Combiflex pneumatic brake DBK250 can well replace RE CX250 pneumatic brake. as usually, it is matched with a cooling fan on the top of brake, it is good for heat dissipation and prolong brake's service life greatly. this CX250 pneumatic caliper disc brake is widely applied for packing and printing machine.

2.Techincal parametersof DBK combiflex pneumatic caliper disc brake:
Name: DBK pneumatic caliper disc brake
Model: DBK10, DBK20, DBK-250.2, DBK-250.4, DBK-250.6, DBK-250, DBK-300, DBK-400, DBK-500
Bore diameter: 45-60mm
Weight: 1-15 kgs
Torque: 1-960N.M 
Air pressure: 0.1bar-6bar
Modular quantity: 1-6 pieces 

3.Performance featuresof DBK combiflex pneumatic caliper disc brake:
as usually the braking disk diameter is 250mm, so braking torque is determined by modular quantity and air pressure. When air pressure is 0.6Mpa, modular quantity more, its braking torque is larger, too. for example, when air pressure is 0.6Mpa, DBK250.1 braking torque is 160N.M; DBK250.2 braking torque is 320N.m. 
on the other hand, when braking plate diameter different, it produce braking force is different. For the DBK10, when braking plate diameter is 250mm, braking force is about 170N.M; if braking plate diameter is 350mm, its braking power is nearly 240N.m. so we can see that braking disk diameter, modular quantity and air pressure are three factors influence fan cooled caliper disc brake's braking force.
Available with high flow cooling fans and in configurations from 1 to 6 calipers.

4. Characters of DBK combiflex pneumatic caliper disc brake:
1.Customizable caliper configuration
2.Cast iron disc of 250 mm
3.Light alluminium structed
4.High performance pads compounds
5.Different pads models available: standard, anti-rotation, in Kevlar, with or without antivibration ring.
6.Pads RoHs compliant

5. Application of DBK combiflex pneumatic caliper disc brake:
Applicable to packing and printing machine, working machinery, construction machinery, steel rolling equipment, wire machine, stranding machine, coiling machine, cable equipment, gantry crane and crane, paper-making equipment, ship heavy-duty truck, trimming, discharging, positioning, tension control and other occasions.

in this case, DBK250 multiple pneumatic caliper disc brake is worked in paper making machine. It is 4 calipers with good heat dissipation. from it, we can see that DBK pneumatic brake is matched with mechanical chuck for paper roll loading and unloading. this couple is popular and easy operation.
