Unlike conventional brakesoffered today, the SB brake is performance-matched to fit the full range small-frame SAE A mount motors availabletoday. With an overall diameter of less than 5.4” (137mm) the SB has a holding capacity in excess of 5,500 lb-in (620Nm) and is easily mated to a variety of global industry standard motor mounting and shaft options. In addition, the SBSeries can be used as a stand-alone brake solution without an input drive motor. This option further opens design flexibility to meet a wider variety of application needs.The SB series uses the same time-proven brake technology used in other White Hydraulic brakes and incorporates thelatest advances in multiple-wet-disc-brake technology. The design is a spring-applied / pressure release type that usesmechanical spring-force to apply the brake in the absence of release pressure. System pressure is applied to the brakerelease port to overcome the spring force to release the brake. In the absence of pressure, the springs activate the brakefor full system load-holding capability. In addition, all internal components including the bearings and brake discsare fully immersed in an oil bath to provide extended life and trouble-free operation. The brake is intended for use asa static load-holding brake with limited short-duration dynamic operation allowed. Actual customer testing and fullsystem testing is required to ensure the product meets performance requirements. All these features combine to makethe SB Series the leading small-frame brake in the world today.SPECIFICATIONSCode225315415520620Holding Torque2,000 lb-in(225 Nm)2,800 lb-in(315 Nm)3,700 lb-in(415 Nm)4,600 lb-in(520 Nm)5,500 lb-in(620 Nm)450 psi(31 bar)450 psi(31 bar)3,625 psi (250 bar)Max.

SBINSTALLATIONThe SB Brake is a wet multi-disc type static brake and is shipped factory filled with fluid. The fluid used is a standard SAE 20 hydraulic fluid. A hydraulic motor can be mounted to the SB Brake to provide a complete motor/brakepackage. A shipping cover protects and seals the input interface until it is ready for installation. The shipping cover isremoved by removing the two cap screws and following the motor installation procedure below. Mounting pilot surfaces need to be free of paint or other substances for proper assembly and leak-free performance. Standard SB brakesare sold unpainted with an easy to remove shipping cover. Stand-alone SB brakes come standard painted and factoryinstalled cover.The input interface must be sealed to keep the brake environmentally protected and bearings fully immersed in fluidfor proper lubrication and long life. Standard SAE 20 hydraulic oil is used in the brake cavity as well as typically usedin hydraulic systems.An internal seal is provided to seal long-pilot motors. When a short-pilot motor is used, an o-ring face seal is neededto properly seal the motor/brake interface. Two mounting bolts (M12 x 1.75 thread) and an o-ring seal with mountinginstructions are included in the brake installation kit 930999001 and shipped with each SB Brake.Short Pilot Motor Installation - .11 (2,8 mm) Ø3.25 (82,4)Stand-Alone InstallationFace SealInput Mounting CoverNote, the factory installed pilot seal may be left in place. However, this seal will notprovide proper sealing for motors with short pilot mounts, therefore, a face seal mustbe used.Long Pilot Motor Installation - .21 (5,3 mm) Ø3.25 (82,4)The SB can also be used as a stand-alone brakewithout an input drive motor. In these cases, themounting cover should remain in place and not beremoved. The cover seals the unit and keeps thebearings immersed in oil for lubrication and longlife.Internal SealFIG. A - End ViewTo remove cover, pierce andpry with a sharp awl.Note, the face seal contained in the mounting kit is not needed and may be discardedwhen mounting a long pilot motor.6

In response to that concern, White Hydraulics offers theBK10 Series brake. Based on technology proven in White Hydraulics integrated motor/brakes, this spring-applied,hydraulically released brake provides 10,000 lb-in of holding torque for static brake applications.Other features contribute to the superior operation and durability of the brake. All internal components, includingroller bearings, brake disks, springs and seals were chosen for maximum durability. To further extend the life of theunit and reduce noise, all internal components run in an oil bath. Two brake release ports are also provided to simplifyplumbing and bleeding of the brake release circuit during installation. All of these features combine to make the BK10Series brake the top choice for any static brake application requiring 10,000 lb-in of holding torque.SHAFT 31 1 ½” Tapered6.92Max.
