Aero BB aerospace thin aluminum rail

<div class="fr-view sa_b_component_richtext_unique"><p><img title="10" src="https://www.jingyinkeji.com/uploadfile/ueditor/image/202405/1715241659edbb86.png" alt="10" class="fr-fic fr-dii"></p><p>&nbsp;</p><p>The Aero BB 130FL is a lightweight, full-range extender telescopic slide (47-54 kg per pair) designed primarily for defense and aerospace applications that require thinner specifications. In the case of 559mm, the carrying capacity of a pair of 54 kg, stroke 533mm, very suitable for electronics, aviation, Marine racks, military cabinets.</p><p>&nbsp;</p><p>The 130FL model has no locking or separating function, but a single slide can be used in combination with the 130FL-EN(lock book) to form a paired pair. We price the Aero BB rail series as a single rod to make interchangeability simple. The 130FL and 130FL-EN slides share the same catalog and step file. The only change is the locking mechanism detail on the FL-EN version, as shown below (LH for left and RH for right).</p><p>&nbsp;</p><p><img title="1010" src="https://www.jingyinkeji.com/uploadfile/ueditor/image/202405/17152416808b5f57.png" alt="1010" class="fr-fic fr-dii"></p><p>&nbsp;</p><p>Using high-quality parts, these slides feature full ball and sealed roller movement. The design is thin and compact, with a range of features including display locking, detachable tracks, or a combination of the two. The larger-size models in the same series have a unique sequential extension function to provide more stability and higher load.</p><p>&nbsp;</p><p>These slides are made of automotive grade 7N01 T5 aluminum to ensure strength. Standard anodized surface treatment meets MIL-A-8625 Type II standards. Steel balls are made of hardened steel and chrome plated. The cage separates the steel balls under vibration, ensuring smooth, quiet development (suitable for models with cages). Aero BB slides are up to 70% lighter than steel slides of similar size and load capacity.</p><p>&nbsp;</p><p>Prices are calculated on a single slide. The load load value is based on each pair of extended rails, each pair of two rails. Aero BB slides are manufactured to order, please allow 6 weeks of lead time unless you have signed an inventory plan with us.</p><p>&nbsp;</p></div>

Carbon steel rails are suitable for vehicle applications involving shock and shock. If there is a need for lightweight and corrosion resistance, we also have high-strength aluminum alloy slides to match (load up to 330kg).</p><p>&nbsp;</p><p>At the same time, the Navy-class 316L stainless steel slide can also be applied in the outdoor environment to ensure functional sustainability.</p><p>&nbsp;</p><h3>Ambulance vehicle</h3><p><br>Such vehicles need to store rescue equipment and allow medical personnel to quickly obtain equipment, the appropriate choice of telescopic slide can greatly improve the efficiency of rescue.</p><p>The safety of medical staff and operation is of Paramount importance. Choosing the right slide to build the interior drawer system can guarantee the above two elements.</p><p>&nbsp;</p><h3><span style="font-size: 24pt; color: rgb(35, 111, 161);">Rail industry</span></h3><p><br>From pull-out battery boxes installed on the bottom of trains, to train doors with high frequency switches, and seating systems that are growing year by year.<br>Sliding Systems are equipped with suitable products.</p><p>&nbsp;</p><h3>Battery box</h3><p><br>The slide used in the battery box needs to have extreme strength, and the slide assembly must be integrated with the battery box and pass the impact test.</p><p>At the same time, with the trend towards high-speed trains, battery box rails must be challenged to withstand huge dynamic loads to comply with the standard.</p><p>Battery boxes may also contain corrosive gases after long-term use, so careful selection of specifications and surface treatment is regarded as an important part.</p><p>Although the suspension system of the train is changing, the way to use the roller to extract the battery is still subject to vibration and shock and failure, which makes the shock slide the most suitable solution for the battery tank.</p><p>&nbsp;</p><h3>Door system</h3><p><br>The rails used in the door system must be able to withstand dynamic loads and meet impact test standards. At the same time, the rails must operate stably and require minimal maintenance at extremely high frequencies of use. In general, the doors of the subway are opened and closed at least 20 times in an hour, and the rails must be able to withstand this frequency until the end of the life of the transport system.</p><p>The ball and bead of the slide rail must be hardened to withstand such a high frequency of use, on the one hand, to avoid corrosion problems. Carbon steel slide also shows a higher durability, in the long term use of carbon steel slide is less likely to produce permanent deformation like cold rolled slide.</p><p>&nbsp;</p><h3>Seat system</h3><p><br>As railway technology improved, passengers began to be offered adjustable first/business class seats. Simplicity, durability, and low maintenance frequency are the key elements for the application of seat slides in rail vehicles.</p></div>
