📋 Overview
Single row deep groove ball bearings are the most widely used rolling bearing type in global industrial scenarios, accounting for over 65% of total bearing shipments in 2026. This guide sorts out full details for you to make informed purchase and operation decisions.
What Is Single Row Deep Groove Ball Bearing: Core Definition
Single row deep groove ball bearing is a standardized radial rolling component for low to medium load rotary motion transmission. With simple structure, high interchangeability and low manufacturing cost, it is applicable for a vast number of general industrial and civil equipment scenarios. In practice, TLLB’s engineering team that has produced over 12 million units of this type of bearings since 2008 finds that over 72% of equipment unexpected downtime related to bearing failure can be avoided by selecting formal qualified products from certified manufacturers.
Q: What core components make up a single row deep groove ball bearing?
A: A standard unit consists of 4 core parts: pressed steel or brass stamping cage, chrome steel ball rolling elements, integrated inner ring with raceway, and integrated outer ring with matching deep groove. Most models also support optional rubber or iron sealing covers to block dust and leakage of lubricant.
Q: What are the unique advantages of single row deep groove ball bearings compared with other bearing types?
A: It can bear both radial load and a certain amount of bidirectional axial load at the same time, runs at extremely low noise at high speed, requires minimal daily maintenance, and has a far lower total procurement cost than angular contact ball bearings or cylindrical roller bearings for general use cases.
- Confirm your actual load parameters (radial load, axial load, maximum rotating speed) before starting selection
- Check the installation space limitation to confirm the required inner diameter, outer diameter and width size
- Choose proper sealing type and lubrication mode according to the actual operating environment
- Verify the accuracy grade to match your equipment’s precision requirement
- Cooperate with qualified certified suppliers for pre-shipment quality inspection to avoid defective products

Industry consensus from 2026 Global Bearing Association report: For over 80% of common industrial transmission scenarios, standard single row deep groove ball bearings can completely replace high-cost customized bearing products to cut total operating cost by 35% on average.
Key Quality Control Standards for Qualified Single Row Deep Groove Ball Bearings
In practice, TLLB implements 17 strict testing procedures for every batch of single row deep groove ball bearings before delivery, to guarantee all products meet ISO 9001:2015 and ISO 14001 quality management requirements. Our actual test shows that products that pass full QC checks can extend the average service life by 48% compared with unqualified inferior products in the market.
Q: What test items are necessary for qualified single row deep groove ball bearings?
A: Core mandatory test items include dimension tolerance inspection, noise and vibration test, hardness test, grease compatibility test, high speed overrun test and salt spray test for 48 hours to confirm anti-corrosion performance.
Q: How to judge if a single row deep groove ball bearing is inferior defective product?
A: You can check from 3 aspects: 1) rough surface burr or uneven electroplating coating; 2) unsmooth rotation with obvious blocking or abnormal noise; 3) no clear production mark and brand logo on the end face of outer ring.
Common Application Scenarios of Single Row Deep Groove Ball Bearings in 2026
From TLLB’s recent 2025-2026 customer case data, over 45% of our single row deep groove ball bearing products are exported to 32 countries across Europe, North America, Southeast Asia and Oceania, covering multiple vertical industries.

Q: Can single row deep groove ball bearings be used in high-temperature working environments?
A: Standard general products are applicable for working temperature between -30℃ and 120℃. TLLB also provides customized high-temperature models that can work stably under 200℃ for special industrial scenarios.
Q: What is the average service life of a high-quality single row deep groove ball bearing?
A: Under correct installation and normal load working conditions, TLLB’s standard 6200 series single row deep groove ball bearings can reach over 80000 hours of rated service life, far above the 25000 hours industry average level.
Maintenance Tips to Extend Service Life of Single Row Deep Groove Ball Bearings
Correct daily operation and maintenance can effectively avoid premature failure of bearings, reducing equipment downtime cost significantly. In practice, equipment operation teams that implement regular maintenance rules can cut bearing replacement cost by 60% per year.
FAQs
Q: Do single row deep groove ball bearings need regular re-lubrication?
A: Sealed pre-greased single row deep groove ball bearings do not need extra lubrication for their whole service life. Open-type models should add proper lubricant every 3000 working hours to reduce friction and wear.
Q: Can single row deep groove ball bearings be disassembled and reassembled?
A: Standard integrated single row deep groove ball bearings cannot be separated, please do not disassemble them manually, which will lead to permanent damage of the internal structure and lose original accuracy.
Q: What is the minimum order quantity for TLLB’s single row deep groove ball bearings?
A: TLLB accepts sample order as low as 10 pieces, and for mass wholesale orders, the standard MOQ is 1000 pieces. We also support custom printing logo and special parameter requirements for bulk projects.
Q: What is the lead time for standard single row deep groove ball bearing orders?
A: For standard models 6000 to 6300 series that have sufficient stock, TLLB can arrange delivery within 3 working days. For large orders over 100,000 pieces, the maximum lead time is 15 working days.
