W 6305-2RS1/VT378

• W: Indicates a bearing with a stainless steel design for enhanced corrosion resistance.
• 6305: The basic bearing designation, specifying a single row deep groove ball bearing with a 25mm bore, 62mm OD, and 17mm width.
• 2RS1: Signifies that the bearing is fitted with two integral contact seals made from NBR rubber. These seals provide superior protection against dust and moisture compared to non-contact shields.
• VT378: Denotes that the bearing is pre-lubricated with a specific, high-quality grease. This lubrication is tailored for the specified temperature range and contributes to the bearing's ready-to-install, maintenance-free characteristics.

The bearing's performance is derived from its specific construction. The deep groove raceway and stainless steel construction are fundamental to handling radial dynamic loads up to 4002 lbf. The chrome steel cage ensures stable ball guidance, contributing to smooth operation. A key feature is the 2RS1 contact seals, which effectively retain the VT378 grease and exclude contaminants, enabling reliable operation in challenging environments without re-lubrication. The combination of ABEC 1 precision and standard radial internal clearance (CN) ensures consistent performance and easy installation in a wide range of applications.

This bearing is ideally suited for applications where corrosion resistance and sealed-for-life operation are critical. Common uses include:

• Food and Beverage Processing Equipment
• Medical and Pharmaceutical Machinery
• Chemical Handling Pumps and Mixers
• Marine and Washdown Environments
• Agricultural machinery
• Conveyor systems in humid or corrosive atmospheres
