General Products Brief descriptions

Cam Clutches/Sprag clutches are precision devices which lock the inner and outer races through the wedging action of cams to transmit torque in one direction of rotation, and overrun in the opposite direction. These units are often referred to as freewheels, sprag, overrunning, backstop or one-way clutches, depending upon their application.

The freewheel is a basic part of mechanic drive. They can be widely used in packing machinery machine tool, crane and transport machinery, agriculture machinery, medical apparatus, light industry machinery, printing & dyeing machinery, food machinery, metallurgical and mining machinery, power equipment, machine drive parts of test stands, etc.

The products series including:

CKA; CKB（ B200 Series）,CKZ,CKD ;CSK, KK, ZZ, AS, AE, AS(NSS), ASNU(NFS), DC; FWC

Type ASNU(NFS)  is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outer diameter is the same as a series 63.. ball bearing.

Type AS（NSS） is a roller type freewheel non bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outside dimensions are the same as series 62.. ball bearings.

Type AE is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outside diameter is a standard ball bearing dimension.

Type DC is a sprag type freewheel cage without inner or outer races. It must be installed in a design providing races, bearing support for axial and radial loads, lubrication and sealing. The DC type version-N accepts all types of lubricants currently used in the power transmission equipment.

Type NFR is bearing supported roller type freewheel without any sealing. Lubrication and sealing must be provided by the installation. Standard lubrication is oil.

Size 8 to 20 units use steel on steel bearing support from the inner race. Above size 25, two 160.. Series ball bearings are used, giving a higher overrunning speed capacity. A typical arrangement is shown overleaf. The inner race is keyed to the shaft. The outer race has a positive n6 tolerance to give a press fit in housing to H7.Additional side notches provide for positive torque transmission. The housing must be strong enough to not expand after assembly.

Applications: the one way clutch bearing are widely used in automobile; motorcycle ;textile machinery; printing machinery ;home appliance; construction equipment; agricultural machinery; plastic machinery; speed reducer; electrical roller ;medical equipment ;fitness equipment; food machinery ect
