CTS Free Wheel Bearing
CTS company, established in January 1977, started his activity with the aim of marketing bearings and special drives and, in the same year, started the production of cylindrical roller free wheels.
The GF Series (sizes 8.20) and GV Series are bushed; the GF Series (sizes 25.60) have ball bearings. The GF Series are used as intermittent feed, non-return and over speed units mainly inside closed guards. To lubricate this range of freewheels, a pre-existing oil circulation may be sufficient, provided the type of oil used is one of those we recommend for cylindrical element contact units. The GV Series are used for return or intermittent feed applications and are located outside guards on drive shafts where the transmission torque is provided by the lever welded on the outer race. These types are supplied greased-for-life and with gasket.
US, USNU and UF Series freewheels used for intermittent feed, non-return or overspeed applications are generally placed inside closed guards (gears, end covers, etc.) in proximity to pre-existing bearings or additional bearings. The external and internal components must therefore be centred to each other; in the axial direction, they must not be under load or in tension. When pressing or extracting, simultaneously apply pressure both on the internal and external parts to avoid damage to the contact elements and springs. To lubricate this range of freewheels, a pre-existing oil circulation may be sufficient, provided the type of oil used is one of the recommended types for roller type
GM and GP are two types of cage, one with metric measures (GM) and the others with inches measures. The smaller dimensions and the high transmission torque offer some interesting technical and cost-saving solutions. When the application needs torques bigger it is possible to mount more cages side by side. The cage needs one or two bearings for centering, and the two rings (outer and inner) where the cage works must be a surface hardness of 60/62 HRC.
