Types AA,AE,ANF and ANR - Roller Ramp Clutches

Please click image to order a catalogue.

These freewheels are high torque roller ramp clutches for applications within an encased lubrication system. Torque is transmitted by keyway in bore and 2 keyseats on end faces of outer race (except AA series). Type AA has drilled outer race to bolt to gears, or to machine housing if used as backstop when cover F4 from AGF series can be used to provide fully sealed unit. Types AA and AEF incorporate axial clearance "S" to avoid need for precise axial positioning of inner and outer races. This can also accommodate shaft temperature expansion. Type ANR incorporates its own bearings to centre inner and outer races. Size ANR 8-20 have steel on steel plain bearing, whilst larger units use two series 160 ball-bearings.
Types AGF and AGFN Roller Ramp Clutches
Combined Roller Ramp Clutch with Ball Bearings and outer race tapped to accept End Flanges
AGF and AGFN freewheels contain their own bearings, to centre inner and outer races. The outer race is tapped to enable fitting of a range of standard end flanges, but can equally be adapted to fit gears, or other driven equipment to suit special applications. Combination with standard end flanges or flexible couplings provides complete unit, with its own lubrication, enabling easy fitting to drive equipment.
Type AGFN incorporates a keyway in the outer race for torque transmission, enabling simple connection of gears, sprockets and pulleys. Clutches, with the outer races having through drilled holes instead of tapped holes, are available to order (types ALF & ALFN). These clutches use V ring face contact seals for reduced overrun drag torque, and also permits higher overrun speeds on outer race, and so are particularly suited to high speed indexing and continuous overrun applications.
Types AGF and AGFN Clutches assembled with End Flanges

Combination of AGF Series roller ramp clutches with a selection of end flanges provides a versatile range of clutches complete with own bearing support and integral lubrication system. Flanges can be combined as required to suit most applications, the following combinations being most common.

AGF-Fl-F2 is most popular combination, enabling easy mounting of pulley, sprocket or gear on outer race. F2 flange enables re-lubrication. AGF-F2-F7 is designed to enable connection of flexible couplings and universal joints. Can also be used to locate on m/c frame as backstop. In this application F4 cover could be used instead of F2 plate. AGFN-F5-F6 enables simple fitting of gears, sprockets, pulleys, etc. with positive drive through key on outer race.
