D: 9 mm

3x9x3 mm
When selecting this bearing, the flange geometry must also be considered. Matching the basic 3x9x3 mm dimensions alone does not guarantee mounting compatibility with a non-flanged bearing.
What does SF 693 H mean?
SF 693 H identifies a specific miniature EZO bearing version.
693 identifies the bearing size.
The F element of the designation identifies the flanged outer-ring construction in this bearing family.
The absence of ZZ or 2RS indicates an open design.
The complete SF 693 H EZO designation should be retained when identifying or selecting a replacement, as visually similar miniature bearings may differ in material, flange geometry and closure design.
Construction
EZO SF 693 H is a miniature single-row deep groove ball bearing consisting of:
- inner ring,
- flanged outer ring,
- balls,
- cage,
- open bearing construction.
The deep raceway geometry is primarily designed to accommodate radial loads and can also accommodate limited axial loads in both directions within the operating limits of the bearing arrangement.
Flanged outer ring
The flange is one of the key construction features of SF 693 H.
It facilitates axial positioning of the bearing against the housing or mounting bore. In miniature mechanisms, a flanged outer ring can simplify the housing design and help locate the bearing without requiring an additional axial locating feature.
The actual flange dimensions must be considered when designing or verifying the housing.
Open design
SF 693 H does not include a ZZ or 2RS suffix and is therefore an open bearing version.
An open bearing provides direct access to the rolling elements and raceways. The lubrication method and protection against contamination should therefore be considered as part of the complete bearing arrangement.
SF 693 H vs SF 693 H ZZ
These versions should not be considered identical.
SF 693 H - open version.
SF 693 H ZZ - version with metal shields on both sides.
The closure type can affect protection against contamination, lubricant retention and operating characteristics.
Selection and interchangeability
Before selecting EZO SF 693 H, verify:
- complete manufacturer designation,
- 3 mm bore,
- 9 mm outside diameter,
- 3 mm width,
- flanged outer ring,
- required flange dimensions,
- open construction,
- required load capacity,
- operating speed,
- lubrication conditions.
With miniature bearings, even small dimensional or construction differences can prevent interchangeability.
Installation
Miniature bearings require careful handling during installation.
When fitting the bearing onto a shaft, mounting force should be applied to the inner ring. When pressing the bearing into a housing, force should be applied to the outer ring.
Mounting force should not be transmitted through the balls, and direct impact on the flange should be avoided.
