SKF Thrust Ball Bearings Product Introduction

SKF thrust ball bearings are true "experts" designed specifically to handle one-way axial loads. They not only offer high precision but also operate with minimal friction. You'll find them working their magic in places where high axial stiffness and low rotational resistance are crucial, such as automotive transmissions, industrial gearboxes, pumps, and machine tools.

Core Features and Advantages

Versatile for Single and Double Directions

SKF offers two types of thrust ball bearings. The single-direction ones handle loads in just one direction, while the double-direction ones are even more impressive, capable of handling loads coming from both directions with ease.

Heavy-Duty Load Capacity

Thanks to the carefully designed raceways and balls with optimized shapes, these bearings can carry an incredibly large amount of axial load.

Ultra-Precise and Stable

Manufactured with extremely tight tolerances, meeting ISO P6, P5, or even higher standards, they're perfect for applications that demand high rotational accuracy.

Smooth and Low-Friction

Made with high-quality steel balls and precisely ground raceways, they consume hardly any energy during operation.

Tough and Durable

Available in open, sealed, and shielded types, they can adapt to all kinds of working environments.

Multiple Material Choices

Standard models are made from high-grade chrome steel (AISI 52100). If you're worried about rust, there are also corrosion-resistant versions made from stainless steel (AISI 440C).

Different Model Designs

Single-Direction Thrust Ball Bearings (511, 512, 513, 514 Series): Composed of a shaft washer, a housing washer, and a ball-cage assembly, they're great for handling one-way axial loads and can also resist some radial loads.
Double-Direction Thrust Ball Bearings (522, 523, 524 Series): With two housing washers and one central shaft washer, they're the "main players" when it comes to handling two-way axial loads in precision machinery.
Sealed/Shielded Models (e.g., 511 - 2Z, 512 - 2RS1): The "2Z" in the model number means double metal shields, and "2RS1" indicates double rubber seals, which do a great job of keeping dust and impurities out.
SP Series with Self-Correcting Feature: The spherical seat washers can automatically adjust for misalignments of up to 2 - 3 degrees. So, even if there's a small installation error, no problem!

Lubrication and Maintenance

Grease Lubrication: Standard models come pre-lubricated with SKF LGMT 2 grease or an equivalent, so they're ready to use right out of the box.
Oil Lubrication: For high-speed operations, ISO VG 32 - 100 oil is recommended to get the best performance out of the bearings.
Re-lubrication Intervals: It depends on the operating conditions, but generally, it's between 5,000 and 20,000 hours.

Application Areas

Automotive Industry: Indispensable for clutch release mechanisms and steering systems.
Industrial Production: Useful in pumps, compressors, crane hooks, and extruders.
Aerospace: You'll find them hard at work in actuators and flight control systems.

Quality Assurance

SKF thrust ball bearings fully comply with the ISO 104:2015 standard and have been tested under various extreme conditions for durability. Advanced manufacturing processes ensure consistent performance and a much longer service life than ordinary bearings. You can count on them with complete peace of mind!

Technical Parameters

Bore Diameter:	Ranging from 10 mm to 600 mm, there's a size to fit almost any industrial need.
Outer Diameter:	Varies by series, typically from 26 mm to 670 mm.
Dynamic Load Rating:	In heavy-duty applications, it can reach up to 500 kN-truly a force to be reckoned with.
Static Load Rating:	When facing extremely large axial loads, it can handle up to 1,000 kN without breaking a sweat.
Speed Limit:	Bearings lubricated with grease can run up to 3,000 rpm, and those with oil lubrication can go even faster, exceeding 5,000 rpm.
Operating Temperature:	Regular bearings work well between -30°C and +120°C, while high-temperature models can withstand up to +200°C.
