JFK roller bearing housings
JFK bearing units
- High radial load capacity
- Misalignment compensation
- Harsh conditions
- High structural strength
JFK roller bearing housings are cast iron units designed to accommodate spherical roller bearings in applications subject to high radial loads, heavy stresses, shocks, vibrations, and severe environmental conditions. Compared with ball bearing housings, they offer superior structural robustness and are designed to withstand the heaviest loads in heavy industry.
JFK Group offers housings for spherical roller bearings in the most common configurations: pillow block, flange, and cartridge housings. The cast iron housing provides high mechanical strength and good damping capacity. Misalignment compensation is provided by the integrated spherical roller bearings, which accommodate significant angular misalignment without compromising performance. Each unit is supplied complete with bearing, seals, and lubricant.
Versions
How to choose the right roller bearing housing
The choice of configuration depends on the available mounting structure and the direction of the loads to be supported.
Spherical roller bearing housings
Horizontal mounting · Standard configuration · Cast iron pillow block housingsAlso known as roller bearing pillow block housings, these units are mounted on horizontal surfaces with the shaft parallel to the mounting surface. This is the standard configuration for most heavy-duty industrial applications. Cast iron housing with integrated lubrication holes and grease fitting.
Flange bearing housings
Wall mounting · Two or four mounting holes · Cast ironMounting on walls, vertical structures, or surfaces perpendicular to the shaft. Available with two or four mounting holes. Cast iron housing with integrated lubrication holes and grease fitting.
Cartridge bearing housings
Cylindrical body · Existing housing · Cast ironFor existing cylindrical housings. The cylindrical housing body is inserted into the housing by pressing or with an interference fit. Suitable for installations where the structure already features a cylindrical housing.
Performances
Design and performance features
Cast iron housing with integrated spherical roller bearings for high radial loads and severe operating conditions.
High radial loads and demanding operating conditions
Designed to withstand high radial and moderate axial loads in applications subject to shocks, vibrations, and severe environmental conditions. Higher load capacity than ball bearing housings.
Dynamic misalignment compensation through spherical roller bearings
The integrated spherical roller bearings accommodate significant angular misalignment between the shaft and housing, even during operation, without compromising performance.
Cast iron for maximum robustness
The cast iron housing provides high mechanical strength, good vibration damping capacity, and long service life, even under the most severe operating conditions.
Lubrication hole with integrated grease fitting
Equipped with a lubrication hole and integrated grease fitting for periodic bearing relubrication. The relubrication frequency depends on the operating conditions.
Pillow block, flange, cartridge
Available in the three main configurations to suit any mounting structure.
Mounting
Installation of spherical roller bearing housings
Roller bearing housings are secured to the structure using bolts through the mounting holes in the housing. The shaft is inserted into the bearing bore and secured using set screws or a locking ring on the inner ring. Misalignment compensation is provided by the integrated spherical roller bearings, which self-align automatically during installation and operation.
Mounting methods
- Securing the housing to the structureSecure the housing body to the structure using bolts through the designated mounting holes. For cartridge housings, press the housing body into the cylindrical bore using a suitable tool.
- Shaft insertion and securingInsert the shaft into the bearing bore. Secure the inner ring to the shaft using set screws or a locking ring. The self-aligning bearing automatically compensates for misalignment.
- Initial lubricationCheck the grease level in the bearing before commissioning. Add grease through the grease fitting if necessary. Establish the relubrication interval based on the operating conditions.
