BD Adjustable Hydraulic Shock Absorbers Series

Overview

BD Adjustable Hydraulic Shock Absorbers Series is the standard industrial hydraulic shock absorbers. You only need rotate the adjustment knob changing the damping force to get the best energy absorption in different working conditions (weight, impact velocity, driving force etc.) and also provide best convenient model selection and application flexibility for customers because single model can meet wide ranges of operation conditions. End users also can adjust the knob to recover the best energy absorption if working condition changes.
BDC can supply broadest ranges of adjustable shock absorbers and mounting accessories for current buffer market.

 
How to use:

BD hydraulic shock absorbers use the advanced 0~12step ranges to rotate, get visible damping force curve and achieve perfect energy absorption.
“0”to get the minimum damping force, “12”is the maximum and the initial setting is “0”. You must adjust the knob changing the damping force to get the best energy absorption before using otherwise it can't protect your machines and even damage it per emergency deceleration, and also it will shorten the service life. Thus correct adjustment is most important, not only for confirming the best  damping step, but also to avoid damaging when incorrect adjustment occurred.

 
Adjustment Skills

Make sure the adjustment knob number is in “0”, installing the shock absorbers and start, then to rotate the knob to check the decelerating conditions through watching and listening. If the damping force is too small (no obvious decelerating phenomenon in entire stroke and you can hear "PENG" in the end), please adjust to next step. In order to avoid damaging the shock absorbers, please rotate the knob step by step(rotate from 0 to 4 is not allowed, should be 0 to 1,then to 2, to 3,to4,step by step). When the movement velocity is controlled, smoothly decelerated and only can hear "CHI", It indicated this step is the best, then to use the hex keys to lock the set screws. If shock absorbers suddenly decelerated when moved in beginning or central and hear a large impacting noise "PENG" ,please adjust the knob to smaller step to get smoothly impact deceleration, if the knob already in “0”, please use the smaller model; If suddenly decelerating happen in the end and make a big noise, and the knob is in 12 step, we recommend you to use the larger model.

 
Performance and Advantages

1. Damping adjustment design: adopt the advanced 0~12gear range to adjust, get visible damping force curve and achieve perfect energy absorption.
2. Orifices design: Giving up the single orifice design of European and American brands, adopting the newest multiple orifices design. In same working condition, new design generated the smallest damping force and get best energy absorption in a shortest stopping time. And also avoiding equipment damaged, reducing the noise, saving maintenance costs and shortening the cycle time to improve the productivity.
3. Cylinder and adjustment knob design: cylinder outer diameter range M10~M115; cylinder and adjustment knob can be perfectly assembled per installation and adjustment experiences;
Adjustable Small Bore Series :cylinder outer diameter M10~M36,full threaded cylinder and rear adjustment knob, can be easily installed and adjusted;
Adjustable Mid Bore Series:cylinder outer diameter M42~M64,full threaded cylinder and rear adjustment knob, can be easily installed and adjusted;
Adjustable Large Bore Series: cylinder outer diameter M85~M115, use convex cylinder + side adjustment knob design, it can be installed with convexity + lock ring or with flange. It's convenient to adjust to get best energy absorption.
4. Seal design: cylinder diameter OD ≥M20, all rod seals and rod wiper are used polyurethane materials, together with high intensity chrome plated piston rods, it can drastically improve the buffers service life and endure the harsh working conditions.
5. New bearing design to resist side load: use unique long front bearing + DU bushing to drastically resist the side load. This design can guarantee products service life and reduce the dependence on the installation accuracy.
6. New product to endure the max side load angle to 30°: Supply special models BD25-25SP and BD36-25SP to accommodate the rotated working station purpose .It can be smoothly worked without any special accessories.
7. Impact velocity range: 0.02~5m/s, out of this range, customized service can be offered. The highest velocity can be up to 20m/s.
8. Range of temperature: If use special seal material and hydraulic oil, the standard temperature range from -10℃~80℃ can be extended to -30℃~100℃.
9. Customized service: Based on the world class engineering team, BDC can provide special hydraulic damping technology solution and reliable verified testing reports.
