Lapping Tools

Sacrificial gauge sets that repair taper damage and restore precise hub-to-shaft contact.

Lapping Tools

Product Overview

Lapping tools are a set of sacrificial gauges designed to repair light damage or restore the taper to a specific coupling hub or shaft end. Taper contact of 95% or greater is guaranteed after lapping.

When a hub or shaft end taper sustains light surface damage, re-machining is expensive and time-consuming. Riverhawk lapping tools provide a cost-effective field solution to restore taper contact without removing the shaft from service.

Key Features

  • Restores taper contact to 95% or greater
  • Repairs light surface damage without re-machining
  • Custom-fitted to specific hub and shaft geometry
  • Cost-effective alternative to shaft end re-machining
  • Field-serviceable in most turbomachinery applications

Taper repair after corrosion or handling damage
Pre-installation taper conditioning
Field restoration of coupling hub contact
Turbine and compressor shaft-end refurbishment
Post-inspection taper correction
