Full Complement Cylindrical Roller Bearings From 20 mm to 1200 mm
SL series full complement cylindrical roller bearings are guided by two flanges on one bearing ring, with rollers and guide rings forming a single assembly. They are separable, which makes mounting easy where the rings need an interference fit on both shaft and housing.
- Diameter range 20 mm to 1200 mm
- High radial load capacity
- Low noise at high speed
- Separable design for easy mounting and dismounting
Key Benefits
Why this construction is chosen.
Radial Capacity In The Same Envelope
Compared with a deep groove ball bearing of the same dimensions, this type carries a much larger radial load.
Easy Mounting And Dismounting
The separable design is easy to install and remove, especially where inner and outer rings both need an interference fit.
Low Friction At The Flange
Low friction between rolling elements and the ring flange supports high speed rotation with low noise.
Where It Is Used
Typical applications.
- Heavy radial load machinery
- High speed rotating equipment
- Gearboxes and drive units
- Metallurgical and industrial machinery
Who It Is For
- Plants specifying bearings for radial load positions
- Machine builders selecting bearings for new designs
- Maintenance buyers replacing SL series bearings
- Buyers needing large diameters up to 1200 mm
Problems It Solves
- Ball bearings reaching their radial load limit
- Difficult mounting where both rings are interference fitted
- Noise and friction at high rotational speed
- Sourcing very large bearing diameters
Technical Features
Design characteristics.
Two Flange Guidance
Bearings are guided by two flanges of one bearing ring, with rollers and guide rings forming a single assembly.
Separable Construction
The separable design simplifies installation and removal in tight interference fits.
Radial Duty With Limited Axial Capability
These bearings mainly carry radial loads. Only single row bearings with flanges on both rings take small or large intermittent axial loads.
Specifications
Boundary dimensions are selected from your housing and shaft.
| Series | SL full complement cylindrical roller bearings |
|---|---|
| Diameter Range | 20 mm to 1200 mm |
| Load Direction | Primarily radial |
| Axial Capability | Small or large intermittent axial loads only with flanges on both rings |
| Guidance | Two flanges on one bearing ring |
| Construction | Separable, easy to install and dismount |
| Characteristics | High load capacity, low noise, high speed |
Materials
- Bearing steel rings and rollers
- Ground raceways
- Guide rings per series
Manufacturing Process
Selection
Housing and shaft dimensions, load and speed define the series and size.
Ring Manufacturing
Rings are turned, heat treated and ground.
Roller Production
Rollers are ground and sorted for even load sharing.
Assembly And Inspection
The bearing is assembled, cleaned and clearance checked.
Quality Control
- Raceway geometry inspection
- Radial clearance measurement
- Hardness verification
- Noise and running test where specified
Customization Options
- Boundary dimensions across the 20-1200 mm range
- Clearance class for the installed fit
- Flange configuration per axial requirement
- Batch supply for planned maintenance
Use Guide
- Respect the interference fit values for both rings
- Mount with the separable design rather than forcing the assembly
- Keep lubrication clean for full complement bearings
- Order by the designation stamped on the existing bearing
How It Compares
Against other bearing types.
| Deep groove ball bearings | Much larger radial load capacity at the same boundary dimensions. |
|---|---|
| Caged cylindrical roller bearings | Full complement construction raises roller count and load rating in the same envelope. |
| Non separable bearings | The separable design makes mounting far easier where both rings are interference fitted. |

What sizes can you supply?
SL series full complement cylindrical roller bearings from 20 mm to 1200 mm diameter.
Can they carry axial load?
They are generally used for radial loads. Only single row bearings with flanges on both inner and outer rings can take small axial loads or large intermittent axial loads.
Why are they easy to install?
The design is separable, which helps particularly when the inner and outer rings both need an interference fit with shaft and housing.
How do they compare with ball bearings?
At the same dimensions they carry a much larger radial load and suit high speed rotation.
Can you match our existing designation?
Yes. Send the designation on the bearing or the boundary dimensions with the clearance class.
What do you need to quote?
Bearing designation or dimensions, load and speed data, clearance requirement and quantity.
