  • in Cylindrical Roller Bearings

    PSL's single row cylindrical roller bearings are suited for heavy radial loads operating under high speed, and are separable. They are manufactured in several basic designs, including axially firm (NUP, NH) - which can carry a certain axial load in both directions; axially loose (NU) - which allows the mutual displacement of the rings in both directions; and in the design (NJ, NUJ) - which carries the axial load in one direction.
  • in Roller Bearings

    PSL's production offering includes more than 200 types of both standard and special roller bearings. Single row tapered designs handle both radial and axial loads. Double row tapered types are used in heavy duty applications. Four-row tapered designs are suitable for large radial forces. PSL's single row cylindrical roller bearings are suited for heavy radial loads operating under high rotational speeds. For high radial forces it is suitable to use multi-row cylindrical configurations. Crossed taper roller bearings consist of tapered rollers and can handle radial loads in high rigidity applications. Double row spherical types can simultaneously accommodate heavy radial loads and axial loads in both directions. Bearing rollers are also available.

  • in Slewing Bearings

    PSL of America Inc. manufactures slewing ring bearings up to 157" in diameter. Available with gearless, internal or external gear configurations, the bearings can control axial, radial and tilting moment loads. The bearings are used in construction equipment, wastewater machinery, radar antennas, packaging machinery, rescue vehicles, aerials, fellerbunchers, tunnel machinery, drilling equipment, and cleaning and bottling machines.

  • in Spherical Bearings

    PSL is a manufacturer of double row spherical roller bearings that can handle heavy radial loads and axial loads in both directions. The outer ring raceway's spherical  shape enables mutual alignment in operation and secures uniform load distribution on the rolling elements. Other types of bearing products offered include bearing rollers, all types of roller bearings, and thrust ball bearings.

  • in Tapered Roller Bearings

    PSL is a manufacturer of tapered roller bearings including single, double and four row configurations. Single row tapered roller bearings are able to harness both radial and axial forces. Double row tapered roller bearings are used in heavier duty applications.  Four-row types are suitable for accommodating great radial forces and are most widely used in the roll neck areas of rolling mill equipment.

  • in Turntable Bearings

    PSL of America offers slewing bearings/turntable bearings that can be externally geared, internally geared or gearless, and range in diameters from 8 inches to 11 feet. The bearings are used in a number of applications including cranes, forestry equipment, aerial work platforms, excavators, torque hubs, gear boxes, wind turbines, rolling mill equipment, and deep space antenna equipment.
