SKF 627 2RS C3 7x22x7 mm Deep Groove Ball Bearing

Compact Sealed Bearing - Specifications & Typical Use

Small Form Factor, High Reliability for Precision Equipment

The SKF 627 2RS C3 is a deep groove ball bearing with dimensions 7 mm (inner diameter) x 22 mm (outer diameter) x 7 mm (width), equipped with dual rubber seals (2RS) and a slightly increased internal clearance (C3). Its compact size combined with protection against dust, debris, and moisture makes it ideal for applications requiring reliable, smooth rotation in confined spaces, such as small motors, power tools, miniature gearboxes, or precision devices.

Advantages & Application Areas

Durable, Versatile and Low-Maintenance Bearing Solution

• Compact dimensions for tight installations — 7x22x7 mm size allows use in small motors, handheld tools, miniature transmissions, fans, pumps, or compact industrial devices.

• Sealing system (2RS) for contamination resistance — Rubber seals retain lubricant and prevent ingress of dirt, dust, and water, extending bearing life and reducing maintenance frequency.

• Balanced load handling and smooth rotation — Deep groove geometry delivers stable handling of radial loads and light axial loads, with low friction and minimal vibration.

• Enhanced operational resilience — The C3 internal clearance compensates for slight shaft misalignments and thermal expansions, allowing stable performance under variable conditions.

• Wide applicability across industries — Suited for electric motors, tools, small machinery, conveyor rollers, pumps, fans, appliances and precision equipment where reliability and compactness are key.

Detailed Product Description

The SKF 627 2RS C3 7x22x7 mm deep groove ball bearing represents a high-quality, space-saving bearing solution crafted for compact equipment and precision mechanisms where space is limited, but reliability, smooth rotation, and minimal maintenance are essential. Its sealed design (2RS) ensures that lubricant remains inside while preventing contamination from dust, moisture, or debris — a critical advantage in demanding or dirty environments.

With its deep groove ball design, the bearing provides stable radial load support and can handle modest axial loads, ensuring consistent shaft rotation and minimal vibration. The slightly increased internal clearance (C3) allows for thermal expansion and tolerates minor misalignments — beneficial in applications subject to temperature changes or variable loading. This translates into greater reliability, longer lifespan, and reduced risk of premature failure.

The small 7x22x7 mm form factor makes SKF 627 2RS C3 especially suitable for small electric motors, gearboxes, handheld tools, small pumps, fans, conveyor rollers, and other compact devices — where standard larger bearings cannot be used. Its sealed and ready-to-install nature accelerates maintenance, upgrades, or production line assembly, reducing downtime and ensuring consistent performance across many units.

For businesses seeking a compact, durable, and low-maintenance bearing solution for industrial or commercial tasks, SKF 627 2RS C3 offers the ideal balance of performance, longevity, and ease of integration.

FAQ - Frequently Asked Questions

Q: Is SKF 627 2RS C3 suitable for small motors and handheld tools?
A: Yes — its compact size, sealed design, and balanced load capacity make it great for small motors, power tools, fans, and similar devices.

Q: Will the sealing protect the bearing in dusty or moist environments?
A: Absolutely — dual rubber seals keep lubricant inside and block dust, debris, and moisture, extending bearing service life and reducing maintenance.

Q: What loads can this bearing handle?
A: It handles radial loads and light axial loads reliably, making it suitable for many small-scale mechanical applications.

Q: Does the slight C3 clearance improve performance under variable conditions?
A: Yes — the extra clearance helps compensate for thermal expansion and minor misalignment, providing stable operation under temperature changes or minor shaft displacement.

Q: Is mounting this bearing complicated?
A: No — standard dimensions and sealed ready-to-install design make it easy to integrate into shafts, housings, or equipment assemblies without additional modifications.
