Product detailed description
Bearing - S 688 2Z GPR J GRW
S 688 2Z GPR J GRW stainless-steel bearing
S 688 2Z GPR J GRW is a miniature single-row deep-groove ball bearing with dimensions of 8 × 16 × 5 mm. The stainless-steel design provides greater corrosion resistance than standard bearing steel. Deep raceway grooves allow the bearing to carry radial loads and light axial loads in both directions.
Key features
- stainless-steel design for environments with increased corrosion-resistance requirements,
- 2Z – non-contact metal shields on both sides,
- shields help retain lubricant and reduce the ingress of larger contaminants,
- low-friction design for compact and precise mechanisms,
- manufactured by GRW, a specialist in miniature and high-precision bearings.

Selection and installation
This bearing is used in small drives, instruments and other compact mechanisms where limited installation space and increased corrosion resistance matter. The 2Z shields are not contact seals; where water, fine dust or aggressive media are present, the complete arrangement must provide suitable protection. When replacing the bearing, compare not only the dimensions but also the full S 688 2Z GPR J designation, as the additional characters may identify application-relevant execution details.
