Storage Conditions of BNR Precision Bearing

Store bearings flat, in a vibration-free, dry area with a cool, steady temperature.
Control and limit the relative humidity of the storage area as follows:
• 75% at 20 °C (68 °F)
• 60% at 22 °C (72 °F)
• 50% at 25 °C (77 °F)
Keep bearings in their original unopened packages until immediately prior to mounting to prevent the ingress of contaminants and corrosion.
Bearings that are not stored in their original packaging should be well protected against corrosion and contaminants.

FAQ

 

Q: What are precision bearings used for?

A: These bearings are often used in metal cutting and woodworking machinery spindles, vacuum pumps, precision ball screws, printing machinery, medical devices, aerospace, high speed rolling mills, and high speed turbochargers.

Q: What tool should be used to remove precision bearings or gears?

A: The most common types of tools for removing bearings are two- and three-arm bearing pullers, or external pullers. They range from one- to forty-ton capacity and feature two or three jaws that are slim and tapered, allowing the ends to get easily behind the bearing to its race.

Q: How long do precision bearings typically last?

A: 1–5 years on average. Lifespan depends on use: proper lubrication and clean conditions extend it, while overload or contamination cut it short.

Q: Do precision bearings need specialized installation tools?

A: Not always—they use the same pullers/wrenches as standard bearings. But you must ensure shaft-housing coaxiality (misalignment ruins precision).

Q: What is the proper way to store a new unused bearing?

A: Store unused bearings horizontally in their original packaging in a clean, dry area at room temperature. This prevents moisture, dust, and dirt from entering the bearings prior to installation. Dropping or mishandling bearings can cause unseen damage that might not manifest until a later date.
