Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads. They must not be subjected to any radial load. The bearings are very stiff and require little axial space.
SKF spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers
Insert bearings are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
Combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing. They can accommodate both radial and axial loads. They are particularly suitable for applications where other types of locating bearing arrangements occupy too much space, or where the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for arrangements with simple thrust washers.
Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
Double row full complement cylindrical roller bearings incorporate a maximum number of rollers, as they are not equipped with a cage.
Ball bearing units consists of pre-lubricated ball bearings and a housing which varies in shape.
They are capable of aligning themselves efficiently using the spherical fitting surface between the bearing and housing, effectively preventing overloads due to misalignment.
SKF flanged roller bearing units consist of a spherical or tapered roller bearing mounted in a cast iron housing that can be bolted to a machine wall. The units are sealed and lubricated and ready to use. This assortment of units covers a wide range of requirements. Both metric and inch series are not standardized, but SKF roller bearing units are dimensionally interchangeable with most common designs in the marketplace.
The SKF take-up ball bearing unit assortment comprises insert bearing series and designs, with the main differences between the take-up units being the housing design, the locking method onto the shaft, the sealing solution, and the options for end covers and back seals. Explore the variety of take-up units and possible combinations available in the product details below.
Take-up units are typically mounted in take-up frames and are connected by an adjustment screw.
SNL plummer (pillow) block housings are the most popular bearing housings on the market, developed to be the first choice for design, quality and economy. They enable the incorporated bearings to achieve maximum service life with less need for maintenance. Different housing variants and seal designs are available, making the use of tailored housings virtually unnecessary and enabling cost-effective bearing arrangements to be made.
