- Bearing assembly in aluminium design with rollers
- LVG is a 2-row angular roller bearing with aluminum housing and two integrated bearing elements. Franke bearing assemblies type LVG are suitable for highest load capacities.They convince by high rigidity, low rotational resistance and low weight.
- Ready to install
- Preloaded free from clearance
- Franke bearing assemblies type LVG are ready-to-use, complete bearings with integrated Wire Race Bearings. Designed as roller bearings, they absorb equal load from all sides and are insensitive to impact and vibration. The bearing assemblies are sealed from both sides and adjusted free from clearance. Due to the housing parts made of aluminum the weight is reduced by 60% compared to steel bearings.

The rotational resistance indicates the preload on the bearing assembly. It is dependent on the respective type and the race ring diameter. The values indicated in the diagram are standard values and can be aligned individually.
Radial and axial runout accuracy
The running accuracies indicated in the diagram are maximum values.
Strip cages for the LBK series
The band cage is segmented in the length required respectively and delivered fitted with balls and ready-to-use. The number of segments is dependent on the bearing diameter and the ball size. The band cage can also be created in one part for special applications.
Flat cages made of hard fabric, non-corrosive steel, brass.
It is mandatory to use a flat cage for temperatures exceeding 100 °C and with ball diameters larger than 20 mm. Special solutions, including complete non-corrosive properties or radiation resistance, are also possible.
Special cages in the form of band or prong-type cages are available for special requirements in terms of ambient conditions or mounting space.
Franke also delivers materials such as plastic, non-corrosive, brass and Teflon.
Larger bearings and bearing elements use washers to simplify adjustment between the separate inner and outer rings. The washers are made of non-corrosive sheet steel. It is sensible to include in the design specifications a theoretical initial gap of 0.5 mm for the adjustment.
By standard, the bearing assemblies are fitted with sleeve seals S120. Temperature: –30 °C to +80 °C (NBR).
Max. circumferential speed: 5 m/s.
The seals can be ordered by the meter in order to seal the construction (e.g. when using a bearing element). The joint is then bonded using adhesive agent Loctite 401®.
