Aerospace Bearings
The commercial, military, and private aerospace industry operates with the maxim that failure is not an option. Aerospace and aircraft equipment function under extreme and varied environmental and performance conditions and are subject to strict manufacturing and OEM guidelines. Equipment, often operated remotely, is inaccessible for repair and maintenance. Aerospace bearings demand precision. They must be:
- high quality
- reliable
- durable
- flawless
- contain domestic components
Aerospace bearings can be found in:
- manned and unmanned aerospace equipment
- fuel control systems
- aircraft instrumentation
- communication satellites
- worldwide telephone services
- data transmittal services
- solar arrays
- guidance and navigation systems
- rocket booster components
Companies utilize stringent supplier quality requirements to manufacture corrosion resistant, precision, miniature, metric, and instrument aerospace bearings from:
- 440C stainless steel
- Silicon Nitride (ceramic)
- Titanium Carbide coated 440C
Bearing retainer designs may include:
- stainless steel crown
- two-piece ribbon
- Torlon (polyamide-imide)
- Phenolic
Temperature and moisture resistant oils and greases are common lubricants. Engineers and product design teams work with customers to meet specific challenging environmental and operating needs of the aerospace bearing - the ball, the retainer, and the lubricant.
Reputable companies fabrication complies with ISO9001, AS9100:2004, FAA TSO-C149. Working with an Aircraft Bearings Certified facility, operating to meet ABEC, ABMA, and DFAR, tolerances and domestic manufacturing requirements is very important.
