The "A" Series pulleys are Adjustable Center Distance Drive
type pulleys with a 5-30 horsepower capacity range. The "MA" Series pulleys
are Fixed Center Distance Drive pulleys with a 5-125 horsepower capacity
range. Both series use a unique patented Asymmetric Belt which allows the
maintainance of belt alignment with single face movement pulleys on V-V
drives. The automatic pulleys contain Hi-Lo's torque sensing mechanism to
control belt tension with load requirement.  |

Becker: The premier name in state of the art variable speed drive technology
pioneered unconventional solutions in the development of asymmetrical variable
speed drives. The result was high power transfer and low belt wear which
no other comparable system can achieve. |

|
The DCV Series pulleys are Adjustable Center Distance Drive type pulleys
using Standard V Belts. The horsepower range is fractional to 7½ HP
at 1750 RPM. They have double pulley face movement to maintain belt alignment
on V-V drives and contain Hi-Lo's torque sensing mechanism to control belt
tension with load requirement.

 |
|
|
The DCW Series pulleys are Adjustable Center Distance Drive type pulleys
using Variable Speed Belts. The horsepower range is fractional to 30 HP
at 1750 RPM. They have double pulley face movement to maintain belt alignment
on V-V drives and contain Hi-Lo's torque sensing mechanism to control belt
tension with load requirement.

 |
|
|
The MCV and MCW Series pulleys are Fixed Center Distance Drive type pulleys.
The MCV pulleys use standard V-Belts and have horsepower ratings from fractional
to 5 HP. The MCW pulleys use Variable Speed Belts and have horsepower ratings
from 1-7½ HP. The automatic pulleys contain Hi-Lo's torque sensing
mechanism to control belt tension with load requirement.

|
|
The TBR Series of pulleys are Adjustable Center Distance Drive pulleys
using standard V-Belts. The horsepower range is fractional to 5 HP at 1750
RPM. They have single face movement to provide greater economy on longer
center distance V-V drives where absolute belt alignment is not critical.
Their through bore construction allows mounting from either end. Hi-Lo's
torque sensing mechanism controls belt tension with load requirement.

 |
|
|
The Hi-Ratio Series of pulleys are compound ratio type pulleys using
Standard V Belts. The horsepower range is fractional to 1 HP with speed
variation ratios up to 7:1.

Hi-Lo's VARI-Mod Case–A complete variable speed drive system which
can be combined with off-the-shelf components to build variable speed drives
of all types and arrangements. |
 |
|
|
Variable Speed Belt and Asymmetric Belt sheaves are made of close grained
cast iron, accurately machined and balanced for true running performance.
They use "QD" bushings to provide a wide range of standard bore sizes and
tight bore-shaft fits with ease-of-installation.
|
 |
|
|
Hi-Lo Belts are selected for optimum performance on variable speed pulley
drives. They are dimensionally stable, crush resistant, oil and head resistant
and static dissapating.
|
 |
|
|
Hi-Lo Motor Bases for Adjustable Center Distance Drives have been designed
to accomodate NEMA motor frame sizes 48 through 286T. They are of rigid
steel construction with lube-free bushings in the motor mount plates for
easy adjustment and greater wearability.
