Deep Groove Ball Bearings: Core Advantages & Selection Guide
Bearing Suffix Definitions
- RS: Single-side contact rubber seal
- 2RS: Double-side contact rubber seal
- RZ: Single-side non-contact rubber seal
- 2RZ: Double-side non-contact rubber seal
- Z: Single-side dust cover

- N: Outer ring with retaining groove
Why Choose Deep Groove Ball Bearings?
✅ Versatile Load Capacity
- Mainly bears radial loads and supports bidirectional axial loads simultaneously
- Point-contact structure enables higher speed limits than roller bearings, ideal for high-speed motor spindles
- Can replace angular contact bearings by increasing radial clearance to enhance axial load capacity
✅ Economic & Reliable
- Standardized mass production ensures strong price competitiveness
- Open-type bearings support lifetime lubrication; sealed models require zero maintenance
- Service life reaches 30,000–50,000 hours under rated working conditions
✅ Flexible Installation
- Compensates 2′–10′ shaft deflection to offset installation errors
- 11 structural variants available: open, shielded (Z/ZZ), sealed (RS/2RS), snap ring (N) types, etc.
- Size range covers 1mm bore miniature bearings to over 440mm outer diameter large bearings

FAQ Highlights
Deep Groove vs Angular Contact BearingsDeep groove bearings have a 0° contact angle, focusing on radial loads with limited axial capacity; they are cheaper and faster. Angular contact bearings (15°/25°/40° contact angles) handle high single-direction axial loads and are used in pairs.
Extend Bearing Service LifeAvoid overloading (≤30% of dynamic load rating); ensure clean installation; use proper grease and replenish periodically; control temperature within the allowable range; use dedicated installation tools to prevent impact damage.
High-Speed Operation of Sealed Bearings2RS sealed bearings have 15–20% lower speed limits than open types due to seal friction. For speeds over 10,000 RPM, choose Z/ZZ shielded bearings or open bearings with oil lubrication.
Motor Bearing Temperature LimitsTemperature rise is normal; keep it within ambient +55°C (max 95°C). Excessive heat indicates problems with lubrication, alignment, load or clearance.
6205 vs 6305 BearingsBoth have a 25mm bore; 6305 (62mm OD, 17mm width) has 40% higher load capacity than 6205 (52mm OD, 15mm width). Choose 6305 for heavy loads with sufficient space; 6205 for space constraints or high-speed needs.
