Pinions for high torque applications or large slew rings are generally designed and made to order. Heavy duty slewing rings usually incorporate an addendum correction factor on the gear tooth and the pinion(s) must be suitably corrected and truncated to ensure an efficient mesh in operation.
NBC uses some of the best software available to ensure we offer you the best solution
An offshoot of our usual slewing ring sales, we offer special ring gears to special order.
Gearboxes and motors
Planetary gearboxes are ideally suited to slewing ring applications as they exhibit high torque, low speed operation in a compact unit.
In conjunction with ROSSI UK, NBC is pleased to offer a range of planetary and other gearboxes covering a wide range of output torques and speeds suitable for most industrial applications.
Output shafts (hollow or fluted) can be tailored to the specific requirements of the job; and we can offer a choice of either single or 3-phase electric motors or even hydraulic power.
If you need hydraulic power, we have teamed up with the UK manufacturer ADAN Hydraulics.
