The 16002 deep groove ball bearing is a compact, widely used bearing model designed for smooth rotation, low friction, and reliable performance in light to medium-duty applications. Because of its small size and versatile structure, the 16002 bearing is commonly found in motors, electric tools, household equipment, scooters, pumps, and other machinery where space is limited but stable performance is still essential.
For buyers, engineers, and maintenance teams, the 16002 bearing is attractive for one simple reason: it delivers dependable radial load support in a small footprint. It is also a standard part in the 16000 series, which makes replacement and sourcing easier across global markets.
In this guide, BYWB Bearing explains the 16002 bearing technical specifications, dimensions, sealing options, common applications, and the full 16000 series size chart from 16000 to 16010.
What is a 16002 deep groove ball bearing?
The 16002 bearing is a single-row deep groove ball bearing. “Deep groove” means the raceway grooves are designed to closely match the shape of the balls, which allows the bearing to carry radial loads efficiently and also handle a certain amount of axial load in both directions.
This type of bearing is popular because it offers:
- low friction
- quiet operation
- high rotational speed capability
- simple installation
- long service life when properly lubricated and sealed
The 16002 is part of the 16000 series, which is known for its slim cross-section and compact design. Compared with heavier standard series bearings, 16000 series bearings are often chosen when space, weight, and efficiency matter.
16002 bearing technical specifications
Although exact values may vary slightly depending on manufacturer and material grade, the standard 16002 bearing is commonly specified as follows:
- Bearing type: Deep groove ball bearing
- Series: 16000 series
- Bore diameter (d): 15 mm
- Outer diameter (D): 32 mm
- Width (B): 8 mm
- Basic dynamic load rating: approximately 6.7 kN
- Basic static load rating: approximately 3.4 kN
- Limiting speed: depends on lubrication, cage design, and sealing type
- Standard cage: steel cage, brass cage, or polyamide cage depending on version
- Material: chromium steel (GCr15 / equivalent bearing steel) is common
- Lubrication: grease or oil, depending on application
- Operating characteristic: low noise, low vibration, and smooth rotation
The exact load rating and speed limit should always be confirmed with the manufacturer’s catalog, especially when selecting bearings for high-speed motors or precision equipment.
For many customers, the most important technical point is that the 16002 bearing is a slim, small-bore bearing with strong performance in compact assemblies.
16002 bearing dimensions
The standard dimensions of the 16002 bearing are:
- Inside diameter (ID / bore): 15 mm
- Outside diameter (OD): 32 mm
- Width: 8 mm
So, the size can be written as:
15 × 32 × 8 mm
This compact dimension makes the bearing suitable for devices where the shaft is small and the housing space is limited. The 16002 bearing is often selected when a designer wants a bearing that is smaller than common 6000-series or 6200-series options but still needs reliable bearing life and speed performance.
Why the dimensions matter
The 16002’s slim structure gives it several advantages:
- easier integration in compact machinery
- lighter overall equipment weight
- reduced rotational resistance
- more design flexibility in tight spaces
At the same time, because the bearing is smaller, correct selection of load, speed, and lubrication becomes more important. If the application is heavily loaded or exposed to contamination, a stronger or better-sealed bearing version may be needed.
16002 bearing sealing solutions
A bearing’s sealing design is one of the most important factors affecting service life. For the 16002 bearing, the right sealing solution depends on environment, speed, maintenance access, and contamination risk.
1. Open type
An open 16002 bearing has no seal or shield. It is suitable for applications where:
- the bearing is regularly lubricated
- contamination is controlled
- speed is high
- the system already uses oil lubrication
Open bearings generally offer lower friction than sealed versions, but they need more protection from dust and moisture.
2. ZZ / 2Z metal shield
The ZZ or 2Z version uses metal shields on both sides. These shields help block dust and larger particles while maintaining relatively low friction.
Advantages of ZZ / 2Z:
- good speed performance
- low friction
- better protection than open bearings
- suitable for clean or moderately clean environments
This is often a popular choice for electric motors, fans, and general machinery.
3. 2RS rubber seal
The 2RS version uses rubber seals on both sides. This gives stronger protection against dust, moisture, and contamination.
Advantages of 2RS:
- better sealing performance
- improved grease retention
- more suitable for harsh environments
- longer maintenance intervals in dusty conditions
Possible trade-off:
- slightly more friction than metal shielded bearings
- not always ideal for very high-speed applications
Which sealing solution is best?
The best option depends on the working environment:
- High speed, clean condition: open or ZZ
- Dusty, wet, or outdoor use: 2RS
- Long life with low maintenance: 2RS or high-quality ZZ with proper grease
For many customers, the most common question is not just “What is the 16002 bearing?” but also “Should I choose open, ZZ, or 2RS?” The answer depends on the application and operating conditions.
What is 16002 bearing used for?
