SEG Triple roller series

SEG 3-Row Series



Triple row bearings exhibit the highest load capacity/diameter ratio. 

The QCB range of triple roller bearings is more extensive than most, starting with smaller units that have found use in a wide range of industrial applications where space is limited listed below.

The larger QCB sizes mimic those of other manufacturers but many are either modified for specific applications or designed in confidence.  Used in conjunction with multiple planetary geared motors tremendous amounts of power can be transferred.

Unless you are an OEM customer, these will only be made to order. 

As a result we have chosen to offer only the most basic dimension information on this site and invite you to contact us to discuss your specific requirements, or send the Enquiry/Design Data form through to us with your project details.

Interchange information

In our experience, these bearings are not easily interchangeable as application specific modifications such as bolt number, style, grease point location are variable.
