W.C. Branham Inc. updates the H2-90D hydraulic wind turbine caliper disc brake with quick change pad feature. There is no longer a need to dismount the brake to replace the friction material which will save considerable time and expense when servicing the brake. The H2-90D is a double live side caliper disc brake made from cast ductile iron. It fits on brake discs from 20 inches to an unlimited diameter. Standard sizes are available with disc widths of 1/2, 5/8, 3/4, 1, 1-1/8, and 1-1/4 inches. Spacers for metric disc widths are available upon request. Choose optional piston spring retractors for enhanced life of friction lining. The H2-90D brake can be ordered complete or as an OEM version without spacer and bolt hardware. Rated for 2500 psi hydraulic pressure, the H2-90D produces a clamping force of 103,200 lbs at 2000 psi and a tangential force of 46,440 lbs. Interchangeable with Svendborg BSAB 90, Antec HE-2-90 or Sibre ABT 90G.
