Sealing and Lubrication

The 2RS designation indicates double nitrile rubber seals (NBR+SPCC) on both sides of this 4mm bore bearing. These contact seals retain the factory-packed high-temperature grease and block dust and moisture ingress. The bearing is lubricated for life; no relubrication is required across its service temperature range of -40C to 120C.

Performance

The 694 2RS miniature deep groove ball bearing uses a single-row raceway that handles combined radial and axial loads within a 4x11x4mm envelope. Rings and balls are GCr15 chrome steel, hardened and ground to ABEC-3 tolerance. This bearing is one of the smallest in the deep groove ball bearing range at Yuanhe. Dynamic load rating 0.15kN, static load rating 0.276kN. Rated for 52,000 RPM with low noise characteristics, manufactured to precision bearing standards.

OEM and Customization

Internal radial clearance options (C2, CN, C3) and custom grease fills available for volume orders. Batch traceability is maintained throughout production; dimensional inspection reports and material certificates ship with volume orders. Submit your bearing specification for pricing and lead time.

Applications

Dental handpieces and micro medical devices

Model aircraft servos and micro actuators

Precision instrumentation and optical equipment

Miniature fans

Small office equipment spindles

Frequently Asked Questions

What is the load rating of a 694 2RS bearing? +

Dynamic load rating is 0.15kN, static load rating is 0.276kN. Maximum operating speed is 52,000 RPM. For applications exceeding these limits, contact us for a bearing selection review.

What does 2RS mean on a bearing? +

2RS indicates two rubber seals, one on each face. These nitrile rubber (NBR) contact seals bonded to SPCC steel cores retain the factory grease and block external contaminants. 2RS bearings are sealed for life and require no field regreasing.

Can I order 694 2RS bearings with different clearance? +

Yes. Standard internal clearance is CN. C2 and C3 are available for volume production orders. Specify your clearance requirement when requesting a quote.

What is the difference between 694 ZZ and 694 2RS? +

694 ZZ uses metal shields for lower friction and higher speed with moderate dust protection. 694 2RS uses rubber contact seals for tighter contaminant exclusion. Choose 2RS when moisture or fine particulate is present in the operating environment.
