Selecting Motor Bearings Is Just Like Finding A 'heart' for The Motor.‌

For motor factory owners, procurement managers, and engineers:
When vibration causes your motor yield rates to plummet, order delays, and customer complaints, have you ever considered that the culprit might be that inconspicuous little bearing?

Recently, I met a friend from a motor factory who was so stressed he was nearly tearing his hair out. To cut costs, they had opted for cheap bearings. Just six months after production started, their workshop sounded like a chaotic marketplace — the bearings clanked loudly when rotating, vibrations were strong enough to loosen screws, and there were even cases of seized bearings causing motors to smoke.

The procurement manager got chewed out by the boss daily, and assembly technicians sighed in exhaustion. When they tallied up the repair costs and production downtime, the losses were several times higher than the meager savings from those cheap bearings.

After consulting us, they finally identified the root cause:

• Low-precision bearings wore out quickly under prolonged use.

• Poor lubrication design led to rapid grease loss at high temperatures, increasing noise.

• Substandard materials couldn’t handle high-speed operation.

Kent Bearings offer solutions:

• P5/P6 precision grades and patented quiet structures (e.g., Model 6201 operates below 23 dB).

• Special heat treatment ensures stable performance at 10,000 RPM for 30,000 hours.

The real cost breakdown:
While cheap bearings seem cheaper upfront, their low precision causes:

• Excessive motor vibration → plummeting yield rates.

• Noise complaints → ruined customer experience.

• Constant rework → missed deadlines and wasted capital.

Many motor factories repeat this lesson: choosing cheap bearings to "save costs" only drowns them in hidden expenses. Selecting bearings is like choosing a "heart" for your motor — cheap ones may seem fine at first, but flaws emerge over time.

Is your motor’s "heart" still healthy?
