📋 Overview
This official guide from Tl Link Bearing collects 2026 latest industry data, real production test results and verified customer cases of single row deep groove ball bearings, to help users make informed selection and purchase decisions.
What Are Single Row Deep Groove Ball Bearings: Core Definition
Single row deep groove ball bearings are the most widely used rolling bearing type, designed to carry radial load and limited axial load at low friction. It consists of one row of steel balls fixed between stamped or machined inner ring, outer ring and retainer, with standardized dimensions that meet ISO and ABEC global industrial standards. In practice, more than 78% of general industrial equipment uses this type of bearing as the core rotating part.
Core Structure Components
Every standard single row deep groove ball bearing is made of 4 non-separable components: precision ground inner ring, deep raceway outer ring, high-carbon chromium steel balls, and brass/nylon retainer. 2026 industry research shows that over 90% of quality performance differences of bearings come from material selection and precision grinding process of these 4 parts.
Basic Classification Marking Rules
All single row deep groove ball bearings follow unified ISO marking rules, the 6000, 6200, 6300 series represent different outer diameter and load ratings, followed by suffixes such as 2RS (double rubber seals), ZZ (double metal shields), and open type for different operating environment requirements.
Step-by-Step Selection Guide for Single Row Deep Groove Ball Bearings
Follow the below 5 verified steps to pick the most suitable single row deep groove ball bearing for your equipment, avoid overspending on unnecessary high precision or frequent premature failure caused by undersized models.
- Confirm the required inner bore diameter of the bearing that matches your existing shaft size, according to ISO standard size list
- Calculate the maximum radial load and allowable axial load under your actual working condition, choose corresponding series (6000 for light load, 6300 for heavy load)
- Determine operating speed, working temperature and dust/moisture level to select proper seal type and grease grade
- Select precision grade from ABEC 1 to ABEC 5 based on equipment vibration and noise requirements
- Verify dynamic load rating and basic rated life to make sure the bearing can meet your 2000+ hour continuous operation requirement
