SKF USA Inc. is the U.S. subsidiary of SKF Group, a world leader in rolling bearings and related technologies including sealing solutions, lubrication systems, and mechatronics (combining mechanics and electronics into intelligent systems). SKF USA is a major provider of products and technology to original equipment manufacturers and industrial operations in virtually every industry including transportation, paper, mining, oil and gas, food and beverage, machine tool, metals, aerospace, and energy.

SKF groups its technologies into five platforms: bearings and units, seals, mechatronics, services, and lubrication systems. By utilizing capabilities from these platforms, SKF develops tailor-made solutions to help customers improve performance, reduce energy use, and lower total costs.

Product Groups


Unmounted Ball Bearings

Deep Groove Ball Bearings

  • Low friction and running temperatures, low noise and vibration
  • High running speeds
  • High quality and performance capabilities for your application
  • Accommodate radial loads and axial loads in both directions
  • Available with a variety of greases for most conditions
  • Increased reliability and provide long bearing and lubricant service life

Insert Ball Bearings (Y-Bearings)

  • Different locking methods enable quick and easy mounting onto the shaft
  • Spherically shaped outside surface enables initial misalignment by tilting in the housing
  • Different sealing solutions for applications with high contamination levels
  • Reduced noise and vibration levels

Angular Contact Ball Bearings

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads (simultaneous radial and axial). The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases.

Other Ball Bearings


Unmounted Roller Bearings

Cylindrical Roller Bearings

  • High load carrying capacity, high stiffness
  • Low friction and high axial load carrying capability
  • The logarithmic roller profile reduces edge stresses
  • The surface finish on the contact surfaces forms a hydrodynamic lubricant film
  • Separable components facilitate mounting, dismounting, and maintenance inspections

Needle Roller Bearings

SKF needle roller bearings have cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend service life.

Tapered Roller Bearings

SKF tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. The construction accommodates combined loads and provides low friction operation. By adjusting one single row tapered roller bearing against a second tapered roller bearing and applying a preload, a rigid bearing application can be achieved.

Spherical Roller Bearings

SKF spherical roller bearings have high load carrying capacity and the ability to accommodate misalignment. They are robust, low friction, and have a long service life. Available in both open and sealed variants.

Other Roller Bearings


Bearing Accessories

Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat, as they can be used on plain shafts or stepped shafts.

Withdrawal sleeves are used to mount bearings with a tapered bore onto the cylindrical seat of stepped shafts. The sleeve is pressed into the bore of the inner ring, which abuts a shaft shoulder or fixed component. The sleeve is located on the shaft by a nut or an end plate.

Lock nuts are used to locate bearings onto a shaft. They can also be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves, and to dismount bearings from withdrawal sleeves. Lock nuts are frequently used to secure components like gears and belt pulleys.

Engineered Products

Track Rollers

  • Cam rollers (yoke-type track rollers based on ball bearings) are designed to run on all types of tracks
  • A thick-walled outer ring enables high radial loads, while reducing distortion and bending stress
  • Double row cam rollers accommodate higher tilting moments than single row
  • The crowned outer ring running surface is beneficial for applications where outer ring tilting relative to the track may occur or where edge stresses need to be minimized
  • Relatively high speed capability

Super Precision Bearings

SKF super-precision bearings offer high running accuracy, high-speed performance, and high system rigidity. They are ideal for machine tools and other precision applications such as rolling mills, racing cars, and marine vessels. They also minimize noise, vibration, and heat generation.


Spherical Plain Bearings and Rod Ends

Spherical plain bearings are mechanical components that enable multi-directional, self-aligning movements. The inner ring has a spherical convex outside diameter, while the outer ring has a corresponding concave inside diameter. The forces acting on the bearing may be static or may occur when the bearing makes oscillating, tilting, and slewing movements at low speeds.

Rod ends consist of a spherical plain bearing in the eye-shaped head of the rod end housing. They are primarily used on the ends of hydraulic or pneumatic pistons to join the cylinder to an associated component via an internal (female) thread, external (male) thread, or a welding shank


Bushings, Thrust Washers, and Strips

Bushings are suitable for rotating, oscillating, and linear movements. Straight (cylindrical) bushings can accommodate radial loads only and flanged bushings can accommodate radial and axial loads in one direction.

SKF composite dry sliding thrust washers and sliding strips are designed for applications where axial space is limited, maintenance is not possible, and where lubricant starvation can occur. Strips can be bent, pressed, or coined to form flat linear guides.


Mounted Bearings

Ball Bearing Units (Y-Bearing)

Ball bearing units are used in many industrial applications because of their versatility and cost-effectiveness. They consist of an insert bearing mounted in a housing. An insert bearing is a deep groove ball bearing with a sphere-shaped outside surface and an extended inner ring that has a mechanism to lock the unit onto the shaft.

Roller Bearing Units

Roller bearing units are ready-to-mount bearing units that are assembled, lubricated, and sealed at the factory for maximum service life. Styles include bearing units with a pillow (plummer) block housing, including a relubrication-free variant, and units with a flanged housing. All bearing units are available as locating (held) or non-locating (free) units.

Other Bearing Units

Bearing Housings

Bearing housings support bearings and protect them from contaminants while keeping in lubricant, and can also house monitoring equipment. They provide solutions to help maximize performance, service life, and cost-efficient maintenance of the incorporated bearing.

Seals

Power Transmission Seals

CR Seals logo picFounded in 1878 as Chicago Rawhide, CR Seals has one of the longest histories in the seal industry. For the last 110+ years, CR Seals has been setting performance and service life standards for industrial and automotive shaft seals.

CR Seals has also been part of SKF since 1990, a span during which they’ve developed new materials, manufacturing processes and designs to create some of the most robust seals on the market. CR Seals is represented as Power Transmission Seals in SKF.
