What should be used when handling bearings and why?

• A. Leather Gloves To Protect Hands
• B. Lint-Free Cotton Or Synthetic Rubber Gloves To Avoid Contamination
• C. Bare Hands For Tactile Feedback
• D. Wool Gloves To Keep Hands Warm

Answer: (B)

Handling bearings requires strict contamination control because even tiny fibers or skin residues can cause scoring, corrosion, or premature wear of the bearing surfaces. The best practice is to wear gloves that are lint-free and do not shed fibers or powders, such as lint-free cotton or synthetic rubber gloves. These gloves create a clean barrier, preventing skin oils and sweat from contacting the bearing and minimizing particulate contamination. They also reduce the risk of leaving behind fibers that could enter the bearing interface.

Leather gloves can shed particles, and bare hands leave oils and moisture that can affect lubrication and performance. Wool gloves shed fibers and can trap contaminants. Powdered gloves introduce glove powder into the bearing area, which is undesirable. Using lint-free cotton or synthetic rubber gloves provides clean handling and protects the bearing surfaces.
