About Ball Screw Support Bearings

Ball screw support bearings are specially designed for use in ball screw or lead screw applications. Most ball screw support bearings are angular contact bearings with a steep contact angle, such as 60°, and are available in duplex, triplex and quadruplex configurations. Other designs include bearings containing separate thrust and radial roller bearings in a single assembly. Cartridge designs are also available that include a housing, seals, and bearings.

Products & Services Related to Ball Screw Support Bearings

Ceramic Bearings
Ceramic hybrid bearings, the most common type of ceramic bearing, are constructed of steel inner and outer rings with ceramic (typically Si3N4) balls in place of steel.  Common types of ceramic bearings are angular contact and conrad.
Cylindrical Roller Bearings
Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but crowned or end-relieved to reduce stress concentrations.
Slewing Rings and Turntable Bearings
Slewing rings and turntable bearings can accommodate axial, radial and moment loads. They are not mounted in a housing or on a shaft, but are instead mounted directly to a seating surface via mounting holes.
Spherical Roller Bearings
Spherical roller bearings are self-aligning, double row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element.
Super Precision and Spindle Bearings
Super precision and spindle bearings are high-precision bearings that are designed for use in machine-tool spindles and other precision applications. Most super precision bearings and spindle bearings carry a high quality-rating such as ABEC-7 or ABEC-9, and run coolly and smoothly at high speeds.
Tapered Roller Bearings
Tapered roller bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller.
Thrust Bearings
Thrust bearings are designed for pure thrust loads, and can handle little or no radial load. The rolling element in a thrust bearing can be a ball, needle or roller.
