Product description:

• Types GFR, GFRN are roller type freewheels.
• These units are part of the Stieber modular system
• They are bearing supported, using two 160 series bearings, and require oil lubrication
• These units may be used in designs providing oil lubrication and sealing as on the example overleaf
• The bearings must not be axially stressed
• Typically, types GFR and GFRN are used with the F series covers that are designed to transmit torque, and provide oil lubrication and sealing
• Usually these covers are used in pairs according to combinations shown on the below technical data pages
• The outer race of the GFR model is plain to receive and centre any component bored to H7 tolerance
• Torque is transmitted by bolts through the cover plate in this case
• Types GFR, GFRN are identical except that type GFRN has a keyway on the outside diameter to transmit the torque
• Two paper seals are delivered with each unit to be placed between the outer race and cover plates
