Single-row ball slewing bearings are available with internal or external gearing or without gearing.
The four-point contact bearing of the 01-series belongs to the most often used designs. We are able to produce them in diameters from 120 mm to 6,300 mm, with either hardened or unhardened gearing. We also deliver four-point raceway geometry, a preloaded raceway system, centering, special seals as well as various spacers or cages for applications at up to 350°Care.
The L-series includes a series of light profile designs, flange bearings with external, internal or without gearing. It is produced with race-way diameters from 310 mm to 1,455 mm (standard program). Models with double bores, reduced or preloaded clearance up to precision quality class, e.g. for machines, are available on request as well.
Excavators, Deep drilling systems, and other construction machines, welding construction, machine building and plant construction.
CRB’s 02-seriesis particularly suited to heavy loads.
These slewing bearings resist form deviations in the connecting construction and have a higher static load capacity than cross-roller slewing bearings constructed in the same shape. Hence this CRB product is particularly suited to challenging applications such as in wind turbines.
Our standard range for the eight-point bearings is between 500 mm and 4,500 mm.
Wind power plants, cranes, construction machines, engineering and plant engineering.
We manufacture the cross-roller slewing bearings of the 11-series with raceway diameters of up to 5,000 mm and roller diameters of 80 mm. They have a single-row roller raceway angled at 45° featuring a more uniform potentiometer at varying loads and a longer dynamic lifespan than equivalent ball slewing bearings.
They do however place higher requirements to the stiffness and accuracy of the connecting construction.
Triple-row roller slewing bearings from CRB Antriebstechnik are designed to carry heavy loads where little space is available.
They are characterised by the greatest dynamic loadcapacity, highest stiffness and most uniform potentiometer of all slewing bearings (of the same diameter). Their uniform load distribution also meets the highest demands regarding stiffness and precision of the connecting construction.
This product line can be provided with a diameter of 6,300 mm, in segments even up to 14 meters.
Products in the 13-series can be furnished with synthetic spacers or a closed cage depending on the intended application and demands. The cages are available in plastic, steel or brass.
Deep drilling systems, fire engines, articulated buses, steel plants, self-loading vehicles, cranes, ship loading equipment, harbor and wharf cranes, crawler cranes, offshore equipment.
The combined bearings from CRB are designed for very high axial loads.
This series is mostly used when large diameter versions are required.
Depending on customer requirements, we offer the combination bearing in various diameter sizes and any configurations.
Construction machinery, mining machinery, wind turbines, ship loaders and other off-shore applications.
With a machine park of CNC lathes, milling, drilling machines and machining centers with 5 axes, CRB is able to machine workpieces with up to 10 tons and a diameter of up to 2.5 meters in Leverkusen.
The ring-shaped parts are CRB’s main products. Castings and forgings can also be manufactured with the machines according to customer samples or drawings.
Your requirements are welcome. We develop and grow together with you.
Also consider CRB as your extended arm to East Asia, especially China. We look forward to your challenges.
