August 4, 2005 — New from White Hydraulics, Inc., Hopkinsville, Ky., is the new SB brake line, featuring a compact design (5.4-inch diameter x 4.53-inch length) and large, static load-holding capacity (620 Nm [5500 lb_f-in]). Designed for truck-mounted cranes, winches, boom lifts, marine winches, recycling equipment, drill-rigs, specialty skid-steer attachments, and other mobile applications, the SB brake can be used in standalone applications or in conjunction with any SAE-A motor, including the company's RS, RE and HB series.

 

Directly coupled to the output shaft, the SB brake uses spring-applied/pressure-release (SAPR), wet multiple-disc technology to provide fail-safe brake capability. All wear components are fully immersed in factory pre-filled fluid and are environmentally sealed to prevent contamination and corrosion while providing extended brake life and maintaining proper holding capacity. The SB is constructed with a cast iron housing, case-hardened steel shaft, and cylindrical bearing to provide long life.

 

The device can handle side loads up to 22,000 N (5000 lb_f) and has a minimum and maximum release pressure of 20bar (290 psi) and 250bar (3,625 psi), respectively. The release pressure is applied through a 7/16-20 SAE o-ring or 1/4 -19 BSPP port, and is independent of motor pressure, allowing it to be applied with the motor in series circuits and not be affected by motor backpressure.
