Load capacity

The load capacity of NICE® Ball Bearings is a critical factor in their design, determining the maximum weight they can support without failure. Each series is rated for specific radial and axial load capacities, allowing for appropriate selection based on application needs.

• For example, the 1600 Series can handle radial loads up to 1,500 lbs, making it suitable for medium load applications. In contrast, the 400 Series, with a full complement design, can support higher radial loads, often exceeding 2,000 lbs due to its unground design that maximizes load-carrying capability.
• The axial load capacity varies by series but can reach up to 500 lbs for specific configurations in the 500 Series, which is designed to handle both radial and thrust loads.

Bore sizes and dimensions

NICE® Ball Bearings are available in a range of bore sizes and dimensions, allowing engineers to find the ideal fit for their machinery.

• The 1600 Series offers bore sizes ranging from 3/16″ (0.1875″) to 1 5/16″ (1.3125″), accommodating various shaft sizes. The 3000 Series has a bore range of 3/16″ (0.1875″) to 1″ (1.000″), allowing for flexible integration into existing systems.
• For the 400 Series, bore sizes range from 3/16″ (0.1875″) to 2″ (2.000″), making these bearings versatile for applications where space is limited but load capacity is essential.

Material and construction

The construction materials of NICE® Ball Bearings are selected for durability and performance. Most bearings are made from high-quality AISI 52100 chrome steel, known for its excellent hardness and wear resistance.

• Bearings may undergo a heat treatment process that increases hardness to approximately 60-65 HRC (Rockwell Hardness), enhancing their ability to withstand heavy loads and reduce wear over time.

Sealing options

To protect against contaminants and extend bearing life, NICE® Ball Bearings are offered with various sealing configurations:

• Open bearings: These allow for easy lubrication but offer minimal protection against dirt and debris.
• Shielded bearings: Typically come with a single shield that offers some protection while allowing for lubrication. These are often rated for applications where light contamination is a concern.
• Sealed bearings: These feature rubber or metal seals that provide maximum protection against contaminants. For example, the 6900 Series sealed options are rated for operation in environments where dirt and moisture are prevalent, ensuring longevity and performance in harsh conditions.

Operating temperature range

NICE® Ball Bearings are designed to operate effectively within a specified temperature range:

• Standard operating temperature ranges for most series are from -40°F to 250°F (-40°C to 121°C). However, some specialized bearings may endure temperatures as high as 300°F (149°C), making them suitable for high-heat applications.

Grease and lubrication options

Proper lubrication is vital for the efficiency and longevity of NICE® Ball Bearings.

• NICE® bearings can be lubricated with various types of grease, including lithium-based greases, which can operate effectively at temperatures up to 250°F (121°C). For high-performance applications, synthetic greases are available, which can extend the lubrication intervals significantly— often up to 5,000 hours in moderate conditions.
• The recommended lubrication interval can vary based on the application but is generally suggested to be every 3 to 6 months for most standard operating environments.
