| LHT55 | High-temperature grease lubrication (-30°C to 120°C) | Extended lubrication intervals and thermal stability |
6203-2RSH/C3LHT55 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from high-grade chrome steel for rings, balls, and cage, ensuring dimensional stability and wear resistance under demanding operating conditions.
Enhanced Sealing Performance: The double contact seals (2RSH) provide effective protection against contaminants while retaining lubricant, significantly extending bearing service life in harsh environments.
Optimized Internal Clearance: The C3 radial clearance accommodates thermal expansion differences between shaft and housing, preventing premature failure due to excessive preload in high-temperature applications.
High-Temperature Capability: Pre-lubricated with LHT55 grease that maintains stable viscosity and lubricating properties across the entire operating temperature range from -30°C to 120°C.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent performance and reliable operation in various industrial applications.
6203-2RSH/C3LHT55 Bearing Typical Application Areas
Electric Motors: Ideal for small to medium-sized industrial motors requiring reliable radial load support and contamination protection.
Industrial Pumps: Suitable for centrifugal and circulation pumps where sealed construction prevents fluid ingress and extends service life.
Material Handling Equipment: Used in conveyor systems, rollers, and pulleys where consistent performance under varying loads is essential.
