6306-2RS1/LHT23

• 6306: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 30mm bore, 72mm outside diameter, and 19mm width.
• 2RS1: Signifies that the bearing is fitted with two contact seals (RS1 type) on both sides. These seals provide superior protection against the ingress of moisture and solid contaminants compared to non-contact shields.
• LHT23: Indicates the bearing is pre-lubricated with LHT23 high-performance grease. This grease is designed for a wide temperature range (-30°C to +120°C), offering excellent stability and long-term lubrication.

The 6306-2RS1/LHT23's performance stems from its optimized design and material selection. The deep groove raceway and high-quality chrome steel construction for rings, balls, and cage provide high radial dynamic load rating (6002 lbf) and static capacity (3372 lbf). The contact seals (2RS1) effectively retain grease and exclude pollutants, significantly enhancing bearing life in harsh environments. Combined with the LHT23 grease, this configuration creates a maintenance-free solution, capable of operating at a limiting speed of 9,600 rpm. The standard CN radial internal clearance ensures reliable performance under normal operating conditions.

This versatile and robust bearing is commonly specified in a variety of industrial machinery and equipment, including:

• Electric Motors and Generators
• Industrial Gearboxes and Transmissions
• Material Handling Conveyors
• Agricultural Machinery
• Automotive Components (e.g., alternators, pumps)
• Ventilation and Fan Systems
