Unwind applications need brakes with consistent torque and good heat dissipation. Nexen tension control brakes have finned and/or drilled rotors engineered to remove heat effectively. Four unique designs and fourteen model sizes provide excellent performance and long life. Each brake series has multiple friction facing choices to suit specific tension applications.
SA/TA Advanced Tension Brakes
High thermal output and torque ratings of the advanced series make these units ideal for demanding tension operations. Full range of sizes to meet all unique specification requirements. Advanced Series offers both straight bore hubs or tapered bores for QD bushing mounting. Both models are available with Standard, Low Coefficient (Loco) or Ultra Loco friction facings to meet all torque requirements.
W1000 Tension Control Brakes
The W1000 water cooled brake is ideal for high torque, low RPM, web tensioning or continuous slip applications where air cooled products are not able to dissipate the heat or must be greatly over sized to do so. It provides 8 thermal horsepower of continuous heat dissipation regardless of the RPM.
STB Tension Brakes
STB 600 and 940 Brakes allow superior torque control for your web. Three different sized piston sets can be actuated singly or in any combination for a large number of torque-to-air pressure ranges. The ventilated rotor creates an airflow path that draws cooler ambient air into the center of the rotor. The flow path directs air past the interface and dissipates heat radially away from the unit.
BTBA Tension Brakes
BTBA Tension Brakes provide high thermal performance by integrating a cooling fan and guard in a compact package. They offer up to four unique torque ranges to meet a wide range of tension control needs.
XTB Tension Control Brakes
XTB, multi-caliper, tension control brakes maximize heat dissipation by deflecting it away from rotor the brake components. Fins on the rotor, hub back and calipers to throw dissipated heat into space, not into the brake. The fin design also draws cooler air around and over the brake. Six models, thermal capacity up to 60 horsepower with a dual rotor.
XTBA Advanced Tension Brakes
XTBA is a multi-caliper with heavy-duty, cross-drilled rotors, air-cooled tension control brakes. Models with 10, 12, 14 and 18-inch rotors provide up to 32 horsepower thermal capacity.
