Sealing and Lubrication
The 2RS suffix designates a pair of nitrile rubber contact seals (NBR on SPCC steel backing), one pressed into each side. These seals lock the factory grease charge inside the bearing cavity and block moisture, dust, and fine debris from entering the raceway. The bearing ships pre-lubricated and requires no field regreasing across its full service temperature range of -40C to 120C.
Performance
The 695 2RS miniature deep groove ball bearing uses a single-row raceway profile, which takes both radial and axial loads within a compact envelope. Rings and balls are GCr15 chrome steel, hardened and ground to ABEC-3 tolerance. This bearing is part of the deep groove ball bearing portfolio at Yuanhe, spanning bore sizes from 3mm to 100mm. Static load rating 0.43kN, dynamic load rating 0.2kN. Maximum rated speed is 47,000 RPM. Noise and vibration levels are held low through controlled raceway roundness and ball grade selection, consistent with precision bearing production methods.
OEM and Customization
Internal radial clearance options (C2, CN, C3) are available for production quantities. Alternative grease fills for elevated temperatures or specific speed profiles can be factory-filled on request. 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.

Frequently Asked Questions
FAQ
What grease does the 695 2RS ship with? +
The 695 2RS comes factory-filled with low-noise polyurea grease suitable for -20C to +120C operation. The rubber seals retain this grease for the life of the bearing. Alternative greases include high-temperature polyurea (up to +150C), food-grade grease for incidental food contact, and low-torque grease for battery-powered devices.
Can the 695 2RS operate in wet or submerged conditions? +
The 695 2RS has contact rubber seals that block moisture and fine dust, but it is not rated for continuous submersion. Occasional splash exposure is acceptable. For wet or washdown environments, specify stainless steel rings (SUS440C) with appropriate grease. The 2RS seals will protect against water spray but not pressure washing or immersion.
What is the breakaway torque of the 695 2RS? +
The 695 2RS rubber seals add a small amount of friction compared to the open or ZZ variants. Breakaway torque is approximately 0.2 to 0.5 N-mm at room temperature with standard grease. This seal drag is negligible for most small motor and instrument applications but may matter in ultra-low-power battery devices.
How does the 695 2RS prevent lubricant leakage? +
The nitrile rubber (NBR) seals contact the inner ring with a light lip pressure. This contact creates a positive seal that keeps grease inside the bearing and contaminants outside. The seal lip is designed to maintain contact pressure throughout the bearing life. Unlike metal shields, 2RS seals do not rely on a labyrinth gap – they form a physical barrier.
