Designed to extend bit life and maintain grease supply for the length of the run. Over twice the grease capacity of previous models ensures critical lubrication to the bearing. Only in Summit and Base products.
High Temperature and Lubricity Grease
Advanced synthetic grease allows for improved lubrication above 350°F and greater reliability in all applications. Only in Summit and Base products.
Patented Pressure Attenuator
This is a new enhancement for roller bearings. Naturally occurring cone pumps lead to pressure spikes thereby accelerating seal wear. This technology mitigates the pressure spikes allowing ample time for the canister compensator and seal to offset the spikes. Only in Summit and Base products.
Patented next generation shirttail protection using custom fitted tungsten carbide micro shields for enhanced wear characteristics. The micro shields conform to the shirttail contour providing seal and bearing protection. Only in Summit products.
Carbonate Grade Inserts
Carbonate formations worldwide pose ongoing challenges. Varel with the help of leading experts has developed high grade tungsten carbide inserts designed to mitigate heat checking and maximize toughness in carbonate formations. Only in Summit and Base products.
