EZO 698ZZ dimensions
The basic dimensions are:
d: 8 mm
D: 19 mm
B: 6 mm
Complete dimensional specification:
8x19x6 mm
The compact cross-section allows the bearing to be installed in mechanisms where radial and axial installation space is limited.
What does 698ZZ mean?
698 - miniature deep groove ball bearing size with dimensions 8x19x6 mm.
ZZ - metal shields on both sides of the bearing.
The complete 698ZZ designation should be retained when identifying or selecting the bearing because other 698 variants may use different closure configurations.
EZO 698ZZ construction
EZO 698ZZ is a single-row deep groove ball bearing consisting of:
- inner ring,
- outer ring,
- balls,
- cage,
- metal shields on both sides.
Its deep raceway geometry is primarily designed to accommodate radial loads. Deep groove ball bearings can also accommodate axial loads within the operating limits of the specific bearing arrangement.
What does ZZ mean?
The ZZ designation identifies metal shields on both sides.
The shields help to:
- reduce the ingress of contaminants,
- protect the raceways and rolling elements,
- retain lubricant inside the bearing,
- provide protection while maintaining low running friction.
ZZ metal shields should be distinguished from the seals used in 2RS bearing versions.
698ZZ vs open 698
Both versions belong to the same basic bearing size but differ in closure design.
698ZZ - metal shields on both sides.
698 - open bearing version.
The ZZ version provides additional protection for the raceways and rolling elements against contamination.
698ZZ vs 698-2RS
The principal difference is the closure system.
698ZZ - metal shields on both sides.
698-2RS - seals on both sides.
The appropriate version should be selected according to contamination levels, required protection, operating speed and the conditions of the complete bearing arrangement.
Compact 8x19x6 mm design
EZO 698ZZ has an 8 mm bore, 19 mm outside diameter and 6 mm width.
Its compact dimensions make it suitable for small mechanisms and precision assemblies where the available bearing installation space is limited.
Selection should nevertheless consider operating load, speed and environmental conditions rather than dimensions alone.
Selection and interchangeability
Before selecting EZO 698ZZ, verify:
- complete 698ZZ designation,
- 8 mm bore diameter,
- 19 mm outside diameter,
- 6 mm width,
- ZZ metal shields,
- required load capacity,
- operating speed,
- environmental conditions,
- shaft and housing fits.
Matching 8x19x6 mm dimensions alone does not automatically confirm complete interchangeability between different bearing versions.
Installation
Before installation, ensure that the bearing, shaft and housing are clean.
When fitting the bearing onto a shaft, mounting force should be applied to the inner ring. When pressing it into a housing, force should be applied to the outer ring.
Mounting force should not be transmitted through the balls, and direct pressure on the ZZ metal shields should be avoided.
