Maintenance free, using high-performance grease assuring outstanding durability and reliability |
|
 |
|
GX-series One-Way Clutches are supplied “ready-to-use,” and require no
maintenance such as greasing up, cleaning or grease change, offering significant
economies of time and labor. |
|
 |
|
GX series use the high-performance grease developed by NSK. It assures outstanding reliability over an ambient operating temperature range of -20 to +80ºC. |
|
 |
|
Wide cams with a larger radius of curvature than conventional models achieve
high torque capacity under high loads for improved safety. A unique cam
shape allows the GX series to withstand even shock loads without slipping |
|
 |
|
NSK’s expertise in ball bearing manufacturing technology ensures high dimensional precision of the cams, and inner and outer races, offering long service life. The high-performance grease used to lubricate the GX series also helps minimize the wear on each part and prolong its life. |
|
 |
|
GX-series One-Way Clutches are supplied as integral systems with all components built in. They are ready to be used “as it is”. |

|
Applications |
|
 As an overrun control device
 |
The difference in the rpm between inner and outer races causes the clutch to engage or disengage. The clutch can be used in this way as a release mechanism for excess torque in fans or gear systems in industrial machinery.
Example applications: Automated machinery, fans, pumps
The operation of the motor causes the clutch to engage so that the pinch rollers rotate, feeding the material forwards. If the rollers feed the material too fast, too slowly or stop feeding, the clutch disengages, preventing any damage to the material due to slipping.
|
|
|
|
As an indexing control device
 |
The clutch can be used as an intermittent drive mechanism, converting the continuous rotation or reciprocating motion of an input axis into intermittent motion.
Example applications: Printing presses, wrapping machinery, metal pressing machinery, turntables for machine tools
The clutch converts the continuous rotation or reciprocating motion of
the input axis into intermittent motion.
|
|
As a backstop device
 |
The clutch can be used as a backstop device by fixing the outer race and allowing only the inner race to rotate. If the inner race comes under a backward force, the cams engage, stopping any backward motion.
Example applications: Belt conveyors, bucket elevators
While the motor is running, the inner race of the clutch free-wheels. If the conveyor slips or the motor stops, the clutch engages and prevents the conveyor from moving backwards.
