Drive cone –The drive cone is made from ductile iron and is precision ground for long service life. It contains inner air chambers for efficient heat dissipation. It is independently supported by a shielded bearing mounted into the motor adapter/slide – not just by the motor bearing.
Traction ring – ComTrac's self-lubrication traction ring is made from a proprietary material that provides exceptional resistance to wear and high temperatures. When replacement is necessary, only the ring and not the entire friction ring mounting flange is replaced.
Speed adjustment – ComTrac's rack and pinion speed adjustment system features stainless steel components to resist corrosion and is dust resistant by design. The stainless steel pinion shaft and ductile iron rack are designed to provide assured speed adjustments in the wettest, dirtiest environments.
Handwheel control – Handwheel control with a position indicator is standard on every ComTrac drive. Remote speed controls and overspeed protection is also available.
All ComTrac drives are shipped with the handwheel positioned on the left as viewed from the output shaft end of the drive. The handwheel can be quickly and easily moved to the right side by using the tools and instructions included with the drive.
Mounting position – ComTrac non-gear drives can be mounted in virtually any position. Units for vertical mounting (output shaft up or down) or washdown duty must be specified when ordered.
NEMA C-face input – All ComTrac drives feature a NEMA Cface input – that means standard off-the-shelf motors, available locally. ComTrac's patented corrosion resistant collet clamp ring makes motor shaft attachment fast and simple. The proper hex wrenches are included with each unit in the motor access cover. When the motor must be replaced, it can be done easily and quickly without disassembly of the entire drive.
In addition, the 0F unit is standard with a NEMA C-face output flange. It enables you to add adjustable speed capability to new or existing applications.
Torque compensator – The torque compensator assembly features high-capacity cylindrical roller bearings – not needle bearings – for long life and quiet operation. The design allows speed changes during operation or while the drive is at rest. The load compensating cams precisely match the pressure between the drive cone and the traction ring in proportion to the load torque.
Cast iron housing – High tensile strength cast iron housing for long service life in demanding applications. Stainless steel nameplate.
Two year warranty – Every ComTrac unit is backed by a two year warranty.
Delivery – ComTrac units are shipped in 3 days or less.
