Bansbach FWM-2725FBD-S Shock Absorber
PRECAUTIONS FOR USE
- Do not use this product without carefully reading the attached owner’s manual.
- Ensure that an external stopper (Stopper nut OP-020FB) is also used.
- Do not turn the oil inlet screw located at the bottom of the main unit.
- Ensure that sufficient mounting strength is secured for this product. (As a guideline, it should be 2 to 3 times the maximum drag listed in the catalogue.)
- Do not use this product in a vacuum or a location where it may come in contact with oil.
- Ensure that an eccentric load is not applied to the soft absorber. (Allowable eccentric angle: within ±2.5°)
ADJUSTMENT METHOD
- To adjust, turn the adjustment knob located at the bottom of the main unit.
- Because the adjustment can be done in an analog manner, a value between two integers on the indicator can be set.
- Once the adjustment is complete, secure with a lock screw using a hex wrench.

OPTIONAL PARTS
Eccentric angle adaptor OP-010FB
- Screw the eccentric angle adaptor into the main unit until the cap for the eccentric angle and the piston rod form a tight connection. While maintaining this position, fasten the main unit’s nut until it is secured.
- Use the eccentric angle adaptor when the eccentric angle is 2.5° or larger.
- The main unit can also be used as a stopper.
- Use it with a capless soft absorber.
- The maximum operating eccentric angle with an eccentric angle adaptor is ±10°.
- The caps and the guides for inclined use are not unbundled
Note: Material of cap for eccentric angle: Metal
Stopper nut OP-020FB
- Adjust so that it stops 1 mm before the stroke end, and fasten with the main unit’s nut until secured.
Note: When attaching, make sure that the side without a bearing chamfer is the impact surface.
Standard nuts are sold separately as well – M27 Nut
Square flange OP- 040FB
- Once the attachment site is determined, use the main unit’s nut to securely fasten in place.
Liquid-proof cap FWM-2725FBD-C-060
- A drip proof cap is fitted on the unit on delivery.
- Liquid-proof caps are not sold separately.
- Ensure that the cap is facing upward.
If the cap is facing sideways or downward, it cannot provide an effective means for liquid proofing.
Holder with a switch OP-030FB
- Although a holder with a switch can be ordered on its own, we strongly recommend ordering one with the main unit. Please include the main unit’s model number when placing an order.
