Deep Groove Ball Bearings SKF 6002 -Z/C3
The SKF 6002 -Z/C3 deep groove ball bearing combines compact dimensions of 15x32x9 mm with increased C3 clearance and single-sided dust shielding for demanding industrial drives.
The SKF 6002 -Z/C3 deep groove ball bearing is a single-row rolling bearing made from hardened bearing steel (100Cr6) in the Explorer design. With a bore of 15 mm, an outside diameter of 32 mm and a width of 9 mm, this design is suitable for withstanding radial and moderate axial loads in both directions. The single-sided sheet metal cover protects the bearing’s interior from coarse contamination, whilst the opposite open side allows for targeted relubrication within the housing. Design engineers and maintenance personnel rely on this bearing when installation space is limited.
What are the industrial applications for the 6002 -Z/C3 deep groove ball bearing?
Compact shaft mountings benefit from the 6002 -Z/C3 deep groove ball bearing wherever operational heating or tight fits occur. The increased radial clearance compensates for thermal expansion during operation. Together with the sheet steel cage and the temperature range of -20 to +150 degrees, the bearing is designed for demanding industrial applications. The single-sided Z-cover plate keeps foreign matter out whilst allowing lubricant to be supplied via the housing.
What are the advantages of C3 bearing clearance and tolerance class P6/P5?
The C3 designation indicates a larger radial clearance than the standard. This ensures that sufficient clearance remains between the raceways during hot operation, which prevents premature seizing. The P6 dimensional accuracy and P5 running accuracy classifications contribute to low vibration levels and precise concentricity. The SKF Explorer design is characterised by tight manufacturing tolerances and is suitable for both series production and repairs.
What are the dimensions of the 6002 -Z/C3 deep-groove ball bearing?
This roller bearing has an inside diameter of 15 mm, an outside diameter of 32 mm and a width of 9 mm. The outer ring is cylindrical in design and has no flanges or ring grooves. Thanks to these standardised key dimensions, the component can be fitted quickly into existing bearing housings or shaft seats.
What does the suffix -Z/C3 mean for this bearing?
The letter Z denotes a cover plate made of profiled sheet steel, fitted on one side, which provides a contactless seal and keeps out dirt. The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This combination protects the internal components from particles, allows lubricant access from the open side and withstands higher operating temperatures.
Within what temperature range can the bearing be operated?
The component is designed for ambient temperatures between -20 and +150 degrees Celsius. Both the 100Cr6 rolling bearing steel used and the riveted sheet steel cage retain their strength within this temperature range. At higher operating temperatures, it is advisable to use a heat-resistant lubricant, which can be replenished via the open bearing side.
What do the tolerance classes P6 and P5 mean?
This classification means that the dimensional accuracy corresponds to tolerance class P6 and the running accuracy to class P5. Both classes have tighter tolerances than the standard ‘Normal’ (PN) class. This helps to reduce vibrations at higher speeds and protects adjacent drive components.
Why is the bearing only covered on one side?
A single-sided Z-ring protects the rolling elements from external contamination, whilst leaving the rear side exposed for contact with the machine’s internal lubrication system. This is particularly suitable for use in gearboxes or oil circuits where the bearing is continuously supplied with the existing gearbox oil or grease.
What materials are rings and rolling elements made of?
Both the solid rings and the balls are made from through-hardened standard roller bearing steel of the 100Cr6 grade. This material withstands high contact pressures and offers high wear resistance. A lightweight, vibration-resistant sheet steel cage is used to guide the rolling elements; it is fitted without the need for additional electrical insulation.
