FUN848 20 61 CC LM QCB Flanged Ungeared Imperial Slewing Ring

The F20i Imperial Series comprises a set of slewing rings of constant height approx 2.205 in (56 mm) with a flanged cross section on one or both rings, and with external diameters ranging from 19.9 in to 46.87 in.

Construction
Standard bearings incorporate plastic spacers, but ball spacers, steel or brass spacers, or even full complement or caged designs can be supplied for specific applications.

From 2015 all geared slewing rings will be manufactured in42CrMo4 steel for improved gear strength

Seals
A land riding nitrile rubber seal strip is standard. VITON seals can be supplied to order.

Gearing
Standard metric spur gears with 20 degree pressure angle and no addendum correction. Suitable pinions (as well as gearboxes and motors) can be specified and supplied. American standard gearing can be supplied if required. 

Lubrication
Bearings are assembled with a Lithium EP2 grease. Special greases can be supplied to order.

Applications
While a flange reduces the weight of the bearing, it also reduces it's torsional stiffness and these bearings are thus best suited to light or medium loaded applications where the load has no great eccentricity.
