6208-2RS1 N/C 3 HT51 Bearing Product Overview & Core Advantages
The 6208-2RS1 N/C 3 HT51 is a single row deep groove ball bearing designed for robust performance in demanding applications. As a sealed metric bearing, its primary advantage lies in its ability to handle significant radial loads while offering protection from contamination. The bearing features a standard CN radial internal clearance and is manufactured to ABEC 1 | ISO P0 tolerance class, ensuring reliable operation and interchangeability. Its compact design and high load capacity make it an excellent choice for applications requiring durability and long service life without maintenance.
Model Code Breakdown
- 6208: Basic series number indicating a medium duty, single row deep groove ball bearing with a 40mm bore and 80mm outside diameter.
- 2RS1: Designates that the bearing is equipped with two (2) contact rubber seals (RS1) on both sides, providing effective protection against contaminants and retaining lubricant.
- N/C 3: Indicates a specific radial internal clearance group (C3), which is larger than the standard CN clearance, making it suitable for applications with higher operational temperatures or where fits result in a reduction of internal clearance.
- HT51: Specifies the use of a high-temperature, synthetic hydrocarbon grease lubricant, suitable for the specified temperature range of -30°C to 120°C.
6208-2RS1 N/C 3 HT51 Bearing Structural Features & Performance Benefits
The 6208-2RS1 is engineered for performance and reliability. Its single row deep groove raceway geometry is optimized for high radial dynamic load capacity, rated at 6542 lbf. The chrome steel construction of the rings, balls, and cage provides high strength and wear resistance. The contact rubber seals (2RS1) are a critical feature, effectively shielding the internal components from dust, dirt, and moisture, thereby extending the bearing's lifespan in harsh environments. The combination of C3 radial internal clearance and HT51 grease ensures stable performance across a wide temperature range and under varying operational conditions, contributing to a limiting speed of 8,300 rpm. This design results in a maintenance-free solution for the majority of its service life.
