When pressing on a bearing, you should?

• A. Apply pressure against the outer ring.
• B. Strike the bearing with a hammer.
• C. Press on the opposite side only.
• D. Apply pressure against the inner ring and exert slow, even force.

Answer: (D)

When you press a bearing, you want the load to go through the ring that will move without risking damage to the rolling elements or cage. If you’re seating the bearing on a shaft, press on the inner race so the inner race slides smoothly onto the shaft while the outer race stays supported in the housing. Use a proper press or driver with flat, full-face contact on the inner race, and apply slow, steady, even force with the bearing aligned squarely. This minimizes misalignment, prevents cocking, and avoids denting or brinelling of the races. Pressing on the outer race or hammering the bearing can damage the races or balls, and pressing from the wrong side can misalign things, so the recommended approach is to press the inner race with slow, even force.
