Deep Groove Ball Bearings FAG 608 -2Z-C3
The FAG 608 -2Z-C3 deep-groove ball bearing features compact dimensions of 8x22x7 mm, sheet metal shields on both sides and increased C3 clearance for rotations subject to thermal stress.
The FAG 608 -2Z-C3 deep groove ball bearing is a single-row radial ball bearing made from 100Cr6 rolling bearing steel, designed for compact shaft diameters. This miniature bearing accommodates radial forces as well as axial loads in both directions. The design complies with tolerance class P0 (ABEC 1) and features a dimensionally stable sheet steel cage. Thanks to its double-sided protection with non-contact cover plates, this rolling bearing is suitable for applications where low frictional resistance and protection against coarse dirt particles are required simultaneously.
What is the 608 -2Z-C3 miniature bearing suitable for in operation?
Compact drives, precision mechanical mountings and high-speed shafts are typical areas of application. With dimensions of 8 mm bore, 22 mm outer diameter and 7 mm width, the bearing fits into confined installation spaces. Compared to sealing lips that rub against the bearing, the non-contacting 2Z cover plates do not generate any additional frictional torque. In designs operating at higher speeds, this construction promotes low-friction operation, whilst ensuring that the lubricant remains within the bearing chamber and solid contaminants are kept out.
What advantages does the C3 bearing clearance offer in your design?
The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This additional operating clearance compensates for thermal expansion when the inner ring and shaft heat up more than the housing during operation. Even with tight press fits, this clearance helps to prevent the rolling elements from becoming stressed. In combination with the permissible temperature range of -30 to +120 degrees, this variant offers a high level of operational reliability under varying thermal environmental conditions.
What are the dimensions of the 608-2Z-C3 deep-groove ball bearing?
The main dimensions are 8 mm internal diameter (bore), 22 mm external diameter and 7 mm overall width. The outer ring is cylindrical in design and has neither a flange nor a ring groove. Thanks to these standardised dimensions, the single-row component can be fitted precisely into cylindrical housing bores.
What does the suffix ‘2Z’ mean for this FAG bearing?
The abbreviation 2Z refers to cover plates made of profiled sheet steel, fitted on both sides. These gap covers protect the raceway from the ingress of dust and foreign particles. As the shields do not come into contact with the inner ring, no frictional heat is generated during operation, which helps to ensure smooth running at higher speeds.
Why is bearing clearance class C3 appropriate for the 608 deep-groove ball bearing?
Increased radial bearing clearance of class C3 prevents the bearing from seizing after it has been pressed onto the shaft or when it heats up. If the shaft expands during operation, the internal clearance is reduced. The C3 radial clearance helps to ensure that the rolling elements continue to roll freely.
What is the temperature range for which the bearing is designed?
The permissible operating range is between -30 and +120 degrees Celsius. The components made from standard roller bearing steel 100Cr6 and the guided sheet steel cage retain their dimensional stability within this temperature range. A lubricant suitable for this range is essential for reliable operation.
What material are the cage and rolling elements made of?
The rolling elements and the bearing rings are manufactured from through-hardened standard roller bearing steel. A robust sheet steel cage is used to guide the balls. This combination offers high fatigue strength under alternating radial and axial loads, but does not feature integrated electrical insulation.
What is the tolerance class of this ball bearing?
The bearing is manufactured to tolerance class P0, also known as standard tolerance PN or ABEC 1. This accuracy class meets the usual requirements in general mechanical engineering and ensures a dimensionally accurate fit on ground shafts and in finely machined housing seats.
