If a Tempilstik is not available, you may test a hot bearing by which method?

• A. Carefully pass your hand near the bearing without touching it.
• B. Touch the bearing with bare skin to feel heat.
• C. Measure with a thermometer at the bearing surface.
• D. Shake the bearing to feel heat.

Answer: (A)

If a Tempilstik isn’t available, you rely on a quick, noncontact way to judge temperature. Gently bring the back of your hand near the bearing to sense whether it feels unusually hot. This lets you determine if the bearing is overheated without touching it, reducing the risk of burns and avoiding contamination or damage to the bearing. It’s a practical safety check you can perform in the field. Touching with bare skin can burn you and spread contaminants; using a thermometer at the surface isn’t practical in the field and may require equipment you don’t have; shaking the bearing won’t give a reliable indication of temperature and could mislead or cause harm.
