A deep groove ball bearing is the most common and versatile type of bearing, featuring deep, circular grooves in its inner and outer rings that allow it to handle both radial (sideways) and axial (thrust) loads in both directions, making them ideal for electric motors, appliances, and tools due to their low friction, high speed capability, and robust, simple design.
Deep Groove Ball Bearings stand out for their universal adaptability and outstanding performance, with core features as follows:
Strong Universal Load-Bearing Capacity:Can simultaneously bear radial loads and small bidirectional axial loads (≤15% of radial load), eliminating the need for additional thrust bearings in most general machinery scenarios. This versatility covers over 90% of industrial and civilian application needs.
High-Speed Adaptability & Low Friction：Optimized raceway and cage design minimize frictional resistance (friction coefficient ≤0.0012). With grease lubrication, the maximum limiting speed reaches up to 6000 r/min; with oil lubrication, it can reach 8000 r/min—20% higher than bearings of the same size, adapting to high-speed operation scenarios such as electric motors and precision spindles.
Compact & Rigid Structure：The integral inner/outer ring design enhances structural rigidity and reduces cumulative assembly errors. With a small size and light weight, it offers high load-bearing density in limited installation space, making it ideal for equipment with space constraints.
Low Noise & Stable Operation：Precision-ground raceways (surface roughness Ra≤0.02μm) and polished steel balls ensure smooth operation with noise ≤50 dB. This meets the silent requirements of household appliances, medical equipment, and precision machinery.
Long Service Life & Reliability：Bearing rings and steel balls are primarily made of GCr15 high-carbon chromium steel, with SUS440C stainless steel available for corrosive environments. Surface hardening treatment and optimized contact design extend fatigue life by 30% compared to conventional bearings, ensuring long-term continuous operation.
Wide Customization Capabilities：Supports multi-dimensional non-standard customization: non-standard size adjustment (inner diameter/outer diameter/width), corrosion-resistant material modification (SUS440C), high/low-temperature lubrication solutions, seal type upgrades (composite seals), and cage material customization (high-speed/silent dedicated), fully meeting personalized application needs.
Cost-Effective Import Substitution:Technical specifications (load capacity, precision, service life) fully match international brands, with a 20%-30% lower procurement cost. Stable supply chains and mature production technology make it an ideal import substitution solution for general machinery.

The price of Deep Groove Ball Bearings is determined by multiple interrelated factors, with core influences as follows:
Size & Load Rating:Size is a primary pricing driver. The standard product line covers inner diameter 150–1400 mm, outer diameter 190–1700 mm, and width 20–132 mm. Larger bearings consume more raw materials and require more complex precision machining, leading to significantly higher costs. Bearings with ultra-high radial dynamic load ratings (above 2000 kN) also command a premium due to reinforced raceway structures.
Precision Grade:Precision grades follow the hierarchy P0 < P6 < P5 < P4. High-precision P4/P5 grade bearings require stricter grinding, multi-round testing, and strict sorting, with a higher production rejection rate. Their prices are 40%-70% higher than standard P0 grade bearings.
Material Selection Standard:GCr15 high-carbon chromium steel is the most cost-effective option; upgrading to SUS440C stainless steel for corrosion resistance increases raw material costs by 50%-80%. Cage material also affects pricing: brass cages are more expensive than reinforced Nylon 66 or stamped steel cages.
Structural Design & Seal Configuration:Open-type bearings are the most economical; adding contact seals (2RS/ZZ) increases costs by 15%-30%, while non-contact seals (Z/RS) add 10%-20%. Full-complement designs for heavy loads are pricier than cage-type bearings due to more steel balls and specialized raceway processing.
Lubrication Solutions:Standard lithium-based grease is included in base pricing; high-temperature (≤150°C) or corrosion-resistant grease increases costs by 20%-40%.
Order Quantity & Delivery Time:Bulk orders (≥100 pieces) qualify for a 15%-25% quantity discount. Small-batch orders (≤30 pieces) or urgent orders (delivery within 7 days) incur additional production and logistics costs, increasing the unit price by 20%-35%.
To select the optimal Deep Groove Ball Bearing for your equipment, comprehensively evaluate the following key factors:
Working Condition Matching:Clarify core parameters radial/axial load magnitude, operating speed, working temperature (-40°C to +150°C for standard models), and environmental conditions (clean, dusty, corrosive). Note that the bearing can only bear small axial loads—for large axial loads, it must be used in combination with thrust bearings.
Size & Precision Confirmation:Determine boundary dimensions (inner diameter d, outer diameter D, width B) strictly according to equipment design drawings. Select the precision grade based on application: P0/P6 for general machinery, P5/P4 for precision equipment such as servo motors and medical devices.
Material & Seal Selection:For standard working conditions, GCr15 steel and open/sealed (2RS/ZZ) designs are cost-effective. For corrosive environments, choose SUS440C stainless steel + corrosion-resistant grease + 2RS contact seals; for high-speed scenarios, select non-contact seals (Z/RS) to reduce friction.
Load & Speed Capacity Verification:Ensure the bearing’s radial dynamic load rating (Cr) and static load rating (Cor) exceed actual working loads by 1.2–1.5 times to reserve a safety margin for shock loads. Verify that the limiting speed (grease/oil lubrication) matches the equipment’s maximum operating speed, avoiding overspeed-induced failures.
Supplier Qualification Assessment:Prioritize professional suppliers with mature production capabilities, such as NewBee Transmission. Verify ISO9001 quality certification, advanced production equipment (CNC precision grinders, integral heat treatment lines), and comprehensive product testing reports. Evaluate after-sales service capabilities, including warranty periods and technical support.
Cost-Effectiveness Balance:Avoid over-specifying: select standard materials and precision grades for non-critical equipment to control costs. Domestic brands like NewBee Transmission offer performance comparable to international brands (e.g., SKF, NSK) at 20%-30% lower prices, ensuring stable supply and cost savings.

Proper installation, lubrication, and maintenance are critical to maximizing the service life and performance of Deep Groove Ball Bearings. Key precautions are as follows:
Standardized Installation Operation：Before installation, thoroughly clean the bearing, shaft, and housing bore to remove burrs, oil stains, and impurities. Use specialized pressing tools for assembly, applying force evenly on the ring with interference fit (shaft h7/housing bore H8). Strictly prohibit hammering or impact knocking, which causes raceway deformation and precision loss. Ensure correct alignment of inner and outer rings to avoid uneven load distribution.
Scientific Lubrication Management：Select lubricants based on temperature, speed, and load: use heavy-duty lithium-based grease for standard conditions; high-temperature special grease for environments ≤150°C; corrosion-resistant grease for humid/corrosive settings. Open-type bearings require grease replacement every 1000–2000 working hours; sealed bearings should be inspected regularly for leakage, with timely seal and grease replacement. Avoid over-lubrication (causes overheating) or insufficient lubrication (leads to dry friction).
Real-Time Operation Monitoring：During equipment operation, continuously monitor the bearing’s temperature, vibration, and noise. The normal operating temperature ranges from 30°C to 80°C, with a temperature rise not exceeding 8°C. Abnormal temperature spikes, vibration, or noise may indicate misalignment, overload, or lubrication failure—shut down equipment immediately for inspection to prevent catastrophic damage.
Proper Storage & Handling：Store bearings in a clean, dry, and ventilated environment with relative humidity ≤60%, avoiding contact with corrosive substances, direct sunlight, and strong magnetic fields. Store horizontally in original packaging to prevent ring deformation, and prohibit heavy stacking. During transportation, use shockproof packaging to avoid collision, dropping, or severe vibration, preserving precision and structural integrity.
Regular Inspection & Maintenance：Conduct periodic disassembly inspections according to equipment operating cycles. Check for raceway/steel ball wear, cage integrity, seal condition, and lubricant quality during inspection. If abnormal wear, pitting, or deformation is found, replace the bearing promptly to avoid secondary damage to host equipment. After inspection, clean components thoroughly with non-corrosive cleaning agents, reapply qualified lubricant, and reinstall correctly.
