Oil Types
-40˚ Ambient Oils
Special ISO VG 150 and 220 viscosity synthetic oils are recommended for gear units working under -25 ˚C ambient temperature conditions.
Biodegradable
They are not harmful to the environment as low as possible with their high soluble properties. They are compatible to CEC-L-33-A-93 test standard which defines maximum 21 days of biological solubility.
Food Grade Oils
Recommended oils for gear units working in food production lines, where oil can be mix in products accidently. They are suitable for NSF H1 category.
Synthetic Oils
They are recommended for higher and lower ambient temperatures compared to mineral oils, because their viscosity change is low with the temperature. 25000 hours change interval is recommended between -25C / 40C ambient temperatures.
Mineral Oils
ISO VG 220, 320 and 460 viscosity oils are used in our units. They are usually recommended for temperatures higher then zero and up to 40 degrees. The mineral lubricant should be changed after every 10000 hours.
Sealing Options
Taconite Sealing Application
Labyrinth sealing application suitable for very dusty and corrosive working enviroments. They are usually mounted with extra graser system.
PTFE Sealing
Sealings made from polytetrafluoroethylene material which has low friction coefficient and are very resistant to chemical enviroments. They can work between -80C and +200C temperatures. They are useful for chemical working conditions.
Labyrinth Seal Application
Different protective techniques applied on sealings working on very dusty enviroments.
Cassette Sealing (FKM, NBR)
They are specially designed sealings made from FKM and NBR materials. They are mostly used corrosive enviroments to prevent these corrosive materials to enter inside gear unit. We use these sealings on low speed shafts.
Viton Sealing (FKM)
These sealings are produced from fluorocarbon material and used on high speed shafts. They are suitable for -25 °C to the +160 °C working temperatures. We use viton sealing on our input shafts.
Nitrile Sealing (NBR)
Nitrile sealings are suitable for low speed shafts. Their working temperatures are between -40 °C +100 °C. We are using nitrile sealings with dust lip on output shafts of our gear units.
Lubrication Options
Nilos Ring Application
Upper bearings thats can not lubricated by splash are made closed bearing by sheet metals named nilos ring. Closed bearings are lubricated by greasers.
Oil Expansion Tank
While gear unit is working on some mounting positions oil level needs to be very high to lubricate higher working parts and this can cause oil leakage when working speed is high. To prevent leakage an expansion tank is mounted on gear unit, creating extra space for increasing volume of inside oil while working.
Forced Lubrication
Especially for industrial gearboxes upper bearings can not get oil with bath lubrication while working on some mounting positions. To lubricate these bearings oil from lower levels pump up directly to the bearing. Efficiency is much higher with the help of lower churning loses.
Oil Bath Lubrication
Lubrication system without any additional equipment. All of interior parts(gears, bearings and seals) gets lubricated by splash or directly.
Cooling Options
Cooling with Oil/Water Heat Exchanger
An oil/water heat exchanger with pump is mounted on gear unit. Cooling is done through heat exchanger with cold water. Additional equipment is available if needed like pressure switch, flow switch and manometer. It is suitable for every mounting position.
Cooling with Oil/Air Heat Exchanger
Cooling system consists oil/air heat exchanger, motor pump and a filter. Gear unit and cooling system mounts on a steel base frame. It is recommended for ambient temperatures below 40 C and not very dusty environments. Another advantage is that it does not need cooling water.
Cooling Coil
Cooling is done with cold water passing through copper pipes inside gear units oil. It needs cold water maximum 30 °C temperature. It is suitable for H and B series gear units for M1 mounting position.
Fan Cooling
A cooling fan is mounted on input shaft to create air flow through gear unit. It is the most practical cooling option without any need for cooling water. It is suitable for working conditions below 40 degrees and it is not suitable for dusty enviroments.
Brake Options
Eldro Brake Application
Eldro brakes are usually preferred for high tonnage crane applications. They are mounted between gear unit and AC motor. We use Eldro brakes on H series gear units if our customer wants.
Centrifugal Brake
Centrifugal brakes are mounted between AC motor and gear unit for extra safety purposes with main brake. It stops the AC motor while running with inertia of main load that occurs if main brake has any failure.
Electromagnetic Brakes on Housing
Electromagnetic brakes are mounted on opposite side of input shaft in H series gear units. Usually preferred for crane applications because they enable easy maintenance of AC motor.
Backstop
Backstop on Housing
Backstop application that are mounted opposite side of input shafts on H series gear units and on secondary stage shafts on K and B series gear units.
B5/B14 Input Flange with Backstop
Backstop can be supplied inside new B5/B14 input flange which includes two bearings and elastic coupling.
Backstop on AC Motor Shaft
Backstop applications thats are mounted on back side cover of AC Motor. They are usually preferred because they are economic and compact.
Torque Limiter
Torque Limiter
Torque limiters are mounted between AC motor and gear unit with B5 flange. They limit the passing torque to the set value between motor and gearbox. When the limit torque reached proximity sensor sends signal to stop motor to prevent damage to limiter.
Gear Units with Base Frame
HT Series
HT series gear unit, coupling and AC motor with foot are all mounted on steel base frame. Couplings can be geared, rubfleks or hydraulic.
BT Series with Torque Arm

Couplings
Hydraulic Coupling
They are mounted between AC motor and gear unit. It is preferred for applications with high inertia to soft start the motor and lengthen the gearbox life.
Rubfleks Coupling
It can be used on input or output shafts of gear units. It compensates misalignment of shaft connection. Material of coupling housing is GS52 steel.
Electric Motor Options
