| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Deep Groove Ball Bearing Series |
| 627 | Dimension Series Code (6: Extra Thin, 2: Light, 7: Bore Diameter 7 mm) |
| X | Contact Seal on Both Sides (Note: Specification data indicates "Open" seal type. The "X" suffix may denote a specific variant or internal designation. Please confirm seal type with technical datasheet.) |
W 627 X Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The bearing rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and durability in harsh or washdown environments.
- High-Speed Capability: The optimized deep groove raceway and precision manufacturing enable a high limiting speed of 63,000 rpm, ideal for small, fast-rotating spindles and instruments.
- Radial Load Performance: The single-row design is engineered to efficiently support radial loads, with a dynamic load rating of 70 lbf and a static load rating of 32 lbf.
- Precision & Low Friction: Built to P0 tolerance class with standard CN radial internal clearance, this bearing ensures smooth, low-friction rotation, contributing to energy efficiency and reduced vibration.
- Lightweight & Compact: With a minimal cross-section (13 mm OD, 3 mm width) and a weight of only 0.0015 kg, it is perfect for space-constrained and weight-sensitive applications.
W 627 X Bearing Typical Application Areas
- Precision Instruments: Optical encoders, measuring devices, and small laboratory equipment.
- Small Electric Motors: Miniature DC motors, stepper motors, and fan motors.
- Medical Devices: Dental handpieces, surgical tools, and pump drives requiring corrosion resistance.
- Office Automation: Printers, scanners, and copiers.
- Food & Beverage Equipment: Small conveyors and dispensers where stainless steel is mandated.
