    NORD modular worm gear products cover 5 industry standard center distances from 31 mm-75 mm (1.2 in-3.0 in) and range in torque capacity up to 3,779 lb-in. This product offering comes in a variety of standard, single worm, and compound worm ratios ranging from 5:1 to 10,000:1. The product family consists of the FLEXBLOC™ (SI Series) worm with universal gear housing and the MINICASE® (SMI Series) worm characterized by its smooth outer surface design and its separate footed and flanged gear housing. Exceptional modularity is guaranteed by offering a unified set of factory-stocked and easy-to-assemble accessory kits. This flexibility allows for a variety of input and output mounting options along with a large variety of output shaft options. The FLEXBLOC™ and MINICASE® worm gear products share many innovative design features.

    Advantages of the NORD Compact Coupled Unit

    • Easy to assemble and disassemble.

    • Eliminates fretting corrosion common to quill-mount inputs.

    • Maintains shaft alignment and provides vibration-free torque transfer.

    • Protects and isolates motor shaft and reducer shaft bearings.

    • Provides a stiff, high-strength, near-zero backlash connection.

    • Reduces the chance of bearing, shaft and key failures.

     

    UNICASE® One Piece Housing

    NORD heavy-duty, one-piece housings are precisely machined to exacting standards. Internal reinforcements further increase strength and rigidity. All bearings and seal seats are contained within the casting, eliminating splits or bolt-on carriers that can weaken the housing and allow oil leakage. Bores and mounting faces are machined in one step, producing extremely precise tolerances — thus ensuring accurate positioning of gear teeth, bearings and seals, and longer life for all components.

    • Increased torsional strength and rigidity.

    • Eliminates housing splits and bolt-on carriers.

    • Leak-free housing design.

    • Versatile mounting options and accessory kits.

     

    Modular Construction

    • Easy-to-configure input and output accessories.

    • Integral motor or motorized c-face units.

    • NEMA, IEC or solid shaft input options.

    • Footed, flanged or shaft-mount.

    • 10:1 helical pre-stage & compound assemblies.

    • Keyed hollow bore, solid shaft, and bushing-kit options.
