608-2RS Ball Bearing

Sealed Deep Groove Ball Bearing for Smooth and Reliable Performance

The 608-2RS ball bearing is one of the most widely used deep groove ball bearings in light industrial and commercial applications. Designed with rubber seals on both sides, it helps protect internal components from dust, moisture, and other contaminants while maintaining smooth rotation and low operating noise.

Its compact dimensions, dependable performance, and cost-effective design make the 608-2RS bearing a popular choice for electric motors, conveyor rollers, fitness equipment, skate applications, automation systems, and various precision devices.

Manufactured from high-grade bearing steel and inspected throughout production, our 608-2RS bearings are suitable for OEM assembly, aftermarket replacement, and bulk industrial supply.

Key Features

Double-Sealed Protection

The rubber seals on both sides help retain lubricant and reduce the risk of contamination, making the bearing suitable for challenging operating environments.

Smooth and Quiet Operation

Precision-ground raceways and carefully selected steel balls contribute to stable rotation, low vibration, and reduced noise levels.

Pre-Lubricated for Immediate Use

Each bearing is supplied with high-quality grease, allowing for direct installation without additional lubrication.

Compact Yet Durable

Despite its small size, the 608-2RS bearing delivers reliable performance under both radial and moderate axial loads.

Suitable for High-Speed Applications

Optimized internal geometry supports efficient operation in equipment requiring consistent rotational performance.

Product Use

Core Application Areas of 607 2RS 607rs Mini Bearings

607 bearings are used in many concentrated application areas. Skateboards, principally longboards, are the biggest and most recognized application area for 607 bearings.

Skateboards use 608 bearings, but longboards use bigger wheels, needing more steady and load-bearing 607 bearings. Inline skates are also popular. Smooth, durable, and high-speed performance are what many mid to high end inline skates, particularly adult, use 607 bearings for. 607 also has many other applications in small, high-speed motors, such as drone motors, where the brushless motor spindles are expected to bear high speeds and some impact, as well as in RC model cars. Besides these, 607 bearings are used in small precision instruments and office equipment, like printers.
