RATING

The ratings of the units indicated in this catalogue represent the mechanical capacity of the gears and unit components for a service factor of 1.0 with respect to pitting and bending strength peak loading not exceeding the following conditions-:

• Not more than four peaks per eight hour working period.
• Time duration of each peak shall not exceed five seconds.
• Each peak shall not exceed 200 % of the catalogue rating.

Operating speed

The maximum operating speed of all the gear units specified in this catalogue is restricted by the factors such as pitch line velocity, lubrication, churning losses, bearing life & limiting speed of bearings. For operating speeds higher than those indicated, please seek our confirmation.
