Bearings

Open Linear Bearings are constructed analogously to closed linear bearings but have a cut-out section along their entire length. They come in two varieties differing in the outer diameter of the sleeve and length. These are KB bearings (European type) manufactured by companies such as SKF, BOSCH REXROTH, INA and LM bearings (Japanese type) manufactured mainly by the Japanese company THK. These bearings also come in several variants. A relatively frequently used variant are open linear bearings in housings.

Adjustable linear bearings are a special type of bearing that can be adapted to the specific application by changing the tightness between the shaft and the bearing. They are precisely adjustable in terms of diameter and feed speed and are characterized by the ability to carry large loads. Bearings in an adjustable housing are a very good solution in the case of direct mounting.

We have adjustable linear bearings well-known manufacturers, including: IGUS, INA, QC, Rexroth or IKO in several size variants. Our consultants will help you choose the right bearing model.

Plain bearings

Sliding bearings are commonly used in various types of machines in many industries. They are an optimal solution that reliably transfers oscillating movements, compensating for any misalignment. Unlike rolling bearings, sliding bearings do not have intermediary moving elements. The construction of a classic sliding bearing is very simple because it consists of two surfaces – a moving (sliding) one, which is a cylindrical bearing shell, and a stationary (supporting) one. Rotational movement occurs here by sliding.

A wide selection of many types and models of sliding bearings is available, including: dry bearings, air bearings, hydrostatic bearings, hydrodynamic bearings, spherical bearings, oil bearings, pressed-in sliding bearings (clip-on), sliding sleeves, flanged bearings, thrust washers, piston rings. At the customer’s request, we can also import bearings with appropriate parameters and for any application.

Inch ball bearings are very universal and common, they can withstand many loads. These bearings are produced in many sizes and variants, depending on the application, required operating temperature, clearance or accuracy. In the case of ball bearings, and especially inch bearings, it is worth knowing the characteristics of the bearing’s operating environment when assembling an order, on the one hand, and the classification and markings of bearings, on the other hand.

Bearing assemblies

We have a huge selection of products in this area. At the request of our customers, we can also import bearing units to a specific specification.

Bearing units consist of a rolling bearing and a housing (casing). These are specially designed environments for optimal bearing operation. Bearing units consist of a housing available in various variants (e.g. pedestal, flanged) and in two types: split and non-split; they also consist of a grease nipple, spherical seat, cage and a steel or industrial plastic cover. Depending on the housing design, the plane can be parallel or perpendicular to the shaft axis. In split housings, it is possible to replace individual bearing elements. Bearing units are the best solution in a highly polluted environment because their housing provides a very high level of protection against dirt.

Special bearings

Depending on the specific working environment, we supply various types of special bearings, including: high-temperature bearings made of ceramic materials, bearings with special coatings that additionally protect against wear, corrosion or the flow of electric current, bearings designed to withstand high dynamic or static loads.

Special bearings are commonly referred to as special purpose bearings, characterized by features that allow them to work in unconventional environments and often in extreme conditions. They are often made of advanced materials, covered with a special coating, have unique design solutions and shapes. Special bearings may differ from standard bearings in the following properties: dedicated structure, type of materials used, size and weight, mounting method and lubrication method.

Combined bearings

Combined bearings are bearings in which more than one rolling element is used. Most often, they are a combination of needle-ball bearings or needle-roller bearings. Needle-ball bearings are characterized by the possibility of working on the transverse axis and simultaneously in the longitudinal direction. They usually do not have an inner ring, which allows for much greater rotation accuracy and smaller spread of radial clearance. The second type of relatively often used combined bearings are needle-roller bearings. They are used for high speeds, high radial loads with simultaneous occurrence of small axial loads.
