NORD Gear Corporation has announced the addition of three single-stage gear units to its NORDBLOC.1 line. The new SK 871.1, SK 971.1 and SK 1071.1 represent the three largest single-stage NORDBLOC gear units manufactured by NORD and provide industry-leading thrust load capacity per case size.

The new products have a power range of 30 to 60 hp, a torque range of 3,540 to 8,850 lb-in. and a ratio range of 1.41 to 8.09:1. With durable UNICASE cast iron housing and optimized bearings, they can reliably handle large axial and radial forces and are perfectly suited for pumps, mixers, conveyors and industrial fans. 

Since NORD added single-stage units to the NORDBLOC.1 line in 2017, more than 65 OEMs in the United States have specified the single-stage units for a host of customer applications in food and beverage, oil and gas, and chemical industries. The newly expanded line will enable NORD to capture greater market share by providing a wider selection of configurations at a lower cost than competing gear manufacturers. 

“The primary reason for extending the single-stage product line is to provide customers in our target markets a full offering to cover all of their operational requirements,” said Tom Koren, director of engineering at NORD. “By providing single-stage compact gear units that meet the market requirements for speed and torque ratings, customers now can benefit from increased thermal performance, increased bearing ratings and a more compact designs at better price point than our competition."

With the rollout of the new SK 871.1, SK 971.1 and SK 1071.1, NORD is discontinuing its SK 41E and SK 51E gear units. To ease the transition for existing customers, the new single-stage units come with the choice of two standard output shaft sizes: one to match what the legacy customers are currently using and one to align with market standards. 

NORD offers eight single-stage helical gear unit sizes in the NORDBLOC line. Mounted by foot, flange or a combination of both – plus featuring solid shafts with metric or imperial extensions – the line provides customizable, flexible solutions for most high-speed drive applications. Gear units may be ordered with an integral NORD motor or with IEC or NEMA C-face motor adapters.
