JFK bearing units
Ready to install, for every operating condition
Ball bearing units, roller bearing units, and bearing inserts: the complete range for supporting rotating shafts in every industrial application.
JFK bearing housings are complete, ready-to-install units, designed to simplify installation and ensure long-term reliability. Available in cast iron, pressed steel and technical plastic for ball bearings, and in heavy-duty cast iron for spherical roller bearings in demanding applications. Completing the range are the insert bearings themselves: self-aligning ball and roller units with a spherical or cylindrical outer surface to compensate for misalignment. Each bearing housing is selected for its verified quality, with availability and technical support guaranteed at every stage of the project.
Bearing housings are complete, ready-to-install units consisting of a housing (made of cast iron, pressed sheet steel, or engineering plastic) that accommodates a bearing and is mounted directly to the structure. They support rotating shafts without requiring precision machining of the housing seat. JFK bearing units cover the complete range: cast iron, sheet steel, or plastic ball bearing housings for lighter loads and aggressive environments; robust cast iron roller bearing housings for demanding applications; and bearing inserts—self-aligning ball and spherical roller units—for replacement or custom configurations.
Each bearing housing guarantees verified quality, with availability and technical support ensured at every stage of the project.

A complete range for every bearing support requirement
The three types of bearing housings cover the full range of requirements for supporting rotating shafts. Ball bearing housings are available in cast iron, pressed sheet steel, and engineering plastic for lighter loads and aggressive environments. Roller bearing housings provide robustness and high load capacity for demanding applications. Bearing inserts complete the range as replacement components or for integration into JFK housings.
JFK roller bearing housings
Cast iron housings for spherical roller bearings, designed for applications subject to high loads, shocks, vibrations, and severe environmental conditions. They compensate for shaft misalignment and support high radial loads and moderate axial loads. Used in material handling, heavy industry, quarries, and agricultural machinery.
JFK bearings for bearing units
Self-aligning ball and spherical roller bearings designed for use with dedicated housings. The spherical outer surface compensates for alignment errors, reducing wear and stress. Each JFK bearing housing is supplied complete with bearing, seals, and lubricant. Also available in relubricable versions with lubrication holes in the outer ring.TECHNICAL COMPARISON
Which housing for which application
A concise comparison by material and load capacity. Selection depends on the operating conditions of each application.

| Ball bearing housings - Pressed sheet steel | Pressed sheet steel | Low/medium |
| Ball bearing housings - Engineering plastic | Engineering plastic | Low |
| Roller bearing housings | Cast iron | High |
SELECTION GUIDE
Start by identifying the operating conditions
JFK bearing housings cover a wide range of applications: from lighter loads in aggressive environments to heavy-duty applications subject to shocks and vibrations, as well as installations where ease of mounting is the critical parameter. Start with the operating condition that best describes your application.
Moderate or heavy loads, mounting on a structure
Cast iron housings are the most widely used choice for moderate and heavy loads, featuring a robust one-piece structure and an integrated lubrication hole. They are available in the most common configurations, including UCP two-bolt flange units, or in pressed sheet steel for lighter loads where cost is the critical parameter.
Humid, food-processing, or chemically aggressive environments
Engineering plastic housings combine corrosion resistance, lightweight construction, and ease of cleaning. Compatible with steel or stainless steel bearings, they are the ideal solution for environments where metal housings would be exposed to corrosion or contamination.
High radial loads, demanding operating conditions
When loads are high and operating conditions are severe — shocks, vibrations, dust, and contaminants — spherical roller bearing housings provide the structural robustness and long service life that ball bearing housings cannot offer.
Replacement or integration into existing housings
Bearing inserts are the ideal choice when only the bearing inside an existing housing needs to be replaced, or when configuring a customized unit by combining a housing and bearing with the characteristics best suited to the application.Have a specific requirement?
