Bearings with Profiled Outer Rings
GRW profiled roller ball bearings are double-row angular contact ball bearings with an outer ring profile. GRW offers profiled roller ball bearings and rails in both standard and special designs.
GRW profiled roller ball bearings are designed in a way that is comparable to double-row angular contact ball bearings; for this reason, they are able to take axial loads in both directions, as well as high radial loads.
On request, other contact surface designs are available (e.g. V groove, spherical outer ring, etc.).
Inner and outer rings can be made from chrome steel or corrosion-resistant steels. The balls are made of chrome steel or ceramic. GRW profiled rollers are equipped with non-contact shields. On request, contact seals (e.g. Teflon, NBR) are available as an alternative. The rollers are lubricated for life. On request, they are also available with FDA-approved lubricants or lubricants that can with stand auto-claving.
