Deep Groove Ball Bearings FAG 6338 -M-C3
The FAG 6338 -M-C3 single-row deep-groove ball bearing, measuring 190 x 400 x 78 mm, with a brass cage and C3 clearance, offers high load-carrying capacity for large industrial drives.
The 6338 -M-C3 deep groove ball bearing from FAG Rolling Bearings is a single-row radial ball bearing for heavier industrial applications, with a bore of 190 mm, an outer diameter of 400 mm and a width of 78 mm. Manufactured from standard rolling-bearing steel 100Cr6, the rings and rolling elements offer dimensional stability. As an open design, this large bearing allows for flexible integration into existing lubrication systems. This rolling bearing is equally suitable for operational maintenance engineers dealing with machine breakdowns and for industrial buyers seeking standardised components with standard tolerance class P0/PN or ABEC 1.
What is the 6338 -M-C3 deep groove ball bearing suitable for?
This large roller bearing primarily accommodates high radial loads as well as axial forces in both directions. Typical applications include heavy-duty industrial drives and power units subject to continuous stress. Thanks to its solid brass cage, the component performs reliably even under severe vibrations or fluctuating speeds. Maintenance engineers appreciate its dimensional accuracy during major repairs, whilst distributors and purchasers benefit from its compliance with international tolerance standards.
What does the designation -M-C3 mean in terms of operation?
The suffixes define specific design features: the abbreviation ‘M’ refers to the guided brass cage, which is mechanically less sensitive to vibrations than standard sheet metal cages. The designation ‘C3’ indicates a slightly increased radial bearing clearance. This increased radial clearance is beneficial at operating temperatures between –30 and +200 degrees, as thermal expansion of the shaft and housing can reduce the operating clearance. When fitting the open bearing, ensure a clean installation environment and an adequate supply of lubricant.
What are the dimensions of the 6338 -M-C3 deep-groove ball bearing?
With an internal diameter of 190 mm, an external diameter of 400 mm and a width of 78 mm, the bearing has standardised key dimensions. This allows the component to be fitted precisely into housing bores and onto cylindrical shafts.
What distinguishes C3 bearing air from standard bearing air?
Compared with standard bearings, the C3 designation indicates increased radial clearance. This additional clearance compensates for thermal expansion caused by continuous operation at high temperatures or by temperature differences between the inner and outer rings, and prevents the rolling elements from becoming stressed.
Why is a brass cage used in this bearing?
The brass cage, marked with the letter M, offers high mechanical strength and good run-on properties. It reliably guides the rolling elements along the raceway even under acceleration, speed fluctuations and shock loads. This makes the large bearing particularly suitable for demanding applications in heavy industry.
What temperature range is the 6338 -M-C3 deep-groove ball bearing suitable for?
The permissible operating temperature range is from -30 to +200 degrees. The dimensional stability of the 100Cr6 rolling bearing steel used and the heat-resistant brass cage allow the bearing to be used both at low ambient temperatures and under high heat exposure, provided the lubricant is suitable for the respective temperature.
What are the characteristics of the open design without a seal?
Without integrated sealing washers, the open design allows for flexible lubrication via the housing system using grease or oil. Furthermore, there are no friction losses caused by sealing lips coming into contact with the housing. To prevent contamination and loss of lubricant, external housing seals must be incorporated into the design.
Which tolerance class does the roller bearing correspond to?
The component is manufactured to standard tolerance class P0/PN or ABEC 1. This classification defines the permissible dimensional and runout tolerances for cylindrical shaft seats and housing bores in general mechanical engineering. This provides industrial buyers and maintenance engineers with a component featuring standardised dimensional accuracy for direct installation.
