Product Description

The Model D Roller Guide has been engineered to maximize economy while optimizing ride quality. Primarily designed as a counterweight partner to the Model B roller guide, it can also be used successfully on very light load, low-speed elevator cabs where the ride quality advantages of a spring-loaded guide are desired.

  • Neoprene Rubber Roller Wheels

    are specially compounded and rigorously tested to ensure a smooth, silent ride. Only genuine ELSCO neoprene wheels provide the damping characteristics essential to ride quality, and only genuine ELSCO wheels are engineered with high “memory” characteristics that prevent flat spots. ELSCO rollers are precision ground to within .002 inches (,051mm) “Total Indicator Reading” for perfect roundness and concentricity, then 100% inspected under stress to ensure a secure bond between tire and hub.
  • Durable Structural Components

    ELSCO castings are made from high-tensile-strength ductile iron and aluminum for an optimal combination of strength, durability, and light weight. High quality guide hardware ensures long life and ease of adjustment in the field. All components are inspected and assembled to exacting standards for a lifetime of reliable performance.
  • Precision Ball Bearings

    guarantee years of silent use. ELSCO specifies bearings intended for the high RPMs and demanding loads of electric motors – conditions far more rigorous than typically seen in elevator applications. This means that even after years of operation and tens of millions of cycles, only ELSCO roller wheels remain completely silent. Each bearing bore is machined to a tolerance of three ten-thousandths (.0003) of an inch (,0076mm), and two bearings are pressed into each wheel by a computer-driven press, ensuring perfect fit and alignment.
  • Fully Adjustable Stabilizing Springs

    allow the counterweight to float between the rails, eliminating the bumps and vibrations that adversely affect ride quality.
