BK2-1 430 torque brake hydraulic motor M&S hydraulic disc brake


BK2 series brake is one kind of hydraulic wet disc brake. The brake force is caused by the spring, and hydraulic pressure releases the brake force.
Features as follows:

  • BK2 series adopts the special friction disc and high strength spring design: long
    life endurance, low noise, high braking reliability.
  • with 4 Drain port design , the brake can be used in different applications.
  • compact structure, easy mounting.
  • it can be used preferentially together with BMP, BMR, BMS series hydraulic
  • BK2 series hydraulic brake stays in braking condition since delivery out of the
    factory. During normal operation, there exists the braking force in the brake disc,

only if the pressure of hydraulic system, that the brake links , is lower than the pressure required by the release of brake, the spring force shall keep the brake in braking condition.

BK2 series hydraulic brake is widely used in heavy duty machinery, such as engineering machinery, cranes, off-highway machinery vehicles, construction machinery, material handling machinery, agricultural machinery, mining,sanitation machinery, timber ndustries. They are also used in winches and in hydrostatic drive systems for automatization engines.

In order to make the BK2 series brake work under the best situation, we recommend the
normal requirements as follows:

  • 1.Assembly: 1st of all , we have to mount the brake BK2 with hydraulic motor, and then fill the brake with lubrication oil through the drain port, and then mount with other parts.
  • 2.Fluid type:Mineral based-HM(GB/T763.2-87) (ISO6743/4) or HLP(DIN51524).
  • 3.Temperature range:normal -20℃-90℃the best optimal situation 20℃-60℃.
  • 4.Viscosity range : 20 ~ 75mm 2 /s; the best optimal situation 42 ~ 74mm 2 /s at 40 ℃ .
  • 5.Filtration:nominal filtration of 25 micron, ISO code 20/16.
  • 6.Maintenance: changed after the first 50~100h;then after every 500~1000h.
