IV. Selection and Maintenance Suggestions
Selection Key Points
Load Calculation: Select the optimal size based on radial and axial loads to ensure maximum service life and prevent damage from overload.
Speed Matching: In high-speed applications, opt for 2RSH or open models, as the limiting speed of sealed bearings is inherently lower than their open counterparts.
Environmental Factors:
High Temperature: Choose the VA201 model, which features manganese phosphating treatment coupled with PAG grease, for reliable high-temperature performance.
Corrosion: For environments prone to corrosion, utilize 316 stainless steel material with a 2RS seal to ensure longevity and reliability.
Dust: Opt for 2Z or 2RS seal to effectively prevent dust penetration, maintaining optimal performance.
Installation Method: Ensure the fit tolerance between the shaft and bearing housing adheres to ISO standards to prevent improper clearance and interference.
Maintenance Precautions
Lubrication: For open bearings, regularly replenish with lithium-based grease (NLGI Grade 2). Sealed bearings are zero-maintenance, though grease integrity must be monitored to avoid high-temperature failure.
Seal Inspection: Regularly inspect the seal ring for aging or damage and replace promptly to maintain functionality.
Temperature Monitoring: When operating temperatures exceed 80ºC, reduce load or transition to a high-temperature model to prevent heat-related damage.
Vibration Detection: Detect abnormal vibrations as a sign of wear or incorrect installation, necessitating immediate maintenance to prevent further complications.
V. Alternative Models and Compatibility
International Standard:
ISO: 6203.
ANSI: 17mm x 40mm x 12mm, aligns with imperial models like 1703-2RS, ensuring easy integration.
Common Alternative Models:
With Seal: Opt for models like 6203-2Z, 6203-2RS, or 6203-2RSH for sealed performance in variable environments.
High Temperature: For superior temperature endurance, select 6203/VA201 or 6203/VA208 models.
Stainless Steel: Models like S6203-2Z, S6203-2RS are available in 304/316 stainless steel for robust, corrosion-resistant performance.
VI. Typical Faults and Troubleshooting
Fault Phenomenon Possible Causes Solutions
Abnormal Noise: Often caused by insufficient lubrication, bearing wear, or improper installation. Solutions include replenishing lubrication, replacing the bearing, and verifying installation correctness.
Excessive Temperature: Arises from overload, grease failure, or overly tight seals. Mitigate by reducing load, altering grease, or adjusting the seal.
Excessive Vibration: Typically due to inappropriate clearance or shaft misalignment. Address these by checking clearance and realigning the shaft.
Seal Leakage: Results from seal ring aging or installation damage. Remedies include replacing seal rings and refining installation processes.
