6203 VV NSK 17x40x12 Deep Groove Ball Bearing

Product Overview

6203 VV NSK is a single-row deep groove ball bearing with dimensions of 17x40x12 mm, equipped with non-contact rubber seals on both sides. The NSK VV designation identifies a low-friction sealing arrangement in which the seal lip does not contact the inner ring. This design reduces friction and heat generation while protecting the rolling elements and retaining the factory-applied lubricant.

Industrial Applications

NSK 6203 VV is used in electric motors, industrial fans, blowers, HVAC equipment, pumps, conveyors and compact drive systems. The non-contact sealing design is particularly suitable for rotating equipment requiring low friction and higher operating speeds. Deep raceway grooves enable the bearing to accommodate radial loads together with axial loads acting in both directions.

Construction

The bearing uses a single row of balls operating in deep raceway grooves. VV seals are installed on both sides and provide non-contact protection without rubbing against the inner ring. This configuration reduces seal friction and heat generation while helping retain grease and restrict the entry of contaminants into the bearing arrangement.

Material

The inner ring, outer ring and rolling elements are manufactured from bearing steel designed for repeated rolling contact and wear resistance. A pressed steel cage separates and guides the balls during operation. Bearing service life depends on load, rotational speed, operating temperature, shaft and housing fits, lubrication and contamination conditions.

Why Industrial Buyers Choose 6203 VV NSK

6203 VV NSK supports OEM replacement, maintenance stock and industrial service where standard 17x40x12 mm dimensions and low seal friction are required. The VV configuration is suitable for machine rebuilding, production support and fleet maintenance involving motors, fans and rotating assemblies. Standard 6203 dimensions also simplify technical identification, inventory management and replacement planning.

Operational Advantages

Non-contact VV seals reduce friction generated by the sealing system. Double-sided sealing helps retain lubricant inside the bearing. Low seal resistance supports applications requiring higher rotational speeds. Deep raceways accommodate radial and axial loads in both directions. Factory lubrication reduces routine maintenance requirements. Standard 17x40x12 mm dimensions simplify replacement identification.

FAQ

What does VV mean on an NSK 6203 bearing? VV identifies NSK non-contact rubber seals fitted on both sides of the bearing. What is the difference between NSK 6203 VV and 6203 DDU? VV uses non-contact seals to reduce friction, while DDU uses contact seals where stronger protection against contamination is required. Is NSK 6203 VV suitable for higher rotational speeds? The non-contact VV design reduces seal friction, making it suitable for higher-speed applications within the specified operating limits of the bearing. What are the dimensions of NSK 6203 VV? The bearing has a 17 mm bore diameter, 40 mm outside diameter and 12 mm width. Where is NSK 6203 VV commonly used? Typical applications include electric motors, industrial fans, blowers, HVAC equipment, pumps, conveyors and compact drive systems.
