Bearings
Bearing blocks: Reliable support for rotating shafts in any machine
What exactly are bearing blocks?
Bearing blocks, also called bearing housings, are clever combinations of an insert bearing and a housing. They ensure that a rotating shaft stays firmly in place, and with as little friction as possible. You'll find them in all kinds of machinery, from agricultural vehicles to conveyors and from food processors to filling machines.
Where are bearings block commonly used for?
Bearing blocks are versatile and are used in:
- Agricultural Equipment
- Conveyors and sorting systems
- Construction Machinery
- Food processing machines
- Packaging machines
- Filling machines for bottles and cans
- Textile Machinery
- Fans and industrial extraction
Different types of bearing blocks
Depending on the application, different types of bearings blocks are available:
- Hanging bearing blocks
For horizontal shafts - Flange bearing blocks
With mounting flanges, easy to assemble - Pillow bearing blocks
Robust and universally applicable - Tension Bearing Blocks
Ideal for applications with varying forces, - Self-aligning bearing blocks
Catch alignment errors cleanly
Self-aligning bearing blocks: smart and flexible
These consist of two parts:
- A strong cast iron body with a spherical bore and lubrication connection,
- A ball bearing with convex outer ring, double sealed and greased.
Thanks to this structure, they correct small deviations in alignment or shaft deflection, useful in dynamic machines.
What is a recessed bearing?
Recessed bearings are those that sit the bearing housing. They are very similar to standard ball bearings (series 62 or 63) and are made of hardened bearing steel. The cage is steel or reinforced plastic and are already filled with lubricant. Maintenance? Hardly needed. They run trouble-free between -20°C and +100°C.
Allowable misalignment by bearing type
- Regreasable bearings: up to ±3°
- Non-lubricated bearings: up to ±8°
- With protective cover: up to ±1°
The locking pin in the bearing housing prevents the outer ring from rotating with it, without affecting the angle of adjustment.
This is how to assemble cast iron bearing blocks
Cast iron bearing blocks are often delivered completely assembled. Still useful to know how assembly works:
- Check that the locking bolts are secure (not through the inner ring)
- Slide the block into place.
- Mount the block to the structure
- Secure the inner ring
After assembly: turn the shaft by hand and feel if everything goes smoothly. Then test at low speed and check the temperature periodically.
Two ways to attach bearings
- With locking bolts
- Easy and effective
- With an ecceentric ring
- The washer clamps onto the shaft. You turn the ring in the direction of rotation and secure it with a locking screw. This way, everything is firmly in place.
