6203-2RSH/C3LHT23 Bearing Product Overview & Core Advantages
The 6203-2RSH/C3LHT23 is a high-performance single row deep groove ball bearing designed for demanding industrial applications. This sealed bearing excels in providing reliable operation under radial loads and moderate axial loads in both directions. Its key advantages include extended service life due to effective sealing, a C3 radial internal clearance suitable for applications with thermal expansion, and compliance with ROHS and REACH environmental standards. The bearing is manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent quality and performance for general precision applications.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard series designation for a single row deep groove ball bearing with 17mm bore, 40mm OD, 12mm width. |
| 2RSH | Contact seals on both sides. The "H" designation indicates a high-temperature resistant sealing material, offering superior contamination protection. |
| C3 | Radial internal clearance greater than normal. Ideal for applications with shaft interference fits or where operational heat generation is expected. |
| LHT23 | Specifies the use of a high-temperature, synthetic hydrocarbon grease lubricant, suitable for the specified temperature range of -30°C to 120°C. |
6203-2RSH/C3LHT23 Bearing Structural Features & Performance Benefits
Constructed entirely from chrome steel, this bearing offers high strength and durability. The deep groove raceway geometry is optimized for handling radial dynamic loads up to 2147 lbf and facilitates smooth operation under combined loads. The 2RSH contact seals are a critical feature, effectively retaining the LHT23 grease and excluding contaminants, which significantly enhances bearing life and enables maintenance-free operation in many environments. The C3 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload. With a limiting speed of 17,000 rpm, it is well-suited for a wide range of industrial drives and machinery.
