6208-2RS1/C3W64

• 6208: Basic designation for a single row deep groove ball bearing with a 40mm bore and 80mm outside diameter.
• 2RS1: Indicates the bearing features two contact seals (one on each side), providing superior protection against contamination and retention of lubricant.
• C3: Specifies a greater radial internal clearance than normal (C0), suitable for applications with significant thermal expansion or where interference fits are used.
• W64: Denotes the bearing is lubricated with Solid Oil, a polymer matrix saturated with oil, ensuring long-term lubrication and eliminating leakage.

The single row design with deep raceway grooves provides high radial load capacity and the ability to accommodate axial loads from both directions. The use of high-grade chrome steel for the rings, balls, and cage ensures high strength and resistance to wear. The 2RS1 contact seals effectively shield the internal components from contaminants like dust and moisture, significantly enhancing operational reliability. The Solid Oil (W64) lubrication system is a key performance feature, offering a consistent lubricating film that does not leak or drip, even at high speeds, contributing to the bearing's limiting speed of 8,300 rpm. The C3 clearance provides operational stability in environments with fluctuating temperatures, preventing preload and potential seizure.

This versatile bearing is widely used across various industries due to its robust and sealed design. Common applications include:

• Electric Motors and Generators
• Industrial Gearboxes and Transmissions
• Material Handling Equipment (e.g., conveyor pulleys)
• Agricultural Machinery
• Automotive Components (e.g., alternators, idlers)
• General Machinery requiring a reliable, maintenance-free bearing solution.
