FSPCR Type (F Type with a Spacer)

This drop-out spacer design allows for ease of maintenance without disturbing the equipment mountings. It has a lightweight construction to reduce the load on equipment bearings.

The FSPCR Type coupling consists of two standard F Type flex hubs, two standard F Type sleeves, one FSPCR Type spacer and two accessory kits. This coupling is available in either exposed bolts or shrouded bolt design.

Note: BSE = Distance "Between Shaft Ends"



Unit of Measure: Imperial Metric Both
