LVC Angular 2 Row Specification
LVC Angular 2 Row
Product type
- Bearing assembly in steel design
- Integrated double-row angular ball bearing
- LVC is a bearing assembly designed as double-row angular contact ball bearing made of steel with two integrated bearing elements. Franke bearing assemblies in type LVC are suitable for the highest circumferential speeds. Convincing aspects include their high dynamism and low rotational resistance.
Characteristics
- Ready to install, wide selection range
- Preloaded free from clearance
- For high speed and acceleration
- Franke bearing assemblies type LVC are ready-to-use, complete bearings. The double-row angular contact ball bearing in 4-point adjustment is preloaded free of clearance. It is insensitive to impact and vibration. The low rotational resistance and the minimal breakaway torque reduce the necessary drive power. Bearing assemblies type LVC operate practically without maintenance and achieve a high service life due to the low friction values.
- From 100 – 1800 mm

Loadings
Rotational resistance
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.
Standard Cages
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.
Special Cages
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.
Washers
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.
Seals
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®.

Advantages
Maximum design freedom, without compromising precision or load capacity.
Principle
4 Point ContactFreedom of Design
4 Point contact principle to take load from all directions. the rolling process does not take place directly between the rolling elements and the mating structure, but rather on special race rings, giving maximum freedom of design.
Compact
Minimal Mounting SpaceMinimal Mounting Space
Requiring only a small mounting space, the compact and highly resilient four-point geometry of Franke Bearings gives you maximum freedom of design, making an ideal design component for your application.
Material
Unlimited Material ChoiceUnlimited Material Choice
Franke lightweight aluminum bearings are 65% lighter than steel, offering substantial design freedom. Available in a wide range of materials, from aluminium, bronze ceramic, plastic, carbon, 3D printed and many more.
