Deep Groove Ball Bearings SKF 6307 -Z
The SKF 6307-Z single-row deep-groove ball bearing, measuring 35x80x21 mm and featuring a single-sided cover, offers robust protection against dirt particles.
The SKF 6307-Z deep groove ball bearing is a rolling bearing designed for industrial applications and repairs. With main dimensions of 35 mm inner diameter, 80 mm outer diameter and a width of 21 mm, this design is primarily designed to withstand radial forces as well as moderate axial forces. Manufactured from standard rolling-element bearing steel 100Cr6, the design is characterised by its dimensional stability. The sheet steel cage guides the rolling elements within a temperature range of -20 to +150 degrees.
What is the 6307-Z deep groove ball bearing suitable for in operation?
This deep-groove ball bearing is primarily used where rotating shafts are supported and one side of the housing is already protected. Typical applications include general industrial shaft mountings. The single-sided sheet metal cover leaves the open rear side accessible for lubricant circulation, whilst the closed side shields the interior of the bearing from coarse contaminants. This makes the bearing particularly suitable for housings with partial sealing.
What is the function of the single-sided Z cover plate on the 6307-Z deep groove ball bearing?
The -Z designation refers to a non-contacting cover plate made of profiled sheet steel on one end face. As the cover plate is non-contacting, this metal gap does not generate any additional friction during operation. With standard radial bearing clearance and tolerance class P0 (ABEC 1), the component is compatible with standard bearing seats. Before assembly, it is advisable to check the installation direction to ensure that the lubricant chamber in the housing is correctly aligned towards the open side of the bearing.
What are the dimensions of the 6307-Z deep-groove ball bearing?
This deep-groove ball bearing has an inside diameter of 35 mm, an outside diameter of 80 mm and a width of 21 mm. The outer ring is cylindrical in design and has neither a flange nor a ring groove. These standardised dimensions allow for direct replacement in standardised bearing housings and on corresponding shaft seats.
What does the suffix -Z mean in the designation of this roller bearing?
The suffix -Z denotes a single-sided, non-contacting cover plate made of sheet steel. It protects the interior of the bearing from coarse contaminants and prevents grease from escaping directly. As the cover plate runs past the inner ring without contact, no additional frictional resistance is generated, which promotes smooth running.
What is the clearance of the 6307-Z deep-groove ball bearing?
The bearing is manufactured with standard radial clearance. This design provides sufficient radial clearance for standard fits on the shaft and housing at normal operating temperatures. For installation situations involving significant heating or extreme press fits, however, a version with increased bearing clearance, such as C3, is recommended.
What is the temperature range for which the bearing is designed?
The permissible operating range is between -20 and +150 degrees Celsius. Both the 100Cr6 roller bearing steel and the sheet steel cage retain their dimensional stability within this temperature range. In the event of sustained high temperatures, ensure that a suitable lubricant is used which is approved for this temperature range.
What material are the cage and rings made of?
The inner and outer rings, as well as the rolling elements, are made from hardened standard roller bearing steel (100Cr6). A sheet steel cage is used to guide the balls. This component has no electrical insulation and complies with the standard tolerance class P0 or ABEC 1.
How is a single-sided bearing lubricated?
The open side of the bearing allows it to be filled directly with grease or connected to a central oil lubrication system. The closed side, with the Z-ring, typically faces outwards towards the dirty side. This ensures that the lubricant remains within the system whilst keeping out contaminants.
