Linear Ball Bearings

INA from Schaeffler linear ball bearings KH and linear ball bearing and housing units of the compact range have a small radial design envelope and are economical. Their low radial section height automatically makes them attractive for applications in which only a small amount of radial space is available.

The bearings have an outer ring with openings and contain a ball and cage assembly with a plastic cage. The outer ring is formed and hardened. The balls undergo return travel along the openings in the outer ring.

The bearings are available in an open version and with lip seals on both sides (suffix PP). The end face seals have two seal lips; the outer lip prevents the ingress of contamination, the inner lip retains the lubricant in the bearing.

Features and Benefits

• Lower operating costs

• Reduced maintenance due to improved lubrication

• Lower heat generation

• Less noise

Product Application Information

Due to the closed design, these linear bearings are suitable for use on shafts.

Schaeffler KH14PP Series Ball Bearing, 14mm Inside Diameter, 21mm Outside Diameter - KH14-PP

This ball bearing is a high-performance linear ball bearing designed for applications requiring precision and reliability. With an inside diameter of 14mm and an outside diameter of 21mm, it is engineered to withstand significant loads, making it suitable for demanding environments. The sealed design enhances longevity by protecting it from contaminants.

Features & Benefits

• Offers high static load capacity of 760N
• Dynamic load rating reaches up to 830N
• Constructed from durable steel for robustness
• Features a polyamide cage for lightweight performance
• Both sides are sealed to prevent contamination
• Designed with CN clearance for effective operation

Applications

• Utilised in automated machinery for smooth movement
• Suitable for precision equipment in the electronics industry
• Ideal for linear motion systems in mechanical setups
• Employed in electrical needing reliable bearing performance

How does the sealed design benefit operation?

The sealed construction ensures that contaminants do not enter the bearing, which enhances its longevity and maintains performance in demanding conditions.

What are the implications of the CN clearance on functionality?

The CN clearance allows a fit that balances snugness and freedom of movement, making it suitable for applications that require both precision and the capacity to accommodate thermal expansion.

In what conditions should this bearing be used?

It is best suited for applications where exposure to contaminants is a concern, such as in dusty or humid environments, ensuring operational reliability.

What is the significance of the steel and polyamide materials used?

Steel offers strength and durability, while the polyamide cage reduces weight and friction, promoting efficient performance during operation.

How do the load ratings affect selection for specific applications?

The static and dynamic load ratings inform users about the maximum forces the bearing can handle, enabling informed decisions based on operational demands and ensuring reliability in various applications.
