Prime Features :
Service Limits, Application Parameter :
High thermal conductivity for cool running.
Very good start-up and emergency running characteristics.
Less gland adjustment, easy break-in, & even compression
PREVENT Galvanic corrosion of the spindle/shaft
Excellent low co-efficient of friction and minimal Shaft wear.
Very Resilient and resistance to thermal shock & high thermal conductivity
Significant serviceability of packing.
Non-abrasive; hence rules out shaft scoring
Provides better sealing in rough, wear and tear conditions.
Special grade Sigma 171C for Nuclear Application
Available in all Popular Square Section from 3 mm to 38 mm.
