Company Profile
Washing Machines 6021 Deep groove ball bearings Gearboxes
Agricultural MachineryDescription:Deep groove radial ball bearings are radial deep groove ball
bearings.Characteristics:Support of axial and radial loads in both directionsSuitable for high speedsHigh precision deep groove ball bearings are always the best
solution, whenaxial loads from two directions have to be transmitted, and
existing space does not allow installation of matched spindle
bearings.best possible guidance of rotating parts is required and speed is
less important.Depending on the required load carrying capacity and the available
space, We offer deep groove ball bearings in size ranges 60.. and
62.. as per DIN 625.A large number of different cages, lubricants and closures allow a
design of bearing execution to fit most applications. The necessary
radial clearance can be specified by our application engineers if
desired.An additional increase in speed or service life can be realized
with our hybrid bearings. Some types are available as extra wide
special bearings with extended grease reservoir.Series: 6000 - 6016, open type, Z, 2Z, RS, 2RS;6200 - 6221, open type, Z, 2Z, RS, 2RS;6300 - 6321, open type, Z, 2Z, RS, 2RS;6403 - 6415, open type, 2Z, 2RS;16001 - 16024, open type, 2Z, 2RS;604 - 609, open type, 2Z, 2RS;624 - 629, open type, 2Z, 2RS;685 - 689, open type, 2Z, 2RS;694 - 699, open type, 2Z, 2RS;6800 - 6807, open type, 2Z, 2RS;6900 - 6907, open type, 2Z, 2RS;Applications:1.
