Suitable bearing types for every bearing housing model
All bearing types, with their unique technical properties, fit every housing model!
Extreme Bearing units can be configured with a wide range of bearing types, each offering unique characteristics and performance benefits, providing a tailored solution to meet your exact requirements!
Double row spherical roller bearings
Double row spherical roller bearings are used when very heavy radial and axial loads must be supported, or when shaft misalignment, shock loads, or vibration are expected.
Tapered roller bearing
A tapered roller bearing is used when the application involves combined radial and axial loads, especially when high load capacity and rigidity are required.
Sealed double row spherical roller bearings
Standard spherical roller bearings are already extremely good bearings from a mechanical point of view. Sealed Double Row Spherical Roller Bearings were developed for more contaminated conditions and difficult lubrication
Double row deep groove ball bearing
A double row deep groove ball bearing is used when reliable performance is needed at higher speeds under mainly radial loads, with moderate axial loads in both directions.
Self-aligning double row ball bearing
A self-aligning double row ball bearing is used when the application requires higher speed, lower friction, and lighter to moderate loads rather than maximum load capacity.
Single-Row Roller Bearing
A single-row roller bearing is chosen for higher rotational speeds and lower loads, with the added benefit of integrated seals that keep the rolling elements protected even when the housing seals wear.
Axial Thrust Roller Bearings
Axial thrust roller bearings are designed for high axial (thrust) loads acting parallel to the shaft, with a self-aligning spherical track and very high axial load capacity.
Bearing shaft retaining
Extreme bearing units can be mounted on the shaft using mechanical locking (set screws or a locking adapter) or by an interference fit, achieved either through a press fit or by using a retaining compound such as Loctite. Mechanical locking simplifies installation and removal, while interference-fit mounting provides better concentricity and torque transmission.
| Mounting Method | Shaft Damage | Torque Capacity | Ease of Removal | Cost |
|---|---|---|---|---|
| Set Screws | High | Medium | Good | Low |
| Locking Adapter / Sleeve | None | Very High | Good | Medium-High |
| Press Fit | None | Very High | Poor | Medium |
| Loctite (Retaining Compound) | None | High–Very High | Poor | Low-Medium |
Summary: Set screws are simple and economical but can damage the shaft. Locking adapters/sleeves provide the most reliable mechanical fixation without shaft damage. Press fits and Loctite retaining compounds create an interference fit with excellent
Adapter sleeve mounting
Perfect, firmly concentric fit on the shaft.Mounting a bearing with an adapter sleeve is technically the best mounting option.
Set screw mounting
Easy, quick mounting with a set screw. Fast installation on a bare shaft, ideal for light to moderate load applications where quick assembly is required.
Cylindrical bore mounting
Cylindrical bore for mounting on a bare shaft. Slides onto a turned shaft seat for a precise interference fit—the most compact shaft fixation option.
