This bearing supports radial loads and moderate axial loads, offering versatile usage across various mechanical and industrial systems.

Core Benefits and Suitable Applications

Long Life, Low Maintenance, and Versatile Use

• Compact size for tight spaces — The 7x22x7 mm dimensions allow installation in small motors, hand tools, miniature gearboxes, small pumps, fans, and other devices with limited housing space.

• Sealed protection (2RS) ensures durability — Dual rubber seals retain lubricant inside and prevent ingress of contaminants, significantly extending service life and reducing maintenance frequency.

• Reliable performance under load — Deep groove geometry and hardened steel balls and races deliver smooth, low-friction rotation, consistent speed, and stability under radial and moderate axial loads.

• Wide range of applications — Suitable for electric motors, power tools, small machinery, conveyor rollers, household appliances, medical devices, and precision equipment requiring dependable bearing support.

• Ready-to-install bearing unit — Standard dimensions and sealed design enable quick and straightforward installation in housings or shafts, making it an efficient solution for B2B procurement and maintenance operations.

Detailed Product Description

The SKF 627 2RS 7x22x7 mm deep groove ball bearing is a high-quality, compact bearing designed for small-scale machinery and devices where space is constrained but performance and reliability cannot be compromised. Its deep groove ball construction ensures that both radial and moderate axial loads can be handled smoothly, making the bearing suitable for a variety of applications — from small electric motors and precision gearboxes to tiny pumps, fans, conveyor rollers and power tools.

The dual rubber seals (2RS) provide effective protection against dust, metal shavings, moisture, and other contaminants, while retaining lubricant inside the bearing. This sealing significantly reduces maintenance requirements, prolongs bearing life, and ensures stable performance even in harsh or dirty environments. The sealed design also helps maintain smooth rotation and limits friction and wear over time.

Despite its compact size, SKF 627 2RS offers stable performance under continuous operation and varying loads. Its hardened steel components deliver durability and reliability, enabling long operational periods without the need for frequent replacements — an important advantage for industrial users and maintenance services looking to minimize downtime.

Thanks to standard sizing and sealed construction, this bearing integrates seamlessly into existing housings or shaft assemblies. Whether used in small motors, hand tools, household appliances, industrial machinery, or prototyping equipment, SKF 627 2RS offers a ready-to-use solution that balances compactness, durability, and ease of installation.

In summary, SKF 627 2RS is a dependable sealed ball bearing — ideal when compact dimensions, reliable rotation, durability and low maintenance are needed.
