Overview

This document provides comprehensive technical specifications and dimensional data for the 700 Series single reduction gear reducers, covering both flanged and non-flanged models. It includes detailed information on product models, assembly types, mounting positions, shaft and keyway dimensions, mounting hole specifications, weights, accessory kits, and ordering references.

1. Product Models and Types

• F700 Series: Flanged Quill Type reducers.
• RF700 Series: Flanged Coupling Type reducers.
• Multiple assembly types available (Standard, G, H, J, R, B, BRB, C/D, E/F, X, HF700, HRF700).
• Mounting positions include horizontal base, vertical base, riser block, and input vertical up.
• Sizes range from 710 to 760; sizes 752 and 760 are exclusive to RF-Flanged Coupling Type.

2. Dimensional Specifications

• All dimensions are in inches.
• Key dimensions include center distance (C.D.), shaft diameters, lengths (A through W), output key sizes, and shaft bore dimensions.
• Mounting hole sizes, locations, and thread specifications (e.g., tapped holes) are detailed.
• Tables provide dimensions aligned with NEMA mounting standards (42CZ, 56C, 140TC, 180TC, 210TC, 250TC) and shaft keyway sizes.

3. Assembly and Mounting Types

• Assembly types define shaft projection and mounting surface relationships, including Standard, G, H, J, R, B, BRB (Base with Riser Block), C/D (Vertical Base), E/F (High/Low Base), X (Input Vertical Up), HF700 (Hollow Output Shaft), and HRF700 (Hollow Output Coupling).
• Mounting positions cover horizontal base, vertical base, riser block, and various flange configurations.
• Each assembly type has specific dimensional and mounting hole configurations.

4. Shaft and Keyway Details

• Input bore sizes and keyway dimensions conform to NEMA standards with tight tolerances (+.0015/-.0000).
• Output shafts are available in solid and hollow options, with detailed keyway sizes, lengths, and socket set screw locations.
• Key sizes vary by shaft size and NEMA standard (e.g., 1/8 x 1/16 for 42CZ, 1/4 x 1/8 for 180TC).

5. Mounting Hole and Fastener Information

• Mounting holes are typically tapped with specified thread sizes (e.g., 3/8-24 x 7/8 deep).
• Number and diameter of holes are specified per assembly type (e.g., 8 tapped holes, 4 holes of specific diameter).
• Socket set screws for hollow shafts are spaced at 120° intervals.

6. Weight and Accessory Kits

• Approximate weights are provided for each size and assembly type to assist in handling and installation planning.
• Accessory kits such as fan kits, base kits, and reaction rod kits are referenced with part numbers and page numbers for ordering.
• Some sizes have specific fan kit part numbers listed.

7. Ordering and Rating References

• Ordering information is available on page 14.
• Rating and performance data, including load capacities, are detailed on pages 15 and 20-29.
• Assembly and mounting position details are on page 16 (flanged) and page 17 (non-flanged).

Critical Information Summary

• Strict adherence to specified dimensions and tolerances is essential for proper fit and function.
• Selection of assembly type and mounting position directly impacts dimensional requirements and accessory compatibility.
• Sizes 752 and 760 are only available in RF-Flanged Coupling Type.
• Accessory kits must be ordered separately to complete assemblies.
• Shaft keyways and bore sizes conform to NEMA standards ensuring interchangeability.

Conclusion

This document serves as a detailed technical reference for engineers and purchasers specifying 700 Series single reduction gear reducers. It provides all necessary dimensional data, assembly configurations, shaft and keyway details, mounting hole specifications, weight information, accessory kit references, and ordering guidelines to ensure accurate selection, ordering, and installation in industrial applications.
