RE20030 Crossed Roller Bearing - FAQ
Can the RE20030 bearing be customized for special environments?
Yes. The RE20030 can be tailored with different cage materials, precision grades (P5–P2), and surface treatments such as black oxide or nickel plating. It's also available with cleanroom-compatible lubricants for semiconductor or optical inspection systems.
How is the RE20030 bearing shipped and protected during delivery?
Each bearing is individually vacuum-sealed and packed in anti-rust film with shock-proof cushioning. For large or bulk orders, bearings are safely placed in export-grade wooden boxes to prevent vibration or damage during international transport.
What internal clearance is used in the RE20030 bearing?
The RE20030 is manufactured with a controlled internal clearance optimized for rigidity and smooth motion. Clearance values are carefully selected during production to ensure proper preload after installation, helping maintain stiffness while preventing excessive friction or heat generation.
What factors influence the service life of the RE20030?
Service life is influenced by load magnitude, rotational speed, lubrication quality, mounting accuracy, and operating environment. When correctly selected and installed, the RE20030 can provide long-term stable performance in high-precision applications.
