Deep Groove Ball Bearings FAG 6215 -2Z-C3
The single-row deep-groove ball bearing 6215 -2Z-C3 from FAG Wälzlager, measuring 75 x 130 x 25 mm, features sheet metal shields on both sides and an increased C3 bearing clearance for demanding industrial applications.
The 6215 -2Z-C3 deep groove ball bearing is a single-row radial ball bearing to standard tolerance class P0/PN (ABEC 1), made from 100Cr6 rolling bearing steel. With dimensions of a 75 mm bore, 130 mm outside diameter and 25 mm width, the component primarily accommodates radial loads as well as moderate axial loads. Thanks to the sturdy sheet steel cage and the metal end shields on both sides, the interior remains protected from coarse particles. For design and maintenance purposes, this bearing is a functional component in general mechanical engineering.
In which applications does the 6215 -2Z-C3 deep groove ball bearing prove its worth?
Drive systems and rotating shafts in industrial environments are among the typical applications for this deep-groove ball bearing. The gap seals on both sides (2Z) operate without contact, meaning no additional frictional heat is generated. This design is therefore suitable for applications involving higher speeds where there is no direct contact with splashing water. With a permissible temperature range of –30 to +120 degrees Celsius, the bearing can be used in enclosed assemblies subject to operational temperature fluctuations.
What are the advantages of the increased C3 bearing clearance during assembly?
The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance compensates for any reduction in diameter that occurs when the inner ring is pressed onto the shaft. Furthermore, the increased bearing clearance compensates for thermal expansion between the shaft and the bearing housing during operation, without the rolling elements becoming stressed. In the event of fluctuating operating temperatures, this helps to ensure low-vibration operation.
What are the technical features of the 6215 -2Z-C3 deep-groove ball bearing?
This single-row deep-groove ball bearing has a 75 mm bore, an outer diameter of 130 mm and a width of 25 mm. Manufactured from 100Cr6 rolling-bearing steel with a sheet steel cage, it combines sheet metal end plates on both sides with an increased C3 clearance. It accommodates radial loads as well as axial guidance forces and operates within a temperature range of -30 to +120 degrees Celsius.
What does the suffix combination -2Z mean?
The designation 2Z refers to cover plates made of profiled sheet steel fitted on both sides. These gap seals keep coarse dirt particles away from the raceways. As the sheet metal plates operate without contact, no additional frictional torque is generated. This allows for higher speeds compared with bearings fitted with sliding seals.
Why is the C3 bearing clearance advantageous for size 6215?
The designation C3 indicates a radial operating clearance in addition to the standard bearing clearance. This design prevents the balls from becoming jammed if tight fits on the shaft cause the inner ring to expand, or if temperature differences occur between the rotating shaft and the housing. The increased clearance ensures smooth running under thermal stress.
What materials are rings and rolling elements made of?
The inner ring, outer ring and rolling elements are made from standard roller bearing steel 100Cr6. This material is characterised by high strength and resistance to fatigue under rolling contact. A sheet steel cage guides the balls evenly and remains mechanically stable up to an operating temperature of +120 degrees Celsius.
What level of accuracy does tolerance class P0 or ABEC 1 offer?
The P0/PN or ABEC 1 classification corresponds to the standard tolerance class. It defines the permissible deviations in dimensions, roundness and axial run-out for the shaft and housing seat. For standard applications in general mechanical engineering, this precision grade ensures a precise fit when the bearing is fitted correctly.
What operating conditions does the temperature range of -30 to +120 degrees cover?
This temperature range covers the range within which roller bearing steel, sheet steel cages and split seals retain their functionality. It covers both cold starts at low ambient temperatures and the typical operational heating that occurs in enclosed mechanical assemblies, without the material undergoing any thermal microstructural changes.
