration, smooth running during operation without any unacceptable seizing.
Which cage guides the rolling elements in the 6018-2RSR deep-groove ball bearing?
A sheet steel cage guides the rolling elements, which are arranged in a single row, and maintains a uniform spacing between the balls. This cage design is rated for operating temperatures up to +100 degrees, is lightweight and is resistant to common lubricants.
