SUN Triple roller series
SUN 3-Row Series
Triple row roller, ungeared
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.
The larger QCB sizes mimic those of other manufacturers but many are either modified for specific applications or designed in confidence.
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.
Should you need PDF drawings, load curves, CAD or STP files that are not yet uploaded to the site please e-mail
info@qcbslewingrings.com and we will send them to you quickly!

Interchange information
In our experience, these bearings are not easily interchangeable as application specific modifications such as bolt number, bolt hole style, grease point location and size can vary.
QCB is able to offer triple row roller bearings up to 11 000mm diameter, in single piece rings or segmented for easy transport, handling and assembly on site.
