Deep Groove Ball Bearings SKF 6040 M
The SKF 6040 M deep groove ball bearing, with a 200 mm bore and a brass cage, provides a robust bearing solution for demanding industrial drives in heavy machinery manufacturing.
The SKF 6040 M single-row deep groove ball bearing is designed for predominantly radial loads as well as moderate axial forces in both directions. With an inside diameter of 200 mm, an outside diameter of 310 mm and a width of 51 mm, this design is classified as a large-dimensioned rolling bearing. The rings and rolling elements are made from standard 100Cr6 bearing steel. Thanks to its open design, the bearing can be integrated directly into existing lubrication systems.
In which applications is the 6040 M deep groove ball bearing used?
This large bearing is primarily used where high radial forces are present in heavy-duty machinery and industrial gearboxes. The open design allows for a continuous supply of lubricating oil or grease from the surrounding assembly. The design is intended for enclosed housings, in which external housing seals retain the lubricant within the system and prevent the ingress of dirt particles.
What role does the brass cage play in the 6040 M deep groove ball bearing?
The suffix ‘M’ denotes a solid brass cage, which guides the rolling elements stably even under vibration or rapid changes in speed. Compared to sheet steel cages, brass is characterised by high strength and favourable emergency running properties. The bearing has standard radial clearance and complies with tolerance class P0 (ABEC 1). It is designed for operation within a temperature range of -20 to +150 degrees Celsius.
What are the dimensions of the 6040 M deep-groove ball bearing?
The bearing has an inside diameter of 200 mm, an outside diameter of 310 mm and a width of 51 mm. The rings and rolling elements are arranged in a single row without a flange or groove on the outer ring. These key dimensions determine the design of the shaft and housing bore in your application.
What does the suffix ‘M’ in the designation ‘6040 M’ for a deep-groove ball bearing mean?
The code letter M stands for a solid brass cage. This cage material offers mechanical stability and performs well under vibration or shock loads. Brass also has favourable friction properties under conditions of insufficient lubrication and helps to minimise wear on the rolling elements.
Why is the 6040 M deep-groove ball bearing designed as an open bearing?
As an open roller bearing, this design has no integrated seals or cover plates. It is designed for applications in which the housing provides the seal and an external lubrication system, such as an oil bath or recirculating lubrication, continuously supplies the component. This means there are no additional friction losses due to sealing.
What does the standard radial clearance for this ball bearing indicate?
Standard radial bearing clearance means that the bearing has a defined radial clearance when supplied. This clearance compensates for the operational shrinkage that occurs when the inner ring is pressed onto the shaft, as well as for moderate temperature differences between the inner and outer rings under typical operating conditions.
Within what temperature range can the 6040 M deep-groove ball bearing be operated?
This roller bearing is specified for a temperature range of -20 to +150 degrees Celsius. The thermal load capacity is determined by the 100Cr6 rolling bearing steel and the brass cage. When selecting the lubricant, care must be taken to ensure that the oil or grease used covers this temperature range.
What material are the rings and rolling elements made of?
Rings and balls are made from standard roller bearing steel 100Cr6, which offers high compressive strength and dimensional stability. The bearing is manufactured to the standard tolerance P0 (corresponding to ABEC 1). It is therefore suitable for general mechanical engineering applications where standard fits are used on shafts and in housings.
