Precision Gearing 

GEAR SLUGS: Gear Slugs are produced 

from bar stock on automated band saws 

and stored in appropriately sized kan-bans. 

GEAR BLANKS: Gears are blanked on high 

precision CNC turning centers and inspected in 

accordance with the quality plan located at each 

work center. Particular emphasis is placed in 

maintaining parallel gear faces and minimizing 

run-out between the gear face and bore. 

GEAR HOBBING: Fully automated gear hobbing 

combined with carbide cutting tools produces gearing 

that meets a minimum of AGMA grade 9. Gears are 

analytically inspected on a computer controlled Hofler 

ZP250 for profile, lead, and spacing. Gears are also tested 

on a variable center distance gear tester and checked for 

tooth thickness by measurement over wires. This process is 

imperative to obtain smooth, quiet, chatter-free gear operation. 

HEAT TREATING: After hobbing, most Bison gears 

are induction hardened to increase strength and 

prolong gear life. Induction hardening is a process 

of hardening a ferrous alloy by heating it above the 

transformation range by means of electrical induction, 

and then cooling as required. With the appropriate 

induction equipment, this method selectively controls the 

heating pattern thereby producing a gear with properties not 

available with other heat treat processes.

Bison Pinions 

PINION BLANKS: Bison’s 

integral pinion blanks are 

produced on high precision 

CNC turning centers. This 

maintains concentricity 

between the pinion outer 

diameter and bearing 

journals. Since Bison 

pinions ride on needle or 

ball bearings, the bearing 

journals are typically ground 

to within .0002”- .0005”. 

Perfection 

DRIVEN 


PINION HOBBING: 

Similar to gear hobbing, 

carbide cutting tools 

on automated hobbing 

machines produce pinions 

that meet a minimum of 

AGMA grade 9. Since quiet 

operation is important, 

pinions are inspected on a 

computer controlled gear 

checker for profile, lead, 

and spacing. Pinions are also 

tested on a variable center 

distance gear tester and 

checked for tooth thickness 

by measurement over wires. 

HEAT TREATING: 

After hobbing, most Bison 

integral pinions undergo 

a hardening process 

called carbonitriding. 

Carbonitriding is a process 

where a ferrous alloy is 

case hardened by first 

being heated in a gaseous 

atmosphere. The alloy 

absorbs carbon and nitrogen 

simultaneously. The resulting 

carbonitrate layer offers a 

hardened, wear resistant 

surface and improves fatigue 

strength. Carbonitriding 

is also advantageous with 

regard to cost as it is well 

suited for mass production.

DUAL SCR CHASSIS 

The M2 drive provides the power of two drives in one! Now with one DC drive, you can 

control two different DC motors either independently or in a ratio mode. In independent 

mode, each side of the M2 can be controlled differently with different trimmer pot settings 

and different speeds. In speed ratio mode, one speed potentiometer sets the main speed 

while the other one determines the ratio of the speeds between the motors. In this mode, 

the drive replaces two single drives and possibly a separate master/follower card resulting 

in extreme cost and panel space savings!

ISOLATED SCR DC 

The PCM20000A Series of drives are a cost-effective solution for variable speed, process control applications 

from 1/20 to 2 Hp. The PCM21010A and PCM23001A are SCR drives that integrate isolation allowing them 

to accept external analog process control signals. Alternative solutions require users to wire a separate 

isolation card to the drive which adds cost and reduces available space.

The MM300 and MM500 Series of dual-voltage single quadrant SCR drives control 90 or 180 VDC SCR 

brush-type motors ranging from 1/20 Hp through 5 Hp. The MM311U, MM301U, and the MM501U drives 

have integrated isolation allowing them to precisely follow analog current or voltage signals from external 

devices or a potentiometer as a reference for motor speed control. This results in significant labor and 

material cost reduction compared to other systems employing a separate drive and isolation card.

The MM-PCM Series drive accepts non-isolated voltage (0-10VDC) or current (4-20mA) signals coming 

from an in-plant process, programmable logic controller, motion controller, etc. to control speed. A quick 

connect removable terminal block allows users to quickly detach the drive without disconnecting the 

wires from the terminal block. Also included are optically-isolated normally-closed stop and normallyopen

Minarik’s XL Series of filtered pulse-width-modulated (PWM) variable-speed DC drives 

provide exceptional performance. They output nearly pure DC power to brush-type motors 

ranging from 1/20 to 3 Hp. Drives accept 120 or 240 VAC input to output 0 to 130 or 240 

VDC, respectively; resulting in higher speeds from standard 90 or 180 VDC SCR duty motors. 

This innovative technology lets users operate many low voltage motors with only minor 

calibration adjustments.

Minarik’s DLC600 precisely controls your closed loop application speed. The DLC600’s dual 

voltage capability allows it to replace Minarik’s older DLC products. An encoder or proximity 

switch, hall effect sensor, or electromagnetic pickup can provide the necessary feedback. Any 

engineering units, from revolutions per minute, to widgets per day can be used to display and 

program the speed. The large 4-digit LED display allows you to easily see exactly what speed 

you are running. When it comes to low-cost closed loop control, the DLC600 is your solution.

DIGITAL CONTROLS 

Minarik’s VT8 Series is the choice when it comes to digital tachometers. 

The VT8 Series provides a simple and accurate readout for any object that has an optical 

encoder, magnetic pickup, or anything else that can generate a frequency related to what 

you wish to measure. 

There are four modes to choose from: tachometer mode for speed in any engineering unit, 

time in process for indicating the duration of an application, the inverse of speed (such as 

minutes per revolution), and basic totalizer for counting the frequency of the speed sensor.

Since most Bison gearboxes are oil 

lubricated for life, we understand 

the importance of precision ground 

seal areas. Bison shafts are hardened 

prior to grind in order to minimize 

wear on the seal journal. After heat 

treat, shafts are plunge ground 

on an automated grinding wheel, 

maintaining tight tolerances on 

grind diameter, lead, surface finish, 

and roundness. This superior seal 

grind coupled with spring loaded lip 

seals provides dependable, leak-free 

performance and the flexibility to 

mount all Bison gearmotors in any 

orientation.

• Output Shaft: Bison accommodates custom shaft 

materials, diameters, and other features to meet 

customer specifications. Carbon and stainless 

steels with features such as keyways, flats, thruholes, 

hex, threads, and slots are typical requests. 

• Shaft Seals: Depending on the ambient 

environment, we will provide the appropriate 

shaft seal for the application. Bison uses a wide 

array of seal materials including Nitrile, Viton®, 

and Polyacrylate materials. 

• Mounting: Bison can deliver the required 

mounting configuration when a custom flange, 

face mount pattern, or footplate is required. We 

can also provide metric mounts as needed. 

• Gear Case: Gear cases may be modified with a 

variety of mounting patterns, seal bores, foot 

brackets etc. For high volume OEM applications, 

custom designs are used to optimize form, fit, 

and function. 

• Lubrication: Synthetic and food grade lubricants 

are available in various temperature ranges. 

Let Bison application engineers help select the 

proper lubrication for the most demanding 

applications. 

• Bearings: Depending on the application 

requirements and the selected lubrication, Bison 

will choose the proper bearings to maximize life 

and minimize noise. 

• Motor: Permanent split capacitor, split-phase, 

shaded pole, capacitor start, capacitor run, threephase, 

inverter duty, PMDC, brushless DC, and 

steppers are a few of the input motor options 

available to OEM’s in a wide range of voltage 

options. 

• Termination: When special cordsets, lead 

lengths, connectors, terminals, junction 

boxes, or strain reliefs are required, Bison can 

accommodate.
