FAST'S® Gear Couplings Spacer Coupling Size 1 1/2 - 7

Standard Spacer Couplings

Full-flex spacer couplings are used for 4 bearing installations with extended shaft separations. Tabulated below are spacers for industry standard shaft separations, C_L.

Type EB exposed bolt spacers and Type SB shrouded bolt spacers for standard shaft separations are normally in stock. Other lengths are manufactured to order.

Spacer length, L, is calculated by subtracting the standard full-flex, close coupled gap, C, from the shaft separation,

Note: Spacer part number references the shaft separation, not the actual length of the spacer.

LEF Spacer Couplings

Limited End Float (LEF) spacer couplings are used for sleeve bearing motor applications with extended shaft separations. LEF spacers are supplied with steel LEF plates installed in each end.

Spacer length, L_LEF, is calculated by subtracting the LEF full-flex, close coupled gap, C_LEF, from the shaft separation, C_L. ^LEF

L = C - C

Note: Refer to Form 1900-62 for more information on limited end float applications.

Spacer Couplings Size 8-30

Couplings sizes 8 - 30 are also available as spacer couplings for extended shaft separations. These sizes are available in exposed bolt only.

Spacers for coupling sizes 4 - 30 are non-stock and are manufactured to order. LEF spacer couplings are also manufactured to order.

Coupling Greases

KOP-FLEX offers greases specifically designed for use in coupling applications. For proper lubrication and long service life, use KSG Standard Coupling Grease, or KHP High Performance Coupling Grease. See pages 204-206 for detailed specifications.
