6316 Bearing Specifications

The 6316 bearing is a singlerow deep groove ball bearing designed primarily for radial load applications, though it can also accommodate limited axial loads in both directions. Below are its primary specifications:
- Inner Diameter (Bore): 80 mm
Outer Diameter: 170 mm
Width: 39 mm
Basic Dynamic Load Rating (C): 130 kN
Basic Static Load Rating (C₀): 86.5 kN
Reference Speed: 8,500 r/min
Cage Material: Sheet metal
Weight: 3.65 kg
Tolerance Class: ABEC1
Radial Clearance: CN
Ring & Ball Material: Chrome steel
Temperature Range: –30 °C to +110 °C
These specifications ensure that the 6316 bearing can withstand heavy radial loads, deliver highspeed capability, and maintain dimensional stability under varying thermal conditions.
What Size Is a 6316 Bearing?

When selecting a bearing for your application, understanding its exact dimensions is crucial for proper fit and function. The 6316’s size parameters are as follows:
Bore Diameter (d): 80 mm
Outer Diameter (D): 170 mm
Width (B): 39 mm
Bore Tolerance: –0.015 mm to 0 mm
Outer Diameter Tolerance: –0.025 mm to 0 mm
Width Tolerance: –0.150 mm to 0 mm
These dimensional tolerances ensure a precision fit in housings and shafts, reducing the likelihood of play or interference that could lead to premature wear.
6316 Bearing Seal Solutions

Sealing is vital for protecting the bearing’s interior from contaminants and retaining lubrication. The 6316 can be supplied in several sealing configurations:
- Open (No Seal):
Maximizes speed capability
Suitable for clean environments where external seals or shields are provided
- Metal Shields (2Z or ZZ):
Noncontact metal shields offer moderate protection against debris
Permit high speeds with minimal increase in friction
- Rubber Contact Seals (2RS):
Doublelip nitrile rubber seals provide superior exclusion of moisture, dust, and contaminants
Ideal for harsher environments, though maximum speed is slightly reduced
- Labyrinth Seals:
Customengineered for extreme environments where heavy contamination is present
Combine sealing lips and protective lips for staged protection
- Hybrid Solutions:
Shield on one side, seal on the other for balanced performance
Offers a compromise between speed capability and contamination resistance
Selecting the right seal solution depends on your application’s speed requirements, environmental conditions, and maintenance intervals.
What Can 6316 Bearing Be Used For?
The 6316 bearing’s design makes it suitable for a broad spectrum of applications:
Electric Motors:
From large industrial drives to household appliances, its highspeed capability and low noise make it ideal for motor shafts.
Automotive Transmissions & Wheel Hubs:
Its robust load ratings and precise tolerances ensure smooth power transfer and long service life under centrifugal loads.
Gearboxes & Reducers:
Accommodates radial and limited axial loads, essential in multistage gearbox arrangements.
Pumps & Compressors:
High dynamic load ratings support the radial forces generated by impellers and pistons.
Material Handling Equipment:
Conveyors, roller tracks, and crane wheels benefit from its durability and low maintenance needs.
Agricultural Machinery:
Thrives in dusty, wet environments common in farming applications, especially when fitted with proper seals.
Home Appliances:
Washing machine drums, dryers, and HVAC fans rely on its quiet operation and longevity.
Industrial Automation & Robotics:
Precision, low friction, and adherence to tight tolerances are critical in automated systems and robotic joints.
With its versatile load capacity, speed rating, and sealing options, the 6316 bearing is an excellent “goto” choice for engineers across these sectors.
