Babbitt bearings are important to all heavy industrial machinery because they are used for high speed, rotating equipment, such as compressors, turbines, electric motors, large power generators (like those in power plants). Babbitt bearings are sleeve bearings made of certain types of alloys, which are melted down and cast to produce the bearing surface. The Babbitt bearing was invented in 1839 by an American named Issac Babbitt. The first types of Babbitt plain bearings were composed of tin, antimony and copper. This composition is still pretty similar today. Babbitt is soft but strong enough to resist the bearing load. Babbitt bearings are made in a few simple steps: 1. Bearing shells are restored by melting out the original Babbitt material. The grit is blasted from the shells. The bearing shells are inspected and immersed in a 100% molten tin bath to assure a good bond for the new Babbitt. 2. The prepared shell is placed into the casting machine prior to spinning. 3. Special machines are used to spin-cast bearings. These machines employ bottom draw pouring furnaces and inert gas pressurization of the cavity being cast. This guarantees an oxidation free environment for molten metal. 4. When the centrifugal casting process is used, all virgin Babbitt is securely suspended on the walls of the shell, which yields a completely void-free casting and superior grain structure for extended wear and reliability. 5. After the bearings are cast, they are proof-machined and ultrasonically inspected for bond integrity. Can these bearings be refurbished ? Yes we can refurbish these bearings for air compressors such as Ingersoll Rand Centac, Cameron and Atlas Copco ZH compressors.

We recently designed a 3D printed rear oil seal for Centrifugal compressors that allows rapid exchange of the oil seal ensuring a time saving and ultimately a cost saving. The seal was designed with Solid works software and the plan is to 'factory' test the oil seal in August 2023. Should the test be successful we hope to market the seal not only to the manufacturer but also end users and distributors of this Centrifugal air compressor The original oil seal design doesn't allow a rapid exchange of the oil seal when it starts leaking. This is due to the original oil seal having a solid construction and requires the motor and drive coupling removed before the solid seal can be replaced. Our seal will cut the replacement time down to a couple of hours. For more information contact us at www.ztechnique.com

Our capabilities have expanded this year 2023 to include re-bearing overhauls of all sizes of Atlas Copco 'G' series air ends. "Providing this service for our customers has been both beneficial for both parties since we began investing in equipment and spare G air ends for this venture." MCW A recent order from the USA for 2 x GA250 air ends fully overhauled is underway 12-05-23 as seen here. The saving for this customer has been quite significant even though we are in the UK. Our core stock has improved dramatically by investing in used G series equipment thus ensuring a quick turnaround for customers. We hope to continue improving our re-bearing air end lead times and service exchange capabilities into 2024.

Up to 30% Energy Savings Reducing the amount of energy you use is one of the fastest and most effective ways to save your business money. Air compressors can account for between 15 - 25% of the total energy use within a business. By reducing energy costs you will be making a positive contribution towards climate change as well as your profit margin. In addition to the immediate cost saving benefits of an approved VSD conversion there are substantial incentives available through Government supported schemes to reduce energy consumption and your carbon footprint. What's Involved The conversion of your fixed speed air compressor is quite straight forward. First we modify your drive motor with a fully insulated bearing installed to the non drive end of the motor. We then attach the VSD drive , typically an ABB ACS VSD unit to your compressor motor using fully insulated cables and disconnect your Star Delta starter completely. ​ The next step is installing an auxiliary fan cooling to the rear of your drive motor and lastly installing an auxiliary oil pump for additional lubrication at low speed use. ​ Your compressor control system is then connected to the ABB VSD drives control panel. Starting the compressor is the same you simply use your existing controllers start / stop buttons and let the compressors auto load functions take care of the rest. Can you convert air dryer's Yes you can convert your air dryer such as an Atlas Copco MD regen dryer for example. ​ The conversion would consist of two adaptations to have consistent dewpoint. The first recommended conversion would be to install a 'low load' kit that ensures heat is always provided to your regen air above 125'c to ensure drum drying is always taking place. The second conversion would be to replace the drum dryer motor with a VSD type motor and small VSD drive unit synchronised to the main ABB VSD ACS drive unit. This dual conversion ensures you have a reliable dewpoint and energy efficient control of your compressed air equipment. Questions that normally are asked about VSD Conversions Oil Free & Oil Lubricated air compressors can be converted to VSD drive. The conversion is very similar for both types of air compressor. Quantify my savings We carry out both pre and post compressed air energy audits of your compressed air system and prove to you how energy savings are being achieved. Warranty ABB VSD drives are covered by the manufacturers warranty for 18 months from the date of supply. Our conversions are covered for 12 months warranty from the date of commissioning.
