Radial single - Import export

Although single row radial bearings are designed primarily to support a radial load, they perform relatively well under thrust or combined radial and thrust load with the added advantage of low noise, vibration, and drag torque. The internal architecture and cage selection can be designed to meet the specific needs of the application, from high speed to high load. Thin section deep groove ball bearings have a small radial cross-sectional thickness that are used when compactness is required. We manufacture deep groove ball bearings with a minimum bore diameter of 3 mm to a maximum outer diameter of 47 mm.

Double-row angular contact ball bearings are used in applications when heavy radial, thrust or combined loads demand axial rigidity of the shaft are required. This is similar to a duplex pair of single- row bearings due to its two rows of balls and angular-contact construction, which provide greater axial and radial rigidity than can be obtained by using a single-row radial bearing. We manufacture these ball bearings with a minimum bore diameter of 3 mm to a maximum outer diameter of 47 mm.

starlim//sterner is a recognized partner for the automotive industry and supplies OEMs with silicone and compound parts. There is no longer any car on the road without a starlim//sterner product. Most of the times it is hidden away under the motor hood and is present in plug connectors as sealant. Without such starlim//sterner products the car would be subjected to electrical shortages. Moisture would enter inside and incapacitate the vehicle. Production of silicone and multi-material parts for the automotive industry. For the auto-industry we produce amongst other things Sealing mats and collector seals Seals for plug connectors Highly transparent lenses Radial seals Single strand seals O-rings Protective tubes for spark plugs Steering wheel switches with finished surfaces Various customized solutions

KIS deep groove ball bearings are characterised by their high load carrying capacity and speed stability. Depending on the requirements of your application, they are available in different variants and in both radial and axial design. Our single row deep groove ball bearings are available in open and sealed designs. Open bearings are maintenance-free, while sealed bearings offer better corrosion protection. Single row deep groove ball bearings can support both radial and axial forces. Our double row deep groove ball bearings feature a higher radial load carrying capacity. They are used when the radial load carrying capacity of single row deep groove ball bearings is not sufficient. Axial deep groove ball bearings are suitable for supporting particularly high axial loads. They are available in both single and double direction. Single direction thrust ball bearings can only support axial forces, while double direction thrust ball bearings can support both radial and axial forces.

Angular contact bearings are designed so that the contact angle between the raceways and the balls is formed while the bearing is in use. The ability of angular contact ball bearings to withstand axial loads increases proportionally as the contact angle increases. Features of angular contact ball bearings: high stiffness ideal for high-precision performance at high speed able to withstand heavy axial loads and moderate radial loads available with a single or double row, in the open or shielded / sealed versions Series Single row: 7200, 7300 Double row: 3200, 3300, 5200, 5300 APPLICATIONS: Agricultural Machinery Metal processing Oil Industry Paper making machines Wind sector Gearboxes Pumps and Compressors Ventilators /Fans Semiconductors Motorcycle Industry Machine tools Electromechanics Textile machinery Injection molding machines
