Read MoreThe 6202 bearing dimensions are: 15 mm inner diameter (bore), 35 mm outer diameter, and 11 mm width. This single-row deep groove ball bearing is one of the most widely used bearings in industrial and consumer applications worldwide. Whether you are replacing a worn component or specifying a new design, understanding these dimensions — and the tolerances around them — is critical for reliable performance.
Content
The 6202 bearing dominates its size class because it strikes an ideal balance between compactness and load capacity. With a bore of 15 mm, it fits the most common small-shaft diameters used in electric motors, pumps, bicycles, skateboards, and appliances. Its standardized dimensions — governed by ISO 15 and ABEC tolerance standards — mean that a 6202 bearing from any compliant manufacturer is interchangeable, reducing downtime and sourcing complexity.
The fundamental dimensional data for the 6202 bearing is defined by ISO standards and is consistent across compliant manufacturers globally.

The 6202 bearing has a dynamic load rating (C) of 7.65 kN and a static load rating (C₀) of 3.72 kN, making it suitable for moderate-load, high-speed applications such as small electric motors and power tools.

| Static Load Rating (C₀) | 3.72 kN |
| Fatigue Load Limit (Pu) | 0.160 kN |
| Reference Speed (grease) | 28,000 rpm |
| Limiting Speed (oil) | 36,000 rpm |

The correct 6202 variant depends on your sealing, lubrication, and clearance requirements. The base 6202 is an open bearing with no seals, while suffixed versions add protection and pre-lubrication.
| Part Number | Seal / Shield Type | Lubrication | Best For |
| 6202 | Open (no seal) | External / oil bath | Clean, oil-lubricated systems |
| 6202-Z | 1 Metal Shield (1 side) | Grease, partial protection | Light dust environments |
| 6202-2Z | 2 Metal Shields (both sides) | Pre-greased, lifetime lube | Motors, power tools, general use |
| 6202-RS | 1 Rubber Seal (1 side) | Pre-greased | Moderate dust / moisture |
| 6202-2RS | 2 Rubber Seals (both sides) | Pre-greased, fully sealed | Pumps, outdoor, humid/dusty |
| 6202-2RS/C3 | 2 Rubber Seals | Pre-greased | High-temp / thermal expansion apps |

Tolerance grades directly control the allowable deviation from the nominal 6202 bearing dimensions, and choosing the wrong grade can cause vibration, noise, and premature failure. Standard commercial bearings are P0 (ABEC 1), while precision applications demand P5 (ABEC 5) or P4 (ABEC 7).
| ISO Grade | ABEC Equivalent | Bore Tolerance (µm) | Typical Use |
| P0 | ABEC 1 | 0 / -8 µm | General machinery, appliances |
| P6 | ABEC 3 | 0 / -7 µm | Low-noise motors, better balance |
| P5 | ABEC 5 | 0 / -5 µm | Precision spindles, servo motors |
| P4 | ABEC 7 | 0 / -4 µm | CNC spindles, medical equipment |
| P2 | ABEC 9 | 0 / -2.5 µm | Ultra-precision instruments |

When selecting a deep groove ball bearing, engineers often evaluate the 6202 alongside its neighbors in the 62xx series. The 6202 sits between the smaller 6201 (12 mm bore) and the larger 6203 (17 mm bore), and choosing the right one depends on shaft diameter and available housing space.
| Bearing | Bore (mm) | OD (mm) | Width (mm) | Dyn. Load (kN) |
| 6200 | 10 | 30 | 9 | 5.10 |
| 6201 | 12 | 32 | 10 | 6.82 |
| 6202 | 15 | 35 | 11 | 7.65 |
| 6203 | 17 | 40 | 12 | 9.55 |
| 6204 | 20 | 47 | 14 | 12.8 |

The 6202 bearing's 15×35×11 mm envelope fits naturally into a wide range of rotating equipment. Its versatility is one reason it remains among the top five most ordered deep groove ball bearings globally.
Standard 6202 bearings use chrome steel (100Cr6 / AISI 52100) for rings and balls, which delivers the best balance of hardness, fatigue life, and cost for most applications.
Correct installation is the single biggest factor in achieving the rated service life of a 6202 bearing — improper force application during fitting causes over 30% of premature bearing failures according to industry studies.
The 6202 bearing measures approximately 0.5906 in (bore) × 1.3780 in (OD) × 0.4331 in (width). These are the converted equivalents of 15 mm × 35 mm × 11 mm. Note that the bearing is manufactured to metric tolerances; inch values are for reference only.
Yes. The outer envelope dimensions — 15 mm bore, 35 mm OD, 11 mm width — are identical across all 6202 variants. The rubber seals on the 6202-2RS are contained within the 11 mm width; they do not add to the overall bearing size.
C3 denotes a greater-than-normal internal radial clearance, typically 11–25 µm larger than standard C0. This is specified when the bearing will operate at elevated temperatures (above 50°C) or when mounted with a tight interference fit that reduces internal clearance during installation.
Yes. As a deep groove ball bearing, the 6202 can accept combined radial and axial loads. However, it is primarily designed for radial loading. The maximum continuous axial load should not exceed approximately 25–30% of the dynamic radial load rating (roughly 1.9–2.3 kN) under normal operating conditions.
The 6202-2RS bearing with standard polyacrylate rubber seals and lithium-based grease is rated for –25°C to +120°C continuous operation. For higher temperatures (up to +150°C), specify high-temperature grease and HNBR or PTFE seals when ordering.
Use a calibrated micrometer to measure the bore and OD, and a depth gauge for the width. For P0 grade, bore should read between 14.992 mm and 15.000 mm. Outer diameter should measure between 34.991 mm and 35.000 mm. Any deviation beyond these limits indicates a non-compliant or counterfeit bearing.
The 6202 bearing dimensions of 15 mm × 35 mm × 11 mm form the foundation of one of the most versatile and widely available deep groove ball bearings in the world. By understanding not just the nominal dimensions but also the tolerance grades, load ratings, suffix variants, and correct installation techniques, engineers and maintenance professionals can maximize service life and minimize unexpected downtime.
When specifying a 6202 bearing, always confirm the required tolerance grade, sealing type, and internal clearance class against your operating conditions. For standard industrial applications at moderate speeds and room temperature, the 6202-2Z (P0, C0) is the most cost-effective choice. For demanding environments, step up to 6202-2RS with C3 clearance, a higher tolerance grade, or a stainless/ceramic variant as needed.
