Basic Structure and Principles: Vane Damper
Caution!
*Do not operate without sufficient mounting strength
Operating with insufficient mounting strength may damage the main machine and cause injuries. Ensure sufficient mounting strength of load torque x safety factor.
*Do not operate without an external stopper
Use within the damper&#;s range of operating angle. Do not use the damper itself as a stopper by setting the rotational limit position of the rotating shaft as the resting position of the rotating object. Using the damper itself as a stopper may damage the damper and consequently damage the main machine, and it may also result in injuries.
Set the external stopper to the operating angle before use.
*Do not use when the maximum operating torque is exceeded
Using this product beyond the maximum operating torque may cause an oil leak, reduced durability, and damage to the shaft. This may damage the damper and consequently damage the main machine, and it may also result in injuries. Do not exceed the maximum operating torque when using this product.
*Do not operate outside the operating temperature range
Using this product outside the operating temperature range may cause an oil leak and torque problems. Use this product within the operating temperature range.
*Usage enviornment
This product cannot be used in a vaccum or under high pressure, as this will cause damage to the main machine.
Do not use in an environment where chips, cutting oil, water, etc. can come in contact with the linear damper. This will result in a malfunction due to an oil leak caused by damage.
*Do not discard oil more than is necesssary
Discarding the oil contained in dampers more than is necessary will pollute the environment.
Dispose the oil according to laws concerning waste management and cleaning.
*Radial load to the shaft
Applying load to the rotating shaft (gear) in a radial direction may cause an oil leak, torque problems, and
damage to the shaft
(or to the gear if the gear is used).
*Thrust load to the shaft
Applying load to the rotating shaft (gear) in a thrust direction may cause an oil leak, torque problems, and damage to the main unit
(or to the gear, or cause the gear to become disengaged, if the gear is used).
When assembling, attach the damper's gear to the opposing arm (gear) as parallel as possible.
*Using the product above its maximum rotations
Using this product above its maximum rotations may cause an oil leak, torque problems, and damage to the rotating shaft.
Please refer to the catalogue for the product's maximum rotations.
(*If you are going to exceed the maximum rotations when using this product, please contact our sales department.)
*Using the product outside its operating temperature range
Using this product outside the operating temperature range may cause an oil leak and torque problems.
Please refer to the catalogue for the product's operating temperature range.
(*If you are going to use this product outside its operating temperature range, please contact our sales department.)
*Using the product above its maximum cycles Using this product above its maximum cycles may cause torque down and an oil leak.
Please refer to the catalogue for the product's maximum cycles.
(*If you are going to exceed the maximum rotations when using this product, please contact our sales department.)
Over-tightening of mounting screws
Over-tightening the mounting screws when installing a rotary damper may cause damage to the main unit.
Based on the types and sizes of the screws used, please apply an appropriate tightening torque to tighten the screws.
Bansbach Easylift of North America is not responsible for any secondary accidents caused by a rotary damper.
The user should implement preventative measures against such secondary accidents.
Execution with/without flange, bearing on one or both sides
Damping torque 0.89 in-lbs to 26.55 in-lbs
Damping direction right or left
Construction size Ø 0.98 in to 1.18 in
Rotational speed max. 30 rpm
Goto teao to know more.
Lifetime 30,000 cycles (1 cycle = 360° left-hand, 360° right-hand). Even after this time, the dampers still produce over approx. 80 % of their original damping moment. The service life may be significantly higher or lower, depending on the application.
Operating temperature range 14 °F to 140 °F
Material Outer body: Plastic
Mounting In any position
Information to the shaft Ø +0 / -0.001
Hardness > HRC55, surface smoothness RZ < 1µm
Mounting information
Turn the shaft in the opposite direction to the brake direction to avoid damaging the freewheel mount. No axial or radial forces may be induced via the shaft.
Safety information
Do not use rotary dampers as supports. Provide an external guide or support.
